Just to pickup from a previous post, on the rescue of a disappearing historic structure,, and it's many challenges, I can honestly say, having personally experienced it, I watched the long 45 foot timbers roll in that would become the long mud sills and the upper main plates of a 3 bay barn, to become part of the permanent collection of buildings at UCV
What was really intimidating was the size. especially of the large ends. ( over 40 inches), knowing full well the finished square would only be 12inches, all the remainder waist!
The hewing process was on site, open to public scrutiny, no short cuts allowed!
