This is going to be a through-neck and so the first thing to do is, generally, to sort the neck. 'Sort' means choose the timbers, assemble the laminates, incorporate the neck angle into the blank, calculate the headstock angle, calculate the body depth and the neck depth...
...but you can't calculate the neck depth until you know exactly what the fretboard thickness is. So, actually, that's where I started - by radiusing the ebony fretboard blank using the excellent G&W router jig:
Then fifteen minutes sanding with a sanding block removes the router marks:
So now I can do all the neck calcs and cut the maple/ebony/maple blank:
The neck angle is around 3 degrees, starting from where the top body 'horn' meets the neck, and I generally opt for a 10 degree headstock angle.
