laminated ribs

[David Love]

I'm not sure what you mean?  The discussion has been about rib crowned and
supported assemblies.  The panel has nothing to do with the calculations on
load support.

Dont mean to butt in on a nice discussion I've been following.. but I 
have a question thats been bothering me ever since the Bluthner 
discussion was up a bit back..

If you have soundboard grain alligned roughly perpendicular to the 
bridge... and assuming for the moment that you are able to create with 
this allignment enough load support for a low tension / low load 
scale....  what are the real demands for cross grain load support ?  And 
is this (can it be ?) independant from the need for cross grain stiffness?

Thanks
