Black metal

Only a little bit of it, but new in the Guan Post-Academic Year Collection is this finely crafted piece of machinery.

It’s some sort of air-bearing spindle assembly, probably meant to spin obscenely fast. Two pneumatic bearings support a very smoothly polished stainless steel shaft, on the ends of which are perched what suspiciously appear to be former brushless motor parts. There is a 8-magnet assembly at the far end wrapped in Kevlar, next to a hub-like piece. On the close end is four very large rare-earth magnet assemblies, each with 8 magnets, and curiously, each is offset by a few degrees. I suspect this was a stepper of some sort. These are very powerful magnets.

I happen to have a small compressor that I might fire this thing up with, just to see it spin, I suppose.
