I have always been fascinated by wood-burning ovens. The delicious aroma of freshly baked bread or the crispy crust of a pizza straight out of the oven is simply irresistible. So, when I stumbled upon the idea of making my own wood-burning oven using a microwave transformer, I couldn’t resist giving it a try. Little did I know that this DIY project would not only be rewarding but also a fun and educational experience. In this article, I will guide you through the step-by-step process of making a wood-burning oven using a microwave transformer.
Gathering the Materials
Before we get started, it’s important to gather all the necessary materials. Here’s a list to get you started:

Building the Oven
Now that you have all the necessary materials, let’s dive into the process of building your wood-burning oven.
Step 1: Dismantle the Microwave Transformer
Firstly, you need to dismantle the microwave transformer. Please note that this can be potentially dangerous, so it’s crucial to take all necessary safety precautions. Make sure to wear gloves, safety goggles, and a mask before you begin.
Use an angle grinder with a cutting wheel to cut through the metal casing of the microwave transformer. Be careful not to damage the internal components of the transformer. Once the casing is removed, you should see the primary and secondary windings of the transformer.
Step 2: Remove the Secondary Winding
Carefully remove the secondary winding by cutting the wires connected to it. This will leave you with the primary winding, which will serve as the heating element for your wood-burning oven.
Step 3: Construct the Oven Chamber
Using firebricks, build the walls and the floor of the oven chamber. Firebricks are essential because they are designed to withstand high temperatures. Use heat-resistant mortar to secure the bricks in place. Ensure that the walls are at least 2 to 3 layers thick to provide adequate insulation.
Step 4: Create the Oven Enclosure
Next, you need to construct an enclosure for the oven using plywood or metal sheets. The enclosure will serve as the outer shell, providing insulation and keeping the heat inside. If you opt for plywood, make sure to line the interior with a heat-resistant material like ceramic fiber or vermiculite.
Step 5: Add Reinforcement
To reinforce the oven, attach steel angle iron along the corners and edges of the enclosure. This will add strength and stability to the structure.
Step 6: Install the Heating Element
Now comes the exciting part – installing the heating element. Place the primary winding of the microwave transformer inside the oven chamber. Make sure the winding is centered and securely positioned. Welding it to the steel angle iron is recommended for added stability.
Step 7: Insulate the Oven
To ensure maximum heat retention, fill the gap between the oven chamber and the enclosure with insulation material such as ceramic fiber or vermiculite. This will prevent heat from escaping and maintain a consistent temperature inside the oven.
Step 8: Create the Oven Door
Construct a door for your oven using firebricks and heat-resistant mortar. It’s important to note that the door should fit snugly to prevent heat loss. You may also consider adding a thermometer to monitor the internal temperature of the oven accurately.
Step 9: Finishing Touches
Lastly, add a layer of heat-resistant paint to the outer surface of the enclosure for a polished and professional look. This step is optional but can enhance the aesthetics of your wood-burning oven.
Firing Up Your Wood-Burning Oven
Now that your wood-burning oven is complete, it’s time to fire it up and start cooking!
To start, place metal grating or wire mesh on the floor of the oven chamber to provide airflow and support for the wood. Next, add a layer of lava rocks or clay balls on top of the grating to distribute and retain the heat effectively.
Light a fire using small pieces of dry, seasoned wood. Gradually add larger pieces of wood as the fire builds. Allow the oven to heat up for at least an hour, reaching the desired cooking temperature.
Once the oven is hot, you can start baking bread, pizza, or any other delicious treats you desire. Just make sure to monitor the temperature using the thermometer and adjust the fire accordingly.
Conclusion
Building your own wood-burning oven using a microwave transformer is a fulfilling and rewarding experience. It not only allows you to enjoy the incredible flavors of wood-fired cooking but also offers a sense of accomplishment in creating something with your own hands.
Remember, safety should always be a priority when working with high temperatures and electrical components. Take necessary precautions, follow the steps carefully, and enjoy the delicious and authentic culinary creations that your homemade oven can produce. Happy baking!
