Great question! A lot of absolute shite in the comments here. If you dream about building a factory then here's my thoughts:
Read
- Read "Faster, Better, Cheaper in the History of Manufacturing" by Christoph Roser - it's an expensive book but gives a great overview of how we got to where we are in manufacturing. From stone tools through bronze casting, Venetian shipbuilders, Josiah Wedgwood, the Portsmouth Block Mill [0] and so on.
- Simon Winchester's "Precision" is a great book too - more concentrated on the emergence of machine tools which will be your BREAD AND BUTTER in a factory.
Steam engines are irrelevant to you but the tools they drove - the lathe, shaper, milling machine are still pretty much exactly the same. Big difference is instead of a man operating them they are CNC.
To know how to make stuff, you need to be able to look at anything and have a rough idea how it's made. What materials, what processes, and then you can figure out why it's done that way. You won't find a piece of solid wood wider than about 3" at Ikea. Why? Because wider wood is massively more expensive than narrow wood.
- Materials: metals, plastics. Wood and glass are a bit niche really.
- Essential machines: the bandsaw, angle grinder, drill press, the lathe, milling machine, angle grinder, tube bender, sheet metal brake.
- Joining metal: Welding, riveting, rivnuts, taps and dies.
- Casting and foundry work, blacksmithing (surprisingly accessible)
I'd say woodworking is a terrible entry into manufacturing. I went that way because it's useful for renovations. But working the wood is a craft, and I wish I'd started with fabrication and machining.
Likewise, very little is 3D printed at scale. It's great for prototyping and looking at things - that's about it. People will argue, but go to any big-box retailer and try to find something that's been 3D printed...
Electronics: You can now build a massive amount of useful consumer electronics without needing to design PCBs. I've built central heating thermostats, wifi-controlled extractor fans, infrared break beams etc. ESP32, ESP8266 platforms are great for playing with. ESPHome is software that makes programming these devices really easy: here's an example of what you can make https://esphome.io/guides/diy - they have a list of devices they support, that's basically a list of industry standard electronics building blocks for you: https://esphome.io/index.html#sensor-components . You'll quickly realise that a lot of electronics is just the same stuff.
I'm out of time so I'm just going to throw references your way:
