multimachine Pat Delany's Designs for Low Cost DIY Machine Tools


We have covered septuagenarian Palestine, TX, resident Pat Delany’s DIY multimachine, which is mostly built from recycled auto parts, before. Following on the success of that design, Pat has branched out, researching and promulgating three more simple build-it-yourself tool designs: A treadle-powered electrical generator, a simple compound lever drill press, and—most interesting to me—a lathe made from cast concrete and aligned with wedges sawn flush after the concrete has set up. Engineering for Change has a good overview of the story and the available online resources. [Thanks, Jake!]
