Okay, I didn't fall off the Turnup truck yesterday.... But WTF!???? Dropping bed springs into the engine cylinders to improve engine performance???  Yeah, right.

Ya I've seen that guy before. Really had me going for a bit. He operates a pretty high end car shop, BMW, Mercedes, Bentley, etc

Lol I bit for like 5 seconds then was like wait a second no f n way. 

Today did some genaral shop cleanup and recalibrated my Haimer gage for concentricity and axial zero.   It’s adjustable just like a 4-jaw chuck with teeny opposing set screws.  Used a v block to try and keep everything square and minimize cosine error.
It was actually off by .002 which is in theory well within anything I do but still way more than I’d like for a precision instrument.   Now it’s dead on so I can sleep at night

You clearly have that on a manual mill... Do you find it worth the price over a typical edge finder?? I'm usually good within a few tenths with my 3/8" Starrett edge finder so maybe the Haimer is just faster? With the super added benefit of Z as well? (Which I do not have any solutions for - I use yellow post-it notes to touch off (0.004"))

I do use it primarily for the CNC to quickly set work offsets in xyz.   On a manual mill the Z is probably not useful.   I mounted it in the BP since its easier to rotate the spindle by hand vs in the tormach.   I used to do the slips of paper, wigglers etc but find the 3D gage way faster and easier.   At work I converted several people to the Haimer and they like it.   Lately though we only buy machines with the Renshaw probing system which eliminates the need for the Haimer.    I will say, I can zero my offsets with the Haimer quicker than going thru the stupid probing routines on the Haas control.   For those with only a manual mill it's nice to have but by no means cost effective unless maybe your zeroing stuff X and Y multiple times a day.

Did you say it does not zero in the Z axis? Or is not useful that way?

On a manual mill, unless you have a DRO on Z and also a way to keep track of the tool lengths when in the spindle, there’s no benefit to the Haimer at least in Z.
On a cnc mill, in the control, your tools all have their length recorded in a tool register.   The Haimer is also listed as a tool with a length measured when the dial is at Zero.   By setting your work offset in Z to zero with the Haimer, the control then “knows” where the tip of all your tools are. 
That’s a lot of word salad hope it makes sense.

Ahh that's a good point... Silly me didn't consider the actual tool offsets.
I COULD figure all that out for each tool/holder but that's kind of a lot of work.
Thanks for the insight.

Some kind of retaining cap and bearing spacers.
1045 steel, 5" OD. What I'm assuming is a seal groove in the cap.
0.001" tolerance all around in the bearing spacers. They are surface ground.

Just a simple task today. Rough skimming some bar stock that came from heat treat.
1.50" bars, don't know the material. I'd say they're stress relieved and tempered to about 35-40Rc. Face, center punch, skim to 1.485.
Someone's machine food. I'm doing a few orders worth, about 65 of them. Boring, but pays the bills. It is nice to not have to think sometimes.

Looks like you’re really starting to roll with the jobs incoming.   Good to see.   
I’m working for the man today - making a Swiss cheese fixture plate. 430 holes tapped 1/2-13 in a 1/2” steel plate.   Pushed it to the 20” Y travel limit

I have full time work. Multiple jobs a day, or multi-day jobs.
I just don't usually have time (or think to) take photos and post.


Oh look, lucky you. Making fixture plates on a handy dandy VMC... I keep having to do fixture plates by hand!! Lol.

Quite busy again.
I have a large order for a whole mess of different types of fixtures and clamps.
The photo is just one batch of about a dozen.

Chamfering is always kind of a pain in the butt. And many of my parts drawings require specific edge breaking. I used to chamfer with a die grinder or pencil grinder and carbide burrs but it's really easy to slip and spoil a nice finish. So, I finally wacked something together yesterday. Quickly bolts to the T&C cutter grinder, very easy to adjust position and chamfer size. Dressing the wheel is a bit tricky but I'll sort that out later. The close up picture doesn't do the grind justice, it is decent. But a quick whip with a Scotch Brite wheel and it's baby smooth. And most importantly, it's quick and straight.

I will likely give this to my CNC guy to cut diagonal grooves and send it for hardening. Plates are A2.
