I haven't checked the lower brush since I put in the new ones, maybe they 
are wearing equally now.  I'll remove the generator and check the lower 
brush to see if it's wearing the same as the upper.

If it is, then I'll assume that there are bits of abrasive left behind 
eating the brushes.  If this is the case, how would you recommend cleaning 
these off the commutator?
