Mark, BAKE, thanks for the ideas... I can see I don't want to take material out of the plate all the way across, for sure..
So, a small housing at the inner corner, maybe with a couple of steps to maximize strength VS removed material seems right. I want to have a significant surface of the rafter bottom/edge bearing for both downward and outward force.
The max. uplift on this design is 200 lbs, so a lag or a strap is in order, I think.
Any other suggestions or pointers appreciated...
