Hi Jonathan,
While you are contemplating if you would ever find the time to make me two of these beauties, i am trying to make a detailed drawing in Sketchup which i could share here with your permission.


Would you throw some light on few details please:

-distance from motor shaft center to pulley center? nema 23 yes?
-exact belt length for 30:30 ?
-did you make the 2 holding nuts or buy them?
-thickness of inner and outer race ring of the bearing? It is the 7207 2rs bearing from here yes?
