How to Build a Forge from a Brake Drum | DIY Forge Guide

Building a forge from a brake drum is an effective way to create a compact and functional workspace for blacksmithing or metalworking. With a few readily available materials and tools, you can transform an old brake drum into a powerful forge. Here’s how to do it.

Materials Needed

1. Brake drum 2. Firebricks or refractory cement 3. Metal pipes (for air supply) 4. Blower or hairdryer 5. Steel or iron for the legs and frame 6. High-temperature paint (optional) 7. Basic tools (wrenches, screwdrivers, etc.)

Step-by-Step Guide

1. Choose the Right Brake Drum Start by selecting a robust brake drum, preferably one that is made of cast iron or steel. Ensure that it is in good condition with no significant cracks or damage.

2. Prepare the Drum Clean the brake drum thoroughly to remove any rust, dirt, or grease. You can use a wire brush or sandpaper for this. If desired, paint the outside with high-temperature paint to enhance durability and aesthetic appeal.

3. Create an Air Supply System The primary function of the forge is to provide heat, which means you’ll need a reliable air source. Use a metal pipe to create a tuyere (air inlet). Drill a hole in the side of the brake drum, just below its rim, and insert the pipe. This pipe will connect to a blower or hairdryer that will supply air to the forge, increasing combustion and raising the temperature.

4. Install Firebrick or Refractory Cement To retain heat and protect the brake drum, line the inside with firebricks or apply refractory cement. This step is crucial as it helps keep your forge at high temperatures. Make sure the lining is thick enough to withstand the heat from the burning coal or other fuel.

5. Set Up a Firing Area After preparing the interior, place a small layer of charcoal, coal, or coke in the bottom of the drum. The air from the blower will help ignite the fuel and maintain the fire.

6. Add Legs and Frame To elevate your forge to a comfortable working height, attach sturdy legs made of steel or iron to the brake drum. Ensure that the structure is stable and can support the weight of the drum while being used.

7. Test Your Forge Finally, test your forge by turning on the blower and adding fuel. Make adjustments as necessary to ensure a consistent flow of air and a steady burn.

With a little bit of effort and creativity, you can successfully build a functional forge from a brake drum. This project not only recycles an old part but also provides an invaluable tool for your metalworking endeavors. Happy forging!
