In the late 40s, former math teacher, Bob Edmunds Sr., was fascinated with precision manufacturing, and measurement devices in particular, and founded Edmunds Gages in 1950. Our first products were cylindrical gages – precision components for measuring I.D.s and O.D.s. We still make cylindricals today, and over the years we've been innovators in other gaging technologies as well, including automatic process gaging systems.
