Wondering about discrepancies on horizontal shear values. Sobon's house book list EWP #1(beams and stringers) as 65. Then on a another reputable site the listing is 125. This is quite a difference. The 65 seems right but then why would there be so many varying values?
What then is the true value for #1 Northern red oak, and for all #1 red oaks(beams and stringers)?
