Quickly find the curvature of a fingerboard or bridge with these sets of radius gauges.
Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape — a mistake that's easy to make and hard to fix.
Guitars commonly have a "compound radius," meaning the curvature changes from the nut to the end of the fingerboard. "Eyeballing" this subtle change is next to impossible; that's why a set of radius gauges is essential. Also use them for profiling an acoustic bridge saddle and setting the string heights on an electric guitar bridge. Our gauges have precision laser-cut 7-1/4", 9-1/2", 10", 12", 14", 15", 16" and 20" radii.
