To me this would yield a fairly amount of crown in the rehydrated panel. To achieve this level for sure takes a well set up box & regular monitoring. I meant to say "yield a fairly small amount of crown." Duh!--Dale But pressed into curved cauls. The effect on the soundboard panel is the same as if it were pressed at a somewhat lower MC. Del I'm assumning you're speaking of simply stretching the panel since spruce does seem to have quite an ability to flex across grain. Even so it seems that it would have to be a fairly steep caul to make much difference. Just holding small left over pieces of board in hand and bending them into tight radii to see how much they'll bend before breaking is one of my personal favorite recreational shop sports. We all take turns and keep score & the loser gets to buy lunch. Any one have an idea as to the config. of curved cauls at S&S? Is there anyway to ask It doesn't matter . just curious---Dale ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
