If you enjoy absurd precision and accuracy, have a look at Dan Gelbart's older videos where he fabricobbles together a custom milling machine and grinder with air bearings that can work parts down to 1 micron. No lapping needed.
I like the idea at least of the late Dave Gingery's books: start with a home-made foundry, progress to a lathe.
I don't think I could suffer the janky gimcrack I would come up with though — I suspect even the bargain Harbor Freight lathes would put mine to shame.
If you want to see a video series of someone making this lathe design from scratch (right from casting aluminum), here it is: https://www.youtube.com/watch?v=LBuUOO3qn30
I was amazed at the accuracy and surface finish he could achieve with homemade parts.

YouTube is now blocked to those of us who use adblockers.
Please provide alternative links.
As a data point, Youtube is still working ok for me (using Firefox and uBlock Origin).
I am also using Firefox with uBlock origin--I am on Linux.
I now see "Ad blockers violate YouTube's Terms of Service".
Interesting. Using Linux here as well.
Sounds like a selective roll out or testing then maybe.
Either way, if/when it rolls out to me that'll be the end of my YouTube use.

Hmm, is it something simple like needing to refresh the uBlock Origin filter list? I've seen that happen before for other stuff, so maybe that's it?

Or, build your own lathe using the harbor freight lathe to make the parts.
I share your sentiment though. It's kept me from starting his series (so far)

Living my dream. I hope I can afford to start doing this some day. I work on small antique machines and would love to cast small replacement parts.
Careful with that lathe Eugene!
