You are lucky to be inherited an old spotting scope from your Dad? Or you accidentally gleaned in a warehouse a moldy but still-runs-well spotting scope and want to renovate it to keep as a souvenir? The following article will help you to refurbish it properly.
Note: Keep in mind that in this article you will get to know a lot of small details, so it requires you to prepare adequate tools and to be clever in manipulating.
Observe and note the position of the components of the spotting scope (write down notes or take photos) to make sure you will not lose any components during the process of manipulation.
- Ensure the environmental sanitation because dusty environments will affect considerably the sanitary quality. Cover the ground with papers in case grease (if any) will stick to your arm, utensils and surfaces around.
- Prepare boxes for keeping screws and fasteners and other removed components to prevent losing them.
The materials you will need:
- A set of small screws.
- Tongs for picking up small screws and fasteners
- Rosin or soap to clean grease (if any), do not use acetone (the nail washing water) to clean because the surface will be flaked.
- Old brush
- Toilet paper or napkins
- Cotton swabs
Disassembling the spotting scope
Before disassembling the spotting scope, clean the outside body with washing water using a wet cloth so that external dust and dirt will not cling to the internal components.
- Remove the screws on the body of the spotting scope.
- Carefully remove the screw pads. It will be hard to find a substitute for some components if you damage them. So if the spotting scope is old, you should be as careful as possible. Use an adequate force, don’t pound when dismantling.
- When removing the pads, clean the screw holes with alcohol and swab. Remember to add some grease to the hole before reinserting the screws.
- Remove the viewing tube from the axis.
Checking and cleaning up
- If you detect signs of dust on the viewing tube, use a spray hose to blow away the dust layer.
Do not leave any grease, alcohol, dust, even lint of swab etc. stick into the lens.
In this stage, follow the similar steps in the previous stage.
- Disassemble screws that adjust focal length
- Remember exactly the position when reinserting the screws to avoid damage.
You can see the parts forming the lenses. Use a cotton swab and tissue to wipe these parts. As for the lens, gently wipe the dust; do not let any dirt leave on the lens.
Reassembling the components
After clean up all the parts, reassemble these parts in an opposite process of removing. Just remember to note the following points:
- Apply little oil on the screws.
- Tighten screws adequately, not too tight to avoid doing harms to the screws.
