How to Build a Backyard Forge: Your Guide to DIY Blacksmithing

For those interested in metalworking and blacksmithing, building a backyard forge is an excellent way to start your blacksmithing journey. This guide will help you create a forge suitable for either natural gas or coal-burning methods. We'll cover the materials required, construction steps, and safety tips to ensure you have a safe and effective forging environment.

The Basics of Building a Backyard Forge

Whether you want to use natural gas or coal, building your forge from scratch involves a series of steps that require careful planning and execution. Below, you'll find detailed instructions on how to build both types of forges, along with important considerations for safety and efficiency.

For Gas-Driven Forges

If you prefer a gas-driven forge, the process is straightforward. You can either buy a large burner or attempt to build one yourself, but we recommend purchasing a pre-made burner due to the potential costs in parts and materials. A gas burner is mounted in an open-ended box made of refractory brick. The workpiece can be inserted from either end, providing flexibility in your forging process.

Step-by-Step Guide to Building a Gas-Driven Forge

Buy a suitable gas burner. Create a box using refractory brick and mount the burner in the box. Ensure the box has an open-ended design to allow easy access for workpieces. Connect the gas line and plumbing to integrate the burner into your forge setup.

By following these simple steps, you can create an effective gas-driven forge that won't require extensive DIY experience.

For Coal or Charcoal-Fired Forges

For coal or charcoal forges, the process is a bit more involved due to the need for forced air. You'll need a source of air under slight pressure, which can be achieved either through a motorized blower or a hand-cranked one. Once you have the air system in place, you can start building your forge to any desired configuration.

Step-by-Step Guide to Building a Coal or Charcoal-Fired Forge

Choose a firepot: You can repurpose parts from an old car, such as a brake disc or brake drum, as the firepot. Install a draft control system to regulate airflow. A grid of rebar can serve as an effective screen to prevent coal from falling through. Add refractory bricks to build up the walls around the firepot, creating a deeper firebox if necessary. Mount your air supply piping and ensure a steady flow of air.

Reusing parts from old cars can save you money and add a unique touch to your forge. This method is particularly good for those who prefer a more traditional and rustic forging setup.

Additional Tips and Considerations

For those looking to create a backyard forge, there are several resources available online. YouTube is a treasure trove of instructional videos that can guide you through the process. Make sure to watch multiple videos and select a method that best suits your needs and safety requirements. Remember, forging is a dangerous activity that requires a great deal of skill and caution.

Building My Forge

I built my forge using a truck brake drum, which I turned facing up. I added three steel rod legs and an air pipe that feeds through the hole at the center. I also used a small electric blower to push air through the pipe up into the coal. This setup works well with hard coal and provides a robust and efficient forgery environment.

DIY Blacksmithing Kit for Beginners

To build a backyard forge, you'll need the following basic materials:

A basin for the coal (e.g., old grill, stainless steel sink, or brake drum) A grate for the bottom of the basin to hold the coal in place Piping to direct the airflow (2-inch black pipe is a good choice) An old hair dryer to provide the necessary airflow (an electric blower with variable speed control is preferable) Coal (preferably bituminous or anthracite) or charcoal for fuel

Once you have these materials, follow these steps to assemble your forge:

A visual guide to building a backyard forge is provided in The DIY Blacksmithing Book. This book offers detailed diagrams and explanations that can be particularly helpful for beginners. It provides clear instructions on how to construct your forge using readily available materials and tools.

By following the steps outlined in this guide, you can build a backyard forge that meets your blacksmithing needs. Remember, safety is paramount when working with forges, so always prioritize safety measures and follow all necessary precautions.

Conclusion

Building a backyard forge is a rewarding project for anyone interested in blacksmithing. Whether you choose a gas-driven or coal-fired forge, the process involves a mix of creativity, skill, and patience. With the right materials and a bit of DIY spirit, you can create a functional and efficient forge in your backyard. Happy forging!
