<DIV><FONT size=2></FONT><FONT face=Arial>And this leads me to a =
concept I have
never been at peace with: panel flitch width. Seems that a popular =
target
flitch width is maybe about four inches. I have trouble imagining how a =
number
of narrow flitches would be detrimental to the soundboard. That would =
allow use
of some of this non-optimal-grain-angle wood by resawing to quarter it. =
Now
certainly more work would be involved, but I see that as the only =
downside. Some
may suggest appearance, but I don't see that as an issue - often =
the only
way I can find flitch joints on a subpanel is to look for the =
squared-off
ends - straight grain and consistent color make joints nearly =
invisible. Is
there something else I need to get a grip of to understand =
this?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>FWIW, I most often use 45-degree grain-angle =
(non-nicely
quartered) spruce for rib laminations. I reverse the grain angles from
lamination to lamination like below, thinking this may maximize =
stability. Don't
know this really does anything except make me feel better - but it most
certainly does do that (please don't burst my bubble).</FONT></DIV>
