    Can a CNC not do that for just the mechanical parts?

    (I know way too much about bootstrapping semiconductor production at small scale, which seems to be viable but highly impractical)

      Sure, but it’s not as impressive (imo) when you also need a computer control system, a bunch of circuitry and electronics, and a whole mess of software to make it work in the end. A mill just needs enough spin and it runs exactly as intended.

        Oh yeah, I have a copy of the Gingery books and I love it.

        Gingery never really goes into how much power you need exactly, or what blend of RPM vs. torque is ideal. What would be your guess, since it sounds like you might know?
