Thanks for the references, there're a big help.
Thought I should mention why I hope to use bent construction. For the most part I will be alone on this project. There will be a couple weekends with a lot of help but otherwise I'll be chiseling and sawing in the Adirondack boonies by myself. My thinking is that I can get the three bents jointed and assembled on my own and then when help arrives use those "resources" to get the frame erected. Once it's up I hope to be able to do the rest on my own. Make sense??
Looks like the rafter to post joints with be either, housed birdsmouth rafter with through tail (#7 illustration), or step-lap (#10 illustration) from the Graphic Guide. The tie beam in the bents will be joined to the posts with a wedged dovetail below the rafter and intermediate plate joints.
I have no idea yet for the size or number for rafters of the 8/12 pitch roof. Besides the three rafters in the bents I'm thinking two more between each bent for a total of seven (7). I'm thinking collar ties and queen posts in the bents and just collar ties on the extra rafters. What do you think, is this overbuild/under-built?
Metal roof--I had planned on dovetailed purlins every 4 feet. I've been told metal roofs attach every 2 feet. Should I instead use a larger # of small purlins, continuous purlins in notched rafters, plywood, or planking under the metal?
That's enough questions for now, I'd appreciate any help,
Carl
