Dear List,
 
Referring back to the thread of filing/grinding flats on the rotor to convert
to synchronous, I must have missed something . . . . . how many flats are
needed, do they extend the length of the rotor, and does the thickness of
material removed matter a lot?
Thanks for any info
 
Regards
 
Chris
