Chad Byrd, I have an electronically dead Nardini 17 x40 in my garage, 20T Fanuc on it. id really be interested in hearing everything you might be willing to tell about your lathes, probably with the exception of the GSK unit. im thinking steppers myself, or finding some DC servos very similar to the ones on my (also electronically dead) 3 axis cnc acra turret mill knee driven, so I can use them across both machines. if anyone else has comments also interested. perhaps send by pm so as not to muck up Archies thread. engine lathe no tool changer. I will be looking primarily at PMDX or the UC controllers.
