How to Make a Brake Drum Forge

Creating your own brake drum forge can be a rewarding project, allowing you to forge steel and create custom metal components. Brake drums, common in automotive applications, can be repurposed to serve as an effective forge when combined with the right materials and methods. This guide will walk you through the steps to construct a brake drum forge.

Materials Needed

Before you begin, gather the necessary materials

1. Brake Drum A used brake drum can often be found at scrap yards. Ensure it is in good condition, with no significant rust or damage. 2. Steel Plate A thick steel plate will serve as the base for your forge. This plate needs to be sturdy enough to withstand high temperatures. 3. Fire Bricks These will help insulate the forge and contain the heat.

4. Burner You can use a propane burner or a coal burner, depending on your preference. Propane is generally easier to manage, while coal can reach higher temperatures.

5. Insulation Material Kaowool or ceramic fiber insulation will help maintain heat within the forge.

6. Tools You will need tools such as wrenches, screwdrivers, a drill, and a cutting tool to modify the brake drum and install the burner.

Step-by-Step Construction

Step 1 Prepare the Brake Drum

Start by cleaning the brake drum thoroughly. Use a wire brush to remove any debris and rust. This is important as leftover brake dust can be harmful when heated.

Once cleaned, you may want to cut an opening into the drum to accommodate the burner. This opening will typically be about 2 to 3 inches in diameter and should be positioned on the side where the flame will enter.

Step 2 Install the Burner

Place the burner in the hole cut into the brake drum. If using a propane burner, ensure that it fits snugly and is aimed towards the center of the drum. You can use high-temperature silicone or metal brackets to secure the burner in place.

If you’re using a coal burner, make sure it is positioned to allow proper airflow and combustion. This may involve elevating the burner slightly to prevent clogging from ash.

Step 3 Insulate the Forge

After installing the burner, line the interior of the brake drum with insulation. Ensure that it covers the entire inner surface, as this will help maintain the forge's temperature by minimizing heat loss. If using fire bricks, arrange them in a way that forms a rough bowl shape at the bottom of the drum where you will place your metal pieces.

Step 4 Create a Base

To create a stable base for your forge, place the brake drum on a thick steel plate. This plate should be large enough to support the entire drum and protect your work surface from the heat generated by the forge.

You can elevate the drum by placing it on concrete blocks or steel legs to make working with it easier – just be cautious about the heat transmission.

Step 5 Test the Forge

Before proceeding with any forging work, test the forge by firing it up. Check for any gas leaks if you are using propane and ensure that air is flowing properly if using a coal burner. Allow the forge to heat up for 15-30 minutes and monitor the temperature inside. A properly built brake drum forge should reach temperatures around 1,500°F (815°C), which is suitable for forging most steel alloys.

Step 6 Start Forging

Once the forge is at the desired temperature, you can start forging your metal. Make sure to wear appropriate safety gear, including gloves, goggles, and a face shield, to protect yourself from sparks and hot metal.

Conclusion

Constructing a brake drum forge is an accessible and effective way to create a versatile metalworking tool. With the right materials and steps, you will be well on your way to forging your own metal projects. Remember to prioritize safety throughout the process, and you will enjoy the art of metalworking with your new forge. Happy forging!
