Soundboard recrowning and rib re-arching.

Hi David

Think of it this way.  You have two panels.  The first one you just 
bend.  Thats what you have below. The second one you squeeze together so 
that the whole panel is already compressed. Then while keeping it 
comressed, you bend it. 

In the second case, the top cells will try to stretch out from their 
already pre-compressed state alright.. but whether they stretch enough 
to actually become tensioned relative to the panels natural state at its 
ambient RH is another matter.

Cheers

Wouldn't the top cells be stretching outwards and the bottom cells would be compressing.
