I will be adding steppers to my old round column mill in the near future. I will most likely mount them in a similar fashion to what the DRO PRO kits use. Next step is to source some suitable cogged gears and belts. steppers will be 1200 oz-in. A 2-3:1 ratio should work. Can anyone suggest a source for the belts and gears? For anyone that has done this, I'm all ears for advice and suggestions.
