Now that we’ve got the body done, it’s on to the neck.
I start with pattern grade quarter sawn genuine mahogany. This is a very stable and relatively lightweight wood that has been used successfully in both instruments and furniture. 
The first thing I do is to square it off with a plane, then cut the truss rod channel and the two channels for the graphite reinforcement. Once this is done I cut the profile for the neck and glue on the peghead overlay, in this case, book matched camatillo. My client wanted a slotted peghead so I used a jig I made to cut the appropriate slots. 
After the truss rod and the graphite bars are installed the head stock is inlayed with my logo and the fingerboard prepped. 
In this case the fretboard is bound in rosewood to match the binding on the body.
Now I glue the fingerboard on, being careful to keep it aligned with the neck. After it’s dry I start to profile the neck. As I have mentioned before, I find this easier to do by hand as I can finish the job in about the same time it would take me to set up a CNC.
The final post will be finishing and putting the whole thing together.
