  1. Bearings for home-built gyroscope?

    18 April 2012 - 06:07 PM

    One of the projects on my back burner array is making a gyroscope out of an old 6" ball bearing race. One of the things I need to figure out is how to mount the spindle in the frame.

    Given the mass of the thing, the mounting needs to be robust in order to resist the effects of precession. My first thought was to use a needle bearing:

    but that would require a seriously hardened spindle tip and equally wear-resistant fitting. And precession thrusts would probably do neither much good.

    Next I considered a simple ball-bearing:

    and that's the best I've been able to come up with. Shoulder bearings such as used in 'jewel' watches would require the fitting to be adamantine and refractory. and there'd need to be at least a tiny bit of play. One's hard to come by, and the other's not something I want in a fairly massive device spinning at thousands of RPM.

    Any thoughts or suggestions on a solution suitable to construction in a home shop?

    Thanks!
