To under cut the mica on the commutator take piece of hack saw blade grind the set of both side of blade to get width same as mica in the commutator. Under cut the mica by pulling blade outward to allow brushes to touch only commutator. After mica is cut small bevel on each side of each bar . Finish with sand paper not emery
