In preparation for doing the top bracing I built the jig mentioned here:

It is noted that this is a left handed version, so I reversed all of the pieces to make a right handed jig.
1/4" Teak plywood was on hand, and worked nicely - I opted for 10-32 brass screw with a knurled brass thumbscrew - why not.
My razor saws are not deep enough to allow me to cut the full joint depth while using the jig - I am able to set an accurate angle, and cut to about 1/3 the final depth. In reality its better to finish the cut outside of the jig to enure absolute focus on the cut depth.
