- 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":
https://gingerybookstore.com/
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.
- For a more rough and ready, but quite entertaining, version of the DIY CNC (mill however) build there's the sage of Not An Engineer's build of a DIY CNC mill.

- People interested in this might also appreciate this small channel: a no-holds-barred 5 axis machine with expected sub-micron precision. I've learned a lot about what kind of components are available when budget is not an issue (I'll bet this machine will cost 100k by the time it's done).

- I've been following Cylo's Garage for a while. I'm excited to see where he goes. Reminds me of Applied Science meets Tom Lipton, Robin Renzetti, or Dan Gelbart.
- Normally I would assume that a YouTuber claiming to have built a more accurate DIY CNC lathe than Dan Gelbart's was full of shit, especially if he didn't mention Gelbart in the title. But Cylo's Garage is an exception. His objective is diamond-turning optics. So he does need tighter precision than Gelbart's 1μm, and he's been working toward achieving it in an astounding fashion for years—inspired, he tells us in the video, by Gelbart.
This video, though? You know how people say "this meeting could have been an email"? This video could have been a web page. Or an email. It's just a set of slides with a voiceover. Save yourself the time and just read the subtitles:

For reading the subtitles file Building_the_most_accurate_DIY_CNC_lathe_in_the_world-[vEr2CJruwEM].en.vtt, http://canonical.org/~kragen/sw/dev3/devtt.py may be useful.
- Worth noting that the lathe project itself is on indefinite hiatus right now as I understand it, so don't hold your breath waiting to see finished results.

- It's so cool to see Cylo get posted here. I remember finding his channel via an air bearing video years ago and being so impressed at what a (then) kid was doing, cool to see him still doing stuff and getting recognized for it. For anyone enjoying this Dan Gelberts video on his lathe, which I think inspired this, is worth watching. Robin Renzetti also does cool precision focused stuff but I don't know if he does Youtube much anymore.
- Cyrus(creator of Cylo's Garage) written a paper on the diamond lathe design:

Another awesome video on precision engineering resources in the same channel:

- I recently saw another video about a high accuracy 3d positioning stage. The differences and similarities were very interesting. For instance, both used rigid rods with ball joints for accuracy, but wildly different encoders and testing methods.

- It's kind of sad how much knowledge is hidden inside companies.
(I'm assuming something like this was achieved decades ago in certain companies.)

- It would be interesting to see someone use basic hand tools to build up the evolutionary steps towards high end machining or manufacturing machines of all kinds. Sort of a playbook to restart civilization.
