..... 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

Iíll 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:

That terminal block looks fantastic now. Nice work.

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 whatís to loose, 6 inserts, 80mm (3inĒ) 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.

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...:))

that's a nice facemill pep.


anybody use the little hogger .. I see it's offered by a few places.. seems to be the same design by different companies. I'm thinking of going with http://www.cdcotools.com/index.php version. 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.
