Soundboard contruction methods

[Richard Brekne]

I think most of us have no problem differentiating between the concepts 
of "bent" and "curved", indeed as John Pattons reply to my post clearly 
shows... along with most of the comments and replies I get.  Terrys 
description below gets a bit murky... but then we all know what he is 
talking about... and he used a whole sentence to qualify the phrase 
"bend a curve".  That said I'm not really certain that laminated form is 
best equated with the word "bend"... even in the context of the 
discussion which was a reply to JD's querry on the matter.  I dare say 
the laminated crowned rib performs more like a machine crowned rib then 
a bent one.

            I "bend a curve" into all my ribs by laminating five to
            seven laminations of Sitka Spruce ranging from about three
            to five millimeters thick. Several small shops are building
            ribs in a similar manner.

    My point was and is that people don't differentiate between a
    rib that was built with a crown in it, and a straight one that
    was pressed into a caul. "Yea, the ribs are curved - we press
    them on the board in a curved caul". Noun or verb?
