I have plans I purchased and most of the details are on it, however the neck is laid out showing a certain degree cut for the head stock. What I am concerned with (my first build) once I figure out the angle, where do I begin the cut to the neck blank so when the headstock / neck cut gets reversed it fits at the proper spot? and here is a larger image showing a little more detail.. Do I cut it right where the angle starts and it all fits in place? I certainly don't want to experiment on the actual neck blank, I guess I could use some pine but that is a little wasteful.. Thanks so much..
