The piano is generally in a studio and rolled out to a stage/gym a few times a year. I don't think I need a heavier hammer... I mocked an Abel Standard hammer on key #33 with a stock weight of 9.1 grams gave me, with a 3/8" lead=11.5 grams on the key, a downweight of about 50 and a 25 gram upweight. The hammer was stock so it needs all the typical trimming which will lower it's weight and lower the downweight and upweight...a lower up weight is not good... I have so many questions...is it so important to lower my R? On the sample the only really bad R was on #16 and #65...which raised my overall R... I haven't tried the shim to lower my R yet... I really appreciate any input... David Ilvedson, RPT Pacifica, CA 94044 -------------- next part -------------- An HTML attachment was scrubbed...
