Been here done that with you before. I suggest you re-read yourself, separate your P's from your Q's and stop dodging questions. You've directly contradicted yourself three times now. And below is the chronical. First its meaningless.. .then there is a direct relationship, then its meaningless again. Obviously we are at a familiar impasse so for my part the issue is closed and clear. Grin... to say that percent of residual crown at string up in a new board is meaningless.... I mean really. Cheers RicB Percent of residual crown is meaningless. Read through the various posts gain. It should be clear. David Love So let me get this straight... You are stating outright, an RC & S board that in unloaded state has known values for rib dimensions andradii and panel compression of basically zipp diddly at glue up MC.... that in this state... the application of a known degree of downward stress (derived from residual crown and the above already knowns) has no direct relationship on how much panel compression results ? Cheers RicB No, I'm not stating that. David Love I dont see the relevance to the question about how much compression gets imparted into the panel when a given RC&S board gets subjected to enough downbearing to reduce its crown to 25 % (or any given amount for that matter)of its original height....which is the subject matter of the last few posts on this thread. Cheers Ric B I can see that you don't. Percent is a meaningless measure of compression in this case. David Love
