How-To: Mini Metal Lathe

Back in Plastics Month, we featured a simple shop-made plastics extruder built by Instructables user Random_Canadian. Now the arbitrary Canuck returns with this pint-sized metal lathe built with a 14″ piece of precision aluminum T-slot extrusion, and some characteristically resourceful salvage including an electric motor from a cordless weed trimmer, a variable speed switch from a cordless drill, and a tailstock center improvised from a countersink.

The tiny 3-jaw chuck is adjusted with an Allen wrench, and was hand-made by brazing three hex nuts onto a fender washer and running set screws into them. Impressive, clever work.
