Thanks for the advice and your cheat sheet would be welcomed. I just hate to see the wood wasted and would try to design a shed to fit the logs. My plan would be to seal the ends of the logs and store them covered but outside until November when I have time to mill and assemble. I plan to use the white oak as sills and posts while keeping the red oak higher and drier in the building. How will the sapwood do? How much more likely is it to rot?
