I fail to understand your irritation. I simply asked a question... which you havn't answered but instead respond to with the above. I didnt say there was two opposing positions... I said precisely that I was sure it was me who was confused... but that I saw an apparent contradiction, and asked for a clarification. So much for the "there are no stupid questions" bit. > No. there are not two positions. There is one unified theory of > operation and it contains no contradictions.

Well... as so many times before.... a question you apparently dont like just gets the ridicule treatment and the average querier is left no more the brighter for the asking. I see two apparently contradictory declarations about ribs in different contexts. Sorry that bothers you. But a rib that in one context does not offer any support against downbearing cannot turn around and suddenly offer support just because the context changes. Either the ribs offer some support (in some usual sense of the word) against downbearing or they dont. You've said time and time again they dont. Now you say that ribs in a compression soundboard increase stiffness in the board and do so in the face of increased downbearing. Since increasing stiffness is rather synonymous with providing support in the face of downbearing ... it seems reasonable enough to me to raise the ol confused finger in the air and ask a question. > No one talks about "the panel trying to straighten out the ribs" because it doesn't work that way. Have you ever handled an edge-glued spruce panel? Sure you have.

Makes perfect sense. See how easy that was ?? Coulda been even easier had you said when the initial question was posed.. simply "because the rib, longitudinally, is quite stiff and resists being bent with some vigor. And the soundboard panel, cross-grain, is quite flexible and bend(s) readily" ... and left the rest out. > > Del Gawd... you get so agressive....
