Like many things, the double-edged sword is a point well taken. I had not been aware of sapwood being so rot-prone
The question of sap and rot aside, suppose you do flatten the joint locations on a round wood frame, as Mo originally suggested, making scribe locations flat...was I thinking correctly about the referenceability issue: the perimeter of a frame needs this, etc, and that round stock makes squaring and plumbing (not to mention scribing depth, etc) somewhat unworkable?
I think Chrysler should name their next small car the Desibu
I'd want a blue one.
