I have been doing this and have tried both sandpaper and steel wool on a wooden dowel. The going is slow. I started with paper that was not marked as to the grit then I went and bought 180 and 220 approximately, I can't remember exactly right this moment. Now I'm onto No.1 coarse steel wool. Should I be doing something different? Should I be using some kind of lube with the steel wool? Which is better for this kind of thing paper or wool? This bore was very bad! Thanks for any information offered. Kurt
