Building the most accurate DIY CNC lathe in the world [video]

For folks who are not familiar w/ machine shops, the lathe is a fundamental tool in a shop, and is the only tool in a shop which can replicate itself --- there is even a book series which uses this conceit, the "Gingery Books":

where Vol. 1 has one setting up an aluminum casting foundry in one's backyard, and Vol. 2 has one using it to make a lathe which is then used to either improve itself or make a better lathe, then one uses it to make the balance of the tools in a machine shop.

Thank you so much!! I have been trying to find this book series for years. I I first heard about it on this or another forum ages ago, but couldn't remember enough specifics to find it.
