This is an adapter for dial indicator ČSN 25 1811 convert it to radius measuring instrument Calculate outside radios for circle. **It is not a accurate scientific tool! (But it works fine for me). BEFORE USE YOU MUST CALCULATE "W" (is the length of the chord defining the base of the arc) with tests on some cylindrical gauge blocks eg This calculator can help you to approach and come close to your "W" (the arc's width) for your adaptor:https://www.mathopenref.com/arcradius.html
