One indication of how far he will go to get what he wants comes at the end of the barrel-making process, when a lead slug is impregnated with polishing compound, fitted to the end of a steel rod, and pulled back and forth through the barrel. This is called lapping and gives the bore a mirror finish. It takes about 1,100 strokes, and just about all barrel makers use a machine for the process. Jarrett's barrel specialist, however, believes that there comes a point when you can "feel" that the job is done. This is only possible when you lap by hand, so that's how they do it to Jarrett barrels, hour after weary hour.
