Typically when customers bring me their clock which has stopped working, an inspection reveals that a complete overhaul is required. An overhaul consists of the following elements:

  • Strip all parts.
  • Clean thoroughly in three stage process, finishing with fan heat drying to prevent moisture in crevices from leading to corrosion.
  • Inspect all parts for wear or damage.
  • Repair damaged parts.
  • Dress and polish worn pivots and pinions. (Pinions are the smaller steel gears that mesh with the larger brass gear wheels).
  • Remove rust from steel parts.
  • Grind and polish rutting from worn pallets.
  • Reassemble and lube with specialised clock oil.
The clock is now in perfect mechanical condition and will be test run and adjusted through several winding cycles to ensure reliable and accurate performance. This process sounds simple enough, but as there are many parts in a striking or chiming clock and some of the repair processes are very labour intensive, it can take a day or more to carry out a thorough overhaul.

Typical mechanism before....during.....and after cleaning and repairs

These clocks have quite complicated mechanisms consisting of gear trains, usually powered by mainsprings or weights. After many years of working twenty four hours a day seven days a week, these clocks accumulate a lot of mechanical wear which can't be fixed with a "quick clean and oil."

Battery / Quartz Clocks: If you have a problem with a battery powered quartz clock, I can usually assist with the supply and fit-up of replacement movements and hands for these clocks.
