Kitchen Clock Repair Workshop


Next Workshop Dates: August 17 - 20

9AM to 5PM.

Class is full

Introduction: This four-day workshop covers clock movements typically found in antique American kitchen and mantle clocks - namely, the 8-day time and strike movement with open main springs.  It 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 - disassembly, cleaning, assembly, lubrication, and adjustment for this type of movement.  In addition, students will be introduced to clock nomenclature, the proper way to let down power for 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:

Clock movement (IMPORTANT!!!): Students must find and bring one or more American open mainspring clock movement(s) with them to work on in the class - movements will not be provided. Movements must include all parts including pendulum, springs, suspension springs, etc. These are routinely available through eBay or inside inexpensive kitchen/mantle clocks for sale at local antique stores.

Note: Please bring a movement with potential for being repaired - i.e., no basket cases. If you have any questions please call or email the instructor (Mark Vozar @ 817-399-9894

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 kits available for use during class containing the clock specific tools and any other tools or materials you will need to complete the class. So if you want to try your hand at Clock Repair before purchasing a lot of equipment you may check out a tool kit. Please call/email the instructor if you have any questions.
