Garry,

Absolutely not critical.  I've made flats with hand grinders and with
hand files.  however they should be the same depth and equally
spaced so the motor stays in balance.  The balance issue becomes 
more critical at 3600 rpm than at 1800 rpm.

Nah, a machine shop is not needed at all.  just a little care.  if motor
vibrates too much, go back and improve the spacing and depth issues
to correct it.  usually a little vibration doesn't really matter.
