Does it feel a lot different when you play with the damper pedal engaged? What about the hammer return springs? What about excess friction from corrosion or parts swelling, you are in Hawaii after all. Might just be weighed off heavy too, have poor leverage or both. I think you have to tread cautiously when looking to lighten the action by taking tension off the damper springs. I've done it but only on pianos where that was clearly the problem-in one case it was actually causing the hammers to bobble. It is a Hamilton. If it's regulated and tuned I'd call that a success.

There are two problems. The action is heavy. Everything is regulated the way it is supposed to be. The only thing I can figure out is that the damper springs are too strong. But that leads me to the second problem. Although each note dampens, there is a general after ring in the whole piano. I can get it to stop by putting my hands on the bass string. What I'm afraid of is if I weaken the damper springs, the after ring will get worse. The damper felts are OK, a little noisy, but nothing unusual. I did have to replace one damper flange because the spring had broken due to rust. Any ideas? Willem (Wim) Blees, RPT Piano Tuner/Technician 94-505 Kealakaa Str.
