Repair and Restoration of American Wooden Works Clocks

Description: American wooden clock movements were manufactured for only a few decades in the early 1800s but played a significant role in horological history and American industry. This three-day workshop will focus on disassembly, reassembly, service, and repair of American wooden works clocks.

Participants will accomplish the following:

·       Learn about the history of American wooden works clocks

·       Use identification tables to classify wooden movements

·       Understand the name and purpose of each clock part and how parts work in sequence

·       Assess a clock for functionality

·       Remove a movement from its case

·       Disassemble a movement into parts

·       Clean and condition wheels, plates, levers

·       Perform any necessary service and repairs

o   Tighten pillars

o   Bush plates

o   Polish pivots

o   Repair wheels with broken teeth

·       Reassemble a movement and synchronize the strike train

·       Put a movement into beat on a test stand and run it

·       Return the movement to its case and test run the complete clock

Participants will additionally learn about adjusting escapement pallets.

Equipment: Basic hand tools will be provided and will remain the property of the School. You may prefer to bring your own safety glasses and binocular magnifier (visor), watchmaker’s loupe, or similar magnification device. If you do not have safety glasses or magnification, they will be provided for you.

Clocks: A complete, running, synchronized clock will be provided for use during the workshop and will remain the property of the School. Participants are welcome to bring clocks with five-pillar Terry-type movements from home to be examined and assessed during the workshop, but please note that we cannot guarantee repairs or functionality within the scope of the weekend. If you have any questions, please contact education@nawcc.org.
