[CAUT] question

[Richard Brekne]

Hi David.

I suppose crown formation itself is more or less out of the question... 
but then again even a 10 cm long riblet will constrain that breadth of 
panel just as much as any other rib will constrain the same width... yes 
??  If thats so then at the very least it would seem wise to me to make 
some attempt at equalizing the degree of panel compression each new 
riblet will have on the panel with the existing rib structure.  What am 
I missing here ?

Cheers
RicB


        The riblets are too short to have any impact on crown formation
        so drying down the panel is probably meaningless.

    My concern with these has been why there is not advised to dry down
    the panel somewhat prior to installation... or take regard at all to
    panel  MC. Given all the discussion about the effects of rib
    constriction on  climate induced panel change you'd think this would
    be advisable. These  are relatively new devices. It will be
    interesting to see what happens  to the various installations done
    at random climate conditions in the next few years.
