The first step would be to define some paramters.
1. Is the neck to have a seperate fretboard or machined as a one piece then use a skunk stripe on the back.
2. Is the fretboard to have a compound radius?
4. Is the back of the neck symetrical or assymetrical?
Once those are answered, then some dimensions will be needed such as overall length, measurements at certain frets both thickness and width, radii for the back, neck angles, bolt hole placement and some datum point to start from.
Post this info and we will see if we can get this started.
