The Neck Joint -- Shaping the Mortise
|How deep is the mortise? How wide is it?
I've been using a 30mm Forstner bit to shape the mortise on the body. Remember --
this is going to be a glue-in neck so the mortise is very important for a proper neck fit.
Using a piece of scrap mahogany (from the body cutout), I tested the bits and set the depth on my drillpress. Remember -- practice on scrap.
This maneuver takes a centerline -- as earlier stated, the centerline is critical here. The centerline will determine where the 30mm holes are drilled.
|Starting at the back and working forward, I drilled the first hole. Like a Gibson, the bottom of the mortise is level from back to front. I drilled hole after hole, all to the same depth. The result is a good-looking mortise, the needed little more than some clean-up with sandpaper and a small Microplane rasp.|

is straight along the sides!
You can see the "bevel" or "relief" on the right side of the mortise.
