I started a new neck today. I got a birdseye maple neck blank and 5 (one extra for free) granadilla fretboards from Tonewood Experts. I drew a centerline, not in the center, and then cut the trussrod slot. Then I cutout the neck with my bandsaw.
I used two small nails to align the fret board when gluing it on. I also used radius sanding blocks for clamping on the fretboard. I used titebond II to glue the fretboard. I have set my timer for 2.5 hours. Then I will remove the clamps.
