Soundboard installation, next topic : the glue

I'm sure there is something amusing there.... be that as is may it would 
be nice with a serious answer to a serious question. I, and no doubt 
several others, would be quite interested to know how to calculate the 
amount of compression that develops in a panel used in an RC&S assembly 
for a given deflection % of unloaded crown.

 Hey Jude.... see what I mean about having to weed through the jungle ?  :)

    Please then, by all means expound.  How much compression is imparted
    into the panel with a typical RC&S design you are working with when
    down
    bearing is applied so as to take the board to with in 75 % of flat...
    i.e. leaving 25 % of original crown.  Take a panel dried to 6.5 %...
    specify the rib radii for a three or four areas of the panel.  How do
    you calculate the degree of compression created ?  This is a point I
    think many of us would benefit from.
