I really need to get that book.

In the second, I think I would like to have the corbels carry most of the load. That being said, there is also the point where the principals hit the plate. Im thinking the rafters will have a bearing nose that falls into the housing at the plate and that surface and only that surface should carry any load from the rafter. If that means I need to cut the level cut over the plate 1/4" proud of the plate then so be it. I just would not want any shrinkage or other factors to have that rafter rest on the top of the plate creating some shear forces. Still there seems to be a fact that the rafters (given to bearing points: 1 plate, 2 corbel) there might be some forces trying to pull the joint between principal and arch away from each other. Perhaps the bending of the rafter will negate this. Anybody have thoughts on this?



Thanks
