Mark Buy Manino's reaming kit, and ream out the bushing and repin to get the right friction. It will take a while, but well worth the effort. You don't need polished pins, but if you've got them, use them. On the other hand, if you're going to sell?this piano, it might be worth it to?replace the h/s/f. Customers who know, would think twice about buying a 30 year S&S with Teflon bushings. The piano will most likely sound and play a lot better with the new parts. ?

Some of the keys are at 80g DW(!), and quite a bit of that excess seems to be in the hammer flanges. So I've gotten the "kit" from Steinway, but now I'd like to hear from the experts on the best way to proceed. My 1972 S&S Service Manual isn't much help ("ream the bushing accordingly", with a target of "3 to 6 grams"). This is one of the later teflon pianos, with the improved (ribbed) bushings. Any takers?? ? Thanks,? ? Mark Dierauf? ? -------------- next part -------------- An HTML attachment was scrubbed...
