Wondering if any other luthiers / guitar builders out there drill their pilots this way to force the neck tight into the pocket. I drill my guitar necks this way, out of habit, but wondered if anyone else does this. Basically if you look at the drawing, I run a 1/8" bit through the body holes and just kiss the neck for a mark. Then use a 3/32" pilot bit to drill the pilots into the neck, but I drill the pilots off-center, tight against the headstock side of the wall of the 1/8" bit mark.
This way, the screw runs into the off-center hole, then pulls the neck into the pocket as it tries to line up the holes back onto center. Seems pretty elementary, but not sure if others do this, or more likely, is not really needed if the neck fit is tight to begin with.
