Hello Isaac: Bushing time can take longer when you start to include everything else like cleaning and polishing. In fact, I usually take some time after a bushing job to level the keys, which means you then must adjust the capstan and check the dip. That does add some time. I prefer to let the wood dry completely too. Sizing the mortises with sizing cauls is not a bad idea either. For polishing the pins I prefer to use "Flitz" if they are bad, a product called "Noxon" if they are not too bad, and if they are very bad, or if some of the plating is missing, I replace them. There is no nice way to clean pins. It's a lousy job but somebody's got to do it. On an action rebuild I generally just replace them. Usually balance pins are drilled through so you can turn the action upside down and punch them out. Insert new ones and secure with a drop of CA glue from the underside. Front rail pins can be pulled using a pair of wire cutters which grip them nicely and a dowel to act as a fulcrum and pry them out.
