10 Easy Steps on How to Build a Rocket Stove Out of Square Tubing

Step 1: Cut the Square Tubing

The first step is to cut your square tubing into four pieces of equal length. These will serve as the legs for your stove. If you are new to using a metal cutting saw, make sure to follow all safety precautions and ask for assistance if needed.

Step 2: Drill the Holes

After cutting the square tubing, you’ll need to drill holes in them to allow for airflow within the stove. Select a metal drill bit corresponding to the size of the square tubing you’ve chosen. Carefully mark where you want the holes to be on each of the four pieces of tubing.

Remember, precisely positioning these holes is crucial for the stove’s performance, so take your time and measure twice. Once you’ve marked the spots, proceed to drill the holes. Always wear safety glasses and gloves while drilling to prevent any injuries.

Step 3: Weld the Legs Together

Now it’s time to assemble the frame of your rocket stove. Using your welding equipment, carefully weld the four pieces of square tubing together at their ends to form a square. This will create a stable base for your stove. It’s crucial to ensure a strong weld as it will determine the durability of your stove.

It's Crucial to Ensure a Strong Weld

If you’re new to welding, don’t hesitate to ask for help or take a welding class to ensure your safety and the quality of your work. Remember to wear appropriate protective gear, including a welding helmet, gloves, and protective clothing, before welding.

Step 4: Build the Burning Chamber

The next step involves constructing the burning chamber, which will house the fuel for your rocket stove. Cut another piece of square tubing; this will be the height of your stove. Weld it perpendicularly to the assembled base, creating an L-shape. Ensure the weld is strong and secure.

The vertical part of the L will serve as the chimney, while the horizontal will be the feeding tube where fuel is inserted. Ensure the burning chamber aligns with the holes you drilled earlier to facilitate efficient airflow, which is crucial for the stove’s performance. Always remember to wear your safety gear during this process.

Step 5: Create the Air Intake and Fuel Feed

The fifth step involves modifying the horizontal square tube that forms part of the L-shape. This tube will serve two purposes: it will allow air to flow into the stove, and it will also be the opening through which you insert fuel. To create the air intake, cut a square hole on one side of the tube, near the junction where it meets the chimney.

Ensure that this hole is large enough to allow adequate airflow but small enough to prevent fuel from falling out. Cut a larger opening at the other end of the tube for the fuel feed. This is where you will insert the fuel (wood, biomass, etc.) when using the stove. Again, safety comes first, so remember to wear your protective gear while cutting the metal.

Step 6: Assemble the Internal Shelf

The sixth step involves building an internal shelf within the fuel feed tube to hold the fuel above the air intake. This ensures efficient combustion by allowing air to flow beneath the fuel.

Cut a piece of square tubing that fits inside the fuel feed tube to do this. This piece should be long enough to reach from the back of the fuel feed tube to the front of the air intake. Weld this piece into place, ensuring it is level and secure. Remember to use your protective gear while welding.

Step 7: Weld the Top Plate

The seventh step involves welding a square plate onto the top of your rocket stove. This will serve as the cooking surface. Cut a piece of steel sheet to size, ensuring it is slightly larger than the top of the chimney tubing to provide a stable surface for pots and pans.

Center the cut plate over the top of the chimney and weld it into place. Ensure the welding is strong and secure as this surface will be subjected to significant heat when the stove is used. Make sure to wear your safety gear during this step.

Step 8: Clean and Smooth the Surfaces

After all the welding and assembly, your rocket stove may have rough edges or residual welding materials. The eighth step involves using sandpaper or a wire brush to clean and smooth all surfaces.

Pay particular attention to areas where there might be sharp edges or any potential hazards. This not only improves the stove’s overall appearance but also helps ensure your safety when using the stove. Always use gloves with sandpaper or a wire brush to protect your hands.

Step 9: Apply High Temperature Paint (Optional)

The ninth step is optional but can add an aesthetic touch to your rocket stove while also offering additional protection. Apply high temperature paint to your stove. This paint is designed to withstand the high heat your stove will generate and can help prevent rusting over time.

You can choose any color you like, but remember that darker colors will show soot and burn marks less than lighter ones. Apply the paint in a well-ventilated area and allow it to fully dry before using the stove.

Step 10: Test Your Rocket Stove

Finally, the tenth step is to test your newly built rocket stove. To do this, light some small pieces of wood or biomass into the fuel feed tube. The stove should draw air in through the air intake, feeding the fire and sending the flames up the chimney.

Light Some Small Pieces of Wood

If everything works correctly, you should see a strong, steady flame coming out of the chimney. Congratulations, you have successfully built a rocket stove out of square tubing! Always use your rocket stove outdoors in a well-ventilated area and on a non-flammable surface.

By following these simple steps and using the suitable materials, you can build your very own rocket stove out of square tubing. Rocket stoves are a great way to reduce your carbon footprint and save on fuel costs while providing a reliable heat source for outdoor cooking or heating.
