I hate to burst your bubble, MR. S, but I'd be interested to see just how close this carpenter gets to exactly 51.9 degrees! Maybe he'll be spot-on, but when I do prints for my job (not carpentry, however), the tolerance on an angle is generally at least +/-1/2 degree. I'm sure he'll shoot for 52, or maybe 50. Not knowing what this is for, I could be totally wrong - my only real experience with carpenters has been while building our log house, which in itself is inherently inaccurate. Sort of an eye opener for a couple of M.E.s. A nice stick-built with nice square corners everywhere would have fit the profile better.

Let us know!
