No disclaimer there and yes I used that for a while with less than satisfying results. My point is that unintentional dis- information occurs unfortunately. </BLOCKQUOTE> </BLOCKQUOTE> Now, see? That's just what I mean. Obviously Nick's specification worked for him using his boards, his process and his shop conditions. There was/is enough different in what you were/are doing to make the results less than satisfactory to you. From his perspective it probably wasn't disinformation. </BLOCKQUOTE>   .            Del --My first board was one of Nicks. I should have mentioned that Nicks method apparently didn't work for him any better than for me as I learned from him later that he had incorporated pre-stressing along with the other.Talk about disinformation from a well respected Rebuilder!! I've since forgiven him because all his other good qualitys and contributions."Grin"<BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">     Although prestressing isn't as sceintific as measuring rib height ,tension, beam strength, and resultant angle of deflections for bearing values , it does work. But that's not to say that I'm uniterested in calculating bearing in that manner. I just haven't gotten there yet. I would love to compare the end results using both methods and will. </BLOCKQUOTE> </BLOCKQUOTE> I wasn't suggesting that you should measure all this stuff. But, I'll be you compensate in some manner for it all. Whether you do it consiously or intuitively is another issue.    >>>>>>>>>I was going to say this last night but ran out of gas. Both  I believe. I learned a while back that Ds need real generous amounts of bearing to move a panel this large, When I'm pounding on the bridge and driving in the wedges it;s pretty clear how stiff a particular board is to the tactile sense.         <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">    As a matter of interest to me we both stated we would apply more bearing on the Baldwin system than the factory specs. suggested.
