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.

How to build and operate a simple mass spectrometer. Please ask questions in the comments, as always.
Scientific American article: https://www.scientificamerican.com/article/the-amateur-scientist-1970-07/ $7.99 is a good value for the entire back issue in plain PDF format, and an example of a publisher being reasonable. I'm happy to support this.
