How to Build a Forge from a Brake Drum

Creating a forge from a brake drum is a popular project among blacksmiths and metalworkers, especially for those who want an affordable and efficient way to heat metal for shaping and forging. A brake drum forge is compact, portable, and can reach high temperatures, making it an excellent choice for beginners and experienced metalworkers alike. In this article, we will guide you through the process of building a simple and effective forge from a brake drum.

Materials Needed

Before you begin, you'll need to gather the following materials

1. Brake Drum Find a used brake drum from a vehicle. You can often get these cheaply from auto repair shops or scrap yards. 2. Hardfire Brick This will help insulate the inside of your forge. 3. Propane Tank and Regulator For a propane-powered forge, you’ll need a standard propane tank and a regulator to control the flow. 4. Burner You can either purchase a pre-made burner or make one using a pipe and a nozzle. 5. Refractory Cement To coat the inside of the forge for better heat retention. 6. Tools You will need basic tools such as wrenches, a drill, and safety equipment.

Step-by-Step Instructions

1. Prepare the Brake Drum Begin by cleaning the brake drum thoroughly. Remove any rust, dirt, or grease to ensure a clean working surface. If necessary, you can use a wire brush or grinder to help with this.

2. Insulate the Interior Cut hardfire bricks to fit snugly inside the brake drum. These bricks will help to hold heat and provide insulation. Arrange them in a circular pattern within the drum, leaving space for your burner. Consider using refractory cement to secure the bricks in place and fill any gaps.

3. Install the Burner Choose a suitable spot on the brake drum for the burner. Drill a hole that matches the diameter of your burner pipe. The burner should be positioned at an angle to create a swirling effect that helps distribute heat evenly throughout the forge. Secure the burner with bolts and use high-temperature sealant to prevent gas leaks.

4. Create the Forge Opening To allow access to the forge, you'll need to make a small opening on the side of the brake drum. This is where you will insert the metal pieces that you want to heat. Ensure this opening is large enough to accommodate your projects but small enough to maintain temperature.

5. Connect the Propane Tank Attach your propane tank to the burner using a hose and regulator. Follow all safety protocols during this process to prevent any gas leaks. Ensure that all connections are tight and secure.

6. Seal the Forge Use refractory cement to coat the interior of the brake drum, enhancing the insulation. Make sure to leave the burner opening clear, and give the cement ample time to cure based on the manufacturer's instructions.

7. Test Your Forge Before you start forging, conduct a test run. Open the propane tank valve slightly and ignite the burner using a long lighter. Observe the flame and ensure that the burner is functioning correctly. Adjust the burner as necessary to achieve the desired flame size and heat output.

8. Safety First Always prioritize safety. Use appropriate personal protective equipment (PPE), including gloves, goggles, and protective clothing. Work in a well-ventilated area and keep a fire extinguisher nearby.

Conclusion

Building a forge from a brake drum is a rewarding project that can enhance your metalworking capabilities. With careful planning and execution, you can create an efficient and effective forge that will serve you well for years to come. This DIY project not only saves money but also provides a great opportunity to learn about metalworking processes. Enjoy the journey of metal shaping and forging!
