According to the introductory video Windsor, Vermont and this armory turned into a gun manufacturing plant is where the American method of manufacturing was born. A need for rifles made quickly led to a method of manufacturing that created interchangeable parts and machines run by water power to speed up the time required to make them.
A subsequent show of this method at the Crystal Palace in London - the first World's Fair - had people convinced that a new age of precision was born.
I know you've heard of Silicon Valley, but before that there was Precision Valley starting in Windsor.
The Precision Museum is one of those small museums that packs a lot into it. The focus is machines that made manufacturing and subsequently life easier for all of our ancestors and us, too.
