Ya, go buy a stepper motor...
The problems would be backlash and power. Even the best (IE, using a 1:40
reduction, with the angle mesured on the imput shaft) would likely put out too
little power. Backlash is the harder one...you could calculate it, but
still...CNC with a non designed machine is not a fun situation. 'real' CNC
machines have ball threads which have 0 backlash. So, if you try, you likely
can do it...give it a go and let me know! I have 2 small lathes (a Perris and a
Busy Bee 6") that would look quite good with CNC on them for $300 or so...
