Manual machines is a small part of the whole.

Automatic screw machine, Christopher Spencer, 1873;

Production machinery has improved constantly, but there is very little
on a small manual lathe that Oscar Perrigo didn't describe in 1916 in
"Lathe Design", from Lindsay Books.

I'd like to know when and how the vertical milling machine was
developed. I think they evolved from die sinkers and vertical
attachments for horizontal mills. The first Bridgeport is at the
American Precision Museum in Vermont.
