Caption: The Blanchard Lathe
Additional Description: The only surviving Blanchard stock-making replicating “lathe”, built 1822, seen in the Museum at Springfield Armory National Historic Site Thomas Blanchard invented the acentric lathe in 1820, which allowed the standardization and machining of irregular shaped objects.The so-called Blanchard lathe [actually, it’s a shaper since the cutter is a rotating wheel] works much like a modern key-cutting machine with a stock blank [a rough gunstock form] in place of the key blank. The “Blanchard lathe” is one of the great inventions on the road to America’s industrialization.
