Hackaday

A detailed restoration of an antique mechanical clock that uses a rolling ball bearing as its time-keeping oscillator instead of a traditional pendulum or balance wheel. The restoration involved complete disassembly, cleaning, repairing bent pins with stronger replacements, applying protective lacquer, and extensive calibration work. The clock operates by having a ball bearing roll back and forth on an inclined plane, hitting a lever at each end to release energy and tilt the table in the opposite direction, achieving accuracy comparable to pendulum clocks.
