This guide will walk you through the entire process, from planning and design to construction and use. Follow along to learn how to build your own custom BBQ pit smoker from scratch.
Planning Your BBQ Pit Smoker Build
The first step is to decide on the size, shape, and features of the smoker you want to build. Consider the following factors:
Type of Smoker
There are several styles of smokers to choose from:
- Offset smoker – The heat and smoke source are offset to the side of the main cooking chamber. Allows for indirect smoking.
- Barrel smoker – Made from an entire 55-gallon metal drum. Simple and inexpensive.
- Brick or cinder block pit – Masonry chamber surrounded by an offset firebox. Holds heat well.
- Cabinet smoker – Insulated upright design with multiple racks. Ideal for cold climates.
Size and Capacity
Determine how much grilling space you’ll need and how many people you want to cook for regularly. A larger smoker allows you to smoke more food at once.
Fuel Type
Select charcoal, wood, gas, or electric as your heat and smoke source. Each has pros and cons regarding temperature control, smoke flavor, and ease of use.
Materials
Choose durable, high-heat materials like steel, concrete, and fire bricks. Avoid potentially toxic paints or coatings inside the cooking chamber.
Additional Features
Consider creative touches like racks, shelves, storage, work tables, thermometers, wheels for mobility, and more.
Designing and Building Your Smoker
Once you’ve settled on the type of pit smoker you want, it’s time to map out the design and start gathering supplies.
Required Materials
Here are the main components you’ll need to source:
- Cooking chamber – Typically a steel drum, smoke vault, brick enclosure, ceramic cooker, etc.
- Firebox – Attached offset box to hold the fire and wood/charcoal for generating smoke.
- Lid – Access door to seal in smoke and heat while cooking.
- Grate – Chrome-plated grill racks placed above the fire.
- Chimney – Vertical smokestack to vent smoke and control air flow.
- Temperature gauge – Dial thermometer to monitor internal temp.
- Seals – High-temp silicone and insulation around lids and doors.
Design Plans
Draft careful plans showing the smoker layout, dimensions, and construction order. Sketch ideas and make changes until you’re satisfied.
Begin Construction
With materials gathered and plans in hand, you’re ready to start assembly. Have proper welding, drilling, and metalworking tools on hand. Take time to carefully construct each component.
Finishing Touches
Once built, add aesthetic touches like paint, decorative hardware, lights, storage, and more to customize your smoker.
Smoker Materials and Equipment
Having the right materials on hand will make the building process easier and ensure top-notch results. Here are some of the key items you’ll need:
Primary Cooking Chamber
This is the main vessel that food smokes in. Good options include:

- Large metal tank – Propane tanks, water heaters, filing cabinets, etc can work.
- Masonry – Brick, concrete block, and tile hold heat consistently.
- Refractory ceramic materials – Withstand very high temperatures.
Firebox and Chimney
Typically made from similar metals and materials as the main chamber. Insulate around the firebox.
Grates
- Chrome-plated steel grill racks are durable and easy to clean.
- Welded round rods or expanded metal sheets also work.
- Avoid painted grates that can chip and flake.
Thermometers
- Dial thermometers let you monitor internal pit temps.
- Probe thermometers check food and smoker temps.
- Infrared thermometer guns for quick external readings.
Seals and Insulation
- High-temp silicone withstands 500oF+ temps around lids.
- Kaowool blanket lining protects fireboxes and exteriors.
- Reflectix or rockwool forminimal heat loss.
Hardware and Supports
- Angle iron, bracing, bolts, hinges, latches, casters, handles and more.
Tools
- Welder, drill, grinder, saw, wrench set, pliers, clamps, and safety gear.
Constructing an Offset Smoker
One of the most popular homemade smoker designs is the offset smoker. Here is an overview of how to build one:
Step 1: Acquire a Metal Drum
- 55 gallon drums are a convenient cooking chamber size.
- Ensure it is food safe with no interior paint or coatings.
- Remove the lid for access.
Step 2: Attach the Firebox
- Weld a heat-safe metal firebox onto the lower side of the drum.
- Line with insulation so heat radiates into the cooking chamber.
Step 3: Add the Chimney
- Install a vertical smokestack on the opposite end of the firebox.
- This vents heat and smoke. Use adjustable dampers to control airflow.
Step 4: Install Grates
- Add 2-3 sturdy chrome cooking grates inside the chamber.
- These hold the food for smoking.
Step 5: Add Components
- Bolt on handles, thermometers, shelves, storage drawers, etc.
- Paint and label exteriors as desired.
Smoker Tips and Techniques
Once your smoker build is complete, it’s time to fire it up! Follow these tips for the best results:
- Season the smoker – Cure new smokers before first use to minimize metallic flavors. Oil interior and burn wood for 4-6 hours.
- Start with a small fire – Gradually increase temperature, don’t immediately stoke a large fire.
- Keep intake vents fully open – This allows oxygen for clean combustion and good smoke.
- Learn to control the damper – Adjusting the chimney damper regulates temperature and smoke.
- Maintain steady low temps – From 225-275°F is ideal for true smoke cooking rather than just grilling.
- Use a thermometer – Monitor internal pit and food temps for precision cooking.
- Add smoke wood chunks – Experiment with different hardwoods like hickory, apple, mesquite and maple.
- Minimize opening the smoker – This preserves interior heat and smoke levels.
- Let the smoker rest – Allow 10-15 minutes after cooking for coals to fully extinguish before cleaning.
Smoking Woods for Different Flavors
Choosing the right smoldering woods can infuse your BBQ with delicious subtle flavors. Try these varieties:
Hickory
The classic BBQ wood. Provides a robust, smokey flavor. Great with pork, ribs, and poultry.
Mesquite
Dense wood that burns hot and quick. Adds an earthy spice flavor. Ideal for steak and lamb.
Apple
Mildly sweet fruitwood. Mix with other woods or use alone. Goes well with fish and chicken.
Maple
Has a mellow, smoky-sweetness. Pairs nicely with poultry, ham, and sausage.
Oak
Burns steadily with a delicate flavor profile. Works with most meats and bigger cuts.
Cherry
Emits a slightly fruity aroma. Excellent for lending a sweet note to pork or game.
Pecan
Has a mild nutty undertone. Great for pairing with brisket, ribs and chicken.
Experiment to find your favorite smoke woods and combinations. Soak chips in water first for milder smoke.
