I don't have a table saw to use to cut the face of the headstock at a 15 degree angle from a neck billet so I came up with this jig that allows me to cut the angle accurately using my band saw and the cut is clean enough that only a little touch up with light scraping or sanding is needed before gluing on the headplate.
It's made it from two pieces of scrap wood, two threaded rods, two knobs, and a miter bar. The whole thing is 2' long. The bottom wood plate is 5/8" thick and 5 1/2" wide. I ran it through the thickness sander to get both sides flat and parallel. The top wood piece is 2" by 2 3/4" tall after running it through the thickness sander to true up the sides. It's glued flush to one edge of the lower plate. I ran the assembly through the jointer with the bottom plate against the fence and the side of the top piece over the jointer knives to get a ninety degree angle between the faces. An 18" miter bar is mounted to the underside of the base plate at a 15 degree angle to the side face of the top wood piece. I used the awesome power of math

to lay out the 15 degree angle for the miter bar. The threaded rods with the knobs hold the miter bar to the wood assembly. There is a notch cut into the side face of the upper piece to accommodate the band saw blade before starting the cut.To use, place the miter bar into the miter slot on the band saw from behind the blade and then slide the jig toward the blade until the blade is positioned in the notch in the side face of the jig. Clamp the jointed neck billet onto the jig so that the blade lines up with the cut line. Turn on the band saw and slide the jig+billet into the blade until the end of the headstock cut is reached.
I searched the forum to see if something like this is already here, but didn't find it if it is. I like this jig (fixture?) because it is trivial to set up and use, I get consistent accurate cuts with it, and the cut surface is almost good enough to use as is after the cut. Maybe this will be useful to someone else without a table saw.
