Jon, Thanks, I'm a little concerned about the count. Back of an envelope calculations suggest that by the time I put a countershaft on the Sherline lathe to get useful torque at a low speed it will top out at ~1700 rpm
Andy, I'm planning to copy this person: http://www.grifftek.com/images/sherline_encoder/ I couldn't find a cheaper one in the US. Dave, That was my first thought and a much less expensive method, but I concluded I might need an oscilloscope to get A and B pulses set up correctly and then I might have to think about what to do about debounce and decided an off the shelf solution might just be simpler (less fun?) Thank you for the replies Just to muddy the waters, there is a person posting on the Sherline list that has put together a Pic controlled large (relatively) stepper driven spindle and initial tests suggest that it outperforms the Sherline motor in terms of turning and threading.
