Concave/Convex Radius Gauges For Guitar Repair - Set of 7

Designed by Mark Stutman of Folkway Music, these radius gauges are handy for guitar repair and building. Can be used to identify unknown radiuses on the top and back of instruments, or marking braces before rough profiling. 

CNC-cut from 1/4" baltic birch plywood, with a hole to hang them or tie them together. They're sealed with a light coat of shellac and they're marked clearly so you don't need your OptiVisor to read them. 

Set of 7 includes the following radiuses: 10 ft; 12.5 ft; 15 ft; 20 ft; 25 ft; 35 ft; 45 ft

Note: these work well paired with our convex radius sanding blocks.
