rib.
<BR>
<BR> My question is =
are these
flat laminated pieces cut with a crown in them or are you crowning the =
ribs in a curved caul. I know this was discussed some time back =
but hey
I don't recall it. If they're laminated in a curve aren't they indeed =
more of
a true arched rib (or arched beam) than a solid piece of spruce =
rib
stock with a machine cut curve. In the rib glued in a curve the =
ribs the
grain is indeed in an arch even if it was made thick enough to cut the =
bottom
of the rib flat so as it had more material in the middle than on the =
ends.
With a rib laminated in an arch config. it's also possible to have a =
rib of
uniform dimension (if thats
desireable).<BR> I don't =
know Phil F
got me to thinking about that.<BR> Dale</FONT><FONT =
