A classic manual Bridgeport mill, a foundry for making castings, a heat-treating furnace, a steel planer, a lathe, a drill press, a grinder, and a supply of steel is enough for a master machinist to reproduce all that. That's what was used to make machine tools in the first half of the 20th century.

- how these machining processes can be automatized, and
- how the cost, space requirements and noise levels for these machines can be reduced so that every ambitious maker can have them in their apartment
Voila, the start of a home manufacturing revolution ...
