It's been a long while getting to this point, but I can start to see the light at the end of the tunnel. This is a 1982 Hardinge TFB that had been involved in an abusive relationship. I rescued it at an auction, completely disassambled, cleaned, painted, ground, scraped, and am finally re-assembling and converting to CNC.
I am just now starting on the electrical cabinet so I hope to make some chips with it before the year end.

More Photos. Paint was PPG Amercoat 2 epoxy primer and PSX700 polysilane topcoat with a lot of bodywork underneath. I picked up a car shelter on sale from Tractor Supply which made a great paint booth and kept the wife from complaining about paint fumes in the house.

And this is the current portion of the project. My goal was to fit everything within the footprint of the original machine so it could still fit through a 36" basement door.
More photos to follow....

Here's a few more I found of indicating the Z ballscrew and scraping the ballnut block to dial it in.

Very nice work! Great idea on the "carport".

Wow. Beautiful.
Makes me want to put it in my living room just to look at.

Thanks guys. I'm not planning on making a garage queen - it will most definitely be put to work.

Finally got the wiring finished up this weekend.
Here's the schematic I created:
And the finished control panel:
The panel is way more crowded that I would like, but the goal was to keep the conversion within the existing footprint of the lathe so it could go through my 32" wide basement door without disassembly. I have crossflow ventilation from the bottom left up to the top right and if I end up with a dead air spot on the bottom right below the servo drives, I can add a small muffin fan below the drives pulling cooler air from the left and pushing it up past the drives towards the vent.
And a small wiring box in the top of the right cabinet to collect all the wiring from the new conduit feedthroughs in the chip tray:

Oh wow, that is so beautiful! I love it when I see a project that has the time & energy invested in it doing things RIGHT! You gotta be very, very proud right now.
I recognize that Hoffman control box...24 x 24? If so I have the same model about half completed for the mill I'm building. Those Hoffmans are great. I have 2 of the larger size server fans on mine; one bottom right with a replaceable filter pulling in & blowing directly on the stepper drives, one upper left blowing out through a louvered vent plate. I bought a cheap DC fan speed controller that comes with a heat sensor which supposedly allows them to run slowly at first with a gradual increase to full 747 takeoff sounding speed if things get really hot. Haven't hooked it up yet though...too busy putzing around with the Acorn/lathe de-Mach'ing project.
