Started a thread like this on another forum. Open to everyone to post small projects or repairs that don't warrant a separate thread.

The other day I got a call from a chap wondering if I could look at his hydro plant. It needed the bearings changed on the turbine. OK, this sounds interesting.
He bought a farm a year or so ago complete with a 60 Kilowatt hydro plant. He can operate it about 9 months of the year, over the summer the flow in the creek is too low. Has about 12 foot of fall with a 36 inch pipe feeding the turbine. When running he sells power to the grid.
Even shut down theres enough leakage to spin the turbine. It was clunking away, but didn't sound like bearing problems. Put a screw driver as a stethoscope against the bearings and they sound fine. It has wickets that adjust the flow into the turbine, this controls the speed to stay at 60 hertz. I climb down into the cellar around the turbine and the little ball joints one of the arms that control the wickets is broken. Pull the arm on the wicket up and we have silence, and he has a grin on his face.
He's going to close the gate above the penstock and dewater the system. We'll replace all the ball joints and give it a going over.
Sorry no photo's my camera battery was dead and my phone camera has died. Will get some pictures when I go back to work on it.

You have done more in your shop than I have got in mine lately.   Finally got most of the Bath remodel stuff out of the way,  So I can start cleaning up and get back in.   First going up to Lindale TX, Tyler area, Sat,  and on to Branson  on Sun.   Wife want a vacation, and I get my epidural for the back today,   so I should be able to stand the car rides better.   Need to find something to do up in that area while she is shoping etc.  But that means the pain relief will be wearing down by the time I make it back into the shop again.

Yesterday, I worked on a 1000hp boiler (42 million BTUs) in a cream cheese/string cheese plant. Worked on the combustion tuning and some control issues.

Today, standing in the shop, watching out the shop’s overhead front door, seeing retirees walking their dogs and young mothers, pushing the strollers. Most of the young kids, scream with glee, when they see the big fluffy dog, but at his age, he couldn’t care less. I’m on hot stand by, allegedly anticipating a phone call to spring into action.

FedEx was supposed to have dropped off a package for today’s work, yesterday morning , showed up at 5:30 pm (so much for extra charges for over night delivery), they said they could not deliver as no one answered the door, as the wife and I were setting the living room, that was pure bullshit. He did leave the infamous can’t deliver tag. So now we are in the package location limbo, their tracking computer, does not know, if its on the truck for a second delivery attempt, setting in the warehouse or in a ditch somewhere They are waiting for a computer update/reboot/Armageddon. So we wait. Customer is irate, they have 18 people, standing around, with no actual production being done, for their work schedule, they have their customer deadline, and FedEx is very non committal on, where the package is, who has it, or if/when it we be delivered. I hate this business.

Meanwhile back at the ranch, the shop is a cool 65 degrees, the sun is out and the the forecast is great.

that was our whole summer hot and humid... now just humid.. we haven't had a clear day in 2 weeks.  I just cut the grass with a light rain it was too high, and I couldn't wait any longer.

I have been busy though. Multiple projects at once..
Ramps to move stuff to the basement.
A trolly to move the equip  into the stairwell, on the dolly. Made of wood, and skate wheels..

I rebuilt the magnetic chuck (I think I need a fine pole chuck) for the grinder it only holds really big pieces. Anything small can easily be moved. Maybe after I surface grind the chuck in a few months (after rebuilding the grinder) it will hold better, since it will be in absolute contact with the magnetic plate. The surface is quite dimpled.

where did you see the pandas?? I saw them at the Beijing zoo and at a panda reserve about 2 hours outside of Tianjin. The next day I visited the Great Wall of China.

Have you had an opportunity to visit any of their manufacturing facilities?? I saw some amazing Chinese CNC marching centers (think Haas or Mazak).

Way too hot today but spent the afternoon out in the sun cutting firewood.
Built this processor a couple of years back. Uses a 17 hp Kubota diesel, could have a little more power but cuts faster than any chain saw I'd want to hold. Has a single splitter, thats the slow part with big wood, but the 4 ways seam to make kindling or too big of blocks.
Having the shovel to load the bunks is a lot easier than the tractor.

As I was working, I get a text from a friend.

I cant get this nut to start on the axle, any sugestions?

(I didnt have time to answer, when I did get time more texts waited.)

I got it started, but it wont tighten up.

(A few minutes duration)

Its turning but wont tighten.

I think I stripped it.

Can you fix it?

( 20 minutes later)

Its in front of your shop, no rush, but I need it Monday.

Its good to have buddies with a machine shop!

Working on a custom R8 collet design mod  in CAD.   
Currently I’m trying to figure out how to program the helical toolpath for my rotary table.  I use Sprutcam to program my Tormach and 3 axis is pretty easy.
4th axis stuff is not something I have learned yet so its been quite challenging.

Decided to do something actually involving metal removal.   Chopped off the electrical connector ends on my old Z55 GM Autoride shocks.   Recently replaced them with Bilstein 5100’s
and man my 3/4 ton Burb rides so much better!   Problem is now I have the electrical connectors at each wheel to deal with.  For now I zipp tied baggies to protect them but eventually I need to add 3.9 ohm resistors in place of the old shocks to trick the computer and eliminate the ride contol MIL light.   Easy enough to simply cut the harness connectors and butt splice the resistors in but I like to keep the factory harnesses so me or future owner can go back to the stock $$ Autoride shocks.   
Seriously I invent my own “problems”

cruising down the yangtze river on the way home today. Missed the typhoon.The pandas were in the panda research station with heaps of babies, very cute.No chance for much sight seeing so no machining stuff.I will post a couple of pics when I get sorted out at home after the weekend.This was a flying visit for 6 days only for a looksie.Very impressed I could log into my live security cams from here

I got up, let the dog out, ate some English muffins and left for work. Garbage day, pulled the cans to the street edge. Filled up the service van, bought some Mt Dew Code Red. Started to the job, got a phone call, job postponed until next week, turned around and went home.

So got up 2 hour before I wanted to, drove round trip about 65 miles, accomplished absolutely nothing, on the plus side, the paycheck keeps coming.

Since the 20 ton Harbor freight press has seen little use, and was mainly in the way, I traded it, less the jack for an I beam trolly.
This happened on Sunday.
Monday morning I have a job that requires a press.  :-\
Soooooo, I have been wanting to make a smaller, mobil press that can be dissasembled and stowed easily.
I will use the 4 ton porta power for the ram, and make everything else from the scrap pile.
First order of busness was to make a mounting plate for the ram.

This was my first time ever to single point internal threads.
I screwed up and had the jaws too close on the inside of the hole, so I had a "non-sheduled" practice session of recentering a hole, and picking up a thread.
The threads were a little snug, and I left them that way, they will most likely get loose with repeated use.
To be continued.

So three POTD today.
First one was to weld on two additional D-rings on the dump trailer in preparation for the mill delivery to CA.

Second, rebuild the filter head on the Duramax. I lost prime last time I drove the rig and trouble shot a bad prime seal.
The black (smaller)  O-rings where flat. The replacements are Viton. Also added a .500" spacer to simplify removal of the filter.

Third was to turn a adaptor for a propellor. The reduction gearbox sprockets teeth where turned off and the larger end turned to fit snuggly into the props ID. The customer wants to wall mount the prop and run at slow RPM for effect.....Whatever man, I'll just machine the part.

My hands still stink of diesel :-\

How did you attack the teeth on the sprocket (interrupted cut from OD or were you able to trepan them off)?

Need to add some D-rings to my dump trailer. I lined it with 5/8 plywood to protect the sides from dents throwing in firewood. Will have to bolt them in.

Thanks Ray,
yeah, I took interrupt cuts at .060' increments. I use CXA tooling that don't really care. :) Turning the diameter down to 2.250" was sooth on that lathe. I suspect the sprocket was somewhat hardened as the blue chips flew off really hot.

Hi Greg,
judging by the size of logs you play with, its no wonder you need liners hahah. I mostly haul dirt but when I do haul river rock or smaller boulders, I just throw down a thick layer of sand.
The mill I'm hauling to CA will sit over the double axel, so I wanted additional anchor points. The four at each corner will also be used but having hauled in the state of CA before, I'm just taking precautions as some of those drivers are real dicks.
Thanks for following Greg.

My dump trailer is just a 5 x 8 foot single axle. Was going to go tandem but decided on this one with a 5K axle. The feds never look twice at a single axle trailer but love inspecting tandems. The dump is a godsend for me hauling firewood, shavings, sawdust, gravel. Nothing more disheartening than shoveling on a load of sawdust then having to unshuvel it.

Greg

Post by: firestopper on September 21, 2018, 10:22:04 AM
Avoiding any hassle is always good.
I'm lucky, here in AZ we can run permeant tags, so both trailers I run have them. The cops usually don't look twice unless your a business.  The dump is a handy feature, I use it a few times a year when I clear brush and trim trees around the property. It came in real handy when I was building the shop during the dirt phase.  Always seem to get dirty looks at the dump from at least one knucklehead while I'm dumping and he's hand jacking his load off hahah.

We run permanent trailer plates here too, but the mermaids don't hesitate to pull over private vehicles pulling a trailer of pickups. I try to keep a low profile and maintain equipment so haven't been stopped myself but know of plenty who have.

Of course it came halfway thru my rotab chuck mounting project which since im anal about my equipment means cleaning all the crs steel shavings to switch over to nylon
Carpenter84 your right I do keep my machines extremely clean but I can afford to since its a hobby shop.   I probably should take some “in progress” pics of my projects to prove they actually get used but my hands are usually grungy and the phone is hooked up cranking Spotify Lol ok how about the trash can with the remnants???   
(https://uploads.tapatalk-cdn.com/20180922/ed01fb69e5425d260054932821557061.jpg)
Then of course I went A.D.D and spent 1/2hr cleaning the end gear train on the lathe.   The oil on the gears slings around and mixes with belt shavings and gearbox oil so once in awhile I pull the cover and clean er up.

UB,
a 40 is short for FJ40 (Toyota Land cruiser).
It runs a 2F straight six with solid lifters.
1982 mostly stock with a 4" lift. We have emissions testing so its also "smogged" :'(.  She gets tested once a year, so I usually have to create a vacuum (large) leak and turn the idle to 1900 rpm to pass. Once she passes, I pull forward to a parking space and put her back to smooth running In front of the emissions center, What a joke! She will always fail by a few numbers otherwise, but a fail is a fail.

Ah ok.  I went so far as to count the springs and deduce it was an inline 6 so I thought maybe a Jeep as in Chrysler.    Darn gubment I know.   We have that smog testing in IL also what a stupid time waste.   Yet another thing on ones do-list never mind the fear of and aftermath of a fail.   
My 03 burb got exempted after the last time i took it.  Not sure why something about it being over a certain GVWR.   Weird too cuz its a gas pig 496 engine that pukes smog for added thrust

Minnesota used to do smog testing in the Twin City metro area only. I had a Ford Escort that would only pass if you blocked the hose from the PCV valve to the carburetor. Easy trick. Minnesota finally abandoned the program because air quality was improving and fewer and fewer vehicles were failing as the old carbureted vehicles started to disappear from the highways.

In NYS, all vehicles after 1995, have to be run through “emissions” testing, at the time of the annual vehicle safety inspection. Its based on the onboard vehicle’s computers reading of the engines performance sensor data. Basically if the check engine light is off, the vehicle passes.

There are a couple if wrinkles in that program, for vehicle owners, aftermarket chips and reprogramming of the existing chip, will cause a failure, and that automatically sends an email, to the DMV, which usually results, in a sternly worded letter or a visit from the DMV compliance officer, if there are multiple failures, there could be license issues, fines or at worst vehicle confiscation.

In reality, its a pretty basic and easy system and so far it has worked and we don’t have actual tail pipe testing, at least in the majority of the state, not sure of the major metropolitan areas.

My nephew has run afoul of DMV testing, with his 2016 Camaro, he was running a aftermarket chip and failed the testing 3 times, he got a $650 fine (with court cost) and is subject to random testing for the next 3 years. If he get caught again, its a 9 month suspended license and additional fines.

Post by: firestopper on September 23, 2018, 10:12:46 AM
Before I started crating a vacuum leak and cranking up the idle for a quick pass, It sometime took 4-5 tries. One year I had to run through eight times!
That was it for me. The next year I began to cheat my way through. The rig runs completely like crap for it to pass legitimately.
The whole emissions thing is a scam. The 05 Dmax and 82 FJ have to go every year. Any other rig after 98 can be registered for two years eliminating the yearly testing. $12.25 per car. If you fail, the second test is included. If you fail a third time you pay again etc. Imagine the state makes a shit ton of money. I been considering insuring the 40 through classic car insurance (Hagerty) eliminating the need for emissions altogether. 

1967- present require emissions testing in AZ.
Motorcycles where except some years back.

NYS= emission Nazis, unbelievable.

Nice job Jake   Always wanted a shop press but never got to making or buying one.   I think leaving the Ram removable is a good idea it keeps your options open.  Also the ability to shift left or right could be useful.

First attempt at powder coating.
Could have used a little more powder on the left one I guess.
Pretty neat ho the powder leaves the gun and draws to the grounded part.
Using an old kitchen stove for now, plan to make a bigger propane fired oven eventually

Really should be out cleaning up the yard this morning but decided to shirk responsibility and make progress on my rotab chuck mounting plate. 
The rotab is atypical in that it has a straight 1.000 dia center pilot hole vs a taper.   My plan is to bore the hub and plate in assembly with a mating 1.000 hole to allow use of a 1" dowel pin for alignment and mounting.(https://uploads.tapatalk-cdn.com/20180929/9eb846da7657edd8a656199041e550a7.jpg)

First attempt at powder coating.
Could have used a little more powder on the left one I guess.
Pretty neat ho the powder leaves the gun and draws to the grounded part.
Using an old kitchen stove for now, plan to make a bigger propane fired oven eventually

Looks good.

Maybe, someday I could try powder coating.

Over to the mill for tapped holes and slots.      Having varouos chucks mounted to square plates comes in handy.  Granted its not the utmost in squareness and accuracy but works for me..

Yesterday morning as I arrived to work I noticed a loud metallic rattling sound coming from the engine bay. My first thought was one of those jam nuts on the valve train come loose from the recent valve lash adjustment. I took a stethoscope and pulled the end diaphragm off and stuffed a 3/16" allen wrench and began probing. Well it didn't take long to find the racket comping from the air pump. A relief compared to a loose valve.

So today I decided to pull the smog pump and open it up. We have a great bearing house here in Tucson so the plan was to rebuild the pump.
I was disappointed to find the vein shaft worn beyond tolerance. Sure I could have repaired it but it was just not practical, A-1 Cardone sells a reman pump for $205 plus core.

The first photo shows the pump disassembled, the rear cap towards the top of the photo is the worn shaft. The small needle bearings on the veins (stacked) ride on this shaft. The second photo show all those needle bearings drier than a popcorn fart :P.

Notice the mangled bearing on the pulley end. I'm surprised the shaft didn't seize completely.

The last photo show the new pump installed. Buried beneath the power steering pump. The pump had to be pulled from the top as the lower mounting bracket prevented removal from the bottom. I did have to remove the pulley to get her in. I also replace both fan belts while I was in there.

The other project of the day was to get the ice maker repaired in our kitchen fridge.

I wish the shaft was salvageable, I think the seven bearings would have run $30-40 bucks total.

WOW!

I have a arbor that will handle a 2" wide wheel.  Not sure I want to mount it and use it.  Be good for sharpening things like wood lathe turning tools, gouges, and chisels, plane blades.  Maybe for sharpening large drill bits.
I wound up with a couple of 1" wide wheels that are either 7" or 8" in diameter, I haven't yet tried them.  If you need a arbor for that 2" wide wheel, I have a brand new one here I picked up on eBay several years ago may let go of if I can recover my costs in it.
Title: Re: What Did You Do Today
Post by: ddickey on October 02, 2018, 09:43:16 PM
At this time I have no need for them. In the future hopefully I can get a decent SG but I don't see ever needing a 7" wheel. Not sure if my grinder could take a 2" wheel.
You should see the (2) Norton Diamond Wheels I got. They're used though.
Thanks for the offer though.
If I change my mind I'll let you know.

I may be interested in your duplicate slitting saws if no one else is looking for any, or if you have a few left over later on. I'll be looking to do my semi-annual hike up Barn Bluff real soon, so will probably be over your way in the next week or two anyway.

Looks like I should have built a larger carport.
The drive for the injector pump came loose. Found two broken bolts and two stripped threads. Had to hold the drive gear while removing the drive. Made up three clips that engaged holes in the gear. The broken bolts were about a quarter inch inside the threaded hole. Drilled a 1/8th hole through a bolt then threaded this into the hole to act as a guide. Worked like a charm. The two bolts actually came out with an easy out !!!!!!! Think I could count on one hand how often thats happened for me. Drilled out the stripped holes and threaded 3/8ths course.

On the subject of pressure washers, have a good length of hose, just not as long as that thing. Made up a built in pressure washer a couple of years ago. One of the best things I ever installed. Bought the pump off Ebay and reworked a jacuzzi pump motor to run it. Just spool out the hose and hit the start button.

my pressure washer is a gas John Deere that picked up at a auction for cheaper than could have purchased a cheap one.     But still like long hoses so it has quick connects and have multiple sections of hose so I can reach almost anywhere  I want.   But like your real idea.   
Whoever put that thing there is good I would have to trust them a lot to allow them to do it unless they were ready to pay for any damage.

Wall space is in short order but not as short as tool box space. Looked like a good spot. When I needed big wrenches I'd borrow them from old Tom, one day I said I should buy a set. Tom was a real old grouch, if he didn't like you you'd beter stay away. His answer was what the h*ll for, they're here. Well Tom went and died on me, so I bought a set, why don't they include 1 7/16 in a set. That seams to be the one I most need. Back to a big adjustable.
One day I wandered into Toms garage to catch up on the gossip. Tom says you need that valve grinder out in the shed. What the h*ll do I need that for. Your the only person I know who'd ever use it was his answer. Ended up with a Soius valve grinder and Black and Decker valve seat grinder, with all the guides and probably a hundred stones. Have used the valve seat grinder a few times but the grinder is still collecting dust.
lol He backed that in there like he was parking a Honda civic.
Had a gas pressure washer, it hardly ever got used, by the time I got it dug out, hoses hocked  up and it running I'd loose interest and leave what ever dirty. Then tried a portable electric one, was a little beter but still lost interest before the hoses and it got dug out.
Things now get washed when all I have to do is pull the hose out and hit the button. Did I mention Im lazy.

Greg,
your pressure washer is certainly a convenient set-up. I still have to set up my gas powered and connect hoses. Your wrenches staged over the door are also practical. My set only goes to 1.5" but they take up a complete toolbox drawer and can't be laid-out neatly to fit so when i'm in beed of a particular size I have to hunt hahaha.
One day, I'll have to pick your brain on that PW set-up. Oh! and you are far from lazy hahaha.

I don't consider it lazy, just evaluating effort vs payoff. I'm the same way, and whenever I set something up, the goal is to avoid doing something that will require me to move a ton of stuff, or .. well you get the picture.

I visited one of my favorite surplus (electronic/electrical/mechanical) dealers today and picked up a piece of titanium bar, 2.21" diameter by 13" long. It's marked MIL-T-9047G but no details regarding specific alloy or condition.

The bar weighs just under 8 pounds and I got it for $3 per pound = $24. They thought it was stainless.

I don't know what I'm going to do with it but, that's OK.   ;D

I got the second attempt at plumbing in my rain water tanks actually working today.1x2500 L tank, 1x1200 L tank and 1x1000 L tank.
The first attempt leaked like a sieve from every joint, probably because I was trying to be clever and use silicone as a jointing agent to allow diss-assembly at a later date.
Stupid move.
This time round I used all the correct fitments and the proper cement.
By the time the moment of truth came I was soaked as it had been raining for the last 2 hours (a very unusual circumstance in North Queensland)
As I stood back to admire the plumbing that had no leaks and softly congratulating myself on a job well done and listening to the water tinkling into the tank thinking it will be so nice to have sufficient water to at last water the garden in the upcoming weeks of summer the damn rain stopped.The thin black pipe comes from the 2500 tank and the 2 IBC tanks are plumbed to a manifold then into the black pipe.
This allows each tank to be isolated but also to reach equal levels.
Each IBC has a breather coming from the middle of the tank top reaching up past the top level of the large tank so they can all fill to the brim. (I hope)

I wouldn't put it past California to try and lay claim to rainwater in Australia. Nothing surprises me about the lawmakers in that state. BUT, believe it or not, a quick bit of research shows that it has been legal to capture and store rainwater for personal use from rooftops in California without a permit since 2012.

Some of us are lucky and live in areas where water is plentiful, but in some areas, such as the western states, water is very precious and they have a system of water rights in place. Without water rights you've got nothing. Anyway, some of those states do not allow the capture of rainwater because that rain water would normally run into a stream, and he who has 'right of first use' has the right to every drop of that water. Water rights are bought and sold just like land.

In a similar way, most states also hold all the rights to the minerals in and on the ground, too. That is why you had to 'stake a claim' and then purchase your mineral rights from the state before you could actively mine on a piece of property. If you had no money to purchase your mineral rights, the state would 'stake' you once you registered with the idea that you would pay your mineral rights once you had started to make some money.

Whether dealing with water, minerals, or other resources, the rules vary from state to state, of course.

snip   Why on earth would there be a LAW stating you cannot store rain water...   snip

"Cannot store rain water" would seem strange. Can you reference such a law?

However, requiring a permit might be justified in urban locations. Storing too much water on a roof or upper floor of a building might overload the structure and cause a collapse. Rain water stored in open containers is a breeding ground for mosquitoes. People do all sorts of strange and dangerous things, often with the best of intentions.

Why on earth would there be a LAW stating you cannot store rain water... God's tears!
If I was collecting water to conserve city water and someone told me I wasn't allowed.... I'd tell them to go fly a kite!

In my area, collected water is a breeding ground for mosquitoes which leads to West Nile Virus. That is the only reason that I can think of.

I've heard of these laws, specifically in California and Colorado. I think most of these laws were initially implemented to prevent people from damming/diverting up streams in order to force out people downstream by stopping the water flow to their property. Went back to the cattle baron days of the old west.
How that got to the point of not allowing people to gather and store some rain water is beyond me, never made much sense.
Since the governments of these states now claim all rain water as theirs, I always wondered if it would be possible for someone to charge the state for their rain water falling on their property. LOL
Very similar to the argument about airspace. People tried to stop air travel over their property claiming they owned the airspace straight up above their property. I think the government ruled that it was public domain, but had to throw in a bunch of other junk so people couldn't fly over areas they didn't want them to. The subject is still very heated with the advent of personal drones and if one has the right to fly it over someone else's property without permission.

Made a dumb little adapter thing that I'm sure has a name, and a Starrett number if I could afford an actual Starrett and Noga indicator stand... #lovechina....

I made the slot on the mill using only the dials... THE DIALS... my dro is an igaging piece of horse poop. I can't trust it. Used the dials and NAILED the dimensions I was shooting for. That NEVER happens....
Either way, accomplished exactly what I set out for. My previous mounting method left the indicator quite difficult to maneuver around the lathe, so I avoided using it. I eyeballed until I could use my .0005 dti that did fit in the indicator stand.


Also.... I super glued my fingers together earlier by mistake ...

If one adds several drops of oil on top of the rain water in the barrel, the mosquitos can not break the surface tension to breathe and will die. 
It works if you have  mosquito larvae in a swampy area as well.  One teaspoonful of oil will spread out over a huge area and prevent a big
mosquito hatch.

Nice mallet. It's on my woodworking to-do list. I don't do a lot of gouging or chiseling, but when I do I always want a wooden mallet.

A tip, if I may... When you laminate, whether face or end grain, layer the pieces with opposing grain directions. With opposing vein directions, the piece is stronger and less likely to warp or check. If all the veins run the same direction, it is possible a check or split could run through into the next laminated pieces. Also, boards want to continue to warp or cup in the direction of their grain. If you change the directions, it stabilizes the whole piece.
If it's a table top, for example, if the grains all run in the same direction, the whole table could cup/warp. If they are opposing, as each individual board cups and warps, the next laminated board cups the opposite direction, and so on. At worst, you'll end up with a wavy table top rather than one that can potentially cup and pull away from the skirt or legs.

Been working on the bathroom remodel, finally am complete on the demo. Lot's of unbelievable things uncovered. Contractors can be assholes.  A subfloor that was broken, So throw away that piece, no... put a 2x6 underneath  in the joists. But the problem is they supported the break, and not the other joists. So the crack was supported, but the board didn't support on the 2 surrounding joists... I have to cut out the subfloor and replace it. And that involves removing a wall in the shower... But that wall was never nailed to the ceiling joists, lucky that it had a lowered ceiling that held it in place.  They either used way too many nails, or none at all.  OK RANT over.. until the next time.


Machining:
I started painting the Delta Grinder, and continuing to work on the rebuild. I finally tackled the spindle. After finally getting the wheel center off, I started taking the spindle apart, not complicated but the directions are actually specific, and paint was covering them.  I could not break the nut on the ball bearing end. And was trying to figure out how to hold the spindle to break the nut.. Wait , I'm a machinist (amateur) but capable.. I'll just make a tool to hold the spinde, using the key on the spindle's sheave side.  So just bore a 3/4 inch hole in some steel plate, and then use an end mill to start the key slot to keep it straight.. Then hand file the slot square and done...    ahhh thankfully I didn't forget that I had the ability.. because my first thoughts were clamp the shaft down, or clamp the sheave on the shaft...   Ah, ok, I tried that with a wooden handscrew clamp...

Years back I worked with a guy that was having a home that over looked a golf course. I only metion that to point out it was in a snooty area. He was thinking about a wood shop, all that was there was the frame and studs. Home are built of wood here in GA, Why am I posting this, every wood to wood joint, the builders were using nail guns, they shattered the ends.  I'm not talking one or two here and there, all of them Imagine a.. 2 x 4 with no less that 8 nails in the end.... I could not believe what i saw.

That was in 98, wounder if any of the door or windows close, hope he got the wood shop cause what I saw, he would need it...

In Australia it is illegal to do any plumbing or electrical work unless you are fully licensed for that trade.I often feel those laws were passed not for supposed safety but to protect the jobs of so many sloppy trades people.When I moved into my current home there were soft copper, hard drawn copper, galvanised iron, black iron and plastic water pipes often all types in the same pipe run. There wasnt a straight run anywhere often point to point and sagging between the ends etc etc.Next we had an extension added and when it was being wired up I asked for 4 dual outlets along the lounge wall, well the third degree as to why I wanted so many was pathetic. My answer eventually was "Because its my house"So in they went but the holes drilled through the uprights befor the cladding went on were all over the place making the cable look like a switchback from outlet to outlet.When I queried why it went up and down his answer was "What, dont you think electricity can run up hill"My answer was "Dont be so stupid, I know that anywhere in the western world I do not drill into a wall vertically over a power point, horizontally from a powerpoint and in some countries 45' from a powerpoint. Here I'm stuffed arnt I, that power cable goes all over the place."Just got a hrumph and we never spoke again.This was some years ago now and from what I have seen nothing much has changed.Had a plumber plumb in a downstair toilet.This idiot placed a soldered joint in the middle of the brick wall. Yep, it sprung a leak at 1am the next day.When I called and woke him up he told me to turn off the water and he would be round in the afternoon.My answer to that was "I havnt paid the bill yet so you better get round now" So he did.

All carpenters use pneumatic nail guns. The only framing that's hand smashed now are trusses and some old school guys doing the back framing (bulk heads, dripped ceilings, builder finished basements, etc)
8 nails in a stud is highly unusual and rather irresponsible. Sounds like that wall got taken apart and rebuilt a few times. 2 in a 2x4 and 3 in a 2x6 is all that's necessary. The strip nails have a glue coating on them. They grab surprisingly well. Very strong. The framers have been shooting nails since the late 80's.

It is illegal to work any compulsory trade without a license and a permit. There's two reasons, safety, and the government wants their license money. They say it's so they can perpetuate jobs, but at the same time make it very difficult and expensive to break into a trade.

There are still a lot of old school tradies and are very disgruntled. You even look in their direction and they lose it. Heaven help you if you push him out of usual tasks. That generation is quickly retiring (read: dying off. None of them were smart enough to put money away and wind up smoking till they die.

Most all of my nailed ends are split. Some tremendously... Some blocking just blew apart. I use a nail gun for woodworking, not necessarily for furniture making, but for building jigs.. The advantage of the nail gun is less split wood. The dull points don't split by wedging the wood. But framing nails still have points. Which I find interesting, because in the old days I watched a framer take a bunch of nails and he prepped them by hammering the pointed end .. I asked  him what he was doing and said if he takes the point off it lessens the split wood.  The 2 of us hanging out watching were sure he was pulling our legs, but later in life I found that it was true.  Wonder why they don't do that with framing nails, but do on finish nails.

Most of our framing lumber we get down here is yellow pine. That stuff is so loose grain and wet that you don't have to worry about splitting. It's after 40 years you go back in and try to place nails in some of this wood. Oh, we can get fir down here, when the local independent lumber yard has it on hand, very pricey!

Spruce is coniferous evergreen. Basicly a pine tree.
 Back during the building boom of the early 2000s when I ran a framing crew we went through so many 2x4s they started importing it from Germany. I used to get bunks of it right off the boat. I asked the salesman how can this be cost effective? He told me that the after we boomed the snot out of Germany during WW2 the US helped replant the forest we destroyed.
 All of it was stamped {SPF} Spruce Pine Fir.
 True Southern Yellow Pine is used for roof trusses and beams here in Florida.

i cant even buy prime SPF lumber anymore, and the select and better is god awful. most building supply stores send me lumber that is soaking wet and black with mold. i can go buy from home depot but the sticks are pretzels. the prime lumber is used for pressure treated. its at least straight, albeit, still soaking wet.

its not very often we build a deck and have the opportunity to go back and see it a year or two later. this past year we did two interior jobs we had previously done decks at. i was shocked at the state of the lumber after a year. we wound up replacing a bunch of deck boards and railings because of how badly the boards cupped or twisted. by habit, we always install cups down and crowns up with the mind set that the cups and crowns will flatten out. in both cases the cups had inverted, and the crowns just twisted like a rope. and dont get me wrong, i fasten the lumber in such a way to help prevent the twist. but the soaking wet wood unevenly drying in the sun is a force you just cant contain... then the outdoor jobs start to look good from far, but far from good. not a great way to make a name for yourself...

Got a ittle shop time this afternoon before our Thanksgiving road trip to the relatives.   
Last pc of the rotab adapter I’ve been slooowly making.    Next will be some TIG welding all the pcs together.   I designed it with my crappy welding skills in mind such that the joints will all be simple, tight fit up and easy to access.   And of course non critical as far as strength and penetration.   I’ll post pics of the that process good or bad.   For now another “boring” lathe pic

(https://uploads.tapatalk-cdn.com/20181121/6a7eb8c8a77e7bf15e7eb1b993297171.jpg)

The blue highlighted lines are where my  welded joints are.   All fusion no filler rod I can’t walk and chew gum yet. 
Typically I would chamfer the joints but I dunno what you guys think?

On a joint like that I'd chamfer it and fill. With my poor skills I'd never get deep enough penetration with a fussed joint.

Chamfer and fill, for sure. You'll get a much stronger weld for one thing. You more or less said yourself that you need more practice, so here's a good opportunity.
Title: Re: What Did You Do Today
Post by: firestopper on November 29, 2018, 08:11:41 PM
A slight chamfer will allow for more filler rod, but really not necessary as TIG is pretty hot by comparison to other methods.
I bet a simple penetration (autogenous) bead would hold up great and like awesome.

Ok I took a stab at TIG welding up my parts today.  Degreased everything and made up a goober head type rig for a weld positioner using my rotab and a cordless drill.   Pc of #6 wire for a slip ring ground.   
No practice just hit it and go.   
Modulating the drill while one handing the torch was a bit iffy.   Not pretty as I suspected would be the case but it should be plenty strong.    Heres the results pre clean up.

Post by: PJB on December 15, 2018, 04:13:43 PM
haha I only showed the best section there.  Looking at it does appear like I put way too much heat in it.   Welder was at 80A, 25cfh argon.  1/16 thoriated tungsten.  not sure how fast I was turning but I tried to keep it moving steady as the puddle formed.  Had several flare ups blind me as I wavered the torch height possibly interupted argon flow or something.  I will say having a foot pedal to control amperage and high frequency arc start like we have at work would be very nice.  I only have the basic lift arc start on mine so it is a bit violent starting the arc and getting settled in traversing.

I only have scratch start. When I rigged it all up and started playing with tig all my welds were gray. I heard something on YouTube a few weeks ago saying a gray weld could signify too much heat.

There are sooo many aspects of tig welding it was hard to focus on every one and test them with the limited material I had to practice on.
Title: Re: What Did You Do Today
Post by: Terrywerm on December 16, 2018, 09:59:07 AM
No welding here but I spend some time last night doing what I thought was going to be impossible: unplugging the dip tube in a gas tank on a small 20 HP tractor that sat unused for the last three years. Instead of a bottom fuel tank outlet, this tank has a top draw on it with the tube sticking out the front of the tank. It is designed for 1/4" fuel line, so the tube's ID is not very large either.  I tried compressed air, trying to blow out the plug of varnished gasoline, but no luck.

Next I tried a piece of 14 ga. insulated copper wire. I worked it down the tube which has two bends in it. The tube is horizontal where it comes out of the tank. It passes through the front wall then makes a bend and goes vertically to the bottom of the tank where the second bend makes the tube horizontal again for about an inch before the tube ends. I could get the wire to a point just past the second bend, but it stopped firmly at that point. I tried working it back and forth with no success there.

I decided that I would need some chemical assistance and settled on giving a little bit of acetone a try. Using a small funnel and a short piece of fuel line I was able to get just a little bit of acetone into the line. I then started with the wire again, primarily to make sure that the acetone got all the way to the plug without an air bubble blocking things up. I started working the wire back and forth, making no progress on the plug even though the wire was full of brown crap when I would withdraw it.

Acetone may not be the best thing to add to the fuel, but I figure that there was roughly a teaspoon full of it now added to the tank. It is a small enough quantity mixed in with about 3 gallons of gasoline that I don't think it will cause any other problems.

I tried turning the wire with a drill, but it simply twisted up on itself and got me nowhere. But I liked the Roto Rooter idea and saw it as the best and possibly the only way to remove the plug. I happened to have some old bicycle parts of my dad's here, so I scrounged through them looking for an old brake or shifter cable (my dad kept everything) and sure enough there was one in the box. I removed the cable from its sheath and cut an appropriate length. It slid easily down the draw tube but stopped abruptly at the plug. I applied the electric drill and started working on it, and this showed some promise as the acetone level was dropping in the bottom of the funnel the further I went. I found out that turning the cable too fast resulted in it twisting up on itself, requiring replacement of the cable, but turning it slowly showed the most promise. After about 20 minutes of messing around I finally broke through.

I reinstalled all the fuel lines and gave her a start, she popped off right away. Thankfully the carburetor wasn't plugged up too!

More to do to get this tractor ready to make the trip to its new owner, an old friend of mine. He bought a place out of town and he asked if I would be interested in selling it. After some thought, I figured why not. I could use the money and the space more than anything right now.

next time pick up seafoam, my neighbors  crapsman snow blower doesn't have a fuel shutoff and he left the tank full. Couldn't get fuel thought it last year, after much work, he took out some seafoam, and by the morning all clear.  I couldn't believe it, but am a believer now.

Good to see you got thru.  i was waiting to read the part where the cooper wire broke off after the bend!.  Never fails in those kind of projects.  The acetone wont hurt your fuel any.  Granted your issue is already solved but actually naphtha would work too as a solvent and its one of the main ingredients in many fuel additives. 
I used to use seafoam in my boat fuel for winter storage until I discovered it contains roughly 20% isopropyl.   I go out of my way to fill up with non-ethanol laced fuel at winterization so no way I want to intentionally add a water sponge sucking ambient moisture into the fuel all winter.   For cars driven regularly sure its great to absorb any water, and clean fuel system.   I digress.
Finishe welding the other half today.   Pretty colors.   Its good and glued.   Put the TIG away for another 6 months

I have used Seafoam in the past, it always seems to be good for whatever is wrong in a gasoline fuel system. I picked some up this morning and added it to the tank, figuring it certainly cannot hurt. I then ran the engine for a bit to warm up the motor oil so I could change the oil and filter. Just like last night, the engine popped right off without even choking it, which seemed really odd. I decided to leave the carburetor adjustments alone, figuring that the Seafoam might just straighten things out after a while. After completing the oil change I had the engine running once more as I was moving some things around in the garage. The tractor was happily idling away when suddenly it started to misfire, made a couple of pops and died. Had to choke it to restart it and keep a little bit of choke applied to keep it running. If I run it some more maybe the rest of it will straighten out too, given a little time.

I used my tool post grinder for the second time ever yesterday. OD this time. I made a live center that I wanted to grind the point accurately. Ended up probably ruining the center, it's still there but a fish tail leads me to believe it is no longer at 60°.
Awkward. Not a fan of it. Probably would be good for straight ID or OD but angles, IDK.

Made this thingy...
That's a thermocouple sticking out the front. I am building a steam shower at work. The sleeve/bushing it came with is only 3/8" long threaded with a nut.... the tile I'm using is 3/8" thick... plus mud, plus drywall... you see the problem...

Made this unit from stainless, threaded 1/2-20 with a brass nut and just an off the shelf washer. Only the head and the probe protrudes through the tile. The rest is behind the drywall.


PS. I also figured out my photo resizing issues. Photos shouldn't take up the whole page and then some if opened...
Title: Re: What Did You Do Today
Post by: woodchucker on December 18, 2018, 10:12:09 PM
No to the steel washer.. Use either stainless or brass. Also use some anti corrosive goop (electrical dept) for the threads. You are using disimilar metals, and steam and 5volt power. That's probably enough to cause metal to metal corrosion... I'm not even sure, but I know when doing my pool they required some stuff to prevent the dissimilar metals from oxidizing and corroding.
Title: Re: What Did You Do Today
Post by: Carpenter84 on December 19, 2018, 12:13:28 AM
I hear ya. But if I wind up with moisture on the washer, I have much bigger problems than corrosion. Means I have a leak. The shoulder and shank will be siliconed in the hole. I have gone to great lengths to make sure moisture and heat do not escape this shower. Most of the rough side of the shower is spray foamed. To try and encapsulate the shower to make sure I don't wind up with a condensation issue.

The washers only job is to make sure the brass nut does not bust through the drywall.
Title: Re: What Did You Do Today
Post by: Carpenter84 on December 19, 2018, 12:18:21 AM
The whole shower is waterproofed with kerdi paper, spray foamed all in the stud space with the exception of one wall (where the pipes and cables pass for the shower) all surfaces are tiled/stoned to allow water to cascade onto her next surface and not into a crack/gap. I have my shower builds down to a science.

So for a few pennies, you're not willing to replace the washer. Gain a bit of insurance and removing a possible point of failure down the road?

 Hell you went to the trouble of making the part fit the application, why not follow thru with a washer swap?

No, I was not going to bother going and finding one stainless washer to fit this specific application as this area will not see moisture, but if I'm gonna get grief for it, I will make the effort.

Post by: chips and more on December 21, 2018, 04:00:55 PM
I was not sure. Was thinking maybe 50/50 chance of breaking the broach. Was thinking maybe I should use my Bridgeport as a slotter? Oh well, I went for it. It was no problem! The steel was 1144 and about 1” long so about three teeth were cutting at once. That concerned me, thought maybe too much tool pressure. I was wrong. And in the end everything was better than expected. No warpage that I can detect. I bored and lapped the hole at the start to within 0.0001”. And thinking that was a waste of time. The things going to wrap after I cut the gear teeth and or when I put in the keyway, well, no warping, I’m happy.

Taking a break from the steam engine.
A couple of us are fixing up an old ice fishing shack. Won't be a safe fish in the lake.
Anyway, needed a wood stove, so built one today. Had some pipe, 12 3/4 od with a 1/4 inch wall, shouldn't burn through any time soon. Some REALLY rusty plate made up the rest. So rusty the plasma table had trouble with it, the pitted surface kept deflecting the arc resulting in a rough cut,
Attempted to brush the dust off my rusty stick welding skills, the metal was far to rusty for mig without hours of grinding. Can't remember the last time I had the old Miller stick machine going. Forgot how nice it was to weld with, think its 250 amp DC, the rod just never sticks with that much power behind it.

Saw this idea this morning from BGHansen (Bruce) and just had to copy it.
It is such a simple answer to what was for me an infuriating problem, getting the oiler spout to seal up against the ball oiler without spurting oil all over the place.
It works a treat and really delivers oil under pressure through the hole.
Bruce has a small "V" notch in the end of his but I found by making sure the ball isnt pressed all the way down allows the oil pressure to push it the rest of the way with no problems. The "O" ring is held in place with a tiny groove so it sits proud of the end.

You gotta remember, cats figure that THEY are in charge and the rest of us are here just to serve them.  ;D

Yesterday I sent an old 'friend' on to a new chapter in its life. Built in 1973, it was a Simplicity 4041 'Pow'r Max' tractor. It's first owner was the Belle Plaine Minnesota high school where it mowed the lawn until I purchased it in 1988. It came with a 60" mower deck and a three point hitch on the rear. We were living out of town and had quite a bit of lawn to mow as well as snow to move, so it was a logical purchase. I quickly built a front dozer blade for it to move snow, and a grader blade for keeping the driveway in shape during the warmer months. Next came a one bottom plow made from a John Deere 14" plow bottom and a cultivator so that we could put in a nice sized garden. Then I stumbled on a sickle mower for a Farmall Cub for free, which I modified to fit on my tractor. I made some money for a few years cutting weeds for people in the area. Then the Halloween Blizzard of 1991 hit and I found that the dozer blade just wasn't enough for moving three feet of heavy, wet snow. So, I started planning for building a two stage snowblower, 58" wide and 32" tall, which I built over the course of a year or so. It worked great, and anytime we had a big storm I ended up doing every driveway on our block.

Since we now live in town, I don't often have use for the tractor, so it was sitting for long periods of time. I inherited my dad's 26" snowblower a couple of years ago and found it so much easier to use for most snowfalls. I did a total rebuild of the engine in 1996, with .020" oversize pistons and rings, all new valves, new bearings, and new camshaft. The tractor now sees so little use that it only has 120 hours on the rebuild.

So, after 15 years at it's original home, and 30 years in my possession, I hauled it 150 miles to its new home yesterday. A fellow that I grew up with and have remained more like brothers with over the years bought a place in the country out near the South Dakota border where the wind never stops blowing and the snow is always drifting. He has a four wheeler with a small blade on the front but soon realized that he would need something a little bit more serious for the bigger snows and asked if I would consider selling my tractor and implements. A deal was struck, and I delivered the tractor with the snowblower, dozer blade, grader blade, plow, cultivator and mower deck to him yesterday. Thankfully I was able to borrow a 35' gooseneck trailer from another good friend. I need to do some repair work to the sickle mower before it makes the trip, but that will give us a good reason to go out for a weekend visit in the spring.

Today i am working on a simple curved spacer to be able to stick one of those magnetic cell phone mounts to my wifes car dash.   Zero flat surfaces anywhere and she wants it in a specific spot.   Made several full scale profile templates varying the radius dimensions until it matched the dash curvature.  Making it out of 1.5 dia aluminum.
Thickness tbd so as to stand proud of the round vents.

I will surface the curved part on the Tormach then face to length as needed.
Using some 3m vhb tape to stick it all together.
$5 mag mount + all day screwing around making a spacer but hey this is why we have machines and tools.   To make our wifes happy???!🤣

Its one of those inexpensive 3” chinese 5c collet mount chucks.   Took the 5c end off and mounted it to a square plate.   Good for doing round stocks projects.   Mounts on my rotab as well or even bolt directly to the table.   Using the vise is much more convenient tho.   The Tormach vise i have to remove the jaws to fit the plate in. I started making the mounting plates for all my extra chucks.

I might do that to a Asian made chuck, not my Cushman chuck.  IT's from a dumpster dive, was mounted on a 12" rotary table and probably used one time for a job and sat there until it was thrown out.  It's in very nice shape!  IT's never been on a lathe either

Next up and for no particular reason other than why not- I decided to try to make some custom grip sets for my 1911
For now Im using leftover aluminum from another job and a fairly plain Jane design.  Once I have a process and work holding worked out I can expand the design and try different materials.   
Played around with the CAM a little today but it’s premature until I figure out how to do the actual work holding.   I may start with drilling the holes and use them subsequently to mount for surfacing.  Anyone here done these before and have any advice as to methodology?   
(Other than ya the I know grips are sold all over the net for really cheap!)

The plan right now is to make a fixture block out of aluminum that will clamp in the vise.  The block will have (2) #10-32 tapped holes on the top edge corresponding to the grip hole locations.  Screw heads are a tight fit diameter wise to locate the blank securely and also sit below the finished surface.  This will allow me to machine all the way down and around the curved side without hitting the vise jaws or milling into a spoil board.  I started facing the block and made some custom low profile fixing screws out of flat head socket screws this morning.

Title: I Avoided Using The Rotary Table Again!
Post by: chips and more on January 01, 2019, 07:04:55 PM
Today I needed a radius end on my project. The part had a post and some holes. And as some know, I hate the rotary table. I always use this approach but not with the indexer. I went outside the box and took advantage of the post and holes my part had. Used my indexer as a bearing and holder for the part.

I’m not recommending this method! Only for entertainment! You can get into serious trouble doing it this way, even for a seasoned machinist!

I have several of the pictured handle. I repurpose them from old car jacks. They make good BMW specialty tools. But this time it was for my project. I just put two threaded holes in it…done.

I never climb mill. Only on a finish clean-up pass! I use a small end mill and the more the flutes the better.

Taking light cuts and using the handle to feed the part. It didn’t take but a few minutes to make the radius end.

A few advantages are radius alignment. And not dealing with a heavy and set-up time of the RT…Dave

I don't think we have a "what did you buy" thread, so, this is a good a place as any.

I've been bad lately and have been spending money.

I bought an angle block set because there has been a few times I've needed a 45 in the vise and my V blocks were just too big for the part in the vise. The boy was counting them for me...

And this mitutoyo depth mic set I'm quite pleased with. $130.

Well, the reality is that I cannot claim this photo as my own since I was not even born yet when it was taken. My parents were still 18 months from their wedding and I would not come along until 11 months after that.


No, my part in this is one of preservation. The photo was taken as a 35mm slide in January of 1957 by my dad. The young boy is his youngest brother, my uncle Ed, who is only nine years my senior. He went on to serve in Vietnam and is currently enjoying retirement and spending lots of time with his grandchildren. The photo should give him a story that he can tell them.


This is a thread about what I did, and no, it wasn't machine shop related, but it is a rather daunting activity. My dad was an avid photographer and took about 8000 sllde photos between 1957 and 1990. After that he switched to print film and took Lord knows how many photos since then. I am currently working on scanning first the slides and then the prints so that the entire collection will be in digital format. Scanning goes fast, I did the first 1200 slides in about six hours. The time consuming part is cataloging them and "fixing" the ones that have deteriorated over the years. It is is amazing what you can do with modern photo editing software.


The photo in question was done by moving my grandmother's dining room table over against the wall, then opening it in the middle as though to add another leaf. My uncle then sat on a stool under the table with his head sticking up through the opening while some linoleum flooring scraps and newspaper were strategically placed around his head. A piece of scrap baseboard was placed against the wall and a chair was placed on the table off to one side. Finally, good old tomato ketchup was used for effect, Ed closed his eyes, and the shutter was released.


So, I saved this and many other photos for the enjoyment of family members. I wasn't making chips, but I think it was time that was very well spent.

 Not shop related but garage..
I hate all the salt and muddy slush in the garage brought in on the cars after snow storms.  It melts then we and the dogs walk thru it. Comes in the house and trashes the door rugs. Yuk. 
Normally I would grab the hose and go to it but thats obviously not a good idea in freezing weather. 
My little hack is to shovel in a bunch of clean snow.  Then i work it around with a stiff bristled push broom.   Kind of like natures floor sweep compound.  It picks up most of the crap and I sweep/shovel it out.
Good enough for February!!

Its an old Hardinge Shawn, about the same age as me, and thats getting old. Most of the ones you see are HLV-H this is the predecessor an HLV Picked it up on Crown Assets a few years ago, needed a lot of attention but came with 3 and 4 jaw chucks, good set of collets, follow rest steady rest and taper attachment. Had to make the gear that drives the carriage, replace the belts, it had sat so long the belts cracked where they were bent over the pulleys. The lube had dried out on all the gears and bearings, had to tear it totally apart. While I had it apart it got a coat of automotive urethane, has stood up pretty well.
They're incredible to thread with, you set a carriage stop and thread at 5 or 600 rpm tight to a shoulder. They used a massive two speed motor that only develops about 1 HP if I remember right, but they were precision balanced runs almost silent. Apparently to help stop harmonics they drove the carriage with a separate DC motor for regular turning.
They don't have much jam for heavy metal removal but thats not what they were made for. The Summit does that.

Jeez, it's beautiful.
I see a lot of hardinge lathes for sale online around here, actually. They come up almost more than anything else. A lot of turret lathes. But they're very expensive... 3k minimum usually.
Title: Re: What Did You Do Today
Post by: 4GSR on February 13, 2019, 10:20:48 AM
3K is not a bad price if it like the one FC350ca has.  His is one of the fully equipped ones that usually sell for much more.  You have to be careful at what you are looking at, thee are bare bones ones that don't have all the fancy stuff as his has, all the way up to very fully equipped ones like the one FC350ca has and more.  A good place to look for information on thsese is look at Tonys website over in the UK.  I bet FC350ca can help too.

Lol. It's way out of my price range.

And yes, many of the ones here look very bare. No tailstock, often no turret, no tooling, no collets, maaaaaybe a tool holder on the cross slide.

Here's a decent one a couple hours away.

Title: Re: What Did You Do Today
Post by: 4GSR on February 13, 2019, 07:29:51 PM
One other thing to remember about the Hardinge lathes, the DV-59 series have two speed motors.  Got to make sure you get one with a 220V motor unless you have 440 or 575 volt current coming to your house. 
Title: Re: What Did You Do Today
Post by: f350ca on February 13, 2019, 07:37:26 PM
The HLV's use probably the same two speed motor. You can use a transformer to step up to 440 but they aren't cheap.

Didn't do it today but thought about it.
Was going to change the oil in my compressor, a big old cast iron V-4 two stage. Checked the oil and it looks like the day it went in. Does oil wear out? There's no products of combustion like in an engine, to clutch material like an automatic transmission, no material off the synchro's in a standard or material off running gears, so does it really need changed?

Post by: Terrywerm on February 20, 2019, 02:00:21 PM

Compressor oil typically just gets contaminated with metal particles and moisture, moisture being the greater of the two evils. I used to change mine every two years, but now I change it every year simply because it's easier to remember whether I did it or not.

Drove over to the Skidoo dealer to get carbide ski runners and oil for the machine, Cardon tools is close by so stopped in, they sell some used but a lot of new old stock. They were having a sale.
Ended up with NOS Moore and Wright dial calliper, .0005 dial indicator, and a 2 inch travel one. Along with a couple of 1/2 inch carbide end mills, a set of very lightly used parallels, (mine are getting badly used) and a wheel for the surface grinder. Can anyone figure out the grit, this one says 60 but they had some marked 46 that were a lot finer? And a set of 1-2-3 mag blocks for the grinder. They're a lot finer poled than my chuck and as hoped seem to hold small washers beter than the bare chuck

Nice haul. I need to get some mag 123 blocks. And V blocks.

So, what’s the purple wheel for?

I’ve been liking the Moore and Wright 0-1, 1-2, 2-3 mics I bought recently. Opened my eyes a bit to different brands other than the overwhelming desire for starrett.

I made a test indicator holder for my Mitutoyo that didn't come with one.


I like using an indicol that I modified with a longer screw for my 8520.
And it requires a dovetail or small shaft. Well the Mit, shaft is 3/8.. so no go there. And the existing snug just wasn't working for this.
So:

See the whole thing here: https://imgur.com/a/VWiL57B (https://imgur.com/a/VWiL57B)


I actually fixed a mistake I made. I had not realized when using the DRO which side of 0 I was on, and move it too far. So I plugged the hole with a 6061 dowel, peened over the aluminum. You can't tell on the dovetail side, but you can where I had put a chamfer on the indicator side. After it was nicely tight I milled it flat again.
Not bad, saved me from starting from scratch for the 3rd time.

it's pink , like white it has friable particles. it uncovers new grit as it's grinding, so it cuts nice and doesn't burn like grey, or silicon ..

That's the wheel you need on your SG. ;D  That's a ceramic/aluminum oxide based wheel. 

Good question about the grit of the wheel.

Shawn I need to resurface the magnet on my surface grinder. Hoping this will handle the task.
Jeff I thought it might act that way, the grit numbers on them made no sense as I said but hope its a J for hardness. If I understand correctly you should use a harder wheel on a soft material, which I think the magnet is.

White wheels are mainly for sharpening the cutting edges of an cutting tool.  It's grinding a small area at the tip of the grinding wheel.  The ceramic purple wheel the fc350ca bought is for surface grinding, mainly soft to medium hardness materials.  And it still can be use for quick grinding of harden steels.  Probably do good on grinding harden steels IMO.

Huh... so, it’s settled... I need a purple wheel. And one with a 2” center. I have two 2” arbors (Think they’re 2”. Have to check) that have balance weights. The 1 1/2” center wheels I have the arbor has no balancing. And I can see out of balance evidence in my grinds.
Title: Re: What Did You Do Today
Post by: 4GSR on March 02, 2019, 11:11:54 PM
Wheels and arbors should be 1.250"  The hubs for SG should be 3" OD.  2" OD hubs, I bet they are 2.250", are for smaller wheels and for T & C grinders.  They work on SG's just don't offer much stability in a wheel for surface grinding.
Title: Re: What Did You Do Today
Post by: Carpenter84 on March 02, 2019, 11:52:33 PM
On closer inspection, these are loafers... Sorry, wrong tvshow.

The hubs I spoke of, in fact, don't fit the arbor on my grinder. Shame... Cause they're good looking hubs. So, no idea what these hubs are for then. Again, shame, they came with a balancing shaft.

So, how does one balance a 1 1/4" wheel?

Edit... Sideways photo, sorry... The small hub on top in the center is the 1.250" from my grinder. It came with two hubs, but only one lock nut. I said I'd make another set one day, still haven't.
Title: Re: What Did You Do Today
Post by: 4GSR on March 03, 2019, 09:32:22 AM
Grinding wheels made today are more balanced than they used to be many years ago.  Mount your wheel as you normally would do.  Be sure you put the "blotters" between the wheel and the flanges and gently tighten the nut.   Dress the OD of the wheel with a diamond and that should be all you need to do.  If you're getting vibration, it's probably is from belts and pulleys.  The other thing you can do after dressing the OD of the wheel, dress the sides of the wheel. 
If the wheel adapter has weights, yes, move the weights around until you get the wheel balanced.  Or just pull the weights and discard.  I personally have not used the weights to balance a wheel.  The few adapters I have that uses weights, I either removed the weights or they never came with them.  I've bought all of mine used.
Title: Re: What Did You Do Today
Post by: Carpenter84 on March 03, 2019, 11:27:54 AM
I'll try to look for markings on those hubs. They're obviously not for this grinder.
I really should make another nut set. The grinder came with two tapered arbors, but only one nut set. The guy threw in the other larger hubs not knowing what they were for.

What I did this evening was model up in CAD and start setting up the cnc mill for a job that came in over the weekend.  Making 5 nylon parts that are all the same basic shape but the diameter changes slightly on each one.   Normally I cut round stuff in the lathe (shocking) but in this case I decided to make via circular interpolation on the mill.   The nylon chips fly off the mill nicely as opposed to the stringy birds nest when done on the lathe and I dislike cranking the compound to machine angles.   Plus my CAM package automatically updates the path when I update the CAD model so after the first one its change one diameter in the model, update path and roll...
Going to mill the side with the small shaft first then flip in the chuck and do the other side.   Concentricity is not super critical for the customers application so I can get away with it.

The belt in my lathe has long been problematic. It's worn out, starting to delaminate, and it's clunky. I debated pulling the spindle to replace but just about everyone and their uncle had bad news for that job. So I've been meaning to try link belts. I finally bit the bullet and ordered some since I've been fabricating so much lately. Gosh darn expensive stuff... $75 for 5' was the cheapest I found. Amazon. Cheaper than local.

It's 1/16" wider than an A belt, which is strange, but it must thin out as it stretches. Which it's done lots of so far after 10 mins of dry running. I've already removed 2 links to compensate.
I left the old belt in off to the side until I was confident it'll work.... My god I hope I don't regret cutting the old belt out...
Title: Re: What Did You Do Today
Post by: f350ca on March 10, 2019, 02:29:32 PM
I found 10 or 12 feet of it (new) at the dump. A little different design, it uses rivets to hold the sections.  The belts went on my General table saw (cheap belts only lasted about 20 years. Tried the link belt on it, fit the same, high in the pulleys. The saw seamed to run quieter but could not get them tight enough to not slip. Probably not a fair chance, the belts are short and the pulleys are only a couple of inches in dia. Ended up using it on the shaper, big pulleys and long belts, seams to work fine there.

Title: Re: What Did You Do Today
Post by: Carpenter84 on March 10, 2019, 03:29:10 PM
I also noticed I really had to crank up the belt tension. Anywhere less, more in my comfortable belt tension zone, I could stall the spindle.
I don't like the higher tension. Putting a lot more force on the various bearings. It's also making the motor run about 300mA higher than previously. Which doesn't seem like much, but when the current only sits about 400mA below the over-current setting in the VFD when taking a semi heavy cut normally, there's not a lot of headroom there. I haven't much choice now tho... It's on there. The old belt was cut off. I haven't actually used the lathe yet with the new belt. It is quieter, no more clunking and belt noise tho.
Time will tell.

The cost of that belting is ridiculous, what a rip-off! As for my 3 cents on the use of link belting. Sorry, can’t give too much. I did use some the rivet kind a while back. It did the job and I don’t recall any severe stretching.

Interesting...

Either way. I learned. Hopefully it's not a mistake. I have read into it a bit and for woodworking purposes people seem to like them. Initial cost is quite extreme - which has been my hesitation. I think the forces on the belt are quite a bit higher with metal working over woodworking. So, hopefully I don't have any slipping issues. If it slips, I may consider using a flap wheel and trying to narrow the belt a bit, say, with the machine running real slow, to see if the belt will sit down in the pulleys a bit better. I have to imagine the slip is due to so little surface contact. The belt is really only in the groove by 1/8" at best. That's kinda silly...

Title: Re: What Did You Do Today
Post by: Carpenter84 on March 11, 2019, 04:08:03 PM
Yes (ken), no (Dave).

I have a can of belt dressing and I'll use it as a last resort. I don't like how it gums up, and I'm sure it wouldn't do much good with the amount of oil that flies around in there. I try to keep the bushings and bearings well oiled. There is an oiler in the spindle pulley, but it's damaged and not worth a crap. I need to figure out how to extract it. I have new button Oilers, but they're imperial, old are metric. I have a reamer I'd been using as I slowly replace them.

The A belt that was on there fit fine. The new link belt is 9/16" wide.

No, it's not an oil splash, but it's definitely been splashed with oil.... In reality, I'd be totally fine if someone came and closed in the one small rear section that is open and I made it an oil splash...

I’ve used Fenner Power-Flex segmented v-belts, as the sole type of v-belt in the shop for almost 20 years. I also used the Harbor Freight sourced v-belt, thats made in Italy, on the new (to me) Rockwell milling machine.

The company I worked for, used the Fenner for all of their belt use, as a HVAC contractor, they gave everyone 3 large boxes of belts (3/8”, 1/2” and 5/8”), they completely stopped buying individually sized belts, and are still doing it 25+ years later.

I have never had a bearing or sheave (pulley) issue, due to use of higher tensions, excessive belt wear or other wear or mechanical issues.

I bought one 3/6" wide to use on my KO Lee motorized work head.  I can grab it and make it slip, but in operation I've never had it to slip.  Seems like when it it running, it "grabs" better than when idle.

Shawn, that belt at 9/16 wide sure doesn't sound right for an A-section belt.

Two good thoughts, the correct belt to fit down in the V or belt dressing. For the price of a belt dressing it's worth playing with.  I did not see or missed the aprox age of the one running now, just curious.

Found CRC belt dressing and grip, use it on my compressor. Lives outside in the weather, protected from the rain. Powered 24 x 7 385, not that it's used everyday, but when I want air I want it now.  lol

Why did I use the dressing, the compressor was squealing at start up, once it ran some quiet. Thought I noticed it taking a bit longer to recover at first. The noise came later, now think it is a bearing, dowel and ear tool could not locate the sound when probing the pump and motor. That is when I decided it was the belt

 Belts dry out the CRC is applied to the sides of the belt.

I captured this as I thought as to how you might id the proper belt, it is a Canada granger page, so LOL  it is written in Canadian ...... I'm so funny I just kill myself sometimes.

https://www.acklandsgrainger.com/category/V-Belt-Pulleys/Sheaves-and-Pulleys/c/5260

Back to the image, notice fourth line down regarding the V beltS V.

It is likely can pull up the V belt pulley page and find the pulley on the machine, and  the belt to match. 

I have some experience with this, because I took a delta wood bandsaw and turned it into a metal cutter. Changing the drive pulley and adding the proper belt.

Spent the afternoon (home early from work) making a chip guard for the lathe. With all the turning I've been doing lately with the grinder, the garage is a war zone, with chips EVERYWHERE... And the lathe is the worst. That big aluminum wheel has been the worst.

.080" sheet of lexan. Heated in the oven and curved over a form. The trim is some kind of aluminum trim/edging I found at Depot. The assembly slides around on that shaft. Can move a reasonable distance back and forth to accomodate most of my turning. I'm not generally more than 10" away from the spindle nose. I made a locking collar stopper that can be adjusted. The whole thing can flip up or down onto the stopper.
Yes, the lexan is cracked in numerous areas... It's really difficult stuff to work with. And drilling is a challenge. I have a plastics drill bit, but punching through has to be done super gingerly. And I cracked it a bunch of times. I have over half of the sheet left. I can just drill out the rivits and try again if it cracks more and becomes crappy. Depot also had a plexiglass polish/cleaner I grabbed. Supposed to be able to clean and keep the surface scratches to a dull roar... Hopefully this keeps the flying chips at bay and out of my face.

I usually scoffed at the lathes with the guards with the built in interlocks, but I definitely see the worth in the guard.
Title: Re: What Did You Do Today
Post by: PJB on March 14, 2019, 04:12:26 PM
That looks pretty nice
I also generally dislike guards on machine tools but in the case of flying chips on the lathe they are well worth the occasional access hinderance provided its easily moved out of the way which it looks like it is.
My issue tends to be the tool post lever hitting the edge of the guard when traversing towards the headstock.    I just lift up the guard slightly as the lever approaches then it rides on top.   No biggie but i have crashed into it once or twice.   Fortunately mine is kind of flexible so it just twisted a bit .  Clocking the lever so it’s parallel when locked might be a solution.   
Title: Re: What Did You Do Today
Post by: Carpenter84 on March 14, 2019, 04:41:41 PM
I had the exact concern. Ideally I would like the guard lower, but the tool post arm gets in the way. Which was why I made it all adjustable. The guard stops just above the tool arm. I was even pondering ways to not have the tool post arm right there. My current thought is to put a bend in the arm to lower it slightly, maybe.

Could always unscrew the TP lever assuming you plan to use a particular tool and not need to change out frequently.    Not the most elegant solution.   Defeats some of the quick in quick change.(https://uploads.tapatalk-cdn.com/20190315/ffac0f30258ac796b51ecbe16d58a19e.jpg)

Apparently a good goose neck machine is damn difficult to find. I've been struggling with no spending hundreds on a machine light. Cobbling together horse crap and using old desk lamps.
A trip to home Depot for a shower cartridge resulted in an interesting idea that seems to work out in spades.

A gas appliance whip, some plumbing parts, and a lamp holder. Presto.

I remembered that the wardflex gas pipe is flexible but rather ridgid. The whip was only $15 on sale.
It wiggles like a bobble head, but it flexes really well and stays where I put it... Which apparently is too much to ask of most goose necks.

The old mill light can hit the road.... I'll make another one for the lathe with a bit more consolidated parts.

He bought the truck last summer, hasn't said what he payed for it. 1947 Mercury with 20,000 miles on it, totally original right down to the tires with the original air in them lol. Nice ride.
I can't read the tonnage, but it can't be much. What does the hood emblem say?

Got tired of climbing a step ladder to get to the drawbar on the mill. Have a 10 inch riser that Im too lazy to take out, hardly ever need the extra height but its there when I do need it.
Used a cheap butterfly impact and some scrap from the shop. Seams to work but had a hard time releasing the collet I'd previously tightened with a wrench. Will see if we get any slippage, never did before.

Someone made one of these on another forum so I blatantly copied it (but gave him credit there) Called a lantern chuck, for shortening small screws. The little brass bushings are drilled to fit the screw, its inserted from the back and can be machined with the shank in a collet. No more burnt fingers doing it on the grinder.

Thanks Shawn. He went to the trouble of pressing a 1/4 female hex into the spindle to hold screw driver tips thus giving a positive drive. Haven't tried this yet, hoping the clamping force will be enough.

Saw one of these in a tv series, sure it was placed there and panned many times as a subliminal sales ploy.
I bit !
Its a nixie clock kit. Hate to admit but I used electronics that had these for displays.
Interestingly none of these tubes seem to be available in North America, guess stock was purged when they became obsolete. Russia seams to have a good stock yet, this kit came from Lithuania with CCCP  proudly etched in the glass. Guess they're like me and save everything.

A few months ago, while strolling through a garage sale, I saw a rough cut piece of brass that was 2.25"x8".
The tag stated "grandfather clock weight $15".
It still had saw marks on both ends!
I did some negotiating and walked out with my prise for a mere $5.
Fast foward to tonight where I started turning it into its finall shape.

Its going to be a scale replica of a 18# Howitzer naval cannon.
They were originally cast in bronze, but, im not nit-picking!
It will have a final bore of .500" so I could shoot readily available muskrt balls. At this point Im mot sure if I will fire anything out of it.

I do have one, and will attach it before I post this. But, since I work with .50 caliber stuff all the time, I can tell you that you probably don't want to use any more than 20 grains of 3F black powder, or 40 grains of 2F black powder. When I say grains here, we are talking about grains as a measure of volume, not weight. Brass barrels won't be as strong as steel, so I wouldn't push it. Steel rifle barrels often go to 90 or 100 grains, but they make better use of the gases created by the extra powder because of the longer barrel. With that short barrel, you will probably find that you can cut the amounts listed above to 10 grains of 3F or 20 grains of 2F. Anything more will just be burning in mid-air and giving no advantage. Great fireworks effect at night, but really wasteful of the powder.


Something you need to know about powder: There are different grades that reference the granule size. Granule size is very important because within a given volume of powder, the smaller the particles are the more total surface area the powder has.  The greater the surface area, the faster it burns, and the greater the chamber pressures.  As a result, 3F powder has about double the force or perceived energy of 2F powder. ALWAYS use a powder measure to measure your powder charges. NEVER guess, and NEVER pour directly from a powder horn, can, or flask into the barrel. If there is an ember in the barrel when you add fresh powder, you'll wish that you will have had a very small amount of powder in your hand! If you pour from a one pound can and it ignites, well, it's been nice knowing you.


Make certain that any of your loading tools such as ramrods, powder measures, picks, etc., are non-sparking. They should be made from brass, aluminum, or wood. Some plastics are okay, while some can build up static electricity, so avoid them. Make sure that none of those tools are made from ferrous materials as they may cause a spark under proper conditions.


It should also be rather obvious that you should not smoke when handling powder, and keep smokers away too.


Here is a list of the powders that are commonly available, going from the largest granule size to the smallest.Please do not be tempted to use the wrong powder for your barrel size, and DO NOT use smokeless powder under any circumstances. The bang will not be any louder, and your projectile will not gain any more energy, but you could possibly kill or injure yourself or others. Err on the side of caution and you can fire your cannon many times, but if you err the other way, you will only fire it once because it will now be a grenade and not a cannon.


If you are interested in shooting blanks most of the time, you can do so by ramming three or four patches down the barrel on top of the powder and no projectile. Patches should be COTTON.  Don't use rayon, or any of the modern fabrics as they will melt and create a nasty charred plastic coating on the inside of the barrel. Not good.  If you want to fire some blanks, you can get away with using a newspaper wad on top of the powder, but newspaper will not work very well as patching behind a lead ball.


A word of caution: black powder and especially the black powder substitutes create a ring of residue in the barrel just above the point where the ball seats on the powder. After several shots, this ring of residue can build up enough that the ball and patch stop before touching the powder. This is a very dangerous situation because the air gap between the powder and the ball causes the gun to behave much like an obstructed gun barrel. Muzzleloading guns can become 'walnutted' (expanded) or even explode when this occurs. Because of this, you need to do a couple of things as listed here:

Cleaning: ALWAYS clean the piece after you are done firing it and are ready to put it away. If you don't have to time to clean when you are done, then don't shoot. The residues left behind by black powder and black powder substitutes are corrosive, even on brass. For cleaning, just use cleaning patches and hot soapy water and lots of it. Once it is clean, dry it out and that's it. Since it's brass, you don't need to worry about rust or corrosion for the most part once it is clean and dry. Don't use any oil on it, at least not inside as it will contaminate your powder the next time you load it. Black powder is water soluble, in fact it is made using a wet, water based process. Modern powders are made differently and require a solvent to dissolve the petrochemical residue that is left, but that is not the case with black powder.  If you use Pyrodex or a similar black powder substitute, you only need water to remove its residue also, as they are sugar or molasses based. If you wish to coat the inside of the barrel with anything during storage, use a vegetable based bore butter. It is easily swabbed out before you load the piece the next time.


If you use Triple 7 black powder substitute, you need to use 10% less powder by volume than you would if you were using Pyrodex or black powder. No matter what you use, always read the manufacturer's information on the container before using it.


What if you end up with a misfire? Wait several minutes before putting in another fuse, as it may be a hang-fire, which is a delayed ignition of the powder due to some unseen problem. I've seen hang fires of several seconds up to nearly a minute. Be patient and stay away!  After waiting for an appropriate time, insert another fuse and try again. If you try it three times and it doesn't go off, put the whole piece into a bucket of water and leave it like that for at least 30 minutes, 60 would be better. This ensures that water gets into all of the powder through the vent hole. After that you will need to "pull the ball" using a tool for that purpose and clean the barrel out entirely.


Lastly, I hope I don't sound like the safety police or anything like that, and I don't wish to insult anyone's intelligence. I just want to make sure that you can enjoy your new cannon in a safe manner for many years to come. I am amazed by the number of people I meet each year that have lots of strange ideas and myths about muzzleloading guns and cannons, and I don't know why more people aren't killed or injured by them. As a result, I am condensing what would make a small book into this one post. There is much more that could be discussed, but what I've posted here should be enough to get you started in a safe manner.


NOTE: The attached chart is assuming a steel barrel and using 2F black powder. I see now that the maximum powder charge for a .50 caliber cannon is about 45 grains on the chart. Once again, for brass I wouldn't use anything near that much.


If you have any questions, please contact me and I will be extremely happy to assist you in any way that I can. I have a deep passion for muzzleloaders and cannons, and if I can spread it to others in a safe manner, it makes my day.

You can always fire paper wads, like a starter cannon for yaht racing. A friend had one, and would bring it out to make some noise. Quite impressive the amount of concussion that puts out. I think his barrel was 12 inches.. it's been a long time so I'm a little sketchy.

Terry,
I appreciated your black powder post a great deal because I knew essentially on the subject.

Other than the obvious danger of pointing a muzzle at one's face, is there another reason for "NEVER blow down the barrel"?
Title: Re: What Did You Do Today
Post by: Terrywerm on April 14, 2019, 06:17:42 PM

Jake, you are most welcome!  Anytime I can get somebody pointed in the right direction with black powder stuff, I do it. I just don't like to think of people getting hurt. Following a few simple protocols are all that are really required. One of these days I will write a Black Powder Primer that I can post up here as a PDF or something, free to any that wish to download it and share it.  If he only ever uses it to make noise, chances are that 10 grains of either 3F or 2F is all he will ever need. Just impress on him how important it is to never use smokeless powder.


My very first cannon was built many years ago when I was in high school. It had a 7/16" bore 7" deep. My brother snuck it away to his friends place without me knowing it and they loaded up about 200 grains of Hercules Red Dot and lit it off. Luckily, it did not explode, but the trunnion pins were both shot out the sides and never found again. They were lucky they weren't killed! I still have the cannon, and will post a photo of it one of these days if I remember to dig it out.

So, who wants to learn about tomahawk throwing??  ;D


Ray, the reason we never blow down the barrel is in case there is unburned powder remaining in the bottom of the barrel. The atmosphere down there is depleted of oxygen, and if there happens to be a hot ember down there, a puff a air may be all it takes to get it to flare up and ignite the remaining powder that has now dried out from the heat of the recently completed shot. Unburned powder can occur if it gets damp from running a damp patch down the barrel and not getting it swabbed completely dry. The heat of the shot then dries it out. Black powder, as I previously mentioned, is made using a wet process. Modern smokeless powders are permanently rendered useless by water, but not so with black powder. Once it dries out, it's ready to go. So, blowing down the barrel could possibly result in a flare up in the face. 


The safe way to clear the barrel of smoke and embers is to drop the ramrod in the barrel just after the shot, then stroke it up and down a few times. This brings both oxygen and cool air into the barrel, which quickly extinguishes any hot embers that may be in there. A second advantage is that leaving the ramrod in the barrel until you add powder is a reminder that you have not yet added powder. If there are people around asking questions, it is very easy to forget where you are in the reloading process. Remember:  Powder - Patch - Ball or it won't shoot at all!  Of course if you are shooting blanks, all you need is powder and a plug of newspaper wadding to a depth that about equals the diameter of the bore.


Civil War re-enactors never pour loose powder into their rifles from a powder measure or a powder horn. Doing so was a Hollywood thing because it looked cool. Instead, they make up paper cartridges which you see them tear open, then pour the powder down the barrel. After that they stuff the paper down the barrel as a wad, and finally they drive the mini-ball (a type of bullet) home. The bullets did not need a patch to help them establish a seal on the barrel because they were hollow in the back. The expanding gasses of the shot pushed the sides of the bullet out to create a seal. If you watch re-enactors closely, they will usually run the ramrod in and out of the barrel to make sure it is empty and to extinguish embers before they pour in the powder charge for the next shot. In a real war, soldiers did not take the time to make sure that the barrel was clear before loading the next shot, as that was the least of their worries. We are not under that kind of pressure so we try to do things in a safer fashion.

I needed some thin brass shims.
 Drilled a 6mm dole in some mild steel, turned a 6mm spigot to fit, inserted the spigot in the drill, set it in the hole, clamped the die to the drill table.Punched a bunch of holes.
I was amazed at how easy this was.
 Cut the holes from the sheet and tightened then between 2 washers and turned them round.

That brass screen was probably more expensive than an actual water filter! No? I had done something similar before but used a standard under the sink 10” water filter housing I found free. The 5 micron filters are $10.

Whilst not technically a machining task I did do some mechanical work.
 My neighbor woke me up yesterday morning at 10 am, well I am retired, with the news my aquaponic system was leaking and watering his yard.
 I knew there was a leak somewhere as the sumps were lowering way too fast and had been trying to find it for the last 3 days with no success.
 This morning it was easy, water was pouring over the far edge of one of the grow beds.
 Some bird set bush tomatoes had set root in three of the beds and I thought I would see how much fruit they produced.
 It was a lot but they were taking a long time to ripen and their root system had gone ballistic and clogged the auto drains so the bed flooded and overflowed.
 Time to remove them.
Now for the mechanical part that was also yesterdays job.
 I had built a shredder from some old popular mechanics plans a few years ago utilizing an old lawnmower and had to rebuild the pulley system and get a new motor for it.absolutely required for this job as there was a barrow load of tomato  plants to pulverise for compost.
And it made that much, felt good but now I have to wash the gravel thats blocked by all the fine roots left in there and make a new solids filter and re plumb all the piping to fit.Still, well worth it from all the produce and fish I get from it.

I found a large filter body with a tapered base for my aquaponics system.
 Unfortunately the drain hole at the bottom of the taper is a non standard diameter.
 So I made a pair of screwed taper flanges from a couple of ally ingots I had laying around.
Single point threaded at 1.25mm they will clamp the bottom of the filter using a soft rubber gasket.
 The right angle fitting is as bought but the white inside one I had to modify a tad to provide sufficient thread to allow a very tight fixing.

The dovetail is just for mounting different work heads, like a quick change tool post. The whole thing swings back and forth on the lower shaft. I've made a couple of jigs for the bench grinder that slide and found the grit made the sliding rough. The shaft here is sealed so swings very smooth.

Your post came through as I was typing Shawn. Built it a few years ago, to grind the equivalent to acme lathe cutter, to cut racks on the shaper for a CNC plasma table. Intended to make other work heads but just now getting to it. Recently made this one, a wheel dresser and a drill bit sharpener.
Sort of a really loose copy of a Decal grinder. The housing is 1/4 plate for weight and stiffness, the knuckles to set the angles were made from a cast iron shaft I found, uses a tread mill motor so I can set the spindle speed for regular wheels or speed it up for diamond ones. Used a variable transformer to power the motor.
Will see if I can find some build photos.

All the adjustments are locked with split cotters.
The shaft that it rotates on is a section of sucker rod from a sour oil well. Incredibly tough stuff, slid back and forth through a packing gland with crude oil that probably picked up grit in the well a toughed hydrogen sulphide to boot. Miserable to machine though. Forget the exact workings in the depth set adjustment in the end, it moves the shaft in and out but rotating the shaft doesn't change the setting.

The housing was a weldment, 1/4 plate with pipe quartered to make the corners. Stiffeners were added to carry the work head and spindle. Then the whole thing was milled flat to align the bolt flanges and line bored to align the spindle and work head.

Tool score.
Bought these nifty hardened and ground “plate work” parallels from a guy at work today for $50.   The SHCS mounting pattern for the t-slots are for Bridgeport tables but staggering the screws it fit my cnc nicely.   Could have used these when making the riser fixture but oh well.   
I may try to add a new set of mount holes using carbide drill so they don’t stick out in back and risk smashing the belliws or control cabinet.

My F350 had a crappy aftermarket shifter handle that had a sharp edge that made it uncomfortable to shift.
Soooo a quick trip to Ebay and A few days later, I had a real life 8-ball delivered.
I didnt just want to drill a hole and shove it on, so I unscrewed the scuchion from the aftermarket handle, and bored and threaded the pool ball to fit.
I acidently scuffed the finish on the ball, but its 100% beter on the palm!

I didn't build anything, but I did my good deed for the day.

This little guy (squirrel) was being attacked by robins in a tree along side a busy road. We were on a walk and he scurried out of the tree and climbed my foot and didn't leave. Couldn't leave him there to run out on the road and get run over. His nest or mother was nowhere to be found.
Took him to the local animal rescue, made a contribution, and went on my way. He will get released in about two weeks she said. He's still pretty young.
Never held a squirrel before. Shot a few... Never held one.

They may be cute a fuzzy, but around here they're considered furry rats. Ruined the insulation in the shop ceiling. Charlie shot another one today. My buddies wife feeds the birds as many do, but the squirrels tool over to the point she said get rid of them. He borrowed my hi velocity pellet gun, 18 the first day so fat the tail pulled off if he picked them up by it. Figured he shot about 100 before he returned the gun.

After I rebuilt my Benjamin .22 break barrel, it’ll poke the arsehole out of a mouse at 18 yards. We don’t get near as many rabbits in the back yard as we used to  ;D

She doesn’t know that.... and it’ll stay that way.... cover of darkness is against the rules, I hear. But what they don’t know won’t hurt them. Or my wife... (Those bunnies sure do stink up the garbage can something awful before garbage day, tho)

I don’t want to think what she’d do if she caught me with the barrel peeked out the back door... wouldn’t be good. Good thing that pellet gun is whisper quiet. One shot - one kill.

We have magpies in the western US. I often see them when visiting family in South Dakota, Nebraska, Colorado and Utah. I also have seen them all around Minnesota except around the Twin Cities area. Since I never see them where I live, I guess I must live too close to Minneapolis!  Thankfully, our American magpies are not nearly so aggressive as their Australian cousins!

I love them, if you feed them they become friends, it seems they have a memory of up to 5 years so if they see you elsewhere they will pop down to beg for food.
I had one family of four that would enter the lounge and sing for food, an awesome sound, just hoped they wouldnt crap on the furniture.

Pecan trees suround my house. Pecan trees are self shedding. I now have to put a second windshield in my wifes van. The current winshield is less than 2 months old. Im not happy, nor is she.
I proposed a 20'x30' carport.
She said yes, but where she wants it would require one of the pecan trees to be cut down.
So, the chainsaw got oiled, sharpend and fueled.
Now I have wood for the smoker that will last me a few years!

Dang. Do you at least get some pecans from them???

Needed to do a job today that required a #1 morse taper.   Cutting from 4140 pre-hard material.  Really wish I had a CNC lathe but unfortunately I do not.    So I spent 45 minutes mounting the taper attachment and swapping out leads screws.    (The taper attachment has a special splined lead screw.)  Its really quite a pita.    Then to get the exact angle set and not rely on trying to guess based on hash marks, I calculated the cross slide travel for 1” of carriage travel.    Cheated using cad🤪.  Checked with a mag indicator in X and the DRO in Z.    Amazingly just eyeballing the hash marks it was almost dead nuts first try.      Anyway it is a good opportunity to get some photos and document the DRO reader mounting.    arrangement.

Got back into town today only to find that one of my strobe lights had quit working. There are four on the truck, two up on top of the sleeper, they are the typical LED "bubble gum machine" amber strobes. The other two are mounted to the front of the air cleaner housings. The one that quit working is on the front of the right side air cleaner, so I removed it only to find that its sheet aluminum mounting bracket was corroded too far to be of any real use any longer. I checked the left one and it was nearly as bad. These brackets were done by one of our mechanics about 7 or 8 years ago, and they were simply pinched between two pieces of the housing. Not worth a tinker's damn.


So I whipped out these two brackets in about half an hour once I got home. Tomorrow morning I will install them before having to leave to do a local county cleanup about 45 minutes from the shop. I'll add pics of them installed tomorrow.

I did hard labor. as a fat old guy, this was hard work. When I was younger, not so much.
I needed to replace the roof b4 I opened the pool to avoid the garbage dropping into the pool.

Post by: Carpenter84 on May 19, 2019, 06:06:39 PM
I wouldn't bother on a shed.
And if you're warm climate you don't need ice and water at the eve.

The roofing industry got right away from using felt under the shingles because it holds moisture under the shingle. Takes a long time to dry out. Reduces the life of the shingles.
Title: Re: What Did You Do Today
Post by: woodchucker on May 19, 2019, 07:46:49 PM
I put felt under them. Originally it didn't have it.  I'm going to anyway. I have my stereo in there and people get changed after volleyball, and it's blistering hot in there. I have a gable vent, wanted to put in a ridge vent, but just didn't feel like going out to get it after I stripped it down. I had these shingles from my house re-reoofing.  They used felt under that, and a membrane at the bottom, wish it were a self stick membrane., but it was just regular.
 I actually burned my knee, on the new roof. Nice blister from it. Put knee pads on it after. Stripped it in long pants, but it got too hot working in the sun. Was about 75-80 today.


btw forgot to mention that I did this with a raging back problem. I have been sidelined the last 2 weeks with a lower (lowest) disc problem. I could not wait to be done.  and now I am really done.

It produces a good photograph, nice, crisp/sharp..... Agree with casters, every machine I have rolls. The sander needed an upgrade, casters removed, were HF finest.  Of course that is sarcastic, typical of their stuff, looks like what it is, lacking in function.

Last weekend while working on a trailer, my dad calls and said, "My tractor wont start, can you bring one of yours?"

His old tractor had been spraying more disel on it than through it, so since it use to be my tractor, I ordered a seal kit for it.
I had today off, so I spent it "rebuilding" a Roosa master injector pump.
The kit had everything but one o-ring, so we got a lirttle down time riding to the parts house.
After a little adjusting and fiddling with bent throttle linkages, it runs like a champion. Happy daddy, and I didnt have to haul a tractor around!

I only hung up the tap twice. But didn't snap it. But gosh, I need to convert to 3phase so I can change the direction on a dime. Waiting for the centrifugal switch to click off before I can reverse gets kinda hairy sometimes... And my spindle brake doesn't work.

But I'm having a hard time getting a crown out of the plate. I'm facemilling, difficult to clamp the plate down to face the whole thing and moving clamps around to get them out of the way. But after giving up for a while I brained a solution I'll try later.

If you are clamping it in your vise too tight, you can crown it. it only needs to be firm, not gronked down.

I was not using my vise as my new PM 4" is too small...
It was clamped to the table. I assume the plate had a crown in it from stock, and each time I face it off, I'm just transfering the crown. Not to mention, the strap clamp shuffle was creating lap marks.
Before I face the whole plate too thin I'm going to sacrifice two of the holes, countersink two flat socket cap screws closer to the center of the plate, I'll make a pair of 1/4-20 t-nuts, and skim cut, flip, skim cut, and see how it comes out.
I had my vise jaw reversed so I could clamp the plate on the lip of the jaw, but it was blowing the plate, and I was having a heck of a time indicating the freshly faced underside to make sure it was flat.

Basically just chasing my tail.
If I can't get the bow out, I'll give up, give this 5/8" plate to my boss who is intrigued by the fixture plate idea, go get a 3/4 plate and give it another shot with what I've learned from this one. I'll still make money (over the material cost) but not profitable. But each new item is a lesson learned.
I have somewhat limited travel on my 9x42" table. My Y travel is quite wollowed so I really only have 6" of usable travel before I can barely crank the wheel.
But this is the stuff I need to figure out. Better to lose money while at home and figure out what I need to do differently, than when I'm in the new shop with limited time and need to make money to pay bills.


Edit: NOPE, I've changed my mind again. New idea...

At one point I had considered either doing a Woodruff slot on the edges, or shoulder to clamp to. But didn't once I realized how much influence I was putting on the plate.
I've been at the out-laws all afternoon, being bored, so I've had lots of time to think about what to do and plenty of time to not machine it....  :-\
I think my final plan is to square up a piece of 1x2 stock and affix it in a boss on the bottom side so it can be clamped properly in a vise. Then face it that way.
The client did say he wanted a fixture plate for use in a vise. I had asked him this question already but he didn't answer. He can use the block to clamp in the vise or take it out. Either way, I will be able to clamp it and face it square to my vise. He may have to take a skim cut in his vise if there is a deficiency. He's not paying much for this. $100.

Shawn, I have a couple of those fixture plates. The one I like the best has a places for 1/2” cap screws to go through the plate and into a T nut for holding the plate down on the table. You do loose a hold down hole for each 1/2” cap screw location. But I do not see a problem and have not had one, easy to work around…Dave

I attached pics showing the cap screw holes. Also showing you the block that I attached to the bottom/back of the fixture plate. The block makes it very easy for me to put the whole thing in the mill vise and clamp onto the block holding that way. The plate I’m showing you has threaded hold down locations and also has dowel pin holes that are handy for locating, squaring, truing, etc.

At one point I had considered either doing a Woodruff slot on the edges, or shoulder to clamp to. But didn't once I realized how much influence I was putting on the plate.
I've been at the out-laws all afternoon, being bored, so I've had lots of time to think about what to do and plenty of time to not machine it....  :-\
I think my final plan is to square up a piece of 1x2 stock and affix it in a boss on the bottom side so it can be clamped properly in a vise. Then face it that way.
The client did say he wanted a fixture plate for use in a vise. I had asked him this question already but he didn't answer. He can use the block to clamp in the vise or take it out. Either way, I will be able to clamp it and face it square to my vise. He may have to take a skim cut in his vise if there is a deficiency. He's not paying much for this. $100.


My fixture plate has a block under it, I clamp the block. It was originally made for my lathe milling attachment to extend it's use before I got the mill. Not sure if it deflects, but it does what I want, and parts have been coming out correctly sized. So I can't complain.

In preperation for tomorrows Memorial day celebration, I have rubbed and wrapped a brisket, cored 2 dozen Jalapenos, and mixed up 3 diffrent cream cheese stuffings (garlic parmesan, fiesta ranch, and onion and chives).
I have peeled and cubed 10#'s of taters for tater salad.
I diced up some ham, and green onions, and I have 2 dozen eggs hard boiling.
When it cools off this afternoon, Im going to clean and prepare the grill, and set up the picnic tables.

One of the guys is tiling the shower in one of our basements. The waterproofing system we use is made by Schluter. They sell a stainless niche shelf. They want $125 for it. Before tax and shipping. Nuts to that.

Stainless isn't so bad when you use the right tools...
Had the wholesale sheer it to size. Used a Walters cobalt 1/4" drill to pilot all down the back side, then a good 1/4" carbide 2 flute end mill with flood. Worked quite well. I bought two of each drill and end mill anticipating needing them. Nope, both used tools are still fine. Word!
And the swivel base on the vise came in handy.
I bolted the stainless to an aluminum backer for drilling and milling.
Used a carbide burr to break the edges in the slots. Also new and not Chinese. Ran like butter. Then sanded it clean on my stroke sander.

you pop them off. they break off when you pull to tight, or flex them back and forth.


you can use a plier to wiggle them.
Title: Re: What Did You Do Today
Post by: Carpenter84 on May 28, 2019, 04:41:45 PM
If they're on the floor I kick them along their length, on the wall I either use whatever is closest or a rubber mallet. My boss, Marc, likes to make a game of it to see how many he can pop off in one swing. Usually sends wedges and clips flying all over the place.

If they were installed correctly, without tile mud squishing out around the white clip, the clip breaks off below the tile. If not, it breaks flush, then you have to cut it lower with a knife.

They're quite easy to remove.

Finished the fixture plate.
With the block on the bottom, clamping in the vise was easy, and I was able to skim/face the top within .001". (I micd each corner and the thickness was within .001". Then I dropped the plate on my surface plate, knocked on it, no clunks on any corners or in the middle. I'm gonna say it's pretty flat.
I'd call it a success. As far as materials, I'm still about 75% profit. As far as time, I made about $2/h hahaha. Got a long way to go.
But it's a start.

Well finely got back in the shop for a while.   Started on my new project,  Old Sattley hit and miss engine.   The pushrod is about 3/4 to an 1 1/2 to short, and the cam follower is loose,  May have to make a new press fit hub for the cam follower, and will have to make a new pushrod.   It also functions as trip and reset of the magneto on it.   Thus have to have the proper amount of adjustment to get it to work. 
For now taking apart then will start building.

Post by: chips and more on June 03, 2019, 05:39:49 PM
I just restored a Cuttermaster. Made the solid index finger the other day. Not sure if it’s like the original factory? I just had a sample that was ground on so bad I just had to make a new one. But I also wanted an index finger with a sheet spring steel end. I think I will like the flexing end better than the solid no flex end. So I made that today…Dave

Post by: 4GSR on June 03, 2019, 10:27:50 PM
You're going to find that spring finger not to work as expected, but probably be okay for most sharpening jobs.  Most of the fingers that are used on t & C grinders is a flat blade shaped to almost sharp knife edge, more of a blunt edge, with a slight radius to the edge.  This is mounted to a piece that acts as an hinge and is spring loaded, where when you index the cutter being sharpen.  I'll have to dig out a couple of them I use and post pictures.  If I don't forget, I'll take some pictures and post.

OK Ken, I have plenty of end mills but intend on modifying small end mills (>3/16”) from time to time. Not much room to index on small end mills. Was thinking the spring finger can find the room in the fillet and also allow me to click my way around the end mill with the flexing of the finger. I will not know anything more until I find a home for the Cuttermaster in the shop. And that is a BIG BIG problem LOL. You can’t see me, but I’m shaking my head in disgust right now. I don’t have room for a pencil, let alone a +200lb metal thing…Dave

Hey, you haven't seen my shop!!!!  You can't walk thru it without bumping into something or knocking over a piece of iron!!

You're right, on the real small endmills, the spring finger will probably work the best.  Have fun sharpening those little bitty small endmills!  I've sharpen a few in the past and they are just not worth it in my opinion.  5/16 is about as small as I want to grind on.  Your mileage may result in better results than mine!!! ;D

Find you one of them Weldon End Mill Grinding Charts that show the primary and secondary relief angles to set your cutter grinder to if you don't already have one.

I worked today in a maple syrup co-op, (5) 40 million BTU boilers, fired on propane at full tilt about 2000 gallons of propane/hr (combined). When it’s sap time they can process about 10 gallons of dark amber syrup per minute, per machine, they have 7, but rarely run more that 3-4 at any time. Last year they processed about 740,000 gallons of syrup. No free samples.

They have sap, that’s been concentrated in huge silos, they process until late June to mid-July. They are starting to wind down on the syrup process, they are starting to gear up for the candy/liquor phase. They employ huge numbers, when the sap is running, after collection, they have about 75 year round employees.

Springtime!  The sap starts flowing in late February or early March, and the trees are tapped and the sap collected. Then begins the process of boiling it down. Around here those that do it usually have it all done by late March or early April.
We never purchase that fake stuff in the store any more. In late April each year we attend an antique tractor swap meet where there is a local vendor that makes and sells real maple syrup. A couple of quarts gets us through until the next year.

I like the real stuff, but I don't use syrup often. I am not a diabetic either, but the high sugar, then the drop ... it's like I'm a diabetic, I get the sweats, can't think.. I avoid the sugar high because the drop is a killer.
My doc had me buy a glucose meter, I'm in range, but you can see how high I get and how fast I drop.
But when I do have Maple Syrup it's the real thing. I used to stop in occasionally at a place in Vt outside of Rutland while skiing. Some mornings I would go out with my lady, or eventually my wife, they charged more for the fake stuff than the real stuff. Great waffles, with blueberry cooked in. Maple Sugar and Spice in Mendon VT, Route 4... excellent if you're ever in the area. They make the syrup in the resturant and you can watch during season.   The building surrounds the stainless water troughs.

People who have never had the real thing get so used to the fake stuff which is corn syrup, water, and maple flavoring. The fake stuff typically has a stronger maple flavor than the real thing. The fake stuff is often a bit thicker too. People get so used to the imitation crap that they are slightly disappointed when they get real syrup.


For those of you that are diabetic, I apologize. I guess this is just one of those harsh realities of life, and I thank my lucky stars that I am not diabetic, and for more reasons than just maple syrup!

Agreed.  I love the real stuff too but like Terry  brought up the kids hate it.   Only use about 1/4 the amount typically see people drowning their cakes using the corn syrup junk.  Small little bottle costs $18 but lasts a year or more.     Obviously not a big pancake and waffle consumer here.

Got another small side job today. A gentleman with a telescope part. He told me it's a lens for a camera that's designed to keep the telescope centered on a star as it moves through the sky for long exposure photos.
He needed 20mm taken off and re-threaded .75mm thread pitch.
Now, I'm rather pleased with myself, because it's these simple tasks I have a tendancy to royally screw up for the stupidest reasons... But not this time, baby!

Nailed it.
It was an awkward part to hold. 4 jaw Chuck. Needed about .050" worth of brass shims to get over that raised end.
Parted off 18mm, faced the rest. In the end I was .30mm long. He said tolerance was +/-1mm. I could only eyeball the length with a depth mic as I couldn't get the shoulder back against the chuck.
I'd call the threads a machinist fit. Lol. Not super tight, but zero wiggle. Not bad considering I can't actually see the thread. Even with my glasses on .. you're all about to meet the first 35 year old with an optivisor... Cause I'm getting one next week...
Only possible downside is my thread relief may be longer than desired as I cannot anodize the aluminum again to black out the shiny silver beyond the threads about .125". Maybe Charles can chime in whether that will impact the image of not. I can see it looking inside the tube, but it is blocked by several other bosses and shoulders. So maybe it's fine.
Anyways, I'm happy to not mess up something so simple.
Title: Re: What Did You Do Today
Post by: Carpenter84 on June 08, 2019, 01:05:02 AM
Oh, I also got the new bearings in the mill and all back together. I had to drill new holes for the shoulder screws in the back gear clutch as I may have found where my noise was coming from...

When I was reassembling, I was cleaning as I went. The cog between the pulley and the spindle, the valleys of the cogs were jammed full of grease, dirt, and junk. I picked it out and cleaned it up. But also added almost 1/8" of depth. So, then the whole pulley sat lower in the clutch. But also meant it engaged much better...

I tried it, a 5/8" carbide 2 flute. Top speed. No banging. And a pretty decent cut too. However, I have other noise now. Could be the brake rubbing as I shimmed it. Or, the motor belt is too tight. I tried a different belt that seemed close to size but is a hair too short. I had a hard time changing pulley speeds. Needed a screw driver to get the belt up over to the next pulley. So, the belt is far too tight. I need a new belt tho, the old one is cracking very badly. Hopefully that'll quiet tat part down and things will be good.

This is true. I may do it. Only since I cleaned the parts in the ultrasonic cleaner with a bit of degreaser. They were messy with wd40 prior. So the sharpie would likely actually stick and stay.

I would look for some kind of dry film lubricant to put on those threads.  Something that is not messy, may even find something that is already "black" in color. Some of the dry moly-cote stuff out there has a "black" looking finish to it.

no,no,no on the moly or anything. A lens has a protective coating for glare and other things. The moly may cause harm to the coating.  I would avoid that. Just blacken it somehow so the stray light does not bounce around off the bright al.

He picked it up today. He was very happy.
He informed me the shiny aluminum would not effect anything as this particular lens is only for a camera that tracks the stars movement. IF the shine created a halo, it wouldn’t effect the cameras function at all. But he said it was unlikely to create an issue even if it was an optic tube. And he said a sharpie would solve any issues just fine.

You might try going to a gun shop and getting some Birchwood Casey Aluminum Black. It is available from Brownell's, but being in the northern provinces, you might be better off trying a local gun shop, or maybe even a gunsmith. You might get one to blacken it for you at a reasonable cost. Brownell's sells it for under $9 in US funds, but the shipping would likely kill the deal.

Here's an outfit in Mission BC that carries it for $16 CDN. Shipping to you from there might be much more reasonable, but it does have to go by ground transit.
https://www.rustywood.ca/shop_home/birchwood-casey-aluminum-black/ (https://www.rustywood.ca/shop_home/birchwood-casey-aluminum-black/)



I have not yet found anybody in Ontario that carries it, it appears that your government may have some restrictions on the stuff. Some folks had some luck ordering it from Cabella's or Bass Pro Shops, but once again, the shipping will probably be high.

Beautiful warm morning sun...
I have to work today and we always have Sunday dinner at the out-laws the I have to come home and cut the grass then quality time with the boyo. No time for shop play later. So, up early to take care of business.

We have a Graco airless paint machine, have had it for a few years. Very handy. But it's use is limited to only spraying primer/ceiling/trim paint when we do a whole basement or large unfinished area as the overspray is messy.
I ordered a power roller. It was quite expensive... Instead of the paint being sprayed, it is pumped into the inside of a perforated roller as you roll. It also means we can paint all surfaces, not limited to ceilings and trim. So, basically you save all the tray time. No pouring paint into a tray, no dragging the tray around, no dipping the roller and dripping all over the place. You press the trigger and just keep rolling. I timed myself when I got it running. I painted 30 linear feet of wall in 7 minutes. And that's including the awkward learning curve of figuring out how to now deal with a stiff paint pressure hose dragging around with you, limiting and resisting your range of motion... Now, i can paint quite quickly, best painter on the crew, but 7 minutes crushes even my speed. So, win win.

However. The power roller kit came with a silly 20" pole. Barely long enough to do anything with. Definitely hard on the back and shoulders. this 6'4" guy has to stretch up then bend nearly right over to paint from top to bottom (yes... That's how you're supposed to paint. Full strokes from floor to ceiling. Not patches and blocks)
Ceilings were worse...

So I ordered a 3'-6' extension pole at another great expense. Same size as my normal paint pole.
The thing finally came.... The parts aren't interchangable....  ???
All the parts and accessories are all listed on the same damn page of the catalogue... I would have had to buy yet another roller frame with the right connection... IF I didn't have a machine shop...
 
One side of the connection is a compression type thread, the other is just an 1/8" NPT... Rather small for a paint roller, if you ask me. I predict I will snap this adapter at some point with just regular rolling pressure, 200lb gorilla, I believe it's coined.... 244lbs actually...  :-\

I may make two adapters in the event I break one.
Stainless.

There's also a gentleman coming in an hour to discuss another shop job. He has a small arbor press and wants the ram modified to accept letter/number stamps and other attachments. Neat idea. I've wondered about a letter press too. Expensive and hard to find. This is an elegant solution. Apparently you insert the stamp, press down on the part, then just a simple wollop on the top of the ram with a dead low.

In the time it took me to write this the sun went away...  ^-^
Title: Re: What Did You Do Today
Post by: Carpenter84 on June 09, 2019, 07:39:45 AM
Done.
Made the hole in the 1/8" NPT smaller than a standard pipe fitting so there's more strength. The smaller hole won't matter because the original fitting had a pin hole to meter flow. But this is unnecessary as the I am not a moron and won't crank the machine to 10 to try to paint. Also, due to the extra volume in the extension handle, I don't want the fluid compressing inside the tube (if the tube wants to expand) and continuing to ooze from the tip after the trigger has been released.
I believe this will suffice and now it's all down to this extension pole not sucking in general and this whole expensive endeavour being a waste....

Talking about using a hydraulic cylinder/press to stencil with.  They sell a stenciling machine that looks like a "H" frame press but runs on air.  It has a roller that you set your type in an when you hit the paddles, it goes down and rolls across your part leaving a stamping.

https://www.gtschmidt.com/roll-marking.php

Their stuff is high end, but you can buy the tooling and adapt it to you own equipment as you see fit.  The stuff is not cheap!  Can get some ideas from their stuff.

We were talking about fixture jigs, and custom V blocks. He's going to see how this works then expand from there. But that roller press doesnt sound difficult to make given the work is flat...

Between yesterday and today, at the range I shot about 1100-1200 rounds, of 22LR, using the new Ruger Precision Rimfire.

I shoot 5 targets of 10 shots each, a possible 100 points per target, or 500 points per cycle, my current average is in the 97-99 points per target range. The last cycle I shot was 100, 99, 98, 99 and 100, so a 99.2 average.

At work we are phasing roll stamping of our products in favor of laser marking.  If any of you are interested in these type of machines PM we might be selling them off gradually.  Ours are (were) made by Imperial tho.  Same concept.  Look like this but older and free standing on a base

Son and I went today too.   50 yards with a 1911 trying to hit a 5” steel gong.    Surprisingly after some practice rounds we were able to hit 3-4 of each 8 round mag.   
The 9mm evo scorpion on the other hand was cling clong clang every shot almost.    Way fun to shoot

Self healing mat.
The brand name ones are ludicrously expensive. The one I have is quite large. Not sure exactly. The 30x24 maybe? I bought mine at princess auto. No name, may not be the exact same material as the brand names, but a fraction of the price...


Maybe not as large as I thought.

As I said, there was no project in mind it was just a to see if I could sort of thing.
As it came out so well I thought I would make a flywheel for it.

Post by: woodchucker on July 17, 2019, 08:26:31 AM
Ok, I've got a question.
I see how you mounted it, and cut it... nice job.
But how did you index your holes for your centers? If I am correct , you don't have a mill.
Did you just mark it, center punch it, drill it in your drill press and put it in the lathe?
if so, I am impressed, since I would not think that you could do that so cleanly in a drill press.. so your marks must have been dead on.


Next, that's a lot of hogging out of material in a non continuous cut.. how many times did you need to resharpen your cutter? I assume you hogged out material using the drill press as well b4 removing most of that. Or on a band saw?


Just curious, always impressed what you can do with that lathe.
Title: Re: What Did You Do Today
Post by: savarin on July 17, 2019, 09:15:49 AM
Thats right Jeff, I went on the assumption that if the centre marks were out  by turning each end between centres that would keep it in line.
I used the angle grinder to cut the end waste but had the turn the middle down.
Those intermittent chips are really hot, it looked like I had measles.
As to accuracy I may find that the crank pin may be out a small amount, I wont know till I sling a con rod on it.
There is no plan its really just to see how and it it all works then thats a bonus.

The side mounts were bits left over from a hot rod shock mount project.  the bearing material is some left over brass.  The lower base is a chunk of cast iron I found.  The crank I did on the lathe.  I "kinda" did the same as you, but I clamped the sides together and bored 2 small holes  to set the center distance of the stroke.  This allowed me to have a bit of confidence that they would end up the same.  ;)   The connecting rod was the worst part, I did it 3 times at least.  Boring the big end to size and not going over... grrr.....   :'(

I still need to get some material for a piston and cylinder and figure how to hold it all together.

I'm making some more AXA tool holders. Something that's long been on my to-do list.
Something that was also on my to-do list that got bumped up pretty quick due to the holder project, was a vise stop. Just the simple clamp type.
I made it from A2, because I have a bunch of it. The metals wholesale has loads of A2 drops. Never asked why they have so much, but was told they sell more A2 and D2 than O1. Very small selection of O1 drops. Possibly something to do with tool and die manufacturing from general motors.

Anywho... Just a simple clamp style. 1/4" reamed bores, 1/4" stainless rod. Locktited on one side. 1/4-20 cap screw. I had a spring in there but it was just the right size to get caught in the threads and bind. So, out she go. And apparently the photos show all the lint from the rag I used to clean up for photo time, and the poor finish and crummy bluing. Lol. This was not the project, this was the roadbump in the way of the project. So, it happened quickly. I was more concerned about the sliding fit than the finish.
I milled the slot, drilled, reamed, then drilled, counter bored, threaded, before cutting the block in half to make sure everything lined up. My cheap dro's no longer function. So I rely on dials as best I can compensating for the backlash.

But, it fits very nicely. Very solid without much screw pressure. Now I can index the tool holders to face to size and setup for the dovetails.

 Very nicw Shawn. I have a small concern though. On the inside clamping corner on both pieces did you relieve the inside corner to all them to completely clamp onto the vise jaw?? If not it's a good thing to do in case of unseen debris.

That's exactly the plan.

Only issue I've ever had with the hacksaw idea/method was, it's sometimes difficult to chamfer or clean up the slot so it looks good and doesn't have burrs. I have some needle files, but nothing spectacular.

You could broach the corner relief. Get an appropriate tool bit, mount it in the spindle of your mill and use the quill as the plunger. Just a few stokes should do it. And look really nice.

well it works well. I did find you should not spin it too fast. it works better at low speed.

I used 1/2 neod. magnets, but I think I could have gone smaller to 3/8.
I used an aluminum shaft so I don't magnetize my chuck or collets.

Since my right eye (dominant eye) is not working, it was pretty difficult. I can't see clearly and when I look down, I can't see. So I think I did ok. It did take me some time. I got frustrated by that. And packed it up a few times... especially while trying to center for the bolt holes.

Birthday coming up, so shopping for a gift .... yes I'm buying LOL The question fly cutter or face mill ? Face mills from what i've seen so far use carbide cutters. Fly cutters I can use HSS tool bits.

Having asked the question earlier regarding finish and tool bits.  Taking knowledge gathered, putting together a grinder, get a few M2 tool blanks and get busy.

Found some 1/2 tool blanks,  before ordering thought I'd ask if anyone has a source for same they like?
https://www.travers.com/square-ground-tool-bit/p/22-501-032/

Grizzly has a green wheel 120 that looks good, have an old 6" grinder, runs good & smooth with the wheels removed. Thinking it will work just fine with new wheels, What would ya'll suggest as a ruff cut grit wheel for the HSS tool bit.. 80 or 60?

Thanks in advance,

Pep
Title: Re: What Did You Do Today
Post by: Carpenter84 on July 19, 2019, 09:35:57 PM
If the green wheel is silicone carbide you don’t need that for hss. I use two wheels for hss. My 8” grinder has a 45 grit and an 80. Then I hone with either an India stone or this cheap “diamond” plate/lap I got from Lowe’s. 120 grit is pretty high. You’d be using that as a finishing wheel only.

I paid $16 for m35 cobalt hss 1/2” x 4”. So that seems like a good price.

I don’t remember what mill you have. -ersonally id go facemill. I like the one I have. But I also haven’t used a fly cutter in some time.
Title: Re: What Did You Do Today
Post by: chips and more on July 19, 2019, 09:50:41 PM
I thought you used the green wheels to grind Carbide? The white wheels work well on HSS. I guess the gray ones also do a good job. The gray wheels are harder so maybe last longer but as you would guess grind differently than the white ones. Really, many factors but both would work. And green, gray and white are NOT the only choices. And sorry, I ain’t the expert! 60 grit sounds good to me.

Grizzly has a green wheel 120 that looks good, have an old 6" grinder, runs good & smooth with the wheels removed. Thinking it will work just fine with new wheels, What would ya'll suggest as a ruff cut grit wheel for the HSS tool bit.. 80 or 60?

Thanks in advance,

Pep


I always pickup old stock. I never buy the new stuff (except when I needed very small 3/16 for a boring bar.
I goto garage sales and buy used or new online of
MoMax
Rex
and a few others that are high quality.
They hold up very well.
I picked up a box of VR/Wesson a div of Fansteel for $3 for 6 pieces at a garage sale (price marked on box)
A friend gave me TOOL BITS made in USA, old stock and they seem ok.


I avoid the newer chineese stuff as much as possible.


You can do very well out there.

I use the “general” HSS when I want to grind a profile and use it for maybe one job. It’s MUCH easier to grind LOL. For my every day tool bits I use Super MoMax mostly. Not favoring, I just have been finding that brand/type a lot at sales. It’s a bitch to hand grind! But holds up well in use! Good Luck…Dave

A small project that took way longer than I thought it would. Quick fasteners for an ice cream machine. The originals were plastic, which cracked, and had stainless inserts, stainless on stainless is a recipe for disaster on something used a lot. The studs were wearing badly. Roughed these out of 2 inch aluminum, bored the ends for inserts, then made brass inserts 2 thou oversize for a shrink fit. Warmed the body with a propane torch and dropped in the insert. Milled the finger grips and powder coated them. Worked on it when I had time, mostly when the cabinet shop was too hot. Ended up taking about 6 hours ! Guess I'll eat half the time, he gives me quite a bit of work.

Nothing shop related, but it was a nice deviation from the regular work day yesterday. I was on my way back from Michigan and my youngest son met me in central Minnesota and we went off galavanting for a little while. Here is what we saw.

I thought you used the green wheels to grind Carbide? The white wheels work well on HSS. I guess the gray ones also do a good job. The gray wheels are harder so maybe last longer but as you would guess grind differently than the white ones. Really, many factors but both would work. And green, gray and white are NOT the only choices. And sorry, I ain’t the expert! 60 grit sounds good to me.

After reading further I've come to the same conclusion. Couple of standard wheels with two grit grades, ruff and fine maybe 60-80 or 80-120 should do the trick nicely.  Did catch an interesting article about using a diamond wheel dresser.

Making 4 more (larger) AXA tool holders. I could use about 10 more, but I figure every 6 months if I make a few more, eventually I'll be good. The last 4 or 5 I made, I made from aluminum. I fudged the dovetail and had to aluminum stick weld some meat back on and cut the dovetaik again. I'm much better at paying attention now, hopefully I don't fudge something else...

So far, 4 blocks sized, with 5/8" tool slot done (I'm gonna make two of them 1") and two of them have the dovetail slot cut. I'll cut the other two dove tail slots then setup the mill and cut the actual dovetails in a repeatable setup

Moving the funds set aside for the grinding wheels goes for a diamond wheel dresser.. better value

Try to find a cobalt HSS dovetail cutter.  It'll hold a cutting edge much longer.  Yeah, more expensive, too!  Of course, if you go with a carbide inserted one, they are much more expensive for the better ones out there.

Edit:  Here's a nice Shars indexable dovetail cutter that should work for your needs.

It takes a TDEX32_ size insert.  Didn't do a search for them, but they are out there.

right now I need a cooler too. The water is upto 90 degrees.. not really refreshing.
I haven't used the heater this year. I had to replace the tanks, they were 20 years old, and they told me it was time.


The of course when the guy comes and replaces them, he tells me I didn't have to replace them they were in good shape, but the rating required it. There's a new rating.

I like 1/2 drawers. I find that most of the stuff in the box stores and custom shops these days are 3/4 sides in the drawers. I don't think it's necessary. A waste of space and they look big.


I understand on the mounting to the log cabin. Any back stretchers behind the 1/2 for the mounting?

Messed with the new fly cutter, not real imprest or don't understand the usage. Think it is more for a finish surface cut.
once a part has been ruffed or cleaned up.

Bandnotsogood has a 6 insert 80MM face mill, 50 beans or so. Hell for that I'll give it a shot, might be a better option. Then invest a few real dollars and get a middle grad tool.

Attended the Scott-Carver Old-time Threshers Show this morning and caught up with a few old friends. Yup, I like old tractors, especially the steam powered ones! Also ran into a fellow that is into machining small steam engines, much as I am. Another fellow there had a very old sterling engine there that he bought from a fellow in Australia. It was a very interesting little engine and sure enough, I forgot to snap a photo!

Came home and hand sharpened the knives for two hair clippers and one beard trimmer, plus a butcher knife.

Next I'm headed out to the garage to make and weld up a turnbuckle eye for the rear door on the walking floor trailer that I pull at work. Leaving for South Dakota in the morning and will not be back until Friday, so I have no choice but to repair it myself before I head out again.

Im milling a piece of the battleship "Texas" down from .375" to .110".
The piece will then get dropped off at a local lazer cutter and 12 1&7/8" 5 point stars will get cut from it.
Those stars will then go to a custom rifle maker, and they will be inlet into the stocks of 12 custom ingraved battleship "Texas" commemorative rifles that will be auctioned off to help defray the cost of further repairs on the boat.

The steel will have the natural texture left by over 100 years of being exposed to the saltwater of the ocean.
The man I'm doing this for has several pieces that have the "Carnegie" stamp on them.
Several pieces were overlayed and riveted together, and every dozen rivets has the either the riveters , or the inspectors stamp by them!

Gave the fly cutter another try, slowing it did produce a better finish. The but, I do not like it prefer multi passes using an end mill.

A fly cutter is nice to use to create a nice surface finish on a large flat part - after hogging material off.
I haven't used one in some time, I made one a while back, but used the arbor for something else and never made another for it. However, there's been a few instances where I wish I still had an arbor in it.
My facemill is decent, but a nice, large surface area finish would have been nice. Like, on my fixture plate I made.
Title: Re: What Did You Do Today
Post by: pep on August 06, 2019, 08:48:58 AM
Shawn,
 What is it about the fly cutter that creates a nice finish, that a face mill will not?

I did get a good finish .010 - .005 using the fly cutter, hammering brothered me to get it.

 My mill is not a tank, but it is a robust bench type, gear drive, one step below a knee mill.

Why would not a face mill create the same finish. Providing the face mill, OD extended beyond the surface edge, as the fly cutter does?

Is it the single cutting insert the answer? You think the multi insert design of the face mill.  Introduces  variances in the depth of the cut, from one to the other?

And maybe why one face mill it 50 bucks and the next same OD is 100xs more.LOL

Do not need a mirror finish on the stuff i make.

Title: Re: What Did You Do Today
Post by: Carpenter84 on August 06, 2019, 06:58:43 PM
With a nice sharp hss bit in the fly cutter, and you can extend the tool bit to a much larger radius, with light cuts, .005-.010", you can get some really nice uniform surface finishes.

My facemill is a two inch 3 insert SEET12T3 facemill. It works well with my mill, but being 2", and my mill likely being out of tram, and I believe I may have some column droop, it's difficult sometimes to get a nice uniform finish. I'll get .001" lap lines. And on something like a fixture plate, that can be undesirable.

So in a case like that, I'd use a fly cutter. But for hogging material off a surface, the facemill is a lot faster and nicer than an end mill. But it does toss hot chips clear across my garage if I don't have a shield up. Lol.
Title: Re: What Did You Do Today
Post by: 34_40 on August 06, 2019, 07:06:07 PM
My 2 cents.   I made my own fly cutter, and I use it to make a final pass and get one even finish and remove the small design left by multiple passes with a 1/2" or 3/4" endmill.

Sometimes I like the "design" left by the end mills..  other times I prefer the look of the fly cutter. Mine is to small to do more than a few thou at a time. But as I said, I'm using it more for the finish.

Post by: Bill Gruby on August 06, 2019, 07:16:23 PM
 A flycutter was never meant to do heavy cutting. It is meant to be a finish cut only. Never over .010 and even that can tax it too much. Face mill is for heavy cuts. That's not my 2 cents, it's fact.

Yes, I did learn that the hard way, did not hurt the mill. But I know it beded the gears. Even at .010 I think I can live without the fly cutter.

Well I tried to make a video of starting to make a pushrod for a Hit and miss engine.    Did not do a good job as lost most of the video,  did get a couple of min of clip.

Even did some milling and broken set screw removal but when I went back to it all I had was static.

Better luck next time I hope

Eccentric Turning on a Lathe

Today I needed an eccentric diameter on a shaft. And for the record I really try and avoid using 4jaw chucks, rotary tables and a few other toys in the shop that I can’t recall at the moment LOL. As the pic shows, I just used a shim under one of the jaws of a 3jaw chuck. In the past I did all kinds of math to find the proper shim thickness (what a headache!). Also tried an indicator. This time I just winged it. The first shim was a little too thick. Made my eccentric lobe offset too much. A second try with a thinner shim worked great. No real big reason for using the hex 5C block. Just wanted a flat surface for the shim to rest on.

And for the record: What have you got against the 4Jaw? yes, you got it done... great, but I can't see any reason to avoid the 4 jaw.


So bud, what you got against the 4 Jaw?  :P
Title: Re: What Did You Do Today
Post by: chips and more on August 08, 2019, 04:35:24 PM
When you have a GOOD 3jaw, like a not worn out set-true, life can be sweet. Once you get the set-true feature calibrated there is absolutely no need to worry about run-out. So dialing in a 4jaw every time for concentricity would be a pain for me. The eccentric job I just did could have been a 4jaw job. BUT, it would have taken longer and not as fast for set-up… No shim, part was concentric. Put shim in, part was eccentric and lobe was cut. Took shim out, finished concentric. Job was done! You can’t be that fast with a 4jaw chuck.

Started moving my buddies house boat. Had a trailer built, with hydraulics to raise the top bunks and lift the boat.
Used his loader to move it.
Made it most of the way, then a wheel came loose. It has the type of hub that uses wedges to hold the rim on, never liked them, no wonder they aren't used anymore.
Right now its sitting on the side of the road while he gets another hub.

took a break from sand blasting yesterday and knocked up a con-rod to fit that crankshaft.
I started with a wedge of Swiss cheese,
and faced it into a block of Swiss cheese
I cut the block in half and soft soldered it back together, drilled it through the cut, thinned it down, drilled two holes in the end and bolted it to a 10mm flat steel plate with a keeper plate.
I got the keeper idea from here
   Build a Mini Steam Engine Plans  (https://www.vintageprojects.com/machine-shop/steam-engine-hobby.html)  and as it now looks like I am going to build a steam engine I will probably steal the Stephenson's link design from here as well.
 Then back in the chuck between centres and turned down with a slight taper towards the little end.
then flat in the 4 jaw to bore the big end out.
 I was given a set of telescoping gauges a couple of years ago and this is the first time they have been used.
 I like them.
I was able to bore the big end to around a thou under size so its a very tight fit on the crankshaft.
so I  run it in with the lathe, tightening it down after a while.
This worked very well and didnt flap around, the blue stuff is chain saw bar oil.
 Its still too tight so today I think some plastic for the rod to slide on and leave it running.
 An expanding reamer would be nice but I dont have one.
 The keeper plate and the corresponding part on the end of the rod will be thinned down to what looks right.
 My theory on the swiss cheese is the holes will hold some oil helping this along.
 Now I have to think of how I will make the little end.

Yea that kind of sucks. I have a guy doing landscaping here. His trailer was loaded with 10 tons of gravel, and he blows a tire coming into my driveway. He decides to ditch it on my front lawn, rather than ruin the driveway.  He's trying to jack it up in the grass... . it's not happening. He unloads it by hand... I'm impressed how fast he was able to. once he gets it unloaded he parks it in my driveway... duallies... The rim is toast.. same type with wedges. He's able to get a rim quickly , but the tire actually takes 3 days. Apparently that type of rim takes tires that are not that common anymore since they stopped making those rims...

Kelly got another hub, we cleaned up the bearings, and hauled it the rest of the way to the boat launch. Its now sitting at his dock.
He didn't seam to have trouble getting tires, but your right they're an odd size think they're 14.5 inch rims.

Rotary Broach Cutter

Today I needed a 5/32” hex cutter for my rotary broach. And I didn’t have one. More like I can’t find it, LOL. So I used my little surface grinder and an Unimat indexing head fitted to an angle fixture that I made some time back. And for the record (again!), I not a fan of Unimat products. But this little dividing head is symmetrically sized for my grinder and it does a fair job of indexing for my grinding needs. Anyway, about ½” hour later I now have a 5/32” hex cutter (+0.0025”) with a 2° back angle. I don’t use 1/2” HSS billet blanks if the final result is really small. It’s a waste of grinding time. I use 1/4” HSS round stock and fit it into a special made holder that then fits the rotary broach (see pic).

Definitely an unintended consequence Pep.
a failed lost foam brass casting.
This is the third time I have used it, this time for bearings and the other two for lead screw nuts.
The cross slide lead screw is made from this stuff and gives a very smooth feel but I dont think it will last.
Its actually in my scrap brass bin ready for re casting but as I needed these bearings I thought why not I can always make them again with the real stuff when I find some.

 When I worked for GM years ago I would like to have a nickel for every job done in a three jaw chuck that most would require a for jaw chuck. It was done simply because of the time needed to change chucks and set ups. It was SOP to do it. No there is nothing wrong with a for jaw chuck. I use one all the time now. Kudos for a job well done on that eccentric.

I also cleaned up a few shop loose ends I've been meaning to fix/complete.

Fixed my quill clockspring. Tried using the old one from that spare Bridgeport head I have, but it disintegrated as soon as I tried to preload it.
So, I repaired mine. Jammed some needle nose pliers in to seperate the layers, stuck a thick piece of brass Shim stock behind the end of the spring, used a propane pencil torch to heat and bend a new end. Used a brass burr to drill the hole and reinstalled the spring on the quill and all is well.

Also mounted that Noga immigration indicator holder onto a tool holder for easier lathe indicating. The addition of that tiny thrust washer makes all the difference in these little indicator arms.

Using the rotary broach is not just for CNC machines. You can use a rotary broach on a manual lathe, manual milling machine, drill press, etc. The pic below is showing how I just did the 5/32” hex hole using my manual lathe and rotary broach mounted in the tail stock. You would first drill a clearance hole and put a slight chamfer on that hole. The chamfer will aid in the alignment of the broach cutter. Then gently feed the cutter. You will feel a throbbing sensation in the feed. This is the cutting action of the cutter every time it rotates to the next facet. As soon as you stop feeling the throbbing that means the cutter has hit bottom. Then you are done and it only takes a few minutes to do! I got my rotary broach on fleabay. Was not in a hurry. Just watched for maybe a couple of months and then pulled the trigger. Can get pricey if you don’t shop! Could also make your own. Could be a fun project! Maybe the folks on MG could all get together and make a project out of it? Making the cutters is another story. Grinding HSS to an exacting size and shape could be a challenge for some Hobby Shops? Maybe buy the cutters and make the rotary broach?

ON EDIT:  The files are attached as a zip file. It contains the drawings in DXF, DWG, and PDF.  All dimensions are metric, so anybody still using imperial measures will need to do some conversions. Don't remember where I got the drawings from, but I did not see any copyright on them.

I have had my rotary broach for a loooong time. Since then, I have noticed several flavors in design. The plain and simple round one looks easy enough. You will not have the fine tuning feature for alignment but I don’t see a big deal. Just gotta make sure your cutters all have the same length. Like maybe the standard 1 ¾”? Making the hole in the round design is the only head scratcher. Need to do a little math and special set-up to make the hole on an angle, position and certain depth. And maybe with flat bottom?

The only thing I don't like about the one in the zip file, it has the thrust bearing in front instead of in the back.  I made one that didn't work out very well.  Never did go back and mess with it anymore.  I think my biggest problem was trying to cut heat treated 4140 steel.  Had a Rockwell hardness of around 32-38 HRC.

I would love to see the "guts" on the Slater one in the above pictures.  Pep, any chance of taking yours apart and showing it to us?

I agree with Ken that having the thrust bearing  in the rear would be a better option, but the plan gives a person a place to start.


Here is a site where a fellow built his own and he takes the reader through it more or less step-by-step: http://www.docsmachine.com/projects/rotarybroach/rb01.html (http://www.docsmachine.com/projects/rotarybroach/rb01.html)


This one didn't even use a thrust bearing. I suspect that it may work just fine as the thrust load may not be as great as one might initially expect.

Here's the best I can get out of my face mill. Nevermind the cutting pattern, more so the tool marks from the various passes. If this needed to be nice looking, my options would be to surface grind it, or the faster method and allowing me to leave it in the mill, would be to use a fly cutter to finish.

I also trammed my mill tonight. Long over due.... .005" out... Eep. And I have a .001" nod (over a 6” swing) I can't get rid of. But I suppose that's not bad for a column mill.
After tramming, cleaning and resetting the vise, and taking my time, I squared that block parallel on all sides to .0005". Not bad at all. It's a parallelogram in one direction because I squared the block in the vise with a square at one point which resulted in a .003" parallelogram, but using my squareness comparator/surface gauge I tested all sides, top and bottom, to be within .0005. certainly not gonna complain there. That's the best result I've ever gotten squaring stock on this mill. Ever.

Put it on your surface grinder and dust the surfaces.  That will tell you how flat and accurate it really is.  If you have a precision right angle plate to mount the block to, you can get it precisely squared up, too, on the SG.

The task wasn't to perfectly square the block. It was merely a test of the mill and my abilities. I have no purpose for this block. It will join it's other friends in the stock cupboard.

My squares aren't perfect, they're Chinese. But they get me close. I got this result because I didn't really put much effort into squaring. I was really only interested in seeing if I got taper in my cuts and how flat my vise can hold. Evidently good enough for my shop.

This is more of a what I'll do today, the motor for my mill. Replacement arrive yesterday, not bad ordered it Monday, installation begins after i hit post.

Simple enough, need to repair the burnt wire, add a new terminal. Maybe a hour, depends if the cat stays out of the way LOL, they are so helpful.

Wow.. there's a lot of heat in those terminals.
Before you power back up, pull one wire off at a time and clean the oxide off the post, washers, and ring terminals. The heat is caused by resistance in the connections. Id also suggest putting a bit of dielectric grease on the connections to reduce the corrosion in the future to prevent premature failure of the windings and caps.

Take pictures before you disconnect to note the connections.

If you are aware of all this already, then please disregard and have a wonderful day!  ;D

I’ll second the thought those motor wires look mighty crispy.   Guessing theres no overload protection?   Properly sized overloads would prevent that.   If theres enough slack you may want to cut back to undamaged insulation and re-terminate with new ring terminals.   
Clean and tight...

Well, you can heat shrink the damaged insulation. Replacing the stakons is definitely a good idea.
Adding a resettable motor overload to the circuit is always a safe, smart approach.

I use liquid insulation in difficult situations.
A) it insulates well
B) it seals from moisture and corrosion.
C) it is super easy to apply.
My lathe motor 1940's war time needed some leads. I used the liquid and never looked back.  But I would strip back to better wire then either crimp or solder a new section on after twisting.  Since it won't be strained solder is fine.

One hour of work ??

Well that was a nice dream, 5 hours later, few more parts. Dissembling the motor one piece at a time. So as I could manage the removal of the top of the gear box and spindle drive shaft, with the motor stuck on/in it.

Get it down on the bench, cut the lower motor bearing housing off.  Now exposing the motor bearing and gear box top plate.

Dawning a pickle fork, car guys will know what that is.

Slip it between the motor bearing and top plate. Small slug hammer, a few whacks the what is left of the motor separates from the spindle shaft.

Walla a rusted key is exposed 5 hours later, and realizing my plan was only 4 hour off .

A though accures:

Before the motor went south I was messing around with a face mill.   

Having had some start up problems with a fly cutter. Ordered a face mill from banggood to try, for 59 bucks what’s to loose, 6 inserts, 80mm (3in”) R8.

Jazzed playing with it making .030 cuts, no machine marks. It is worth a look, good bang for the buck.

Side 5, hunk of aluminum, got the wire, block clamped. Hit the run button, motor start to spin touch the work, and dies, humming, no smoke, no smell .

No load on it when it gave up the ghost, was warm, not hot. Just a machine failure, happens.

I wonder if the 3" is a bit on the big side? Someone with more experience can chime in.

I know with my 2" 3 insert, I can drive up the motor amps pretty quick with .030" cuts.
Title: Re: What Did You Do Today
Post by: pep on August 19, 2019, 11:06:32 PM
Thought the same and asked that question of the folks I bought the mill from. They said no. the mill is capable.

I do know a fly cutter @ .030 is not a good sound, the face mill a whole different story, i was happy to see and hear. Was running low & medium rpm range, best finish.

I will keep the fly cutter for real wide material .020 being max on the high side or deep if you like.

If using the face mill and this happens again well you and i will know that 2+2= do not do that shit .

A big + the key way and shaft are greased, should speed things up somewhat...:))

For $35 I can't go wrong.  they sell 1 each of the inserts for half the cost of the whole unit.  I could replace the inserts and holders for less.
Anyway. it's more than double elsewhere. I have a Clausing 8520, so not powerful, only an mt2, 1/2 capacity, but my ER32 holder will hold it, unless I turn it down to 1/2 shank.


With low power, I figured these might work for flattening the Steel Rail section when I can work on it again.

I have a 1" with the triangular insert, the insert is presented flat to the work piece. Works decent, nice finish. Light cuts tho... And the machine handles it well.

I also have a 3/4" 3 insert endmill that's good for hogging. It works decent, even with crummy inserts. Chips come off super hot tho.

Actually that cutter works quite well. It’s only cutting with the tips and the rest of the flats must just level and/or burnish the surface nice and smooth.

I don't believe my Clausing 8520 has the ability to turn a 2" face mill in steel... AL yes, Steel... no.


PEP, I agree with Shawn  your PM is underpowered for that size facemill unless you go super light cut, and AL... even lighter for Steel.
Like my 8520, you probably don't have the power or rigidity. Rigidity is just as important. If the head is bouncing, it is taking heavier cuts then lighter cuts then heavier...  so not optimal.


I could see a 2" face mill instead of a fly cutter, but a fly works fine mostly, except in the hardest of metals. A fly delivers a beautiful finish.

Post by: pep on August 21, 2019, 04:37:09 PM
I don't force feed the material removal. I agree with both of you the mill is not up to heavy work. For me the fly cutter was more problematic, and tested the mills limits.

The face mill is smoother working. .030 was the largest cut, and only made one pass. The little voice in my head was saying caution.  I'm going to look around, see if I can pick up an amp probe, reasonable.  Clamp it around the power cord have a look see.

Both the fly cutter and face mills primary purpose will be finishing. .020 > less passes. Even a .020 I do not like the action of the fly cutter, all that well.

If it should toast another motor, they are cheap, and i will stop using the mills completely,

 The mechanicals of the mill are a bigger concern. After seeing the insides unless some really stupid cuts are taken mill has a long life ahead.

Thanks for the input, food for thought, and respected.

I don't know how many amps your motor takes, but there are kill a watt meters and the like... usually upto 15amps. 120volts... you could plug into it and monitor amps.
Or get a clamp on meter. With a clamp on meter you will need a cord that is split so you can read the one leg.

no, but it makes it easier to read unless you are a lefty.
I suspect that the previous user zeroed it for left handed use.
it is not that hard, just requires a lot of patience to zero to 12'oclock.


I do it by backing out the tension screws removing the springs. sliding to 12 oclock.. sliding the head off the rack by moving it away from the rack (you removed the springs so it's capable) moving the head to the closed position, putting the head back on to the rack.. hopefully nothing moved, but it usually does. so keep trying until you get it zeroed or near zero.

I don't know about the Starrett calipers, I know on most other brands like Miytotyo calipers, they have a very thin pointer looking thingy that is inserted at the right end of the head next to the rack. It's pushed up in there to move the pinion gear off the rack and allow you to reposition by a tooth or so.  Have to see if I can find one and post a pic of it.

Oh, BTW- Nice find! Very nice find.  The 120's was my first real pair of calipers I've ever owned.  Had to retire them because they got too much wear in the jaw tips.  Couldn't measure in half thousandths like I use to! ;D

Oh, just thought about something,  I have taken mine apart before many years ago.  The four screws holding the front on, remove those screws and the front will lift off.  Clean all of the crud up that collects under there and re position the pinion on the rack and attempt to realign.  Should be able to get it close.  Last resort, carefully remove the bezel, with a hand puller, remove the hand, re position and put bezel back on.  I don't recommend this method, but at last resort, it does work.  The bezel was never meant to be removed by us tinkerers, but we know that don't stop most of us.

Wonderful.
I've used several of the cheap Chinese DC shunts, they work reasonably well. I have an ac/DC coil/shunt waiting to go into my big airco welder.
I cannot attest to their accuracy, but it doesn't actually much matter. After a short while you wind up figuring out the range of the machine based on the numbers, and can run accordingly.

When my lathe was DC it was a huge asset. Now, with the VFD, I have the display set to show the AC running amps always on the display. It would be nice to get it displayed on the control panel, but that's a low priority project.

Picked up an Airco high frequency unit for my big old Airco dip stick 160.
Finally weld some aluminum? Why, I think I will!



In reality, this is a hell of a find. Extremely rare. Great deal I think. $120. The guy didn't really know anything about it. He had bought it with an airco AC stick welder. Had intensions of welding, but never got into it. The previous owner obviously used the unit for high frequency tig welding and this guy only wanted to weld his trailer.

HF start and a foot pedal are two things I would love to have.   I got a smoking deal on a miller maxstar 150 STL inverter which was new in the case off ebay but it didn’t have the HF of the next model up.   Debated springing for the HF but for $750 I couldnt pass on the deal.   Lift starting the TIG torch is always a crap shoot whether or not it will stick and weld tungsten to the work if not done just so. 
Just a lack of practice but when I use the HF and foot pedal combo DX units at work OMG its night and day how smooth you can start and stop.   For a weekend warrior rig it does fine.
Another issue I found is the The unit itself has no problem running 100% duty cycle but  the air cooled torch gets smoking hot in the hand if you do much of a bead.   
Good thing is foot pedals and chillers can be added.  HF im not sure.

Greg. I may have questions when I start digging into the hf box. I'm not 100% sure on how to use it yet. I know the premise, but unsure of the logistics.

I have the dip stick unit setup to the nines for ease of use. All the semi automatic features that come on the big machines, I've modified mine to do.

I have a foot pedal for current, albeit, just on and off. So I don't have to whip out the arc and lose gas coverage. And I have a finger trigger on the torch for gas. Easier than a valve. Just a press of my index finger.

I've also added various selector knobs and switches to switch gasses without changing regulators. And a selector switch to control the relays for the foot pedal and gas switch when switching from Tig to mig and a spool gun (which doesn't work for alumimum... Think wire speed is too low, or, needs the hf box.)

Makes me sick, dad had a Miller Synchronize 300 welder back, at the family homestead, years ago. Had the foot pedal, bottle, water cooler, and all sorts of goodies to go with it.   Wanted to keep it, but just don't have enough current coming into the house to run it and the house hold both!  Been okay of most general welding, but the moment you kick in the HF, the meter starts to spin!  I put in half the cost of buying it so dad could get into the head rebuilding business that never happen. :(

What’s your house service?
Title: Re: What Did You Do Today
Post by: 4GSR on August 27, 2019, 05:44:24 PM
What’s your house service?

200 amp service with a 100 amp line coming in from the pole.  Was 100 amp service when I moved in. Forced to upgrade to 200 amp.  Fought with the electric provider about wire size.  They run no. 2 for houses and 4/0 and larger for businesses.  Can't explain it, that's how they do it down here.

Post by: Carpenter84 on August 27, 2019, 06:12:00 PM
The hydro company often installs whatever wire they want from the pole. There are open air wire charts for amperage. You get a lot of heat dissipation with open air wire. It allows much smaller wire size. 4/0 is standard for 200a for any underground service. We often see no1 overhead or 1/0.

The question was regarding the welder amperage being too high for the house.

The question was regarding the welder amperage being too high for the house.

Oops, the welder at 70% duty cycle on HF side pulls around 97 amps on 240V 1 PH.

forgot to mention, the welder was right next to the breaker box. Dad had it wired into a large 60 amp 4-prong plug and receptacle.  No. 4 gauge SO cord about 6 foot long to the plug. He had it on a 70 amp breaker, instead of of a 100 amp breaker.  The 100 amp took in both sides of the breaker box where the 70 amp breaker only took one side of the box.  As for as I know, he never tripped it.

Picked up another no.196 locally. $60. The crystal is pretty scuffed and it's missing the plunger tip, it's a liiiiitle bit mushy but it returns to zero and is much smoother than the one I tried to repair. Nothing is loose or falling apart.
And with the spare parts someone very generously sent me, I'll be able to finally put a 196 into service and use the deep hole attachment as this was initially intended for.

Post by: woodchucker on August 29, 2019, 10:15:00 AM
try some toothpaste... rub it in, then polish it up..
if you use a drill it will help, but too fast and you burn the crystal, too slow and it won't fully polish.


I use it on auto headlights, works pretty good.  I've also done it since on my crystals... it depends on the material and how far the scratches are.  you can try like a 1200 wet / dry paper to start if it's really bad, then goto the toothpaste.

Search eBay for watch crystal installing tool.  It will consists of a dinky press, and a bunch of thimbles of different sizes.  Probably no more than 20 bucks CAD.  What you do, is press on the crystal to bow it just enough to slip the bezel ring over the lens.  The ones I sent you should drop in with a snug fit, not needing a press.  That's how they are on the 196 indicator.  All the others, you have to bow the lens to get it in the bezel ring.

I attempted to make a crystal press, just a couple of pieces of aluminum.... Didn't work so well. I chowdered one of my big federal spare crystals. I have one more .... I packed up all the broken crystal indicators I have in pretty Starrett boxes and they're gonna get dropped off at the local (good) jewelery store tomorrow. The watch repair guy comes Wednesday. I'll be asking for him to call me to discuss whether he can replace the various crystals and maybe make some minor repairs/clean/lube. If not, then, back to the drawing board.

There is a product named White Diamond,  Advance Auto carries it here. It is very fine, use it to polish the aluminum wheels on the 34. The wheels shown, were purchased 2000, are raw aluminum and uncoated. Polished twice a year, some times 3. btw the lugs are chrome, mentioned to indicate how little contrast is seen from between chrome and the polished aluminum.

White Diamond is actually the same as jewelers rouge, very watery & thin, takes very little. Example if i were to use it for the indicator, I would wrap a rag, soft around the end of my finger, and wet it. Keep working it no need to let it dry or stand and haze.

I have been polishing aluminum and chrome for many years. Have tried most products for both. My requirement for a polish is 2 fold, easy, meaning does not take a gorilla force to get results. And any residue is removed completely with a couple of passes of a clean solft rag/towel.  Good lasting results .

I use two products
Turtle Wax Chrome polish, amazing on chrome
White Diamond, aluminum

Mothers, and semi chrome type of product, have one thing I find in common, that all leave a residue that take forever, it seems to get removed.

I can also vouch for the white diamond product, use it exclusively for the aluminum parts on my car.

There is also a product found in most auto parts houses that removes the haze from headlight lenses. 
Like Mr. Miyagi says wipe on / wipe off....   leaves the lens clean and clear - no buffing or elbow grease required.  I think it cost me 7 bucks.

I've never run coolant with/on face mills, and I've used some pretty big one's back in the day.  Like 8" in diameter with 50 HP behind it, spewing big chips everywhere.  That particular machine had a conveyor moving chips to a dumpster at the end of the machine.  In the home shop, my biggest face mill is a 3" and that's big enough for what I do.

I haven’t used the super big ones but at work we have a couple Sundstrand C3 Simplex Rigid-mills that have  (edit: my bad they are 40 HP) main spindles and 20” diameter cutters with (22) inserts each.   Those bad boys stay mounted in the machines perpetually its like a several hour project to remove and reinstall.  We use them to slab the faces of aluminum and bronze plate castings to thickness in one pass and the chips definitely pile up. Our guys use coal shovels and brooms to get it into 55 gal drums. Check out the gallon jug is like 6” dia

Random thought.

One reason going forward I only ever buy carbide endmills....   I abuse them buy running way too high rpm too lazy to check/change default 1000 rpm in CAM

And recut chips.   Surprisingly the 1/2" 4-flute im using in the video has held up for a couple years.  Sporadic use of course but at least 10-15 projects of various types.   
Its a SGS with the Tianamite (sp?) purplish color coating.

HSS cutter would be smoked in no time without some kind of coolant or cutting oil.

One thing I would love to start doing is making bigger DOC and less WOC with faster feedrate.  It's all the rage but the TTS collet system on the Tormach suffers pullout under those conditions.   I "customized" a nice set of 4-jaw chuck jaws due to pullout.

Took a break from constantly working to enjoy some fun. Took the boy up to the farmhouse. Jonathan pulled this 6x6 out of the hanger he was cleaning. Apparently it only took some carb love and fresh gas and this machine started right up.
So, with him sitting on the seat in front of me, went for a few rips around the property. Some nice fast straight runs down the runway, and through the forest trails. He was afraid at first but started "woo-hooing" on the second run.

It's a 2 stroke engine with a rusty muffler and still needs some tuning so it runs kinda hot. So the rips were a bit short due to some hot legs. The muffler was melting the plastic cowel so the boy was quick with a hose while Josh apparently picked his nose. Lol.

Didn't have any the correct size and no local suppliers, so I made my own out of some scrap 6061.
I don't think they turned out too bad considering no DRO and my dials don't lock. Had to just use my digital caliper and test fit along the way.

Not So Easy Knurling:
I wanted to make a small pin wrench. Thought it would be nice to put a little knurling on the handle for appearance and function. Weeeeell after many linear feet later of scrap material LOL. I finally got a result I could be happy with. Knurling is not new to me. Have even made special knurls to do convex forms. Didn’t give this job a second thought until I tried do it! I even had to consider knurling math that I always down play. And I had to dig out my Eagle knurling thing that I have not seen in years! The handle on the pin wrench is 12L14. The pin is music wire.

Nice to have the compressor outside too.   If you can stay off it awhile maybe seal it with something?  Last house i used something called Akona on the concrete.  Took several coats .   Its solvent based and pretty thin so it soaks in big time first coat.  Subsequent coats build up more sheen so depends how slick you want to get.   I havent seen it lately but It was years ago and the eco police may have banned it since for VOCs

thanks to the mill, I was able to drill out the rods in the endcaps of the pool pump.. so much more accurate than a drill press. Dead on, didn't ruin the threads, and was able to tap the threads after.  The old threads came out as a coil.


Improved my shop vac , I drilled some holes in the floor piece of the 1.5 " floor pieces. going to do more, remove material and make teeth, it improved the draw and stops grabbing the rubber pads... now fillings go up the hose.  after the 1.5 inch I'll do the big 2 1/4 pieces.


Ive got some sheets of plexiglass.  bought at a garage sale years ago, and can't get the paper off.  Going to try again and make some blast sheilds for swarf. The work I did on the anvil is everywhere. it would have been nice to held some of it in.

Tossing out another idea for your blast shield. I use magnets, to hold the ends in place. The clear windows are from a grinder full face mask.

I wanted something that I could adapt to different material sizes, quickly. The reason for the face mask material, easy to get, & consumable.

 First time user,  carving out the standard tenderfoot project .. T nuts.  Then first mod, after a swarf storm . LOL

Dad had a big No. 5 jig mill back at the family homestead.  He built a box around the table to contain all the shavings made. Made it out of 3/8" thick junk plywood, stood up about 16", the front had swing open doors that could be removed when needed.  Worked out nice, kept the shavings to the front of the mill instead all over the place for 10 foot around the mill previously.

The chips flew 4 feet away and embedded itself in cardboard  and the rubber mat. I have a 50lb magnet with a coffee can so I can just drop the chips and am never done.


I'll build something similar to keep the chips close at hand. it will also help if I use coolant...

Interesting, I guess the good news, there was enough material there so as not to get into the valve seats. At lease it did not look like it.
What are the holes for, head bolts? Made good use of the 4 jaw.

 Between you and Savarin i have seen some interesting ways for mounting parts on the lathe, pretty cool.

Got a question have you ever though about making a mount for the camera. That could be hung on the end of the tail stock, using a chuck.

 I bet a go pro would be real easy to do that with, what a shot that would make.

I though it would be easier to mount it in the 4 jaw than mount it on the mill table.   
I worked. the valves are inset a little did scrap the top of the seat area but now where they set.   
Just got this camera,   Had it on a tripod,   used a barrowed go pro a little on one of the other videos,  Did not do good,  old and kept not recording.  May have been my fault   Still not use to doing camera when working.

Well I’m signed up for a local industrial auction tomorrow.   
Couple really cool items I’m eyeballing just hoping they don’t get bid to the stratosphere.    One item in particular I’ve been on the hunt for for years.  Most are trashed or go for way high or are cross country.   I may just be “that guy” that overpays.   We’ll see.  If I win anything I’ll post it.   🤞🤞

Only won one item.   Not the most thrilling score but for $70 not bad.   
   (https://uploads.tapatalk-cdn.com/20191004/1e2969e6e95dbbe4b4439ca0be14b4d1.jpg)

Every thing else I bid on went for stoooooooooopid money.   Even willing to overpay but at a certain point it makes more sense to buy new.

Look like its been painted see pallet, always a concern in my book. I've seen body filler on machines to hide stuff. As to bidding so high, buying new becomes the better option.

Not a big auction person myself, however what little I have observed. That seems to be the trend.
People buying  name, never mind the thing is worn out. Also I tend to be leery of used because of the users.

I am leery of newly painted equip. Usually just brush over the existing stuff. Yes, they hide cracks.
Got burned on something like that.  They left a repair that I could see, but hid stuff that I couldn't. I was concentrating on the repair that they werer showing, that I didn't notice the hide under the paint.  I think they were hoping that would be the case.
only $300 lost... I learned.  Could have been worse.


But buyer beware on newly painted objects.

Yep.  As a rule I agree with new paint being a major red flag on used equipment especially when the overspray is literally on the friggin skid! LOL.  There are no shortages of gooberheads with paintbrushes
In this case however I actually went at lunch and personally inspected the stuff I wanted the day prior to bidding.   The base was painted but it wasn’t an original part of the Diacro machine.   They obviously had a base from another machine and repurposed it for the shear.  Those shears were designed to sit on a bench or be mounted to a base as desired.   The machine itself was in really nice shape with the OE paint.  The hold downs were missing but it had the optional micro adjust back gauge.  Usually those get busted or gone and they added a nice aluminum plate between the cast iron base and shear.   I brought some 18 ga SS material  to test and it cut beautifully even with no hold downs.   No burrs etc. 
But in the end, in spite of it being pretty nice there was no way I wanted to pay 1250 plus the juice for it.

I got the 12 inch model off Crown Assets a year or so ago for $315. Very nice unit. Looked like new, the cutting edge and anvil is reversible and flips to give 4 cutting edges, the first edge is still sharp. Made a stand for it. Awkward to see the cutting edge to align material, the Hold down is in the way.

If that was not bad enough, all the dirt had orange over spray, so if the DP was lifted  you would see the dirt image of the DP.

Thanks.
I chucked a length of 6mm stainless in my home made ER chuck.
Turned the end to 4mm and used a die to thread it.
I then slide the rod out further so the knurler wont foul the chuck.
The knurls are straight cut wheels in my home made cam jack knurler.
On a side note the shafts the wheels turn on are worn down so far that the wheels can wobble a lot.
I believe this has helped to align the cuts.
I dont think I would like to use a bump knurler after finding out how much pressure knurling stainless takes.

Angular Contact Bearing Gauge...
Been working on a high speed spindle that needs angular contact bearings. To get matched bearings has a ridiculous price to go along with them. And I totally get it. But I’m a Hobby Shop not a production shop and don’t plan on using the spindle but for limited use. So I feel flexible in my approach to repair the spindle. If I choose to procure just plain old bearings. I would need to know the register between the outer and inner races to get pre-load correct. So I made the collar thing and it mounts to a dial indicator as pictured. I also realize that my thumb pressure is not the same as the pressure on the bearing when installed. When I scoot the bearing over the stylus I get very repetitive readings. The indicator is 0.0001”. The bearings are 8 bucks instead of 200 bucks each. I will soon find out if my piggy bank saved any money! The original spindle design does not allow for any easy adjustment for pre-load. But now knowing the register between the races. I should be able to adjust accordingly.

I'm no expert at using spindle bearings other than those you get off the shelf.  Is this a OEM spindle you're trying to install new bearings in?  Or is this a shop made spindle? 
Title: Re: What Did You Do Today
Post by: chips and more on October 19, 2019, 01:59:44 PM
The spindle is OEM and set-up with two angular contact bearings that are in a preload condition. I’m no expert either, but have doing enough of these things to know that…the correct grease is very important, everything that you are doing can’t be clean enough, getting proper preload is a PITA and there is more but can’t recall at the moment LOL. Even when I think I have it all done and correct, then test, I could get bearing skidding or something else bad.

Thanks, glad I had the overhead crane to get it up there. The bore was so badly worn alignment was a bit of a guess, went off the outside of the tube. Blocked off the side of the dipper and hoped they'd done the same, a little miss-alignment would never affect anything. The pins Cat used measure 6 thou under 40 mm (great mix of units) so waiting for the new shaft to come before I do the final bore on the bushings.

Internal Threading:

Had to do a little ID threading today. A while back I found some CNC ID-OD threading cutters. I don’t have the machine(s) that they would be properly used on. But they were soooo cheap, new and less than the cost of scrap Carbide. So, I bought them and tried to find a pigeon hole for them in my shop, LOL. Got to thinking…and figured they could be used as a regular threading tool on the manual lathe. Sure enough, and it works great! It sure does beat the hell out of hand grinding a HSS bit!!! And I’ve got 4 lives on this cutter.

Did a bit more for the possible steam engine.Found this chunk of steel of some kind.
 main-cylinder-1 is the look when the manually placed centers are not centered,
That spiraled around the bar but eventually it reduced to a smooth bar where upon I cut one bit off and turned it down and bored it out.
I thought I would try and attempt the "most tool stickout" record.
main-cylinder-3
I had to do that to sneak up under the jaws. Around the middle a harmonic struck up that I dampened with a wood stick.
 but a quick rub with some 1000 grit wet and dry removed the look.
main-cylinder-2

This is not the main cylinder of the engine but the front part that hopefully the big end of the piston slides in and links to the crankshaft. (I dont know whats its real name is)
Now onto the main cylinder whilst awaiting parts for the bino and to remove the procrastination regarding starting the mirrors.

Small Steel Pulley:
Needed a little larger diameter “V” pulley. So I made one today. I plunge cut the “V”. My lathe can handle it :), no chatter at all. The knurl on the one side of the outer flange is used to help hold the pulley still while you wrench on the draw bar. Surface ground both sides to make it look pretty. Only took about 1hr to make. Actually, the hardest part was drilling the set screw hole. The darn “V” was causing all kinds of drilling and tapping issues. Next time, if there is one? I will make the threaded hole first. Then do the “V” groove.

Making a few more blanks for my grips project.   Revising cnc program for the thicker stock.   I really need to make myself a better saw stop.  and a mill stop for the Tormach.   For now I just ghetto-rigged stops up with whatever I had.   
Only need one clean/square edge on the blanks so a very simple one pass on the BP then a light file.

Almost forgot about my new to me Dake shop press I won at auction a few weeks back.    Had it apart to get it in the basement. Cleaned it all up cuz it was grimy and oily.   The piston seal leaks so I need to order a replacement.   The pump unit is still on the bench being cleaned up.  Went to Home Depot and got some locking casters for the legs.   Now it can roll around my shop and be parked out of the way when not in use.    Space is getting tight down here!

Got this done today, finished the cylinder, the holes all around the middle are exhaust ports.
I turned the piston on the con rod in the hope that kept it concentric with the bore.
I have no idea what I'm going to use for piston rings yet.
The width and depth of the piston ring recesses are exactly the same measurement but dont look it in the image but I expect I will have to cut them deeper when I make the decision.
Shouldnt cause a problem as I used the collet chuck on the con rod.
I have no idea if this will work as I hope it will but wheres the fun in knowing all the answers.
It should run as a two stroke with two power strokes per revolution.
I've relieved the middle of the piston so its at ambient throughout the majority of its movement.

Title: Re: What Did You Do Today
Post by: Terrywerm on November 12, 2019, 11:09:41 PM

That's going to be a steam engine, correct?  Rings in steam engines exert very little pressure on the cylinder walls, they are not real tight like rings in gas engines. They simply do not need to be real tight since you do not have the extreme cylinder pressures of internal combustion. If it were not for the fact that you are making a uniflow engine with those ports in the middle of the cylinder, I would recommend trying an o-ring or some graphited packing material in place of cast iron rings.


As for making cast iron rings, there are a number of ways to do it, but the hard part is getting them to be steam tight, and sadly, greater pressure against the cylinder walls is not the answer. The problem is due to the way most of the rings are made, by making a 'cylinder' of cast iron with the OD just slightly larger than the ID of the engine cylinder. The 'cylinder' that the rings are made from is then slotted, and finally the individual rings are cut off. Since the ring is truly round as made, once you compress it to fit in the engine cylinder, it is no longer a truly round shape, and will allow minute leaks between the ring and the cylinder wall.



There was a method for making plastic rings that avoided this problem, and I read an article about it. I will see if I can find it for you.

Bronze is an other option for rings in a steam engine. Have the added advantage of not rusting when you get condensation in the cylinder.

Another job rolled in today requiring 4 pcs of stock cut on the bandsaw.   So before starting I decided it was time to make a better length stop.    Head scratched a few minutes and decided to use some surplus 80/20 pcs on hand.    Milled a 1”wide pc of aluminum angle and drilled some mounting  holes.     For non uber critical drilling work,
I use a 1/2” dowel as an edge finder,   Put spindle in neutral, walk over to the edge while rotating by hand.  Soon as I feel friction spinning it I zero the dro, move back .250 and zero again.

C clamp in location, transfer punch hole loc and hand drill for 1/4-20 tap.    I find when doing these kind of off hand hole drillings its good to start with a small drill.   One that easily centers in the transfer punch dimple and relievs the chisel edge of the finish drill which follows nicely and stays centered without walking.   

Got it mounted now it will be easy to measure and set the sliding stop.
I plan on removing the bar when not in use so its out of the way.

Another job rolled in today requiring 4 pcs of stock cut on the bandsaw.   So before starting I decided it was time to make a better length stop.    Head scratched a few minutes and decided to use some surplus 80/20 pcs on hand.    Milled a 1”wide pc of aluminum angle and drilled some mounting  holes.     For non uber critical drilling work,
I use a 1/2” dowel as an edge finder,   Put spindle in neutral, walk over to the edge while rotating by hand.  Soon as I feel friction spinning it I zero the dro, move back .250 and zero again.

C clamp in location, transfer punch hole loc and hand drill for 1/4-20 tap.    I find when doing these kind of off hand hole drillings its good to start with a small drill.   One that easily centers in the transfer punch dimple and relievs the chisel edge of the finish drill which follows nicely and stays centered without walking.   

Got it mounted now it will be easy to measure and set the sliding stop.
I plan on removing the bar when not in use so its out of the way.

More little upgrade projects.    Since I don’t ever use flood coolant I decided to repurpose the m8/m9 relay from the coolant pump to an air solenoid valve.   Stacking it on top of the valve that powers the drawbar collet.   Brain-farted and inadvertently pressed the manual over ride button on the drawbar valve while working and boom.  Out fell the tool in the spindle right into my previously semi unscathed vise .   Amazingly the tip of the tool didn’t chip at all.   Probably because its hss not carbide. 
Temporary rigged everything with wire nuts and it works good.   Now I’ll be able to have a stream of air blowing away chips while cutting and turn it on/off manually via the screen and in the g code.
To date I have been using the air gun manually blowing the chips but it requires opening the doors.   
Ok don’t all play tiny violins at once but behold the vise ding

Incidentally the foot master leveling feet worked great for gaining access to the rear of the machine.   Raising the pads then it sits on the rollers and allows moving the machine very easily.   Moved it away from the wall to get at the valves and wiring in back.   I will need to re-level it after moving back into position.  The sheet metal base is flexible and that transfers to the machine.    Well worth not having a huge project to move it otherwise.

Finished off the air blow system tonight.   Made a little bracket to mount a flow control needle valve, got the machine moved back.   Had to break out the level and crawl around wrenching on the leveling feet to get it dialed back in.
Now i can turn off air via the coolant button on the screen.   I found my quiet little compressor is great for tool changer but it won’t keep up at constant unless I dial the air flow down.   I set it to the max flow where the pressure maintains while the compressor runs.

I’ve had this corner radiusing gizmo sitting around for awhile but hardly use it.  Came with a mystery cabinet “with contents” picked up at an auction.   It fits barely in my 3 ton Kenco punch press but kind of a pain to switch out with the whitney button die set up.   Works beautifully in the shop press tho.   
Now what the heck to I need to put radii on Hmmm.

As swmbo went out for a ladies lunch I managed to squeeze in some shed time.
Set up the vertical slide to cut the slot in the cross-head guide.
I started by using a 12mm cutter but it really didn't want to go so I drilled a 12mm hole then used an 8mm milling cutter to make the length of slot followed by 12mm then 14mm.
I thought it came out mildly ok.
Then I flipped it over to do the same thing on the other side.
All was going well untill I noticed the time so did what we all know is fatal, I started trying to hurry.
Bad move, the vibration of the cutting had (un-noticed) by me tilted the vertical slide and made a curve in the cut as shown by the red marks.
I will attempt to remove it with a 16mm cutter and hope for the best.
Title: Re: What Did You Do Today
Post by: woodchucker on December 09, 2019, 07:59:19 AM
does not look like a 16mm will take that out.
The curve looks to be more than 2mm. And 16 will only remove 1mm from each side.
But I could be wrong.


So is it critical that it be straight?

No, just for looks and to lower my annoyance level. :41:
Just goes to show what hurrying can do, I cant believe I didnt notice the slide moving off vertical.

Repaired a severely worn out bearing seat on a snowblower shaft.
Turned the worn section to clean it up, brazed the worn area, turned it to size. Then slotted the keyway on the lathe like a shaper. Haven't done that before. Worked nicely.
Except for that chowdered section at the end, it seemed the shaft hardened from the torch heat. It's quite hard. Tore up the hss bit a few times.
I find it odd that it hardened from the torch. The shaft was never red hot, and it slowly air cooled. No quenching. I didn't want to bend the shaft from the heat.
Oh well. Client is happy. Fixed his old craftsman snowblower project.


On second thought. The auger is welded to the shaft. Maybe it's that weld that hardened the shaft...

At last I scrounged a bit of shed time and removed the curly wirly slot, didnt have a 16mm end mill so used an 18 mm.
That did the job.
As a design feature (lazy) I have decided not to open out the opposite side as you never know I might need more access that side.
Also indexed and marked the cylinder head for the fixing bolts.
I used a prick punch in the tool holder and slid the saddle to make the mark then transferred the plate to the bench to go over the small marks with the centre punch. 
In my usual manner of going a tad over the top with fixings it will be 12 x M3 bolts.

Had to do some serious re-thinking on the steam engine.
The pictures are hopefully in the same order down below as the text.
1) I thought I was being clever and screwed the brass cross head part to the piston rod. Silly move, from one end to the other on full travel there was a teeny weeny amount of miss alignment so the assembly jammed.
 2) Ok, make a joiner so it can move a little.
  3) Better, it now can slide without jamming but... the cross head bearing/piston now sits at the wrong end of the cylinder and (4) pokes out at the other end of the stroke
  5) No worries, make 6 standoffs
6) and extend the cross head slide tube
  Now it sits at one end of the slide
  7) and sits exactly at the other end of the slide on full travel.
 It now moves from each end of the stroke without binding anywhere in its travel.
I guess this is what happens when you dont really know what you are doing and have no drawings or plans to work from.
Title: Re: What Did You Do Today
Post by: Terrywerm on January 01, 2020, 02:56:49 PM

I always much prefer to give praises for good work where praises are due, and highlight the good things. Regrettably, this is an instance where I have to point out what is wrong with a design. Despite your very best efforts, the crosshead guide and cylinder bore are not truly parallel and may also not be concentric either, causing the binding problem.


Sadly, there is a flaw in the design of your work around for the real problem. Once you create your pivot on the crosshead where the small end of the connecting rod will connect to it, you will have two pivots relatively close to each other. This will result in the forces on the connecting rod trying to rock the crosshead side to side (or up and down) inside the crosshead guide. Now, assuming that the engine is designed with the cylinder and piston rod lying in a horizontal configuration, when the piston end of the crosshead is pushed down by the connecting rod, it will rock slightly and try to push the piston rod up, creating excessive wear on the piston rod and the rod gland. Those same forces will cause excessive wear on the crosshead and guide as well. The added friction of the crosshead trying to jamb itself in its guide would result in some serious power loss in your engine as well. If this is difficult to visualize, let me know and I will put together a quick drawing and post it.


Your best option for proper repair would be to make new crosshead guides of correct length, the bores of which must be both concentric and parallel with the cylinder bore, no ifs, ands, or buts.


It is important to remember the purpose of the crosshead:  to absorb the side or angular forces created by the connecting rod so that the piston and rod are not affected by those forces. It also guides the piston and rod in a straight line at all times.

Found a Mitutoyo Height Gage in one of my piles of crap. Didn’t even know I had it LOL! Needs a knob and scribe. Today I made the knob. Took me about 1 1/2 hrs. Made it out of Delrin, only because I have a lot of it, any plastic would have been fine. The knob needed a hole with a flat. So….I made a cutter and used my rotary broach…easy peasy. Love that thing! Went over to the mill and made the scalloped OD on the knob using table coordinates. I really don’t want to drag out the rotary table!!! I haven’t for decades so why start now! And then back to the lathe for the finish work.

I know what your saying Terry and fully agree with it.This is really just a set of attempts to try something from some bits of scrap and has grown like topsy.I'm probably digging myself deeper into the rabbit hole and if I really wanted a working steam engine should have made one from real plans.I would have preferred to re make the crosshead cylinder but had no material to do so which is why the extenders came about.What I really should have done was use the piston rod as the standard and turn the piston and crosshead slide on it which probably would have made them concentric.I may revisit these parts once some suitable scrap falls my way.

Made a Scribe today:

Made a Carbide tipped scribe today for my Mitutoyo height gage. Used a Carbide blank from a brazed tool bit. Should have chosen a blank a tad wider s**t. Didn’t clean up on the sides…oh well. Was concerned about grinding the Carbide on my Accu Finish machine and taking all day. So I used a small blank…too small. The carbide actual ground down very fast. Used 80% silver solider, worked great.

Thanks Ken for trying

Fine Tuning the Scribe:
I had about 3 tenths error on the bottom of the scribe I made yesterday. I thought was pretty good for an Accu Finish grind. And I could have been happy with that…but. Had a few ideas to make the bottom flat, parallel and with a good finish. The pic shows the first idea with a diamond coated stone thing. First I checked the stone thing for parallel…not bad. So what the hell, I went for it. Lightly brought down the scribe onto the stone thing and gave the height gage not the stone thing about 40 strokes. WOW and WOW again. The carbide scribe bottom is now flat, parallel, with an excellent finish and no more error.

My son started building electric guitars. He needed a way to accurately radius the fret board. A 12 inch radius.
We thought about building a jig that used the rotary table on the mill, but decided a stand alone unit would be beter.
We made two sets of quadrants with a 12 inch radius from some scrap 1/2 inch polyethylene Then a simple base and slide for the router. The slide has 1/8th plexi to guide a bushing on the base of the router.
Mount the neck, then go back and forth with the router indexing the cut to form the radius.

After seeing a build by Stefan Gotteswinter on his channel I blatantly stole some of his design and built a carbide hone.
Sorry no photos of the build, my camera phone died.
Recycled a small 1800 rpm motor from the tilting mechanism in a hospital bed. Cut away the gearbox and matted a pulley to the 1/4 gear it had for a shaft. The disk spins at 500 rpm, speed stollen from Accu-Finish.
The disks came from China via Aliexpress 800,1000 and 2000 grit at about $1.50 each plus shipping.
The aluminum backing plate has a centering hub, two drive pins and two magnets to secure the disks. Interestingly I epoxied the magnets in, the epoxy expanded as it cured, had to grind the magnets down to sit flush.
Leaves a near mirror like finish on carbide, photo doesn't show it on the old insert I tired.

I completely half assed this idea a few months ago while scraping. I absolutely plan on finishing the slow speed grinder to much the same design. I follow Stefan on several platforms. His work is out of this world. But I do miss his older video styles with tool builds. I made his squareness comparator as one of my first major shop projects. Still use it!

I don't recall who, or how long ago it was posted, but someone here or there made a slide hammer with "vice gripes" on them. They used it to pull nails out of corrugated tin.
Fast forward to today, while pulling up carpet tack strips, I needed to pull a few nails out of corners and door jambs.
So, a discarded 3# dumbbell, a 1/4" rod, a little welding, and some  sacrificed vice grip pliers took care of the problem!(https://uploads.tapatalk-cdn.com/20200122/b917abd12295573ac5a0d4da0f05ea73.jpg)

I saw that idea about 50 years ago. Ever since then, it’s been in the back of my mind to make one LOL! I can’t count all of the sliding body hammers that I have collected through the years thinking “that would make a great vise grip puller”. I just can’t get around to welding one up. You can’t see me but I’m shaking my head right now LOL. I guess I’ll just keep thinking about it along with the hundreds of other projects.

So after many years of just thinking about it. I finally got around to making a grinding holder for 1/8” round tool bit stock. What helped was I found my square holding 5C collets that were buried in a pile of crap, LOL. Easy enough just drill and ream a 0.126” hole in the end of some 3/8” square stock. Circuit board drill bits today are usually carbide and the shanks are also usually carbide (but not always). When the bits break I save the shanks and use them for small tool bit stock. So over to the Accu-Finish and in just a few minutes I was done. My first bit with the grinding holder I made was a 45° chamfering bit.

A quick shop project.
Found this old desk lamp in the dump. The cast iron base and neck were really rusty. Sand blasted the base and wire wheeled the neck. The brass shade had a couple of good sized dents, used a leather welding glove as a backer and worked them out. Wanted to polish it but the surface was too pitted from the original drawing process, so it got powder coated along with the base and neck. Replaced the original tattered cloth cord and we have a lamp.
Now need to build a desk for it. lol

Gonna be nice tomorrow so were going shooting. Made a bunch of these Down n dirty S-hooks
(vs just going to the hardware store ) to hang steel target.    I use lengths of scrap wire rather than the chains. 
Shoot em up and throw em out.

Playing around with 4th axis riser designs in CAD today.
I  bought a 6” chunk of aluminum awhile back intended to mount to the 9” Troyke RT
Still cant decide which dovetail size to use the darn things are so pricey.   If the hole patterns don’t conflict I’ll drill and tap it for my baby 3” 3-jaw as well.

Been building these security screens for my patio. (why there are no binocular updates of late)
Yesterday I cut the steel for one of the door frames (blue)
I spent heaps of time ensuring the cuts were square, all the corners were set up square as they were welded, all twist removed and all felt good.
Then I placed it in position just to see.
Arghhhhhhhhhhh, I had cut the vertical lengths 200mm too short.
Obviously I cant read a tape measure.
They should have been 15mm short of 2200, ie 2185, 
I cut them 15 mm short of 2000 ie 1985, dork. 
todays job is letting in two 200mm sections and quadruple checking I dont make the same screw up.
Others maybe but not this one..

That burning sensation you feel is regret... And should subside after 2-4 trams...



Roughed out my new solid tool post riser. 4140. 1/2" 4 flute hssco rougher. .500" doc, 900 rpm, 6 ipm. Ran really well actually. Motor was struggling at first, changed down to the slowest pulley to get 900rpm, and slowed the feed slightly. Ran fine. Always a battle to keep coolant on the table... Little rubber diverters all over to push the coolant onto the sump instead of over the edge.
I'd like to surface grind this, but I feel setting up the angles will be more work than desirable.
No, I didn't need to run a .500" doc, but I wanted to. So, ya...!

Let the fun begin
normally I’d grab a different tool with insert but Shawn got me wondering so today we’ll see how the brazed bit does facing this aluminum.   Not even sure a 60 deg is the right tool but whatever.  At 6” dia the sfm will vary quite a bit from start to finish which may affect the finish.   Going to brush face with a very light coat of tap magic.

Pilot hole.  Going to bore backside to 1.000 which is the hole in RT.
Figure I do the bore true to the OD while its chucked.  Although its completely unnecessary I’m going to 3D profile the opposite side on the Tormach just for fun because that’s really the point.     Cutting the cone taper on the front side on the lathe would be too easy right.

when i lifted the head back up to zero on the dial last night, i just eyeballed it on the scale on the back of the head. turns out i set it with in .002", lol.
so tramming it back in was pretty easy. trammed it to the flats on the vise rather than the table. got it within .0002" side to side. but discovered the head nods .0015" over the 5" circle i was sweeping... thats less than desirable. i have no control over nod. the nod would be coming from the column and the flange base of the column.
when i got the mill and took it all apart, i did take the column out and took the column flange off to clean out the sump in the base of the mill. at that point in time, i had no idea on how crucial those mating surfaces are and just bolted everything back together. maybe once the machine shop is in the new shop ill pull the head and column off again with a crane or something and inspect those surfaces and realign. i could also Moglice epoxy between the column flange and the mill base after tramming....

anyways, thats my rambling for the night....

damn, just lost the post, I guess it timed out.
So here it is w/out the full text, shortened.
scribed the jaw on the lathe, for reference. Drilled the chuck using carbide bit. should have drilled a little deeper on 2 of them.
Was not happy with the results after, but tried it when I got home today, and I'm less than 1.5 thou out, so I am happy.

ya, i really should grind my 3 jaw too... i do like using it, its convenient, but my goodness its bell mouthed... the main reason i dont use it very much. i change chucks probably 3 or 4 times a job on the lathe. between the 3 jaw when something is small and doesnt matter, 4 jaw when something is bigger and needs to be true, and collet chuck when im turning bar stock. all have varying run out. i imagine if i grind the jaws of my 3 jaw, it should then be the most accurate chuck.
i really dont have much to grind with tho... cobbling a dremel (or the hand held wand thingy) in the tool post...

your 4 jaw will always be the most accurate.
My 3 jaw's scroll is worn, and that's where I am also seeing the problem.
It's a really old cushman, probably from the time of the lathe as well.. War time.  I think that's why I was not happy with it at first.


The 4 jaw will not hold a hex, so you always need a 3 jaw. And sometimes my 4 jaw is too finicky. I blame that on the size and design.  I think a much bigger 4 jaw would be smoother to adjust. mine is not smooth, it jerks when loosening and tightening, the screws follow the jaws. On many the screws stay in place.


If I get a new 3 jaw, I would like it to be with screw on jaws, so I can reverse them easily. But I don't see that on 5 inch chucks, only 6". And I think 6" might be too big for my 9" lathe.

Moving setup from lathe over to mill for front side ops.  Holding in the 4-jaw on sq sub plate mounted in vise.
 Need to remove vise jaws to fit and also fab up some copper soft jaw covers ti help reduce marking on the finish diameter.   I think the copper may actually still mark the AL but its got to be better than the hard ateel jaws...
And usual x y zeroing on the coax.

I wasn't either till I bought it. turns out I used to live 2 miles from the manufacturer.
it old, no parts avail. Apparently they make some very high end stuff.
I took the spindle apart when I got it cleaned her up, and rebathed her in fresh oil.  She liked it.


She's very small and is really made for inside grinding, but not deep inside grinding. I wish I had a more versatile one. I used it to grind a shaft before lapping.  It did what I needed.. but it's tough when you can't use larger wheels, and only use points.

Soooo, yesterday, see above, I made a heat treated 1144 part. Today I used it as a file stop thing (below pics). I wanted a nice full radius on the end of my project. With the help of the hardened 1144 part. It was very easy to keep filing, until the file zinged across, telling me that I had completed the radius. The hardened 1144 part stopped me from filing anymore so it controlled the form and dimension of the radius. Was a little more effort to do it this way, but I like the results.

How do you heat the parts and know the temp?   Color or you have a little furnace ?

I have heated treated 1144 for so long that I have learned the color. You can also use a magnet. When the magnet stops sticking to the metal. Then you have reached the proper temperature for quenching.

I suppose it could dull a file if you didn’t pay attention. But I stop using the file at the first notice of zinging. Then I finish up the last few tenths with a stone for a better finish.

31" high, 24" lexan screen, 7" gap under for handing items across. Frame is stainless. Needed fiber or nylon washers for fastening the lexan, I can't go to home Depot and my supplier couldn't get any in a reasonable time frame, I had to make them myself. 45 .100" thick nylon washers, that was boring work...

But the pharmacy employees are very happy. They feel much better now. Stayed up till 4am getting everything done.

I didn't make a post for my solid tool post project, I just keep adding updates all over the place...
Jeff, yes I copied Robin. Cept his is cast iron. I will probably do the L bracket Stefan gotteswinter did as I do move the tool post around to suit an awkward cut.

I made these cute little t nuts tonight and hardened them... Then goofed up real bad....

When I built the original cobbled together tool post back when I took my compound off to scrape, I just lined the bolt holes up with how I had the compound setup at the time - which was in line with the center pivot pin. The slot the t nuts are installed is just a wee tad south of in line with the pin... i just copied the same design on this solid post... Well, fiddlesticks... My first real goof/damage I've caused one of my machines... An apprentice mark, an idiot chip, a "go to the office and see about the long weight"... I feel ashamed, I will fade backwards through the bushes back into the shadows where I belong....  :03:

I'm obviously going to need to modify my design to get that bolt away from there... I will likely make it a 3 bolt hold down at 120° increments. And I'll have to plug up that 'for shame' hole to forever be a reminder of my blunder....

Setting up both solid post and compound with the t-nuts with some sort of quicker disconnect to switch back and forth.

I just still need to finish scraping the compound. I haven't finished the gib yet.

Almost like the D1 cam lock lathe chuck mount. Fancy. I'm sure certainly expensive. But I suppose I'll see how much time off I have in the coming weeks... Might wind up with a lot of spare time to make neat stuff

They make top blocks already set up with the studs mounted that fit the bases.  Again $$ but good to get ideas from to copy.   Thats why I decided to make my own riser for my 4th axis rotary.  They get like $750 for the thing

The "Brute" is my old lady of 38 years. She earned that name by the sheer number of cars, lawnmowers and vacuum cleaners she has crashed, burned out and killed in our time together. Don't get me wrong, any woman that would put up with me as long as she has got a pass. She keeps me on my toes. Kind of like the lottery, Some days you win and most days you lose. 
  She has never failed to defend me. On the other hand in privet, she has never failed to jump my ass if she feels she is right.
  All things considered, I'm lucky to have her. And if I make fun of her from time to time it's only 'cause  I love her.

Made the indicator clamp for the tool post. 4140, hardened and ground. I love the ground and black scale contrast. I'll replace the cap screw with a knob next time. But it works, solid. The fit isn't stellar because of the way I sanded/polished the 5/8 drill rod. I might remake the upper post and not sand it. The bore is 5/8 reamed.
I'd really like to try a real Noga arm...

Riser done and test mounted to RT.   Gives ample clearance for the holder, spindle and chuck key tightening.   Now for a tail stock of some sort.  I contemplated leaving the vise on the right side to act as a counterweight seeing as how the rotab setup weighs like 60 lbs.  I worry about the levering on the ways and gibs from the overhung weight off to one side.

nice, I like what you did. I like that toe clamp too.  The material under that, plastic, spring steel? Will it mar the table that much?

I was also going to comment on the nice toe clamp.

Lol, Paul does all this work to build a chuck mount and we're all ogling the toe clamp.

Nice work!

Those little joggle strap clamps do come in handy.  small pc of banding strap is just an attempt at minimizing marking the table. 
Ah the luxuries of putzing around with hobby machining.  Wiping and oiling stuff cuz God forbid anything would look like I actually use it LOL. 
Shawn have you tried the magnetic type noga holders?  I saw the tool post holder clamp which should be nice and solid but wasn’t sure how it affixed to the tool post.   Is the 5/8 rod threaded in?
Title: Re: What Did You Do Today
Post by: Carpenter84 on April 02, 2020, 02:06:34 PM
Yes, it's threaded in.

Are you talking about a normal mag base? I have 4 or 5 of them. But because my lathe is smaller, it's actually difficult to find a spot to plop the mag base and still have a good ready to the top of the chuck. I've tried indicating the 9 o'clock position on the chuck but I can't seem to make it a habit. Nor are my bed way vee's big enough to pirch a mag base.

Ok so basically a drill and tapped hole from the top on the tool post stud.  That works.   
Ya I was thinking just the regular mag base the Noga comes with.   I know what you’re saying about finding a nice magnety flat surface.  For dialing in work on 4-jaw I made a pc of 1/2” sq stock with a tapped hole to mount a regular plunger dial indicator to and hold it in one of the QC tool holders.  Its set on center.  Most of the time tho im too lazy to set all that up and end up just using the mag base on the flat spot on rear ways.

yep, I made an aluminum holder 6061 for that, so I wouldn't have to use my more valuable holders.

I considered the tool holder indicator ages ago, and actually previously had a smaller Noga rip off arm attached to one of my tool holders, but I rarely used it because it was a nuisance. And it also seems I never have enough tool holders - If I put an indicator in one, you can bet I'll wind up taking it out to put a cutting tool in it. Lol.
Because I can't seem to nail down a set of cutting tools i like that work well, I'm always switching to something different.

I have two Noga rip off arms, a red one and this yellow one. I never use the red one because it has a smaller stem hole, I always use the yellow one with the mag base. So, the plan is to make the red one the dedicated lathe indicator arm and the yellow will go back on the mag base (the yellow one in the picture was just for show.) Both arms have the same M8-1.25 mounting thread, so they're interchangable.

(Woodchucker)Exactly.   Ive also seen some pretty elaborate ones being made even to the extent of making a half circle cutout pocket for the indicator.  Never saw the point of all that extra complexity but hey its fun to make and looks neat!!  I’ll normally shy away from the China tooling stuff but this would be a perfect application to roll with a $20 shars knockoff holder vs a $65 Aloris.

got news for you, the chineese knock off axa holders I get from cdco have been pretty good, except for the knurled nuts. But I'm okay with that.

No argument there.  Some of it is quite good for what you pay,  In general I still try to avoid it but sometimes it makes sense is all.  The Aloris stuff is definitely pricey. .
That said I just ordered a bunch of chinese drill chucks.   Again nuthing wrong going with least cost fit for purpose option.
