If you’ve never built a forge before, you might want to check out this tutorial, especially if you’re interested in blacksmithing. Maybe you’ve tried to build a forge before but gave up because it was too complicated. 

The idea behind a forge is that you can make your own metal into a wide variety of objects, like horseshoes, hinges, and even the metal in your car. 

You can also make the tools that you need for metalworking. The process of creating these tools is called forging. Follow our step-by-step tutorial on how to make a forge.

A blacksmithing forge is a metal or ceramic container in which you can melt iron and other metal alloys and weld them together. A blacksmithing forge is used by blacksmiths and metalworkers to weld metal pieces together in a controlled, efficient way.

How Does a Forge Work?

A forge is a tool that uses fire and air to melt metal. The heat is controlled by a source such as propane, wood, etc. There are many different types of forges ranging from the small backyard model to the huge industrial furnace that can melt tons of metal in a short amount of time, but the basic idea is simple.

Step-by-Step Guide To Make a Homemade Forge

Gather Your materials

Things You’ll Need:

  • Chisel
  • Hammer
  • Firebricks
  • Burner
  • Cardboard

Build the Forge Body

Get Firebricks That Are the Right Kind of Thickness

Note: It’s recommended to use ceramic bricks if you can get them. They are much more durable and can take on a lot more heat than conventional firebricks. 

Conventional firebricks, while great for maintaining heat, just aren’t of the same quality as their ceramic counterparts. 

Cutting the Firebricks Into Two Rectangular Shapes of Equal Sizes

Form the base around the two rectangular shapes. common measurements are 2-½ inches, 4 inches, and 5 inches The back of the square should face the firebricks. 

It’s important to get the bricks as equal in measurement as possible. This helps to make your forge have an even heating area. It also helps the bricks last longer. 

Cut Out Rectangular Templates That Will Form the Cavity of the Forge and Trace It Out on the Firebrick

If you want you can glue some scrap pieces of wood into the middle of the template with a 2-¼ inch distance  Smooth down the face of the template to achieve the smooth surface required for the forge 

Use a Hammer and Chisel To Cut Out the Cavity in the Firebricks

The first thing you will need to do is locate and prepare a suitable bit for your forge. Use a fine flake or arrow point (the best choice) Some bits can be easily modified for a smaller bit, if desired, using a file or hammer on a scrap piece. 

Chiseling accurately with a chisel requires skill and practice, but can be done more easily when you are more familiar with the tool and work with soft materials.


Mark the Center of the Firebrick Where You Want To Make the Drill and Start Drilling Appropriately

Drill a hole into the firebrick. Replace the brick with the appropriate center. Repeat the process with the next firebricks.

Keep Drilling Until You Have an Almost Perfect Inlet Hole

You want to press heat out of the forge as quickly as possible. it’s imperative that you have a well-centered hole for the fan to sit in. Drill as far as you need the hole to be, without any hesitation. 

Set Up the Burners

The size of the burners depends on what you’ll be doing with it. As long as they fit your connections you’ll be good to go. 

It’s recommended to get burners that are capable of burning at a higher temperature than you actually need. 

Finishing Touches

It’s the Little Things That’ll Make Your Forging Experience Better:

  • Make sure your propane connector is properly secured 
  • Place your wood in a safe location.
  • See if there are ways to enhance the heat insulation

Make Your Ventilation

Ventilation is a big deal in forges, whether you are making a large forge or a forge with many different pieces of metal being heated up. You may benefit from having holes for the smoke to escape. 

A good rule of thumb is to make your forges with enough holes so as to not have your air blocked.

Lastly, always make sure your ventilation doesn’t cut off all air in the room. You’ll need to get rid of any poisonous gases while you are working.

Frequently Asked Questions

Can You Be a Blacksmith Without a Forge?

Can you be a blacksmith without a forge? Yes, but it’s not a particularly great idea, as you’ll need a high and stable heat source to properly melt your metal.

Is Blacksmithing an Expensive Hobby?

Is blacksmithing an expensive hobby? Yes and no. You can easily get started if you have the materials, but expect to spend anywhere between $2000-$5000 initially. 


And now you know how to make a forge. We hope you enjoyed our step by step tutorial. Forging is a really great way for you to explore your metal-building passion. Enjoy your new forge and have fun.
