How to Make a Brake Drum Forge

Forging is a traditional method that involves shaping metal using compressive forces. One of the most versatile and accessible methods for home blacksmiths is to create a forge from a brake drum. Brake drums are sturdy and heat-resistant, making them ideal for high-temperature metalworking. In this article, we will walk you through the steps to make a brake drum forge, allowing you to embark on your metalworking journey.

Materials Needed

Before you begin, gather the following materials

1. Brake Drum You can salvage a used brake drum from a junkyard or purchase one from an auto parts store. Make sure it’s intact and in good condition. 2. Steel Pipe A piece of steel pipe (approximately 1.5 to 2 inches in diameter) will serve as the air inlet. 3. Blower A small handheld hair dryer or an electric blower can supply the necessary airflow to maintain a consistent temperature. 4. Fire Brick This will help insulate the brake drum and retain heat more effectively. 5. Refractory Cement Optional, for more advanced insulation. 6. Garden Hose Connector To attach the blower to the pipe. 7. Metal Stand To elevate the brake drum off the ground.

Steps to Create the Forge

1. Prepare the Brake Drum Start by cleaning the brake drum thoroughly. Remove any dirt, grease, or debris. If it has paint, use a wire brush or grinder to remove it, ensuring a clean metal surface.

2. Create an Air Inlet Drill a hole in the brake drum near the bottom. This hole should match the diameter of your steel pipe. Insert the steel pipe into the hole so that it extends outward, allowing you to connect the blower.

3. Connect the Blower Using the garden hose connector, attach your blower to the end of the steel pipe. This setup will force air into the combustion chamber, helping to increase the temperature within the forge.

4. Insulate with Fire Brick Line the inside of the brake drum with fire bricks. This insulation helps retain heat and prevents the drum from warping under high temperatures. If you want to enhance durability, use refractory cement to bind the bricks in place.

5. Build the Coal Bed At the bottom of the drum, create a bed of charcoal or coal. This will serve as your fuel source. Make sure to leave ample space for airflow from the pipe to circulate through the fuel bed.

6. Add a Safety Stand Elevate your brake drum forge using a metal stand to ensure stability and safety while working. This also provides you with a comfortable working height to access your materials easily.

7. Testing the Forge Before starting any major projects, perform a test run of your forge. Ignite the coal and turn on the blower to observe the airflow and heat production. Adjust the blower’s speed to ensure proper combustion and reach the desired temperature.

8. Start Forging Once your forge is operational, you can start your metalworking projects! Always remember to prioritize safety by wearing appropriate protective gear and working in a well-ventilated area.

Conclusion

Creating a brake drum forge is a rewarding project that can significantly enhance your metalworking capabilities. Whether you’re making tools, crafting art pieces, or repairing items, having your own forge opens up a world of possibilities. With the right materials and some dedication, you’ll be well on your way to becoming a proficient blacksmith. Happy forging!
