Rediscover Lost Knowledge – The Concrete Lathe
In today's Internet connected world where practically every bit of information seems to be at our fingertips, it's hard to believe that some old and very unique know-how sometimes slips away. Lucien Yeomans, way back in 1915, invented a method to construct the beds of metalworking lathes from concrete instead of cast iron. Pat Delaney, who was trying to come up with a method to build machine tools in developing countries, rediscovered the process and adapted it so it could be used to build The Multimachine, a 12" Swing, MetalLathe/Mill/Drill for about $150.
