Yes, it is definitely a case of sizzling dampers. And their being hard and/or crusty was what I was thinking. How to go about remedying that was what I was looking for and, once again, this listserver has come to the rescue. </FONT></SPAN></DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2>Fortunately this client is a decades old friend, and he is also aware that this is not the result of anything I did. He's aware that piano's require a bit of sorcery once in a while, and "oinking" the dampers sounds like the right solution. And fortunately it's not a difficult procedure. </FONT></SPAN></DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2>Thanks everyone!</FONT></SPAN></DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2>-- Geoff Sykes</FONT></SPAN></DIV> <DIV><SPAN class=203384218-19112006><FONT face=Arial color=#0000ff size=2>-- Assoc.

The quick fix for sizzling dampers is to remove the damper and soften the felt a bit.   It doesn't take much so if you very conservatively scratch the surface of the felt, you should ameliorate the problem.   Roughing up the felt too much will cause leaking dampers. Try it on one or two first to see if that's the problem.   <BR><BR>Good luck, Geoff,<BR><BR>Jim Wilson, RPT<BR>L.A.

The customer was out of town so he left me a key to his studio. He returned the other day and while he is happy with the tuning and the other repair work I completed he mentioned that all the wound strings are now exhibiting a buzz when the damper comes into contact with the played string. Once the damper has completely engaged the buzzing stops and the strings damp correctly. He says it is objectionably noticeable only on the entire wound bass string section of the piano. This is not something that I noticed while I was there so I'm curios as to your thoughts on what could have caused this and what I might be able to do to affect a timely fix. FWIW, he lives a couple of miles from the beach but has a DC de-humidifier installed. The piano also lives in a small, relatively well sealed but otherwise non-climate controlled garage studio.<BR></FONT></FONT><FONT face="Trebuchet MS"> <BR></FONT><FONT size=2><FONT face=Arial>-- Geoff Sykes<BR> -- Assoc.
