---------------------- multipart/alternative attachment OK all you engineer types. I was repining some hammer flanges today on a Steinway that has been in a practice room. Action parts are Renner. It gets hard play 14+ hours a day. The action was rebuilt 4 years ago. Nearly all of the bushings were quite tight -- most 1 or 2 swings. A few had 3 swings and I was pinning for 4 so since the action had been in the shop (idle) for a couple of weeks, I thought maybe I could just vigorously work the shank a few seconds and it would swing 4. I'd hold the flange and make the hammer swing back and forth fairly forcefully for 5 or 6 seconds and then test it again. In each case the ones that previously would give 3 good swings, now only gave 1. The hammer dropped from horizontal to vertical and stopped dead. What made the bushings get tighter by simply working the flange? I'm stumped! dave _____________________________ David M.
