How to Turn a Metal Filing Cabinet into a Smoker
Converting an old metal filing cabinet into a functional smoker can be a fun and satisfying DIY project. With some simple modifications, you can transform a discarded office furniture piece into a useful backyard cooking appliance. Follow these steps to learn how to turn a metal filing cabinet into a smoker in your own backyard.
Supplies Needed
- Metal filing cabinet
- High-temperature spray paint or metal paint
- Heat-resistant sealant
- Saw or jigsaw
- Drill
- Stainless steel screws
- Smoker box or cast iron skillet
- Grill grate
- Chimney extension
- Thermometer
- Heat-resistant gloves
Prepare the Cabinet
The first step is to clean out and prepare the metal filing cabinet. Remove all drawers and interior components so you have an empty cabinet shell to work with. Use a degreaser or soap and water to clean the interior and exterior of the cabinet.
Once cleaned, inspect the cabinet for any holes, gaps, or flaws that could impact heat retention. Seal any problem areas with a high-temp sealant designed for smokers and grills.
Now you can add color by spray painting the cabinet with high-heat spray paint made for grills or metal. opt for a dark color for optimal heat absorption. Allow paint to fully cure before moving to the next steps.
Add Smoke and Heat Sources
Cut an opening in the bottom of the cabinet for airflow using a jigsaw or drill. The hole should be just big enough to accommodate a smoker box or cast iron skillet. This will hold your smoking wood chips or charcoal.
On the top of the cabinet, cut a larger opening for the grill grate. Measure to find the centerpoint and cut a hole a few inches wider than your grate. The grate will sit here to hold food for smoking.
Drill a few holes near the bottom back of the cabinet for airflow. About 4-6 holes around 1 inch in diameter should suffice.
Install Smoker Components
Place your smoker box, skillet, or other heat source in the hole cut in the bottom of the cabinet. Make sure it fits snugly.
Insert the grill grate in the top hole. Use stainless steel screws to secure it in place if needed.
Attach chimney piping to the hole cut in the back of the cabinet. The extension chimney helps ventilate smoke.
Install a thermometer through the side of the cabinet to monitor internal temperature.
Season and Use Your Smoker
Before first use, season the interior following typical smoking/grilling seasoning steps. This involves coating with oil and running a hot fire for ~1 hour.
To use, fill the smoker box with soaked wood chips or charcoal. Keep the fuel source replenished to maintain consistent smoke. Place food on the grill grate, shut the cabinet, and monitor the temperature, adding more fuel as needed.
The filing cabinet’s solid metal construction retains heat well for proper smoking. Enjoy experimenting with different woods and recipes with your DIY smoker. Add shelves or racks inside for increased cooking capacity.
Tips for Success
- Look for a sturdy all-metal cabinet without plastic components
- Use galvanized steel duct pipe for durability
- Choose wood chips/chunks suited for long smoke times
- Soak wood chips 30+ minutes before use
- Keep ample ventilation from intake and exhaust holes
- Bring cabinet interior to 150-225°F for smoking most meats
- Use heat-resistant gloves when handling to avoid burns
Frequently Asked Questions
What size filing cabinet works best?
Standard 2-4 drawer vertical file cabinets around 3-4 feet tall work well. Larger sizes can accommodate more food. Mini cabinets may not hold heat as evenly.
What types of wood produce good smoke?
Fruit woods like apple, cherry, pecan, and alder give milder smoke flavor. Hickory, mesquite, and oak impart a richer, bolder taste. Experiment to find your favorites.
Can I use charcoal instead of wood?
Yes, charcoal can be used in a smoker box or skillet as an alternative or in addition to wood. Add wood chunks for flavor. Manage the airflow to maintain temperatures.
Should I season the smoker even if the cabinet is new?
Yes, seasoning is highly recommended to burn off any residue and prime the metal for even heating. Follow standard grill/smoker seasoning procedures.
How do I prevent rust inside the cabinet?
Proper seasoning helps coat the metal. Always empty ash after use to avoid moisture buildup. Touch up paint as needed, especially on the inside.
