I will soon be building a shop very similar to the pictures posted by MTF. I plan to use a plate, purlin system with common rafters spiked on. I wish I could add more craftmanship to the rafters really but this seems to be the most practical way and I know this is an authentic way to attatch rafters. My shop is still in the design phases, but I have compiled a timber list and have started cutting beams. I have gotten a little side tracked lately because I bought an old saw mill to hasten the process and it requires a little work.
