If this is the case, the rebound from a very soft blow will not even move the balancier off the drop screw, causing the hammer to bounce. >>I have several pianos with bobbling hammers, especially in the 2nd and 3rd octave. Before doing anything, I want to know what to do. >> I would try repinning the balancier on those notes, reset the spring, and see what happens. I would suspect that the problem is in the arc of the tail and the angle of the back-check. (I like to have the springs as tight as possible without being able to feel the hammer kick upon release from the back-check). Regards, Ed
