Copal Shutter Repair: How to Fix Loose Blades

Copal shutters are a popular choice for photographers due to their durability and reliability. However, over time, these shutters can become worn out and require repair. One common problem is loose diaphragm and shutter blades, which can lead to uneven exposures and blurry images. This tutorial video will guide you through the process of repairing a Copal #0 shutter with loose blades.

Tools and Materials

• Copal #0 shutter
• Small screwdriver set

Steps

1. Disassemble the Shutter: Begin by carefully removing the shutter from your camera. Using a small screwdriver, remove the screws that hold the shutter assembly together. Be careful not to damage any parts.
2. Inspect the Blades: Once the shutter is disassembled, inspect the diaphragm and shutter blades for any signs of wear or damage. If the blades are loose, they may need to be replaced.
3. Remove the Old Blades: Using tweezers, gently remove the old blades from the shutter assembly. If the blades are stuck, you may need to use a small screwdriver to pry them off.
4. Install the New Blades: Once the old blades are removed, install the new blades in their place. Be sure to align the blades correctly so that they close properly.
5. Reassemble the Shutter: Once the new blades are installed, reassemble the shutter assembly. Use a small screwdriver to tighten the screws that hold the assembly together.
6. Test the Shutter: After reassembling the shutter, test it to make sure that it is functioning properly. You can do this by setting the shutter speed to different settings and observing how the blades open and close.

Troubleshooting

• If the shutter blades are not closing properly, you may need to realign the blades. This can be done by using tweezers to gently adjust the position of the blades.

Safety Precautions
