How to Build a Forge from a Brake Drum

Building a forge from a brake drum is a rewarding project for blacksmiths and metalworkers looking to create their own tools and sculptures. Brake drums, made of cast iron or steel, provide an excellent heat-retaining structure for forging metal. In this guide, we will go through the essential steps and tools needed to create a functional forge from a brake drum.

Materials Needed

1. Brake Drum Obtain an old brake drum from a vehicle. These can often be found at scrap yards or through local classifieds. 2. Steel Pipe You’ll need a piece of steel pipe for the air supply, ideally around 1 to 2 inches in diameter. 3. Venturi or Blower A small blower or a Venturi attachment will help supply air to the fire. 4. Fire Bricks or Clay For insulation and to create a base for your forge. 5. Grate A metal grate to allow ash and small debris to fall out. 6. Welding Equipment If you plan to create attachments, a welder will be handy. 7. Safety Gear Always wear gloves, goggles, and a mask when working with metal and fire.

Step-by-Step Instructions

1. Prepare the Brake Drum Clean the brake drum thoroughly, removing any grease or residue. This is crucial for safety and for proper operation. If necessary, sand or grind any rough areas.

2. Create Air Vents Drill holes in the brake drum to fit the steel pipe. These holes will serve as the air intake, allowing you to supply oxygen to the fire. The air supply is essential for reaching higher temperatures, which is necessary for forging.

3. Install the Steel Pipe Insert the steel pipe into one of the holes you drilled. This pipe will connect to your blower or Venturi system. Ensure a snug fit to minimize air leaks.

4. Add Insulation Use fire bricks or clay to line the interior of the brake drum. This insulation will help retain heat and protect the brake drum from thermal cracking.

5. Create a Grate Place a metal grate at the bottom of the mug. This will help keep the charcoal or coal off the bottom, allowing air to flow freely. The grate should fit securely within the drum.

6. Set Up Your Air Supply Connect your blower or Venturi to the steel pipe. Make sure it is securely attached and that there are no air leaks. If you’re using a blower, control the airflow with a switch or throttle.

7. Testing the Forge Once assembled, it’s time to test your forge. Place coal or charcoal in the drum and ignite it. Use your air supply to control the fire’s intensity. Ensure you can maintain a consistent temperature suitable for forging.

8. Safety First Always ensure you have a fire extinguisher nearby, and work in a well-ventilated area. Wearing protective gear is crucial to avoid burns or inhalation of harmful fumes.

9. Start Forging Once your forge is up and running, you can begin heating metal for your projects. Practice your blacksmithing techniques, and soon you’ll be creating your own tools or art pieces.

By following these steps, you can build a functional and efficient forge from a brake drum. This project not only recycles an old part but also provides a valuable tool for your metalworking endeavors. Happy forging!
