Bill....look at the hone pictured in my webpage....cost is around 500K.....Jon takes the original barrels out to as little as .005" in thickness, about 2 pieces of note book paper. It is not rocker science, but it is VERY precise machining which requires significant investment. As the barrel walls become thinner, problems become exponential, it is easy when you have .025" of wall to work with. Try the same methods with .008" and you have big problems.
