<DIV><FONT size=3> Hey Gregg</FONT></DIV>
<DIV><FONT size=3> There are no magic formulas just some educated de=
cision
making. I.E. a D board is going to get a thicker panel than a M
board.</FONT></DIV>
<DIV><FONT size=3> And by the way if you had an idea that
all Stwy B boards or L boards were the same thickness from th=
e
factory , forget about it. I've seen B boards as thin as .320 or as thick as=
.370. & both sound fine. However .370 for softer /less dense eastern spr=
uce
might be fine but with the Sitka .340. is enough. This would be the thickest=
part of the panel. </FONT></DIV>
<DIV><FONT size=3> Also choosing panel thickness depends on how much=
compression is going into your system. In a purely CC design there must be s=
ome
thickness/mass to compress. I/E a .300 panel under extreme compression=
would tend to ridge & split sooner than one that was .340. It's a
stregth issue in this case..</FONT></DIV>
<DIV><FONT size=3> However if you are primarily rib crowning one cou=
ld use
a .300 thick panel with no thinning/ diaphramizing & get a good out come=
.
I've done it.</FONT></DIV>
<DIV><FONT size=3> When I order my panels for a B or D my m=
ax
thickness request is .360.</FONT></DIV>
<DIV><FONT size=3> M,L, O can be .320 no problem. That being said I'=
ve
seen lots of things that work & in the case of the B boards (as mentione=
d
) variance in thickness the thin one sounded fabulous but showed =
more
evidence of compression.</FONT></DIV>
<DIV><FONT size=3> It's a judgement call.</FONT></DIV>

was down for a little over 24 hours. Sorry to reply so late. I was questio=
ning
wether there was some formulae that you used to calculate what thickness o=
f
panel you will use based on the species selected. Naturally this also hing=
es
upon what type of panel support you plan i.e. RC&S or CC.
