There is even more!
A few passes with the cutter, and a few precise measurements later...
The pickup cavities are 3/4" deep and the control cavity 1-1/2". Fortunately the body is 1-3/4" thick.
No neck pocket yet. That is what template #2 is for.
Another chunk of 3/4" MDF machined from a master. It is registered to the body with a nail and a drill bit. (I also made a few measurements, but it is more fun to pretend I am a little cavalier about the whole thing.)
After making sure the neck pocket is 5/8" deep I can yank the template and this is what we see.
Still need to create the flat-spot and drill the wiring holes, neck screw holes, and string-through holes...but that will be another day.
Oh...and the binding channels. Have I ever told you how much fun that is?
