I have 2 questions on the construction of the neck on a neck through bass. The woods i intend to use are zebrawood with a santos mahogany center (where the truss would go) and an ebony fretboard. My first question is concerning the 13 degree angled headstock. How do i accomplish this without a cnc router. Do i buld a jig that is mounted on top of the neck with a 13 degree angle inlcine and feed it through the table saw and then plane it using the same jig to achieve a level thickness? My next question is when I put on the two side body pieces (the wings?) and glue them to the neck I should have to plane it all down (shouldnt I?). How will I be able to do this and have a thickness where the fretboard starts that is greater than the uniform body thickness? Any help would be really appreciated. Thank you guys so much.
