lol here ! The armatures I do have the comms.GROUND not turned on a lathe so in order to have that perfect grind (helps eliminate micro brush bounce)one most have true centers on the armature shafts.Centers off bearing inner race.Then comes the balance. They could not make the centers more true! Will they have to take the motor apart? > > Dennis, > > I have drooled over Ken's build many times.
