What You'll Learn
The best glue to use
When it comes to gluing a bakelite pan handle, choosing the right adhesive is crucial for a strong and durable repair. The best type of glue to use for this purpose is an epoxy adhesive. Epoxy is a versatile and highly effective adhesive known for its superior strength and durability. It is capable of creating a strong bond between the bakelite handle and the pan, ensuring a long-lasting repair.
There are two main components to epoxy adhesives: the resin and the hardener. When mixed together, they create a chemical reaction that results in a strong and rigid bond. This makes epoxy an ideal choice for bonding dissimilar materials, such as metal and bakelite.
When selecting an epoxy adhesive, look for a product that is specifically designed for bonding metal and hard plastics. These types of epoxy adhesives are usually formulated with a stronger and more resilient bond in mind. It is also important to ensure that the epoxy you choose is heat-resistant, as the handle will be exposed to heat from the pan.
Before applying the epoxy, clean and prepare the surfaces of both the bakelite handle and the pan to ensure that the adhesive will bond effectively. Use a solvent or alcohol to wipe down the surfaces, removing any grease, oil, or dirt. Once the surfaces are prepared, mix the epoxy resin and hardener according to the manufacturer's instructions.
Apply a generous amount of epoxy to both surfaces, making sure to spread it evenly. Carefully align and position the bakelite handle to the pan, applying firm pressure for the recommended amount of time specified by the epoxy manufacturer. Allow the epoxy to cure completely before using the pan, typically for at least 24 hours.

Preparing the surface
Start by cleaning the surface of the handle to remove any dirt, grease, or grime. Use warm soapy water and a soft cloth to gently wipe down the handle. Rinse it with warm water and dry it thoroughly with a clean cloth. This step is crucial as it ensures that the glue will properly adhere to the surface.
Next, you need to roughen the surface of the handle to create a better grip for the glue. You can use fine-grit sandpaper to gently buff away any deep scratches and create a slightly textured surface. Be careful not to over-sand the surface, as you still want a smooth finish. If there are any metal parts, make sure to rough them up as much as possible to give the epoxy something to grip onto.
After sanding, wipe away any dust or debris with a clean, dry cloth. You can also use a soft brush to remove any remaining particles. It is important to ensure that the surface is completely clean and free of any residue before proceeding to the next step.
If your pan handle has any metal parts, such as a metal blade or rivets, you may need to drill holes alongside them to create a stronger bond. This will allow the epoxy to flow into the holes and create a mechanical lock in addition to the chemical bond of the glue. Make sure to drill the holes carefully and at the correct depth, following any instructions specific to the type of epoxy you are using.
Finally, inspect the surface to ensure that it is properly prepared. The surface should be clean, roughened, and free of any dust or debris. Once you are satisfied with the surface preparation, you can proceed to the next step of applying the glue. Remember to work in a well-ventilated area and follow the instructions provided by the manufacturer of the glue you have selected.
By following these steps for preparing the surface, you will increase the chances of a successful bond when gluing your bakelite pan handle.

Applying the glue
When applying the glue to the Bakelite handle, it is important to use a small brush or toothpick to apply a thin layer evenly to the surface. Avoid applying too much pressure or rubbing the glue into the Bakelite, as this could lead to discoloration. The type of glue you use is important, and epoxy is recommended for its strength and durability. You can also use polyurethane glue, which takes longer to cure, or super glue and urethane glue, which dry in a few minutes.
Before applying the glue, ensure the surface is clean and roughened to create a stronger bond. You can use a chainsaw file or a Dremel tool to roughen the surface. If the handle has broken into multiple pieces, drill small holes in the Bakelite pieces and use wire to pin them together for added strength. This will help to reinforce the handle and create a stronger bond with the glue.
Apply a light coat of epoxy to the broken surface, especially around any rivets or metal attachments. Squeeze the pieces gently together, being careful not to clamp them too tightly. You can also use screws to hold the pieces together while the glue dries. If you do use screws, be sure to wipe away any excess glue before it dries.
It is important to allow the glue to fully dry before handling the handle. Epoxy and polyurethane glues can take up to 24-48 hours to cure completely, while super glue and urethane glue dry much faster, in just a few minutes. Place the handle in a well-ventilated area to facilitate the drying process, and ensure it is resting on a flat surface to allow the glue to dry evenly.
After the glue has dried, you can remove any clamps or screws used to hold the pieces together. Be careful not to shake or damage the handle. Finally, clean up any residual glue on the surface of the Bakelite to ensure a seamless finish.
