If there are springs, they may be set unevenly. I've never gone beyond feeling each damper in turn, raising it with a sensitive finger, when setting the bends and whatnot, and sometimes finding something that jumped out at me. << If the tray is out, I have gotten very even results by turning it up side down and shaking it. The underlevers are resting on the springs, so this gives me a total resistance(friction, weight, and spring). If I have two springs set, at either end, it is a simple matter to adjust all the springs in between to allow an even bounce when shaken. I am assuming no serious friction inconsistency, but even then, the sensitive eye will notice errant behavior as the levers move up and down, since the overly tight centers will not move the same as their neighbors. If in the piano, I can feel wire misalignment, but I don't think I can get the springs evenly set by feeling the resistance alone. regards, Ed Foote RPT http://www.uk-piano.org/edfoote/index.html -------------- next part -------------- An HTML attachment was scrubbed...
