Not to cold  & not too hot but just right.</EM></STRONG></DIV> <DIV><STRONG><EM> To the rest of the discussion about dry down before installation & expanding panels & fit to the rim stuff... it's simply of little concern. The fact is that in a C.C. board will contract & expand after it is glued in & it will be more volitile from a tuning/seasonal point of view tan other types & is born out by our experience.  All other forms of board construction fluctuate as well but much less so.......... But it doesn't have any thing to do with the board expanding & pressing a gainst the case or not.  This is simply a false belief refuted with solid science & practical observation of experiments such as Ron N's & perhaps others. It's amazing to me how commonly held the buttressed arch theory is.....but then again I once thought so myself.  However...I was badly  mis-informed.</EM></STRONG></DIV> <DIV><STRONG><EM>  Regards to all</EM></STRONG></DIV> <DIV><STRONG><EM>  Dale</EM></STRONG></DIV> <DIV>  <FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>        </FONT></DIV> <DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2></FONT> </DIV> <DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2></FONT> </DIV> <DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>Richard, I'm glad you asked that.  I too wonder why.  Once the<BR>        ribs are<BR>        on, I can't rationalize a benefit to taking the board outside of<BR>        the<BR>        normal range of (controlled) workshop humidity for installation<BR>        in the<BR>        piano.  Not that I would be surprised to learn of several good<BR>        reasons<BR>        for doing so.  I hope you get some interesting answers.<BR><BR>        Mike</FONT></DIV></DIV> <DIV></DIV> <DIV> </DIV></FONT><BR><BR><BR><DIV><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">Start the year off right. <A title="http://body.aol.com/fitness/winter-exercise?NCID=aolcmp00300000002489" href="http://body.aol.com/fitness/winter-exercise?NCID=aolcmp00300000002489" target="_blank">Easy ways to stay in shape</A> in the new year. </FONT></DIV></BODY></HTML>
