How much pressure do you supply to an air bearing? I would think on a
lathe spindle it would get pushed off center when you start applying a
cutting load and the surfaces would rub. But I guess if you had enough air
pressure...

Oh dear god, they finally found it. THE lathe.
Alex I knew you would find this. I didn't know how long it would take, but
yeah. This lathe is absolutely ridiculous.
I honestly don't think anyone at hack pittsburgh would have any project
needing 1 micron accuracy, but I want this
lathe, bad.
Air bearings though, are doable. They can be machined yourself, but the
tolerences are crazy tight, and they have to be
dead on to work right. If you could do an air bearing spindle for your
lathe, that would be the ultimate- 100,000 RPM and
micro tiny parts at constant surface speed would be doable.

I've seen this video before! It amazes me every time. It's amazing how
all those parts are just floating on air.

probably to much for hackPGH to buy, but it does give me some
inspiration for the lathe i am working on.
I am now looking up epoxy granite and air bearings.

I'm interested. How much would it be?
