Knife Edge Gyroscope.


A gyroscope mounted on a knife edge support will balance on the knife edge once it is rotating at sufficient speed. The gyroscope is brought up to speed by means of the gyroscope spinner, an A.C. motor with a rubber wheel attachment. Any slight imbalance in the gyroscope will cause it to precess. The gyroscope should be returned to its wooden support base when not in use to protect the knife edge .
