Go read up on the three plate method to manufacture surface plates.
- XorNot 5y agoLearning about the 3-plate method was mind-blowing for me. I hadn't realized how much I was just accepting this huge gap in my knowledge of how we build modern technology, a ton of which centers on "so how do you get an initially flat surface to make a reference from if you don't have one?" Between that, and the lathe, you can build the world.
