<DIV dir=ltr>Does this mean that the a compression soundboard =
assembly can
hold crown as long as RH is held at high enough levels to =
sustain
internal compression ? Or do you mean to say that the assembly fail
anyways...perhaps more slowly. ?</DIV>

<DIV dir=ltr><FONT color=#800080 size=2>No. Go to R. Bruce =
Hoadly's
'Understanding Wood' and study the effect of creep and compression-set. =
Wood
fibers that are under compression--regardless of the degree of =
compression--will
continue to go through compression-set. This takes place faster when the =
compression levels are higher and more slowly when the compression =
levels are
lower. </FONT></DIV>

<DIV TYPE="CITE">One other thing... you mentioned somewhere along =
the line I

back... that in a best case scenario for a compression board... the =
sound can
be in some sense better or more powerfull... or something of this =
nature then
in a non compression board..... but that that is of little use because =
it is
so short lived amoung other reasons... or have I mis-understood you
