American Precision Museum
The tools and methods that made mass-production possible were pioneered at the Robbins & Lawrence Armory in Windsor, Vermont. By improving upon the latest metal- and wood-cutting technology to achieve a high level of precision machining, the firm became widely known for the quality of its rifles with interchangeable parts. The armory building still stands and has been recognized as an International Mechanical Engineering Heritage site by the American Society of Mechanical Engineers. Housed in this building is the largest collection of historic machine tools in the U.S., covering a period of almost 200 years.

Fun Fact:In 1920, James Hartness of Springfield, Vt., invented the Comparator. It made it possible for machinists to measure a curved shape by comparing its shadow with a chart showing the shape it should be. This allowed for greater accuracy and consistency during the set-up of machine tools, greatly advancing the manufacturing of interchangeable parts.
