I can completely relate. I have been studying timber frame building for several years, but have yet to cut my first bent. I do however have the wood for the shed FWW featured thanks to Hurricane Issabel. I had a portable bandsaw mill come and saw my 3000+bf of white/red oak, pine, and maple for about $.30/bf Mine was an ideal situation however since I had used a backhoe to move all 40 logs into easy milling position. My first plan called for chainsaw milling the wood for the frame, but that is a LOT of work. Definitely do-able, but man the aching back! The plans that I'm working from are in Jack Sobon's book "Timber Frame Construction" Amazon link A little scant, but you get the idea. I would find another book for the actual cutting. I think Chappell's book is supposed to be solid:
Timber Framer\'s Workshop link

Books are definitely a good place to start. Check your local library. I have found several around town. From one amateur to another, good luck. While it will be difficult, I'm sure you can do it if you set your mind to it!
