I have decided to go with what I have on hand , which is a couple of 12v
wiper motors and one HF 18v drill motor . I just ordered another gear cutter
, I'll be able to do stacked reduction gears in a fairly small package now .
These will be 20dp gears , the same as those inside the QC box on my lathe .
Should be robust enough for this .
With PWM motor speed control plus direction control , I can set one
reduction ratio that will be a compromise - mostly on high speed end - that
gives a uniform speed for a decent finish . Which is a lot of what this is
about . I just can't crank precisely enough to do some of the things this
mill is otherwise capable of . Using the boring head or face mill are
perfect examples . A uniform finish is dependent on uniform feed rates .
