Sure, all you need is a selection of emory paper, a short wood dowel some LARD oil (very important) and a drill. Cut a slot in the dowel, long enough for a strip of emory wind the paper around the dowel until it is close to the size of the bore and apply oil, turn with a drill. Remember The goal is not massive metal removial! After removing the "line" use 3 or 400 grit paper with lard oil and it will quickly polish us to mirror. NO lard oil and you will get a cross hatch pattern.
