Question

[Farrell]

And if I'm not mistaken, at least one famous manufacturer dries the panel 
DOWN (yeah, that's more correcter :-) and then glues on FLAT ribs (in a caul 
of some radius.

I have not ever heard of any small shop building pure CC boards with flat 
ribs. Why not? And how can they claim to "not change the design of the 
original masters"?
