[USER=2700]@MPN[/USER]: I do have a Dremel tool if you think that could be useful. If so, could you explain that technique again because I was not quite understanding it.
As I am reading each of your comments, I also thought about running the commutator in a lathe and holding up a strip of sandpaper just enough to remove the gunk evenly while truing the shape. Again I am simply trying to put 2-and-2 together but I would like to hear what you think of that idea, if it makes sense.
