If the piano gets too dry the wood will compress into itself and release it's hold on the pins. The article talked about a piano with pins too loose to tune. A Dampp-Chaser was installed and several weeks later, after MANY gallons of water, pins were rock solid.</FONT></SPAN></DIV> <DIV><SPAN class=060304505-13032002><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=060304505-13032002><FONT face=Arial color=#0000ff size=2>Just an idea.</FONT></SPAN></DIV> <DIV><SPAN class=060304505-13032002><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=060304505-13032002><FONT face=Arial color=#0000ff size=2>Greg Casper</FONT></SPAN></DIV> <DIV><SPAN class=060304505-13032002><FONT face=Arial color=#0000ff size=2>San Jose, California</FONT></SPAN></DIV> <BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px"> <DIV class=OutlookMessageHeader dir=ltr align=left><FONT face=Tahoma size=2>-----Original Message-----<BR><B>From:</B> owner-pianotech@ptg.org [mailto:owner-pianotech@ptg.org]<B>On Behalf Of </B>William R.
