Re: [CAD_CAM_EDM_DRO] servo vs. treadmill motor

Hi Mark,

Are you replacing the EMCO's spindle motor with a Servo? And will you
be removing the index wheel and sensor? If so, I'd be interested in it
for my Sears/EMCO 5" lathe. Have you found a good way to mount another
encoder? That would work too!
