Panel drying and finishing

[David Love]

Wouldn't that then create some problem in terms of the stresses in the panel
if you put a finish on one side, dry the panel down and then glue the ribs
onto a somewhat warped board?

Mostly. The cells on the surface have filled with finish, and 
there is a slight physical constraint there, so it'll be 
straight when the MC is uniformly where it was when the finish 
was applied.
