A reliable, convenient, & inexpensive way of solving the problem of worn, or mismatched chain & sprockets, on thirty hour clocks, which can cause the chain to jump & slip. The kit consists of 2 pinned sprockets, 2 centres manufactured from riveting brass, and a 12’ length of steel 33LPF clock chain.
The old centres and sprockets are machined off the original set leaving just the cheeks. The new set is assembled, mounting the old cheeks & new sprockets on the new centres. The use of the set also helps preserve the originality of the clock.
