Let me restate the question

I thought Ron answered the question.  You can achieve whatever crown you
want.  The issue of why grain angles are chosen in order to increase or
reduce stiffness in the treble versus the bass area because of the angle of
the bridges relative to the grain is another matter.

Hi John

Keeping the laminations all in same direction is an idea that goes other 
directions then worrying about cracks.

What I was curious about and still havent gotten a straight up answer 
too, is whether or not a laminate board laminated over a curved caul 
with the grain all going in the same direction could achieve the same 
crown and crown support as a ribbed board with ribs going perpendicular 
to the grain.  I.e. the strength of the laminant panel along the grain 
compared to the strength of the ribbed board along the ribs.

Cheers
RicB
