How much torque do you need?


power the X axis and maybe the Y on my benchtop mill . I have (or have
components to build) controllers and power supplies , can fabricate mounts
and the rest in house . I actually had an 18v HF drill motor all but
mounted , using a PWM controller and a 13.5 volt supply . At the speeds I
need it didn't have enough torque - though I may revisit that setup now that
I can cut gears .

Cogs are cheap as dirt online.


And speaking of cutting gears , how about cutting pulleys for cogged belts
, anybody got experience doing that that they'd like to share ?

David's link looks like a promising start.
