The Wikipedia article on Steiner constructions mentions it, but doesn’t explain it, and the source linked is a book I don’t have. This has come up in a practical project.

      Yes, thank you, me too, hopefully with a loose deadline. It’s an absolute ton of work just for a thing that spins, but something has to do it first if you want to bootstrap back to machines recognisably modern.

      I wonder what scale would be best. Smaller is obviously easier to physically manage, but the catch is that your manufacturing error stays the same while the measurements they’re relative to decrease.
