hey Gerry  and Jerry.....

depends on the 1750 motor   2 flats can be used also...  and milling the 
flats is better than grinding.. balance is important.  I had a formula for 
the flat measurements but cant find it...   check the List archives from 
about 3 yrs ago it may be found there..

as far as finding motors, Herbach and Rademan  ( spelling??) has a wide 
variety to choose from and they are affordable too...  quick delivery too.
