Or skim them down a bit in a lathe. Remember the pulley should be 
slightly barrel-shaped (or the belt will fly off). And that IIRC the 60Hz 
drives take a shorter drive belt than the 50Hz ones (becuase of the 
smaller motor pulley), but you could problably move the motor out far 
enough to deal with that. AFAIK the spindle pulley is the same in all drives.
