Materials You Will Need
- Steel drum (55-gallon)
- Angle grinder
- Drill with metal bits
- Measuring tape
- Chalk or marker
- Fireproof silicone sealant
- Duct tape
- High-temperature paint
- Wire rack or grate
- Thermometer
Step 1: Preparing the Drum
Begin by cleaning the steel drum to remove any residual chemicals or debris. Use hot soapy water and a stiff brush to scrub the interior and exterior of the drum thoroughly. Rinse it well and let it dry completely.
Step 2: Marking the Opening
Measure and mark a square at the bottom of the drum for the chimney opening. A size of 12 x 12 inches is generally suitable, but you can adjust it according to your preference. Ensure that the opening is at least 6 inches above the bottom of the drum to allow for proper airflow.
Step 3: Cutting the Opening
Put on safety goggles, gloves, and a face mask to protect yourself from metal shavings. Use an angle grinder to carefully cut along the marked lines. Take your time to create a clean and precise cut to ensure a proper fit for the chimney pipe.
Step 4: Installing the Chimney Pipe
Apply a layer of fireproof silicone sealant around the edges of the opening to create an airtight seal. Insert the chimney pipe into the opening and secure it with duct tape. Allow the silicone to dry as per the manufacturer’s instructions before moving on to the next step.
Step 5: Adding Ventilation Holes
Drill several small ventilation holes around the lower section of the drum to allow air to flow into the smoker. These holes will help regulate the temperature inside the chamber. Be mindful of spacing the holes adequately to ensure consistent airflow.
Step 6: Applying High-Temperature Paint
Apply a coat of high-temperature paint to the exterior of the drum. This will help protect it from rust and extend its lifespan. Allow the paint to dry completely before proceeding.
Step 7: Adding Cooking Grates and Thermometer
Place a wire rack or grate inside the drum, about halfway up from the bottom. This will serve as the cooking surface for your meats. Install a thermometer on the lid of the drum to monitor the internal temperature accurately.
Step 8: Testing and Seasoning
Before using your newly constructed BBQ chimney, it’s essential to season it. Start by starting a small fire inside the drum and let it burn for a few hours. This will eliminate any lingering odors or residue and prepare the smoker for its first cooking session. Monitor the temperature using the installed thermometer to ensure it remains within your desired range.
Now that you have successfully built your own BBQ chimney, get ready to take your smoking skills to new heights. Experiment with different wood types and recipes to create mouthwatering, smoky masterpieces that will impress your friends and family. Happy barbecuing!
