The body design is very simple. The idea is to have the soundboard (SB) act like a speaker cone. I drew a 120mm diameter circle and where it touched the centerline, I drew a 80mm diameter circle. To keep it simple, I drew straight lines between (no waist). The center of the large circle is the bridge position. I decided on a 145mm tenor scale length. The 2'x2'x1/2" plywood is for the mold and bending form.
