I don't use any reamer except when installing a new bushing that has to be reamed a whole bunch. I pick a pin, and I have as good a luck with regular pins as with S&S pins and like the regular because I have big fat fingers that tend to be stiff and awkward so longer pins are easier to handle. All the reasons S&S has to make you buy their pins is mostly sales hype. I remove the pin and check the fit in each bushing. If one is too tight I waller the pin around in that hole until I get the pin t have exactly the same fit and the other side then I repin and check for swing. Teflon wants to be a little snugger than felt, six swings instead of seven. You can get the set of reamers from the supply houses that work quite well indeed. Whatever you do it will have to be done again in a year or two on any performance piano. It is NOT a permanent fix. Going for the perfect fit is a waste of time and energy. Get them to work nicely but be prepared to go back and do them again in a few years even on a home piano. Teflon does NOT have a plastic memory so when you deform teflon it stay deformed so super precision is an exercise in futility because a good hard blow is likely to deform the bushing way way past your precision. I gave that precision stuff years ago when I realized I was wasting my time on my primary concert piano because I had to do some it every year and not always the same ones. Newton
