Make vacuum pre-loaded spherical air bearings without special tools https://tube.loping.net/videos/watch/cc0b1ec0-c225-42b9-b5b6-fbecc1f77e23 A new technique to make graphite air bearings without precision tooling. I show how to make spherical, cylindrical, and flat bearings that are also vacuum pre-loaded, meaning the bearing is captive.
