I added a bunch of fixes (including some good ideas from Ian) and am ready to make posts to Craigslist.
The Make PDF generator stopped updating several days ago but when they fix it I want to post this notice telling people about the "How to".
Open-source (free) plans for 3 in 1 machine tools (screw cutting metal lathes/mills/drills) are available at http://groups.yahoo.com/group/multimachine/
The machines can be scaled to almost any size, even as big as a railroad car.
They are built using only concrete and scrap steel as materials.
They can be built and aligned by a skilled mechanic with regular mechanic's tools.
They use only long proven but almost forgotten, prize winning, World War One technology. The original machines were built to machine 1450 kg cannon shells.
There is no charge for lathe construction instructions, support or anything else. This is just an effort of one man who wants to help people in developing countries.
