  Your idea with the bench grinder does work.  I have made several from 1/3 
H.P. grinders and simply slid the disc on the shaft with a nut.  It does 
require some shimming to make it run true, but not a big problem.  The motor 
responds well to varible voltage also.

 But I think I actually have the answer, my grinder - a machine made for
 spinning sparking discs! 1/2 HP, 3000 rpm motor (UK has 50Hz mains). 
 Heavy duty bearings - made to take off axis pressure. best of all I can 
 easily remove the protective covers and wheel leaving shaft washers and 
 lock nut - all ready for a disc. I'm fairly sure that I can arrange to have
 at least
 a three  inch clearance between all the (earthed) metal parts and the
