Learning Techniques for Initiating a Social Movement: Installment 32 of Talk Tick Tuesday Discussion
In the world of horology, maintaining and repairing clocks requires precision, patience, and the right tools. One such tool that horologists prize is the Bergeon Bushing Machine, a device that helps restore worn pivot holes in clock movements.
When a clock's pivot holes become worn, the movement can malfunction. To remedy this, the worn holes are drilled or reamed to an exact size, and a new bushing is inserted. Here's a detailed procedure for hand bushing a clock movement using a Bergeon-type bushing machine:
1. Preparation: - Remove the clock movement from its case, and carefully disassemble to gain access to the plates that need bushing. - Clean the plates thoroughly to remove old oil, dirt, and debris. - Identify and measure the worn pivot holes that require bushings. Use a pivot hole gauge or micrometer for accurate sizing.
2. Drilling or Reaming the Hole: - Using the bushing machine’s fine drill or reamer tool, carefully widen the worn hole to a precise size to accept the new bushing. - The Bergeon machine has interchangeable broaches and drills designed to provide exact sizing. - Take care to ensure the hole is straight and centered, avoiding any damage to the plate.
3. Inserting the Bushing: - Cut or select the appropriate size brass bushing tube. The bushing must have an outside diameter matching the newly drilled hole. - Some bushings come pre-sized; otherwise, carefully cut a short length to fit. - Place the bushing over the drill or insertion tool on the Bergeon machine. This insertion tool is designed to tap the bushing into the hole gently but firmly. - Align the bushing with the hole, then push or tap the bushing into place until it sits flush or slightly proud on the plate.
4. Trimming and Finishing: - After insertion, use the machine’s countersink or hand tools to trim any excess bushing length flush with the plate. - File or burnish the bushing edges to ensure a smooth fit and prevent damage to pivots. - Ream the inside of the bushing to the correct diameter for the pivot shafts using the machine’s broach tools, ensuring a precise fit.
5. Reassembly and Testing: - Once all required bushings are installed and finished, reassemble the clock movement. - Carefully oil pivots, reinsert wheels, and test the movement for smooth running and correct endshake. - Adjust further if needed.
The Bergeon Bushing Machine is highly valued because it holds the movement securely, provides precise drilling, reaming, and bushing insertion tools, and allows the watchmaker or clockmaker to work with great accuracy.
