thanks for this Tim. would that square pin be angled to be pulled at in tension? is the square profile to tighten it in the round hole? would spikes or metal fasteners be just as well? if the big mechanics of this joint work i don't see much work for that pin, other than to keep the brace in place (vandalism). or is there more to this?
the 2 pegs in the plate is from sobon's "tying joints- tie at plate", page 6. others have only 1. would that be enough? that would be fine then for the 4D spacing to the end of the tenon, 2" from the shoulder, though still short of the 4D edge spacing specified in the standard for design document.
is that 2X5X6 tenon reasonable? it looks like plenty holding the frame together to get it stood up, and i don't see the roof going to kansas.
