2. Lazy-Susan Design:
A simpler ball bearing of the type used for “lazy Susan” rotary tables was used. This
bearing has cast aluminum races, steel balls, and a plastic carrier for the bearing balls. The
inner and outer rings and the plastic ball carrier are cut to provide clearance for the
chronometer to be tilted forward for manual winding. Again, a servo motor and linkage
provides the rotary impulse motion. This design proved to be too loose to assure imparting
precision motion to the chronometer.
