I'm not sure how accurate the RPM is on the spindle, that's why I was thinking that having an encoder on there would be the best bet and the timing would have to be dead on. Does anyone have any good examples of CNC lathe threading or do any of the cheaper manufactures of drivers have any examples or information. I'd like to keep this project fairly cheap to show that it can be done on a budget to my instructor. I'll have more info once school starts up on monday and if it is a go for conversion. If it is you guys will see the step by step progress.
