Check out the "Build Your Own Metal Working Shop From Scrap" series
of books by Dave Gingery, offered by Lindsey Books. The series tells
you how to start with scrap (literally0 aluminum, common hardware,
hand tools and a homemade charcoal fired furnace to pour all the
castings to build machine tools. They basically follow the evolution
of machine tools, and the later books build on what has gone before,
ie; the foundery and the lathe are used to make the shaper, etc. The
books are:

1 The Charcoal Foundry
2 The Metal Lathe
3 The Metal Shaper
4 The Milling Machine (a horizontal mill close to what you described)

5 The Drill Press
6 The Dividing Head and Deluxe Accessories (includes change gears and
threading dial for the lathe)

7 Designing and Building the Sheet Metal Brake


These books are fantastic. I plan to follow the procedures to build a
custom lathe for automated production, that will have a spindle bore
of 6". The lathe in book 2 has a 3/4" spindle, but once you
understand what's going on you can design your own. Even if you never
build any of the machines in the books, they are an invaluable
education in how they work.

[Unless you're out in the bush someplace, far from any sources of supply,
and so poverty-stricken that you couldn't buy anything even if you could
find it, actually building things the Gingery way doesn't make a lot of
sense. You'll get much better results more safely by using real refractory
cement instead of ashes, clay and sand, natural gas or propane instead of
charcoal, Petrobond instead of his home-made sand mixture, a silicon
carbide crucible instead of an old cooking pot, and aluminum of a known
alloy instead of random scrap. (And that's just the foundry part). It's
great reading for an armchair enthusiast, but if you want to make parts
instead of hurting yourself and burning down your neighborhood, there are
better ways to approach a lot of this...]
