cwries,
I boought "A Timber Framer's Workshop" By Steve Chappell, "Building The Timber Frame House" By edd Benson with James Gruber, and "TImber Frame Construction" By Jack Sobin and Roger Schroeder.
I listed them in the order I'd rank them as to how good they are, but mind you thats only my opinion. "A Timber Framers Workshop" has a fairly broad scope of information from the joinery to the math and caculations for load bearing issues, some simple examples of plans, and the basics of the joinery for each of the typical joints.
I belive all of these publications are available on line.
After reviewing these we went to a "
Timber Frame School" where we were able to put our hands on some of the timber framing tools that are available and see them in use. Probably the most important things we learned at the "
school" were what tools to shop for and the importance of making some template parts to "test fit" the joinery before the real assembly. The
school" we went to was totally worthless for any assistance in general design principles or structural engineering discussions.
Anyone wishing to work on a project is welcome to give me a call you can stay with us, then pay for your training

, then help me build a new barn or something....

... ok you can stay for free, and you don't have to pay to work on a project, ... but you could learn about what it takes to do it from the sawmilling to the final build...
