Fixing a Jammed Self-Timer on a Compur #00 Shutter

The Compur #00 and #0 shutters are renowned for their robust construction and smooth operation, but they can sometimes fall victim to a common issue: a jammed self-timer. This can leave you frustrated and unable to capture those perfectly timed shots. Fear not, because this guide will walk you through the process of disassembling and lubricating the self-timer mechanism to restore your shutter to its former glory.

Understanding the Problem

The self-timer mechanism in a Compur #00 shutter relies on a series of gears and springs to create a timed delay. Over time, these components can become gummed up with old lubricant or debris, leading to the self-timer sticking. This can manifest as a sluggish or non-functional self-timer.

Tools and Materials

Before you begin, gather the following tools and materials:

• A small screwdriver set
• A pair of tweezers
• A magnifying glass (optional)
• Camera cleaning solution
• A small brush or cotton swab
• Camera oil or light machine oil (a small amount)

Disassembly

1. **Remove the Lens:** Carefully detach the lens from the camera body, making sure to note the orientation of any screws or other components.

2. **Access the Shutter:** Locate the shutter assembly. In most Compur #00 cameras, this will be visible once the lens is removed. Look for the round shutter mechanism with a series of levers and gears.

3. **Remove the Self-Timer Mechanism:** The self-timer mechanism is usually located on the side of the shutter assembly. Identify the small, round self-timer knob and the surrounding components. Using a small screwdriver, carefully remove the screws securing the self-timer mechanism.

Cleaning and Lubrication

1. **Cleaning:** Once the self-timer mechanism is removed, use a small brush or cotton swab dipped in camera cleaning solution to carefully remove any dirt or debris. Pay particular attention to the gears and springs.

2. **Lubrication:** Apply a small amount of camera oil or light machine oil to the gears and springs of the self-timer mechanism. Avoid over-lubrication, as this can cause the mechanism to become sluggish.

Reassembly

1. **Reverse the Disassembly Process:** Carefully reassemble the self-timer mechanism, ensuring that all components are properly aligned. Tighten the screws securing the mechanism.

2. **Reattach the Lens:** Reattach the lens to the camera body, making sure that all screws and components are properly secured.

Testing

Once the camera is reassembled, test the self-timer function. It should now operate smoothly and without any sticking or jamming.

Tips

• Work in a clean and well-lit environment to prevent dust and debris from contaminating the camera.
• Use a magnifying glass to ensure that all components are properly aligned during reassembly.
• If you are unsure about any step, consult a qualified camera repair technician.

By following these steps, you can effectively fix a jammed self-timer on your Compur #00 shutter and enjoy trouble-free photography once again. Remember to handle your camera with care and use the appropriate tools for the task.
