[pianotech] Odd upright event

I had a similar problem once with a Hamilton. When I pressed the sustain, a few damper levers were hitting the plate in the mid treble section of the piano, creating a clicking sound. 

Unless this was a problem that was ignored in the factory, the reason the dampers levers are hitting the strings is because the distance between the strings and the damper levers is decreased. There are only two reason for this to happen. Either the key bed has moved closer to the string, or the strings have moved closer to the keybed. 

I would suspect the latter, and look for a cracked plate. (I also presume the piano was badly out of tune and 50 or more cents flat.)

Was tuning this story and clark upright the other day and it had an odd
problem.  When the sustain pedal was depressed and just after the dampers
cleared the strings, the bottom of the damper levers near the bass tenor
break contacted the bass strings.  Made a rather awful sound as you can
imagine.  Restricting the movement of the pedal would not have been a good
fix as it would not have allowed the dampers to clear the strings
adequately.  Never seen something like that.  I sent them back to the dealer
to get it resolved as it wasn't something I wanted to invest any significant
amount of time in but I'd be curious as to theories.
