As others have pointed outed out, casting is often done with wooden blanks, sand and ceramic crucibles even today.
If you can chip stone tools you can use them to shape and finish soft metal.
Metal has the wonderful property that you can change it's properies with just heat, chemicals and a hammer. So you can work it when soft and then harden it to take an edge sharp enough to cut other metal.
With basic metal working in a forge, casting, filing, hammering, riveting or grinding with stone, you can make a lathe.
The lathe is known as at the king of machine tools for a reason. With a lathe you can you can do turning, facing, boring, threading and milling operations on metal.
Et voilà! You have a machine that can make other more specialised machines from "nothing".
- germinalphrase 4y agoNow, where’s the video where we see a lathe made from rocks to a threaded bolt? Give the people what they want.
- Lio 4y agoHaha, yes! I'd love to see that too. Making workshop tools yourself that you get to use later is both really both really fun and a great way to learn things along the way ...even if it seems you can almost always buy the tool cheaper online. There should be some kind of makefile for all the bits you need to make a lathe.

Disclaimer: while I've owned the lathe book for decades, I've been too intimidated by the "go to a junk yard and pick through for scrap meeting these criteria", including a couple diesel piston heads as I recall, to ever start.
