Multimachine: A $150 Lathe/Mill/Drill made of Concrete and Scrap Metal
Metalworking lathes are necessary to the production of almost everything but are too expensive for rural areas of developing countries. I re-discovered an almost-forgotten World War I concrete machine-tool-making technique that can be used to build inexpensive but accurate tools for use in such areas, as well as in trade schools and shops anywhere.
