Blanchard lathe

The first application (1819) was the turning of gunstocks at the Springfield Armory, but the technology was quickly applied to mass production of other irregular forms: shoe lasts, hat blocks, tool handles.
Since a lastmaker could make at least three times more lasts a day with a machine than by hand, it wasn't long before handmade lasts were rare in New England. (Cooper in McGaw 1994:319)
