All Righty....
I've been meaning to get a post going on this and I thought I better git-r-dun before I got too far into the project.
A little background first....
A couple of years ago, I bought a Clausing Series 100 MK3a lathe. My original intentions were to restore it, but after looking for the correct motor mount and the countershaft assembly for the last two years (don't ask about those parts on ebay that I ....just... missed a few months ago....) I finally decide to CNC it. I know this may really PO some old-timer off, but I want a CNC lathe and this one is going to be it. Plus, I think it might be cool to have a 1940s lathe with 2010 electronics.
With that...on with the build.
Picture 1:
I already started the conversion here. I have my 220v treadmill motor mounted where I want it. It works great with the KB Electronics KBCC-225R motor controller. I now have variable speed control on it. I could not mount the motor where the stock motor was because I took out the countershaft assembly and there was not room through the headstock to run the belt down without first going through the countershaft assy. So...I have it up high and out of the way when I add coolant on this. And...the lathe now gets around 1900 rpm where before it only hit around 800. The headstock has bearings and not babbit bearings so it should handle the new RPMs nicely.
Picture 2:
All the gears and quick change gear box is going. Going on ebay that is....
Picture 3:
Another view of the motor setup. I should note that I am going to build a motor and belt cover once this gets rebuilt. If I don't get it tore down this weekend, then next weekend.
Picture 4:
The original Clausing stand. Not sure if I will reuse this or build a new stand.
Picture 5:
The electronics. The box is an old Gateway 2000 computer case. Yeah...back in the day Gateway had 2000 in their name. You can see the KB controller and the power supply. Still need to clean up the excess wiring. The computer power supply is running four (4) cooling fans in the case. The original power button up front controls it yet. I have the front of the case and the outer case being painted. The case and lathe will be dark red with Carbon Fiber decals over all the aluminum pieces going into this.
Picture 6:
Various bits and pieces that I have collected. Let' see if I can identify them...
Should be about three Compumotor OEM750 drivers. I only need two, but I got a heck of a price on them on ebay. So I bought them all...
I have three Pacific Scientific motors. The big one is a NEMA 42. The other two are NEMA 34. I am using the 42 and the smaller 34 on the build.
To the right are the ball screw mounts for the bed. In the back is the 1.125" Thompson ballscrew.
Lots of wiring, connectors, and other pieces are in the picture too.
I have the ballscrew for the crossfeed on another bench.
Until next time....
