This exploded view is of a king post to tie wedged tenon – a wedged king post tenon in a truss frame from a famous meeting house.
The tie is a 12 x 12, and the king post is an 11×12. The through half dovetail tenon is 3″ off the side of the king post and 3″ thick.
It is a half dovetail tenon that was pegged with two 1 3/16″ pegs and wedged with a hardwood wedge from the top.
The wedge taper should be much less (half) than that of the dovetailed tenon. Otherwise, the ends of the mortise would be parallel and thus no dovetail.
“a wedged king post tenon in a truss frame, from a famous meeting house.”
Which famous meeting house??
Thanks, Jack! Will pass your note along to Jim.
I don’t know, any hints?
