Rockler Radius Gauge Set
This set of compact, convenient gauges lets you quickly measure both concave and convex curves. The gauges are especially useful for checking the various diameters along spindle turnings, but they can also determine dowel diameters or help you choose a router bit for routing cove or bullnose moldings. When turning spindles to diameter, the gauge will slip over the turning when you have reached the desired diameter. There is no need to shuffle through a stack of thin metal gauges. All sizes on ours are accessible at once, and each size is clearly marked with a clear, easy-to-read engraving, along with indicator arrows that point to the appropriate diameter. Each tool includes both concave and convex gauges. Made from precision machined aluminum. The indicator ring in the middle rotates to point to the gauge you are using, a convenient safeguard against user error.
