Wraps emery cloth on rod tip to form polishing tool. Starts machine and turns wheel to feed rotating polishing rod through barrel. Varies rate of feed according to resistance sensed through wheel. Pushes tow-tipped cleaning rod through polished barrel and sights through bore to inspect finish for defects.
