Very cool and informative video. Really neat use of salvaged parts and the guy is intelligent and skilled. However I think he kind of down plays and under estimates the cost of the product and tools he was using and he also mentions the fact that you can buy a lathe (that would almost certainly work better) for a similar price. The big kicker is the other tools. The tools to use and or build this lathe would cost more than the machine itself. I'm going to link you some of the tools you'd want to be able to use this machine effectively (and make it).
This granite block will be the basis for all of your measurements it is extremely flat. You'd probably want to make a stand for it and it is very heavy as well. The 933$ version would be ideal for bigger stuff but maybe you could just make small stuff it's a small lathe anyways so lets say the 235$ version

Mitutoyo Digital Caliper 120$ The waterproof version is better if you intend to use coolant. I think you could use cheaper no name ones for the ones that he built into the machine but you would need one good one.

Range dial indicator (runout gauge). He used one in the video and you'd be using one a lot. 219$

That's just getting started. Now you might be able to find some of this stuff used but I'm not sure if I would trust it. You wouldn't believe how careless people treat tools that cost several hundred dollars. If you did go used I'd try to find someone getting rid of their personal tools, not shop tools.
This isn't to discourage you though. I just want people to realize it's not easy or cheap. I'd start out with a lathe for wood and make stuff on it that doesn't need the tight tolerances.
Check out this guy. https://youtu.be/yCaGW9z4blM
