StewMac Radius Gauges, Notched and Smooth - Set of 6

Quickly find the curvature of a fingerboard or bridge with this set of radius gauges.Use these gauges 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.Notched gauges work with strings on!These come in handy when you want to check a fingerboard without taking the strings off. The notched gauges feature closely-spaced string notches for use near the nut, and wider spacing for use near the body (great for those compound radius fingerboards).Our gauges have precision laser-cut 7-1/4", 9-1/2", 10", 12", 14", 15", 16" and 20" radii.They're made of steel for durability in the busy shop.These gauges work for string spreads and fingerboards up to 3-1/4" (82.55mm) wide.Use them in combination with radiused leveling blocks for professional results.This set includes 6 laser-cut gauges, each with 4 different radii:1 smooth gauge with 7-1/4", 9-1/2", 10" and 12" radii1 smooth gauge with 14", 15", 16" and 20" radii1 close-notched gauge with 7-1/4", 9-1/2", 10" and 12" radii1 close-notched gauge with 14", 15", 16" and 20" radii1 wide-notched gauge with 7-1/4", 9-1/2", 10" and 12" radii1 wide-notched gauge with 14", 15", 16" and 20" radii
