Stator plug clearance

After securing the new inner primary to engine locating ring with "Retaining Grade" green Loctite, it is necessary to create clearance for the stator plug. I like to do this after the ring is in place so I can blend the surfaces. Probably not totally necessary and would be very difficult to do without a pencil grinder. In the past I have also put the ring in place, used a carbide tipped scribe to trace the stator plug clearance onto the O.D. of the new ring, and then, using a 4" fender grinder, cut the clearance to the scribe line. Either method is effective.
