Abstract

[Servicing of domestic synchronous clocks is not financially viable for professional clockmakers so servicing usually has to be carried out on a do it yourself (DIY) basis. This requires both clockmaking and electrical tools and skills. There are so many variables that it is only possible to give general guidance. New original spare parts are in general not available. Synchronous movements removed from clocks that have been scrapped or converted to quartz are sometimes available as a source of used original spare parts. Otherwise, the only source is to sacrifice a synchronous clock. Some items are available from horological suppliers. These include round and square clock glasses, hand set and starter knobs, and taper pins. BA threads are used in most British domestic synchronous clocks so replacement nuts and bolts can be obtained from horological or engineering suppliers. A systematic approach to fault finding is needed. Faults may be due to fair wear and tear or be the result of tampering. One clock examined had six distinct faults, all due to tampering. Provided that the motor coil is intact, cleaning and lubrication, and perhaps replacement of the mains lead, is usually all that is needed to get a synchronous clock that has stopped working back into running order. If there no apparent electrical faults are apparent, and a synchronous clock does not work, then it will have to be dismantled to find and rectify the fault or faults. Normal clock making techniques may be used.]
