Creating a Forge Using An Old Brake Drum for Blacksmithing Projects

How to Build a Forge from a Brake Drum

Building a forge from a brake drum is a rewarding project that allows blacksmiths and metalworkers to create their own tools and pieces of art. Not only is it cost-effective, but it also provides a sturdy and efficient workspace for heating metal. This guide will help you understand the steps required to transform a simple brake drum into a functional forge.

Materials Needed

1. Brake Drum This will serve as the primary body of the forge. You can find used brake drums at auto repair shops or junkyards. 2. Steel Pipe A length of steel pipe to serve as the air supply. 3. Blower or Fan This will provide the necessary airflow to increase the temperature inside the forge. 4. Firebricks Optional but recommended to line the inside of the brake drum for better heat retention. 5. Metal Grate A grate to support the charcoal or coal while allowing air to flow from below. 6. Heat-Resistant Paint To protect the exterior of the forge. 7. Tools Safety goggles, gloves, a drill, a cutting tool, and basic hand tools.

Step-by-Step Instructions

Step 1 Prepare the Brake Drum

Begin by cleaning the brake drum thoroughly. Remove any dirt, grease, or brake dust. If it’s rusty, consider using a wire brush to scrape it down to bare metal. This will ensure a better surface for heat retention and prevent fumes from contaminants during use.

Step 2 Create Air Supply

Next, you need to create an air supply system. Drill a hole in the side of the brake drum about two inches in diameter. This hole will accommodate the steel pipe, which will act as an air inlet. Make sure the pipe fits snugly and is positioned low enough to allow air to flow directly under the coal or charcoal.

Step 3 Installing the Blower

Attach the blower or fan to the end of the steel pipe. This will force air into the brake drum and increase the forge temperature. If you're using a handheld blower, you may need to devise a method to secure it to the pipe. Make sure the blower is adjustable for better control over airflow.

Step 4 Line the Forge (Optional)

Line the inside of the brake drum with firebricks if you have them. This will help retain heat and protect the drum from burning through. Cut the bricks to fit snugly within the drum, creating a heat-resistant barrier.

Step 5 Add the Grate

Place a metal grate inside the drum above the air inlet. This will support your fuel (coal or charcoal) while allowing air to flow underneath. Ensure that the grate is sturdy enough to hold the weight of the fuel without bending.

Step 6 Paint and Protect

Once your forge is assembled, consider applying heat-resistant paint to the exterior of the brake drum. This will protect against rust and extend the life of your forge. Be sure to follow the manufacturer’s instructions for the paint you choose, and allow it to cure properly before use.

Step 7 Test Your Forge

Finally, it’s time to test your forge. Light some charcoal or coal and observe the airflow from the blower. Adjust the airflow as necessary to reach the desired temperature for your metalworking projects.

Conclusion

Building a forge from a brake drum is a fantastic way to repurpose materials and create a valuable tool for metalworking. With some ingenuity, it’s possible to craft a functional and efficient forge that suits your needs. Always remember to prioritize safety when working with high temperatures and always wear appropriate protective gear. Happy forging!
