Cutting the Scarf JointI prefer a three-piece neck. It uses less precious wood, and it is easier to get stable wood in the smaller sizes needed for a three-piece.
A scarf joint is a long sloping joint at a shallow angle. This jig allows me to cut it with precision on a table saw. I was cutting and planing it by hand until I saw this jig from Kathy Matsushita; she credits Peter Licis.
By the way, if you were to prefer a one-piece neck, I would be happy to accomodate you.
