First, which control did you have and where did you sell it and how much did you get out of it?
Secondly, you sold the spindle drive/motor? This was a pretty robust DC motor with encoder on it. Though I believe it required 380v to run. I have a 240 on the way which I believe is built on the same iron as your machine, but with full enclosure and hydraulic Collet closer and hydraulic tailstock. I was planning on going servos. My original control has a missing board and keyboard. Hope to part the rest out to get a few bucks for the retrofit.
Please post pictures of your machine and progress on your conversion.
Yes, I believe you can mount the power supply to one side of the cabinet and your electronics on the other. Done all the time in industrial controls. I suppose much depends on your cabinet. How about some pictures of your cabinet with your components sitting in there for us to see?
