I turned some Ash pens today and notice that when sanding I get a dark coloring by the bushings. I am assuming that this is a small amount of metal that is coming off with the sand paper and then is amplified by the fact that I use EEE-Ultra Shine which in some cases seems to make the problem worse. Thus far I have turned, rough sanded, dissassembled, cleaned bushings, and the finish sanded and coated. It seems to take of most of the problem. Increases the time by about 50% though,
Is there any other way though? Have any of you experienced the same problem?
