The Birth of Precision Design and Manufacturing in Revolutionary New England

Boxborough Town Hall 29 Middle Road, Boxborough

There was a second revolution brewing in New England in the late 1700s, America’s own Industrial Revolution. The Boxborough Historical Society is proud to present Boxborough’s Jim Gorman discussing the early efforts of New England craftsmen to develop a system of interchangeable parts production that would sweep the world by the late 19th century. Jim is an Aerospace Engineer with deep interest in precision manufacturing. While most histories trace New England innovations in firearms, this early manufacturing story is really more about clockmaking and shoemaking, and does not encompass firearms until after 1810. The presentation will be followed by a brief annual meeting
