Abstract:
1. A method for routing a dovetail joint on a guitar shoulder, comprising: (a) determining if the bridge locus on the front face of a guitar body is flat, concave, or convex; (b) determining if the neck angle between the heel and the finger board of a guitar neck deviates from a threshold angle; (c) determining the thickness of the lower portion of the finger board of the guitar neck; (d) determining whether the angle of a dovetail joint on the heel is perpendicular or non-perpendicular to the finger board of the guitar neck; (e) determining the geometry of the finger board and the heel; (f) determining the top drop angle on the guitar body; (g) determining the horizontal position of the shoulder of the guitar body; (h) cutting a finger board pocket on the front face of the guitar body taking into account the geometry of the finger board; (i) cutting a heel pocket on the shoulder of the guitar body taking into account the shape of the bridge portion, the neck angle, the top drop angle, the low spot depth on the shoulder, the finger board thickness, and the geometry of the heel; and, (j) cutting a dovetail joint in the shoulder of the guitar body taking into account the angle of the dovetail joint on the heel.
