FOR TOTAL COMMUTATOR MAINTENANCE

When the commutator is clean and bright all the way around, the grinding is finished and no more copper has been removed than was absolutely necessary. The use of hand stones on any commutator even with large flats (if the stone is twice as long as the width of the flat spot) will not leave the commutator eccentric unless it is already so.
