Set to install new mainspring on an Ansonia clock movement, entirely time-based.
In the world of antique clock repair, few tasks require as much patience and care as properly cleaning and restoring a rusty mainspring. A recent project involving an Ansonia Extra Drop wall clock serves as a prime example of this meticulous process.
The Ansonia Extra Drop wall clock repair project is progressing, with the owner taking on the challenge of restoring a rusty mainspring that had threatened to halt the clock's operation. After disassembling the clock, the owner cleaned the parts, polished the pivots, and pegged the pivot holes.
**Steps to Clean and Restore a Rusty Mainspring**
1. **Disassemble the Clock**: Safely disassemble the clock to access the mainspring. This often involves removing the clock's dial and any other components that obstruct access to the mainspring.
2. **Power Down the Mainspring**: Before handling the mainspring, it's crucial to power it down to prevent injury. Use a mainspring winder or follow specific techniques to safely release the tension in the spring.
3. **Remove the Mainspring**: Once the tension is released, you can remove the mainspring from its barrel.
4. **Clean the Mainspring**: To clean the mainspring, use a combination of solvents and physical cleaning methods. Soak the mainspring in a mild solvent like naphtha or a gentle cleaning solution for a few hours to loosen rust. After soaking, use a soft-bristled brush to gently scrub away any remaining rust.
5. **Rust Removal**: For more severe rust, use a rust remover. However, be cautious with strong chemicals, as they can damage the metal. A safer approach is to apply a rust-inhibiting oil or a product like WD-40, which can help break down rust without damaging the spring.
6. **Dry and Lubricate**: After cleaning, ensure the mainspring is completely dry. Then, apply a light coat of clock oil designed for springs to prevent future rust and reduce friction.
7. **Reassemble the Clock**: Once the mainspring is clean and lubricated, you can reassemble the clock. Test the clock to ensure it operates smoothly.
**General Tips** - Always handle the mainspring with care, as it can still hold residual tension. - Use magnifying glasses or a loupe to inspect the mainspring for any remaining rust or damage. - Consider consulting a professional if you're unsure about any part of the process.
By following these steps, the owner was able to restore the rusty mainspring in the Ansonia Extra Drop wall clock, ensuring it continues to function well and maintain its value. The mainspring ran well for a couple of days after being reassembled and even completed the full 8-day cycle during the ultimate test.
The Ansonia Extra Drop wall clock is a time-only Rosewood veneered wall clock, manufactured by the Ansonia Brass and Copper Company in the early 1880s. The clock was in poor condition when bought, having come out of a barn. Despite its rough start, the clock had been running well for three years but in the last few weeks, it had stopped running for extended periods.
The owner's dedication to preserving the original parts of the clock led them to choose to clean the mainspring thoroughly instead of replacing it. This decision not only saved the mainspring from the recycle bin but also ensured the clock's history remained intact.
In addition to the Ansonia Extra Drop wall clock, the owner is also working on an Ansonia octagonal short drop wall clock, manufactured in 1912. With the success of restoring the mainspring in the first clock, the owner is optimistic about the repair project's future.
The owner, determined to restore the functioning and value of the Ansonia Extra Drop wall clock, took on the challenge of cleaning a rusty mainspring, a task known for its meticulous process. After disassembling the clock, powering down the mainspring, and removing it, the owner followed the steps to clean and restore the mainspring, including soaking it in a mild solvent, gently scrubbing away rust, drying it, and lubricating it with clock oil. This careful process allowed the mainspring to run well for a couple of days, even completing the full 8-day cycle during testing. Meanwhile, the owner also works on another vintage clock, an Ansonia octagonal short drop wall clock from 1912, hoping to apply their recent experiences in restoring gadgets like these antique clocks to this project as well.
