I would say that there are = only 5 centre pins causing trouble and change them. The same piano next year = only had 6 more and the following year about 9. But I guess that the worst part is = that the entire action was uneven in control and I did not want to change all the = centrepins to even it up when I knew the problem would go away in 3 = months when the humidity dropped.</DIV> <DIV> </DIV> <DIV>Really Kenneth it depends on where you live, conditions the piano = lives in and the humidity variations.  Here in Darwin this morning = the temp was 28C humidity was 92% at 9 AM. It went to 34C with the humidity off = 69% at 3 PM and most people leave there windows open to get the breezes.</DIV> <DIV> </DIV> <DIV>Now if I was living in Newcastle where the MC of timber remains = constant all year around I would agree with you. </DIV> <DIV> </DIV> <DIV>Where do you live ?</DIV> <DIV> </DIV> <DIV> </DIV> <DIV>regards</DIV> <DIV> </DIV> <DIV>Tony Caught<BR>Australia<BR><A href="mailto:caute@bigpond.com">caute@bigpond.com</A><BR></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=kennyfin@jetstream.net = href="mailto:kennyfin@jetstream.net">KENNETH FINLAYSON</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Wednesday, February 12, = 2003 5:24 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> DC</DIV> <DIV><BR></DIV> <DIV><FONT face=Arial size=2>Hi List:</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Time and again I have come across DC = installed in a piano, and I feel the customer has thrown his money away.
