<DIV><STRONG><FONT face=Arial>Hi Arthur,</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>The dryness can cause sticky
keys.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>Think of it as the grain in the wood having less
moisture and shrinking. So the sides of the hole, close
in.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>That is an oversimplification, but it is the
way I understand it. </FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>I couldn't figure it out at first, because I
thought of dampness causing the wood to swell against the pin, and therefore
being tight.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>Mind you that can cause sluggishness as
well.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>Regards,</FONT></STRONG> </DIV>

<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Pianotech,</FONT></DIV>
<DIV><FONT size=2>I have a customer with a Petrof console piano which has many
sticking keys. The piano is 2 years old and was purchased new in
Michigan and moved to Maine. The home is near the ocean, but the
customer does not think her home is very damp because other things made of
wood in the home seem to be very dry. I would like to know if other
Petrof pianos in general have been known to have tight key bushings which
start to stick easily if there is moisture at all in the home.</FONT></DIV>
<DIV><FONT size=2>Thanks,</FONT></DIV>
