Which option do you like better?
I am not certain as I don't fully understand what you are looking at. Before surgery using Chris' method your tenon would have been 3 inches long, 1.25 inches thick and 5 inches wide.

How much tenon do you have left after surgery? I can try to watch Marc's video this weekend, it won't be today. Fv for yellow poplar is 145 psi.
