How Do You Make a Burn Barrel? Fuel Oil Tank Hacks for Woodworkers

Turning an old fuel oil tank into a burn barrel is a fantastic way to recycle and create a useful tool for your woodworking or logging site. I’ve built several of these over the years, and they’ve proven to be incredibly durable and efficient. The process involves careful preparation, cutting, ventilation, and safety measures. In this guide, I’ll walk you through each step, sharing my personal insights and tips to ensure you create a burn barrel that’s both safe and effective.

Preparing the Fuel Oil Tank

Before you even think about cutting into a fuel oil tank, safety is paramount. Fuel oil residue can be highly flammable, and any remaining vapors can cause an explosion. Trust me, I once rushed this step and ended up with a small, but frightening, flare-up.

Emptying and Cleaning the Tank

Drain Any Remaining Oil: The first step is to completely drain the tank. Use a siphon or pump to remove any remaining fuel oil. Dispose of the oil properly according to local regulations. Never pour it down a drain or onto the ground.
Vent the Tank: Remove any access ports or fittings and allow the tank to vent for several days. This will help dissipate any remaining vapors. I usually leave it for at least a week, depending on the weather.
Thoroughly Clean the Interior: This is the most critical step. Use a strong detergent and water to scrub the inside of the tank. A pressure washer can be very effective. Repeat this process several times until you are confident that all residue has been removed.
Steam Cleaning (Recommended): If possible, steam cleaning the tank is the best way to ensure it’s completely clean. The high temperature of the steam will help remove any stubborn residue and vapors. Many professional cleaning services offer this.

Personal Story: I remember one time, I thought I had cleaned a tank well enough, but when I started cutting, I still detected a faint odor of fuel oil. I immediately stopped and repeated the cleaning process. It’s always better to be safe than sorry.

Assessing the Tank’s Condition

Check for Rust and Weak Spots: Examine the tank for any signs of significant rust or corrosion. If the tank is too deteriorated, it may not be safe to use as a burn barrel.
Ensure Structural Integrity: Make sure the tank is structurally sound. Any major dents or deformities can compromise its stability.

Tip: A good way to check for weak spots is to tap the tank with a hammer. A solid sound indicates good metal, while a dull thud suggests corrosion.

Tools and Materials Required

Before you begin the transformation, gather all the necessary tools and materials. Having everything on hand will make the process smoother and safer.

Cutting the Tank

Carefully planned cuts are essential for creating a functional and safe burn barrel. Here’s how I approach this step.

Planning the Cuts

Determine the Size of the Opening: Decide how large you want the opening to be for adding materials to the burn barrel. I usually aim for an opening that’s about one-third of the tank’s total surface area.
Mark the Cutting Lines: Use a measuring tape and marker to draw clear cutting lines on the tank. Ensure the lines are straight and even.
Plan for a Door (Optional): If you want a door for easier access, mark the area for the door and the hinges.

Making the Cuts

Start with Pilot Cuts: Begin by making small pilot cuts along your marked lines. This will help guide your cutting tool and prevent it from slipping.
Follow the Cutting Lines: Carefully follow the cutting lines with your chosen cutting tool. Take your time and make sure the cuts are clean and precise.
Cut Out the Opening: Once you’ve completed the cuts, remove the section of the tank to create the opening.
Create a Door (Optional): If you’re adding a door, cut out the door section and attach hinges using a welder or bolts.

Safety First: Always wear safety glasses, gloves, and a respirator when cutting metal. Metal shards can fly off at high speeds and cause serious injury.

Adding Ventilation

Proper ventilation is crucial for efficient burning. Without enough airflow, the fire will smolder and produce excessive smoke.

Creating a Base and Support

Elevating the burn barrel helps improve airflow and prevents the bottom of the tank from rusting prematurely.

Using Concrete Blocks or Bricks

Prepare the Ground: Choose a level and non-flammable surface for the burn barrel. Clear away any vegetation or debris.
Place the Blocks or Bricks: Arrange the concrete blocks or bricks in a square or rectangle to create a stable base.
Position the Burn Barrel: Carefully lift the burn barrel and place it on top of the base.

Adding Metal Legs (Optional)

Weld Legs to the Tank: If you’re using metal legs, weld them to the bottom of the tank. Ensure the legs are evenly spaced and provide good support.
Reinforce the Legs: For added stability, you can weld cross braces between the legs.

Base Recommendation: Concrete blocks are a simple and effective way to elevate the burn barrel. However, if you want a more permanent and stable solution, metal legs are a great option.

Adding a Grate (Optional)

A grate inside the burn barrel can improve airflow and make it easier to remove ashes.

Fabricating the Grate

Measure the Inside of the Tank: Measure the inside diameter of the tank to determine the size of the grate.
Cut Metal Bars or Mesh: Cut metal bars or mesh to fit inside the tank.
Weld the Grate Together: Weld the metal bars or mesh together to create a grate.

Installing the Grate

Weld Supports Inside the Tank: Weld metal supports inside the tank to hold the grate.
Place the Grate on the Supports: Place the grate on top of the supports. Ensure it is stable and level.

Grate Tip: A grate not only improves airflow but also makes it much easier to clean out the ashes. I’ve found that a grate made from heavy-duty metal mesh works best.

Painting the Burn Barrel (Optional)

Painting the burn barrel with high-temperature paint can help protect it from rust and heat damage.

Preparing the Surface

Clean the Exterior: Use a wire brush or sandpaper to remove any rust or debris from the exterior of the tank.
Wipe Down the Surface: Wipe down the surface with a clean cloth to remove any dust or grease.

Applying the Paint

Apply Primer (Optional): Apply a coat of high-temperature primer to the exterior of the tank. This will help the paint adhere better.
Apply the Paint: Apply several coats of high-temperature paint, allowing each coat to dry before applying the next.

Paint Recommendation: High-temperature paint is essential for protecting the burn barrel from the extreme heat. I recommend using a paint specifically designed for stoves or grills.

Safety Precautions

Safety is paramount when using a burn barrel. Here are some essential safety precautions to keep in mind.

Location: Place the burn barrel in a clear area, away from buildings, trees, and other flammable materials.
Supervision: Never leave a burning barrel unattended. Always supervise the fire and keep a close eye on it.
Water Source: Keep a water source nearby, such as a hose or buckets of water, in case of emergencies.
Fire Extinguisher: Have a fire extinguisher readily available.
Burning Restrictions: Check local regulations and burning restrictions before using the burn barrel.
Safe Materials: Only burn appropriate materials, such as wood scraps, paper, and cardboard. Never burn hazardous materials like plastics, rubber, or chemicals.
Protective Gear: Always wear safety glasses, gloves, and a respirator when using the burn barrel.

Safety Story: I once witnessed a small brush fire start when embers escaped from a burn barrel that wasn’t properly ventilated. Luckily, we were able to extinguish it quickly with a hose. This experience taught me the importance of taking safety precautions seriously.
