Instructables user Random_Canadian turned a power drill and miscellaneous other power tool parts into a functioning mini-metal lathe that can machine copper and aluminium. As assembled the mini-lathe has a three-jaw chuck and a 2-axis tool holder.
The project is a moderately-difficult for hobby makers but once assembled it can help you create other tools. Considering most mini-lathes range from $US400-1000, if you’re interested in machining and don’t have a TechShop handy, this might be a project for you.
