Ok Del.. lets see if I understand the essence of the points in your reply
correctly then...
<p>You saying the following..??
<p>1: Compression crowning a board is basically synonymous with or
at least necessitates "fiber compression damage"
<br>2: F<font color="#000000">iber compression damage will probably
have little effect, if any, on the panels performance as a diaphragm in
a rib crowned sound board assembly.</font>
<br>3:<font color="#000000"> It is not the compression damage per
se that causes the loss of tone performance, it is the loss of crown in
the sound board assembly (the loss of stiffness) that results from that
compression damage that causes the loss of tone performance.</font>
<br>4 The<font color="#000000"> across grain compression strength
</font>that maintains crown in compression crowned boards is inherently
weak and will dissipate over time. (relatively short ??) (regardless of
such factors like such as climate ??)
<p>I am not quite sure why a compression board is said to be "damaged"
(fiber compression damage) when in essence this damage is meaningless in
as much as all one has to do is re-rib and reconfigure for a rib crowned
assembly.
<br>
<p>Thanks for your informative reply

of humour in our discussions from time to time..... well indeed, I do apologize.</font>
