Generally I use a straight reamer and burnisher .001 smaller than the pin to be inserted. SIze, lube and burnish knuckles. On a S&S last week I eased 4 gr off the friction by brushing and burnishing the knuckles. The knuckle burnisher consists of a strip of wood which has cork (gasket material) glued to it, it was on of the first 'tools' I garnished off the p-techlist when I first came on. A great way to massage in the powdered Teflon. A handy strips of wood are the spacers in Renner USA shanks packages. When going over new shanks the ones with the slightly higher friction can be placed towards the bass end of that shank 'tapered' execution section. Likewise if the Strike Weight were sampled the heavier shanks could also be placed more towards the bass of that particular section. In general, a set will range from 1.6 to 2 gr so it is helpful to have shanks of similar SW adjacent to each other making the total SW more controllable.
