Exploring the Fascinating World of Clocks: Random Clock Talk 19

Clocks have long been an integral part of human lives, and the history of clock-making goes back thousands of years. From grandfather clocks to watches, clocks come in different shapes and sizes, and they all share a common trait – they tell time. But beyond this, clocks are intricate and complex machines that require great precision for their accurate functioning. In this article, we’ll dive into the fascinating world of clocks and explore some of the different aspects of clock-making.

The Video Discusses Pivot Work in American Antique Clock Movements

One of the most critical components of a clock movement is the pivot. The pivot acts as a fulcrum, allowing the various clock wheels to rotate. In the video, we get a detailed look at the process of pivot work, specifically in American antique clock movements. The technique involves using different tools such as a pivot file, burnisher, and stone to polish the pivot.

The Precision Pivot Polishing Bed is Constructed of a 1/8 Inch Diameter Brass

To ensure that the pivot polishing is accurate, clockmakers use a precision pivot polishing bed. This tool is constructed of a 1/8 inch diameter brass, making it sturdy and reliable. The diameter of the pivot hole is about 40% cut into the brass, and this allows for precision work to be done on the pivot.

The Polishing Technique Includes Pivot File, Burnisher, and Stone

Polishing the pivot requires different tools, each serving a unique purpose. The pivot file is the first tool used in the process. It is used to remove any burrs or nicks from the pivot’s surface, giving it a smooth finish. The burnisher is used to harden the pivot’s surface, making it less susceptible to wear and tear. Finally, a stone such as a Jasper stone is used to polish the pivot’s surface, giving it a mirror-like finish.

The Video Shows Inspecting the Classic American Clock Movement

Inspecting the clock movement is an integral part of ensuring that it runs accurately. In the video, we see how clockmakers inspect classic American clock movements. They check for any damage or wear in the various components, and they make adjustments to ensure smooth running.

The Equipment Includes a Lathe and a Collet for the Driving Pin

To drive the pivot, clockmakers use a lathe and a collet for the driving pin. The lathe is used to turn the pivot with precision, while the collet ensures that the driving pin is securely fastened.

The Video Shows the Use of a Carrier or Driving Dog for Polishing the Opposite End of the Pivot

In clockmaking, polishing the pivot is not the only step. The opposite end of the pivot needs to be polished as well. In the video, we see how a carrier or driving dog is used to facilitate this process. This helps to ensure that the pivot is smooth and well-polished on both ends.

The Video Shows the Use of a Roller Rest for Supporting the Polishing Tools

During the pivot polishing process, it’s important to support the polishing tools to ensure precision. This is where a roller rest comes in. The rest is used to support the tools and prevent any slippage, ensuring accuracy.

Pivot Working Tools Include Ball Faced Punches, Flat Faced Punches, a Driver, and a Female Center

To perform pivot work, clockmakers use various tools, including ball-faced punches, flat-faced punches, a driver, and a female center. These tools are crucial in ensuring that the pivot is polished to perfection.

The Precision Pivot Polishing Bed Ensures High Accuracy

The precision pivot polishing bed plays a crucial role in ensuring that the pivot work is accurate. Its construction ensures that the pivot works are uniform and precise, leading to better accuracy in clock movements.

The Video Shows the Use of a Crank Pin Carrier for Driving the Wheel

Driving the wheel is an essential part of ensuring that the clock keeps time accurately. In the video, we see how a crank pin carrier is used to facilitate this process, making it easier to drive the wheel.

The Video Shows the Use of a Driving Pin for Removing the Wheel

Removing the wheel is another crucial step in clock movement repair. In the video, we see how a driving pin is used to remove the wheel, making it easier to perform necessary repairs.

The Equipment Includes a Set of Pivot Beds with Different Sizes

Clockmakers need to use different sizes of pivot beds, depending on the pivot’s size. The equipment includes a set of pivot beds with different sizes, ensuring that any pivot can be worked on with precision.

The Video Demonstrates Roughing the Pivot with a Pivot File and Finishing It with a Burnisher or Jasper Stone

Roughing the pivot with a pivot file is the first step in the pivot polishing process. In the video, we see how the pivot file is used to remove burrs and nicks from the pivot’s surface. Once the pivot has been roughed, a burnisher or Jasper stone is used to polish the pivot’s surface, giving it a mirror-like finish.

The Lathe Can Run at a Speed of Up to 2,000 RPM

The lathe is an integral part of the clockmaking process, and it can run at a speed of up to 2,000 RPM. This ensures that the pivot is turned with precision and accuracy, leading to better clock movements.

Conclusion

Clockmaking is a fascinating field that requires precision and accuracy. The pivot is one of the most critical components, and the pivot polishing process is intricate and detailed. By using different tools and equipment, clockmakers can ensure that clock movements run smoothly and accurately.
