Caliper Radius Gauge

This is a "remix" (in the loosest sense of the word: I remodelled it from scratch) of a radius gauge designed by Thyn.

It's a simple tool that attaches to the depth gauge of a standard size (16 mm wide) caliper and allows the measurement of external radii. There are two versions. One is based closely on Thyn's model and you measure the radius by multiplying the caliper measurement by 2.414 (as shown in the debossed text). The other version (shown fitted to the caliper in the photo above) gives a direct radius measurement (i.e. you just read the number on the digital caliper display to get the radius).

You can download the models from printables.com.

I am a hobbyist metalworker and woodworker. I work as an electronic design engineer and spend most of my working days in front of a computer so I enjoy having the opportunity to use my hands and make things in my spare time. I particularly enjoy making tools as I can then use them on other projects. This website showcases some of the things I've made.
