In this design and construction collaboration video series we take a look at some of the mechanical design details of the Rahn Repeat-O-Meter. Be sure to check out John Saunders NYC CNC video that kicks off this cool series. The repeat meter is used to survey flat surfaces and look for local errors. It can also be used to check local flatness but only if it has been calibrated on a known flat surface such as a surface plate that has been surveyed with an autocollimator.
