The rebushing process consists of restoring the worn pivot holes on the movement plate and polishing the pivots that turns in the hole. The two plates of the clock movement support the wheels which turn in holes drilled into the plates.
To repair or “rebush” the holes in the plates we must disassemble the movement and place it in a variety of chemicals, which degreases and removes all the dirt. The wheels are then chucked up into a lathe and the end of the wheels, called the pivots, are inspected and then go through a series of polishing techniques to repair the surface of the pivots which have been scarred after years of turning in the holes. The movement is then reassembled and each hole is inspected to determine if installing a bushing for that hole is necessary. Once again the movement is taken apart. The worn holes are bored out and hardened brass bushings are driven into the plates to create a new and round surface for the pivots to fit into. All the holes are then fitted properly and oil sinks are cut into the bushings to insure for proper lubrication. Once again the movement goes through a series of cleaning and rinsing solutions and the movement is then reassembled and all functions are checked to make certain the clock is functioning as the manufacturer intended.
