Piezo-electric disc mounting methods and apparatus
 A piezo-electric disc (e.g., a force transducer or a radio reference crystal) is mounted on its edge between two opposing anvils of material which is selected to plastically deform only under a relatively high proof load applied to the disc through the anvils while an extreme pressure lubricant is present between the edge of the disc and the anvils to provide seats of limited area for the edge of the disc.
