Introduction: This four-day workshop covers the Striking clock movement, typically found in antique American kitchen and mantle clocks; namely, the 8-day Count Wheel, time and strike movement with open main springs. This course is intended for collectors and beginning clock repair enthusiasts who want to do simple repairs to their own clocks.

What you will learn: Basic repair skills, to include disassembly, cleaning, re-assembly, lubrication, and adjustment. In addition, students will be introduced to clock nomenclature, the proper way to let down power on open main springs, re-bushing, pivot polishing, wheel and arbor repair/adjustment, as well as the theory and practice of time train calculations.

What you will need: Students must find and bring one or more American Open Mainspring, Count Wheel movement(s) to the class. Your Count Wheel movement(s) must have all parts; including pendulum, main springs, suspension springs, etc. These are routinely available through eBay or inside inexpensive kitchen/mantle clocks for sale at local antique stores.

IIMPORTANT: Movements will not be provided. Please bring a movement with potential for repair. No basket cases, please.


Tools: It is recommended that the student bring the following tools to class. Try to bring as many of the non-clock repair specific tools as possible. The Chapter has a few kits available for use during class, which contain the clock specific tools and any other tools and materials you will need to complete the class.

You should decide on the quality of tools you want. Although higher quality tools are more expensive, they will last longer and perform much better than economy tools. When purchasing higher quality hand tools, look for brand names; such as, Bergeon, Dumont, Swanstrom, Lindstrom, Corradi, Grobet, and Peer-Vigor. Many economy tools are made in China, Pakistan or India. These tools are usually made with soft steel and may not perform well.
