What You'll Learn
Take pictures and notes during disassembly to ease reassembly
Taking pictures and making notes during the disassembly process will make it much easier to put your vintage electric fan back together. It is a good idea to take pictures of each step and to keep track of the order in which you remove parts. Label the parts with taped-on tags, numbered in the order they are removed. This will make it easier to identify them when it's time to reassemble the fan.
You can also make drawings of the disassembly process, which can be helpful for visual learners. Note down any unique or distinct features of each part, such as the presence of oil or grease, rust, dirt, dust, or debris. These notes will be useful when it comes time to clean and restore the fan to its original condition.
Additionally, keep track of the location of screws and other small parts. The screws that hold the fan blades in place, for example, may be located under the blades themselves. By taking note of their location, you can ensure that you don't lose any essential components during the disassembly process.
Taking pictures and making detailed notes will also help you identify any potential issues or damage to the fan. For example, you may want to inspect the rotor and stator for any signs of damage and make notes on their condition. This information can be useful for future repairs or maintenance.
Finally, don't forget to document the disassembly process as you go. It's easy to forget the exact order in which parts were removed or the specific steps taken to detach certain components. By taking pictures, making notes, and labelling parts as you work, you'll have a comprehensive record that will make reassembling your vintage electric fan a much smoother process.

Remove the blade cage and brackets
To remove the blade cage and brackets, you will need to expose the screws that attach the cage to the metal cover around the motor. These screws are located under the fan blades. Once you have located the screws, use a screwdriver to remove them. If the screws are difficult to turn, you may need to apply a penetrant like WD-40 to help loosen them.
After removing the screws, gently lift and manoeuvre the cage around the blades to detach it from the motor. Be careful not to damage the blades or the cage during this process. Set the cage aside in a safe place, ensuring that it doesn't roll or cause injury.
Next, focus on removing the brackets that secure the blades in place. These brackets may be attached with screws or other types of fasteners. Identify the type of fasteners used and select the appropriate tools for removal. It is important to work carefully and methodically, ensuring that you do not strip any screws or damage the brackets during this process.
Once all the fasteners are removed, gently lift and detach the brackets from the blades. Again, be cautious to avoid any damage to the blades or brackets. Set the brackets aside, keeping them separate from the cage to avoid mixing parts.
With the blade cage and brackets removed, you can now access other internal components of the fan for inspection, cleaning, or further disassembly. Remember to take pictures or make drawings of the disassembly process, as it will aid in reassembling the fan correctly.

Inspect the fan's overall condition
Inspecting the fan's overall condition is an important step in the disassembly process. Firstly, look for any missing parts or broken pieces that will need to be replaced or repaired. Pay close attention to the external electrical wiring, as age and previous use can cause it to become hazardous. Remove the blade cage and brackets and try to spin the blade to check if it is seized up. If the fan is not functioning properly, a basic diagnosis can be performed to ensure proper functionality and performance. This includes the disassembly of major components, electrical analysis, rewiring of the head and base units, and lubrication of primary parts.
For a more advanced inspection, you can take the fan apart further and inspect the internal components. Remove the fan blade and set it aside, then take off the fan motor cover to expose the internal rotor and stator. Check the rotor and stator for any signs of damage. The rotor and stator play a crucial role in the fan's functionality, so it is important to ensure they are in good condition.
If the fan has not been used in a while or is particularly old, it is likely to be dirty or greasy. In this case, you will need to clean all the fan parts before proceeding. Use a chemical stripper or sandblasting to strip down any previously painted surfaces to the bare metal. This will ensure that the fan is free of any oil, grease, rust, dirt, dust, or debris before you start the disassembly process.
Once you have inspected the fan's overall condition and performed any necessary cleaning or repairs, you can continue with the disassembly process. It is recommended to take pictures or make drawings of the fan as you disassemble it, as this will make reassembly much easier. Additionally, you can use taped-on tags labelled numerically in the order the pieces are removed to facilitate the reassembly process.

Remove the fan motor cover to expose the rotor and stator
To remove the fan motor cover and expose the rotor and stator, you will first need to remove the fan blade. Set the blade aside in a safe place. Next, locate the screws that hold the motor cover in place. These are usually found under the fan blades. Once you have located the screws, use the appropriate tool to unscrew and remove them.
With the screws removed, you can now take off the motor cover. Gently lift and manoeuvre the cover around the blades. Take care not to damage the blades or any other components during this process. As you remove the cover, pay attention to the internal mechanisms of the fan. The rotor and stator should now be visible.
Before proceeding further, take a moment to inspect the exposed rotor and stator for any signs of damage. Look for any debris, wear, or damage to the components. If you notice any issues, make a note of them for further inspection or repair. It is important to ensure that these parts are in good condition before reassembling or operating the fan.
Now that you have successfully exposed the rotor and stator, you can continue with the disassembly process or proceed with any necessary repairs or maintenance tasks. Remember to keep your workspace organised and to handle all components with care to ensure a smooth process and avoid any damage to your vintage electric fan.

Clean and polish the fan blades and fittings
To clean and polish the fan blades and fittings of a vintage electric fan, you must first disassemble the fan. Remove the blade cage and brackets and set the blade aside. Then, remove the fan motor cover to expose the internal rotor and stator. Next, carefully inspect the rotor and stator for any damage.
Once disassembled, you can begin the cleaning process. Start by removing any oil, grease, rust, dirt, dust, and debris from all fan parts. Pay close attention to the fan blades, as these are more prone to rust and dirt buildup. Use a soft cloth or brush to gently wipe down the blades and remove any visible debris. If the fan blades have rust spots, try rubbing vinegar on the affected areas, letting it soak for about 10 minutes, and then wiping it off. Alternatively, you can use a chemical stripper or sandblasting to strip down the painted surfaces to bare metal.
If the fan blades and fittings are made of brass, you can polish them to restore their shine. First, determine if there is any original clear brass lacquer on the brass parts. If there is, use a paint remover to get it off. Then, for brass or steel parts only, pour Lysol Toilet Bowl Cleaner into a glass or plastic bowl and moisten a pad of 0000 steel wool with the solution. Wear rubber gloves and ensure good ventilation during this process. Carefully buff the brass parts until they are shiny. Start with brown rouge, then switch to white rouge on a new buffing pad to remove any buffing marks. Remember to use heavy gloves during buffing to protect your hands from the heat generated. Once the brass has cooled, polish it by hand with Brasso to achieve a fine finish.
After cleaning and polishing, you can apply a base coat of metal primer before applying the finish coat of paint. Ensure all repairs are made to the electrical and mechanical components of the fan, soldering electrical connections and protecting them with heat shrink tubing. Finally, reassemble the fan, and it will be ready to use or display.
