<DIV><FONT face=Arial>No. Look at the photo of the tapered tail - the one that
you sew the glue line on. Look carefully at the two grain angles. The two outer
skins are parallel and the middle lamination is skewed 15 degrees (I think that
is about right) clockwise.</FONT></DIV>

<DIV><FONT face=Arial>Well, sounds like you know what I did. Yes, in the high
treble we purposely laminated in a fairly tight radius. We did that because the
original rib array - which was dictated that we keep - offered little to zero
support for string bearing. With the panel laminations nearly parallel, it was
pretty much like incorporating a rib directly into the panel.</FONT></DIV>

<DIV>I don't know. Is it? Maybe just a bad glue joint? If you look up on the
Franklin glue web site about wood MC and gluing, you will find that they
recommend that wood be no lower than 6 or 7 percent MC (just going on
recollection - I think it was somewhere around there - no lower for sure). So I
have often wondered about how drying the panel (and ribs????) down to 3.5% MC
prior to rib gluing might affect the integrity of that rib-to-panel glue joint
when using a water-based glue (hot hide, Titebond, Bolduc, etc.). That's another
reason I find more comfort in gluing ribs on at 6 or 6.5% MC (and not drying
ribs).</DIV>

<DIV><FONT face=Arial>Yes. Tapering in the tail. The otherwise 8mm thick panel
was tapered to 5mm at the tail - the center lamination was completely sanded
(planed) away in the very tail.</FONT></DIV>

Do you glue them up flat, I mean, you could glue up a crown with no ribs, like
