I had roughed out a bunch of tenor necks last year-so all I had to do was grab a couple, cut a groove for the carbon fiber rod, epoxy in the rod and take the neck blank to the band saw.
Next I set the table saw blade to cut a depth equal to that of the thickness of the soundboard and then with repeated passes hogged out the recess that will be glued to the soundboard.
To begin the shaping of the neck I use this very sharp draw knife. Does a great job on soft Honduran Mahogany, but take care not to cut too deeply. I sometimes use a spokeshave here, but this is faster.
Final shaping is done with chisel, rasp and scraper. the slots in the side will accept the ends of the insrument sides when finally assembled.
final shaping is done with the bow sander, and now the necks are ready to be glued to the soundboards. I have also made the butt blocks and glued them on.
Once the necks are glued on I need to attach some patches to the area around the sound hole and the center splice just to insure against splitting of the soundboard. I cut them out of very thin maple veneer. 'first you cut out the sound hole, then with scissors the rest is easy.
