Understanding the significance of the phrase: "bushing a clock"
In the fascinating world of mechanical clocks, a crucial aspect of their maintenance is the process known as bushing. This repair method is essential when dealing with worn pivot holes, a common issue in vintage or antique clock repairs.
Bushing involves replacing the worn brass around the pivot, thereby restoring the hole's round shape. The typical steps to perform bushing are as follows:
- Drill out or clean the worn pivot hole: This step removes any damage, oversize areas, or irregularities in the hole.
- Stamp or press a precisely sized brass or similar metal bushing into the cleaned hole. The bushing is an accurately sized tube that fits the original pivot dimension.
- Cut or ream the bore of the bushing: This step ensures that the bushing's diameter matches the clock pivot exactly, promoting smooth rotation without play or binding.
- Securely set the bushing in place: This is usually done by staking or peening, to prevent movement.
By re-establishing a stable and properly sized bearing surface in the pivot hole, the pivot can rotate freely and accurately within the clock's movement.
The Role of Pivots
Pivots are ends of axles in mechanical clocks that spin in small holes drilled in the clock plates. They are crucial for the smooth operation of the clock's gears. However, over time, due to wear and tear, these pivots may become worn, causing the gear to move away from the pinion and eventually stop when the gears no longer mesh properly.
The Mission-Style Clock
The article under discussion features a mission-style clock made by the Sessions Clock Co. of America in the 1920s. This clock, found in a thrift shop in Pembroke, Ontario, was in need of repair due to erratic running or complete stoppage, a symptom often indicative of bushings.
Regular Servicing
Regular servicing of mechanical clocks is essential to reduce wear and tear, preserving the clock's functionality. Ideally, most clocks should undergo servicing every three to five years. Over-oiling without proper cleaning can lead to worn pivots, as found in this mission-style clock.
The Importance of Proper Cleaning
Proper cleaning involves disassembly, cleaning the parts, addressing wear issues, reassembly, and testing. This process ensures that the clock runs smoothly and accurately.
In conclusion, bushing is a vital technique in the repair and maintenance of mechanical clocks. By understanding and implementing this process, clock enthusiasts can ensure their vintage and antique clocks continue to tick away, keeping time accurately for generations to come.
- To keep a mission-style clock made by the Sessions Clock Co. of America, found in a thrift shop, functioning properly, it is crucial to address the issue of worn pivots, often indicative of bushings, through the process of clock repair.
- For the home-and-garden enthusiast seeking to add a touch of vintage charm to their lifestyle, the restoration of a vintage clock using the bushing repair method could complement their collection of gadgets and technology.
- Regular servicing of mechanical clocks every three to five years, including proper cleaning that addresses wear issues, can help minimize the need for complex repairs like bushing and prolong the lifespan of the clock, thus preserving its value as a unique piece of home-and-garden decor.
