Soundboard installation, next topic : the glue

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.

        Yes I has and it depends on where you start.

    I think the point being raised boiled basically down to the degree of
    compression an RC & S board experiences when string bearing leaves
    whatever residual crown ends up being the case. I'm not sure thats been
    quantified by anyone yet... so it might be a nice thing for someone to
    throw into the mix. Leaving 25 % or original crown strikes me as
    introducing fairly significant amounts of compression into the panel.
