This is the real-world “MultiMachine”: an Open Source machine tool made from old engine blocks and scrap metal. Devices like this allow Tech Level C groups/societies to maintain their “good, but limited” manufacturing capabilities.
The designers state that “The MultiMachine is an accurate all-purpose machine tool that can be used as a metal or wood lathe, end mill, horizontal mill, drill press, wood or metal saw or sander, surface grinder and sheet metal “spinner”. It can be built by a mechanic using just common hand tools. For machine construction, electricity can be replaced with “elbow grease” and all the necessary material can come from discarded vehicle parts and steel bar.”
