Re: [CAD_CAM_EDM_DRO] virtual hand jive

ON a slight, but only slight, side note,

I build model railroads, and we're constantly needing "turn
this shaft here and make that turn over there".

One solution I've used is to wire two permag motors in parallel
(no power supply). When one motor turns, the other turns more or
less with it. If you put a spur gear based reduction on each one
you'll find they more or less stay in synch, at least well enough
for a manual control.
