This fixture is used with a router to cut a true flat gluing surface on the top of the headstock block.
Smith's epoxy is applied to the top surface of the headstock block.
After the epoxy cures, this template is clamped onto the neck and used to draw the profile (side view shape)
onto the headstock block.
The headstock profile is sawn out on the bandsaw, resulting in this shape.
The neck is clamped into this fixture, where a router cuts the headstock side surfaces flat and true. These
surfaces, along with the previous index pin holes, are the dimensional references for all of the upcoming
fixtures and machining operations.

The neck blank and headstock block, ready for gluing.
The neck and headstock block are clamped together using wooden cleats and long screws driven into pre-drilled holes in the waste area in the center of the headstock block. The screws are deliberately angled to pull the ends of the fork tightly into the notch.
Here's how the profile of the headstock fits onto the glued up combination of the neck blank and headstock block.
Then, the excess at the side surfaces is sawn away.
Back in the milling machine, the neck is clamped into this fixture. I use a carbide forstner bit to hog out the
wood inside the peghead area of the headstock, drilling down through and stepping in increments.
