I finished mounting AccuRemote scales to my G0704 mill...
I went with the stainless steel version instead of the aluminum ones - hoping they're more accurate over the long term.
Still need to mount something to the quill that I'll be able to read with Yuriy's Android DRO solution. The mill came with a quill DRO but it's self-contained and doesn't appear to have any way I can tap into it.
I mounted everything using Cellular PVC (wood trim replacement) to keep the scales electrically isolated, trying to avoid any ground-loops when I wire everything together to the scale reading interface.

Big progress day!
I got my VFD wired and can now run the mill I picked up. Tried a few different cutters & started getting used to the particulars of the machine. Realized how time consuming making nice quality parts can be using an older machine. My new favorite toy. Made up this little steel test cube by eye. Next time I'll indicate and pay more attention to exact angles.

Nice job and vid... I was going to ask you if your Atlas was a 10" or 12" seeing that nice 3 jaw mounted on it. At the end of the vid you said 10... but, if you don't mind, about that chuck... whatcha got there?
One thing to consider... power your leadscrew with a small variable speed motor, one of the best things I've done and use that feature constantly to bump up or down the feed rate. Not to mention wear and tear on the gears...

Oh that old chuck? I picked that up for $50, cost me $20 in gas. It's a Bison.
I am working on a separate lead screw power feed. That will be a big project if I can pull off what I want to do.

Bison for $70... ya, guess you did ok...
sweet. What size? I'm kinda looking at a Gator 6" EA Series, didn't know if an 8" would be too big...FWIW, a few pics of what I did, might give you an idea?...:
belt loose:
slide the motor down/back (just gravity, no springs hold the belt in tension) to tighten:

Mine is 6", I don't think you would want to goto 8" unless the price was right. Great job on the feed control system. What motor are you using?

6" huh... think that's what I'm looking for then, thanks. Thanks, from the specs that I kept on it (got it from Surplus Supply I think):
Think I saw like 5 of these last week at ebay, this one was on my start page there just now:

Today, I finally got around to making a mold to make bolt buffers for Ruger 10/22 rifles. Sorry...I didn't take a whole ton of pictures between the facing and the completed product because I'd misplaced my phone. Anyway..here's what I've got.
Facing operation...done with my home made fly cutter which takes a 1/2" HSS tool bit. This thing produces mirror finishes on aluminum. I didn't have to do any other finishing on the work piece.
The finished mold. The cavities are 1/4". The locating dowels (3) were made from 1/4" rod with the end slightly deformed in my vise so they would be tight in the holes...put a little bit of green loctite in there as well. The groove along the top to hold the excess liquid rubber is about a 1/2" deep...cut that with a 9/16" end mill....and then 2 x 1/4-20 bolts, some wing nuts, and washers to hold it closed.
And finally, the first batch of buffers.
Oh...almost forgot...made a muzzle brake (more ornamental than anything) for my buddies SKS rifle. Made it out of alum. since he was painting the whole thing flat black anyway.
