<DIV><FONT face=Arial size=2>I do have a book of his on identification which I
read, not sure if it's what your referring to. I thought you were talking about
the shear forces on a glue joint. Of different types of forces (roll, tear,
shear, impact) I'm making up terms here, I think of shear as being able to
withstand some of the greatest forces. But, I'm no engineer. I'm thinking of a
steady side load over a large flat or quartered glue surface, I can't think of
how that could fail, given proper clamping and glue up. Anyway, I don't have the
facility to manufacture a laminated panel so I'll be staying with solid
construction, as I have been with ribs and bridge caps. But, I will soon
probably make some laminated ribs. Were we talking about panels or ribs? I can't
remember. Hope to see you in Anaheim. Carry on.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi Terry and Jude,</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm following this with interest and think I'm
missing something. I can't for the life of me see any weakness, from a
strictly structural standpoint, of any component being laminated. This, I
would think, would only help to increase stability and uniformity. Unless,
of course the adhesive were faulty. Since we are assuming these components
will not be below the water line or subjected to high heat, almost any
accepted wood glue should be fine. I guess sub freezing temperatures should
be considered. There is such a huge area of glue joint, I can't imagine a
failure, but, I'm intrigued by your concern Jude, I hope you will share some
of your research. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>Maybe there is no need for concern. I
would refer everyone to read Bruce Hoadley's "Understanding Wood" if you
haven't already, and if you have, reread the section on the strength of
wood. There are several entries on horizontal sheer. I would be interested
in any informed statements on its application to laminated ribs and
panels.</STRONG></FONT></DIV>

unto itself; and I was shaking in my boots given the company
(remember my piano was right between Ron N's, Dale Erwin's
