R,C&S question JD

[Richard Brekne]

So let me get this straight... You are stating outright, an RC & S board 
that in unloaded state has known values for rib dimensions and radii and 
panel compression of basically zipp diddly at glue up  MC.... that in 
this state... the application of a known degree of downward stress  
(derived from residual crown and the above already knowns) has no direct 
relationship on how much panel compression results ?

    I can see that you don't.  Percent is a meaningless measure of
    compression
    in this case.

    I dont see the relevance to the question about how much compression
    gets
    imparted into the panel when a given RC&S board gets subjected to
    enough
    downbearing to reduce its crown to 25 % (
