Grin.. Ok you two... I really did ask the question seriously. Remembering a discussion from some years back where Del stated in pretty clear text that a carefully removed and de-ribbed old compression damaged board could be re-ribbed as a RC & S board and perform pretty much identically to a brand new panel assembled in the same manner. Then reading a study from one of the departments of the Finnish equivalent of the USFD which shows that wood that is artificially aged in a particular manner... in which the cells are compressed makes certain gains with regards to stiffness and the speed of sound which travels across the grain is higher. I dont mean to literally mush the thing into pulp as Terry puts it. But what would be so wrong about getting it just past the point of the cells elastic limit... and then ribbing the thing. It would seem to me that one advantage of ribbing an old board thats gone through all this already... is that ... well its finished with that. Crowned as an RC & S assembly wouldn't this be as about as stable as they can come ? What am I missing here ? Cheers RicB
