Soundboards/stress

[Jim]

Hi Bob:

Thanks for your fine description of your soundboard experiements. The one
where you rolled your standard guage over the convex side of curved board
was very impressive.  If you ever get a chance (time) to do another one,
you might make a panel which is compressed across the grain as the ribs
are glued on. Baldwin does this to avoid putting the convex side of the
board into tension after the ambient air curving of the ribs and board.
It would be interesting to see how your gauge test would be after such
a gluing procedure.

Again, thanks for your thorough work.
