[pianotech] help needed with Hamilton

[pmc033 at earthlink.net]

Hi, Wim:
    I'm assuming it's an upright.  Maybe somebody strengthened the springs to take care of the ringing notes.  These pianos need very loose pedal adjustments, or they ring.  I don't know exactly why, but they do.  You might just try weakening a few and see if they still ring.

This is a 40 year old Hamilton. 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?
