Air handling, fitering etc. for air spindle bearings?
sparky961:
Maybe you can fins a bar (pub), have a few drinksdrinks, and play around with an air hockey table for a while. Or is that just a Canadian thing?
PekkaNF:
Those air hockey tables and most of that stuff has it all wrong.....
Normal consumer gets close to air spindles on hard drives and processor cooling fans. I did some more reading and there seems to be some issues that are hard to solve easily on DIY resources. Orifice type needs some real knowledge and experimentation, not to mention making orifices....but I have an idea on that one. Porous type would be a magnitude easier IF you had the porous (graphite) material.
Having low friction is one thing. Getting it stable and rigid/stiff is another altogether. Let's see, maybe I'll never get out of armchair with this topic.

I would like to test linear motion over granite surface plate. Just something for quick testing. Any ideas?

The inventor of hoovercraft vehicles supposedly used a shoebox and a vacuumcleaner in reverse when he tried out his ideas. Don't know if it helps you with your idea?
PekkaNF:
There is quite a bit of industrial applications where material is moved by applying a film of air underneath. This is to reduce friction. No concideration on how far and how stable the surface is moved.
Intended use of air bearings is a little different matter. Challenge is in metering and distributing correct air flow/pressure profile between two layers and keep them at nearly constant distance. Oldest for is to make two surfaces very flat and smooth and meter air flow with an orifice. Lifting tendency is moderated with an opposing similar arrangement.
There is a short application guide:

Found some calculators.
