Hi Mike, Looks like a fun project. But,, I dont want to discourage you too much but if you use a Stepper or something to turn the turret you will have to address some issues. The turret has to have air to hold it down while machining. this air is part of a pretty complicated system involving the turret motor,the turret stop it also lifts the turret .also the whole thing has a small amount of regulated pressure to keep the oil and chips out of the carrage. Do you have a set of prints? Not saying it cant be done Im just saying by the time you address all these things it might be easier to replace the air motor.

I have started the retro rebuild process. Warning: the pictures my be disturbing to some machine lovers because of all the missing parts...:) http://www.conesusmachinetool.com/1/post/2012/04/hardinge-hcnc-lathe-rebuildretrofit.html Because of the parts I am missing I am going to try to use a DC motor (as suggest by someone on the IRC) or a stepper motor in place of the missing air motor on the tool changer. I am going to start there. I have the axis motors but not sure if I will use them yet. I can just as easily replace them. I am leaning toward Gecko servo drives so if I go that way I will probably replace them because of the voltage limit on those drives. I need a spindle motor. I have a PacSci AC servo motor (1.35KW) and drive. I have not run the numbers to see if it would be a good choice. My gut feeling is that it might be on the small side. If it is I will probably go to a 3phase 3HP with VFD? Not sure what HP it came with. Will build a custom enclosure similar to the mill enclosures I make. I also have the coolant tank and pump and one of the pictures shows a hydraulic panel? I have the over spindle mounted cut off slide? Was that hydraulic? It looks like the collet closer was pneumatic? I will update the blog as I make progress. I appreciate the feedback and help I have gotten so far and hopefully something from this project will benefit others in the future. Oh and of course it will be controlled by LinuxCNC...
