Old Fridge Smoker

A cold smoker, also known as a smoking cabinet, is an extremely useful appliance to have.

Unlike conventional smokers, cold smoking accomplishes a multitude of different tasks.

For example, not only can it be used to smoke ham, but you can use it to cold smoke cheese, jerky, and much more! On top of that, you can even utilize it as a warming rack to ensure that your food remains warm. We’ve even tried baking a cake in one of these, and it works!

Materials You Will Need

  • BBQ thermometer
  • Bolts (6 mm)
  • Iron rods
  • Nuts and washers
  • Old fridge
  • Paint
  • Silicone sealant
  • Steel sheet
  • Steep pipe (1 to 2 feet / 30 mm diameter)
  • Wine corks
  • Wooden slats

Tools needed

  • Bench vice
  • Circular cutter
  • Coping saw
  • Cordless drill
  • Hammer
  • Hacksaw
  • Metal filer
  • Screwdriver
  • Sealant gun
  • Tin snips
  • Utility knife

Basic Skills Needed

You’ll need to know how to use a drill, saw, and metal filer.

Guide to Building It

Before you do anything, you’ll want to make sure that the entire fridge is clean; both inside and out. Next, you’ll want to decide on the number and length of your shelves you’ll be installing inside.

Then, you’ll need to cut the metal rods to the appropriate size. Then you’ll want to make and install the chimney pipe; this will let the stream of smoke escape. You’ll need to cover up any unwanted openings with sealant, as well as ensure that the fridge is fireproof.

For your convenience, you might also want to attach a temperature gauge.

Build your An Ugly Drum Smoker (UDS)

A standard DIY item to make BBQ smokers out of is an old oil drum or barrel. A classic drum, or barrel smoker you can buy is the Pit Barrel Cooker.
Why would you pay that much for one when you can easily make a DIY drum smoker at home for way less?

Drum smokers are fantastic because they’re generally faster at smoking meat, and they’re able to hold a lot.

People usually highly recommend smoking brisket, chicken, and ribs in BBQ drum smokers. Here’s how you can make your own ugly drum smoker from scratch!

Materials You Will Need

  • Baling wire
  • Ball valve
  • Bushing (½ inch)
  • Expanded steel
  • Grill lid
  • Handles
  • High-temperature paint
  • Nuts and bolts
  • Oil barrel or stainless steel drum
  • Shelf clips
  • Shelving rail
  • Smaller grill grate
  • Circular grill grate (preferably steel)
  • Washers (M20 and Fender)

Tools Needed

  • Drill
  • Drill bits

Basic Skills Needed

You will need to know how to use a drill.

Guide to Building It

Before you begin drilling any holes, you’ll want to make sure that the inside of your 55-gallon drum is completely clean.

Next, cut out the top of your drum if there is no removable cover. You’ll then want to strip off its existing paint. You can leave the barrel bare or give it a coat of heat-resistant paint.

After that, go ahead and drill a hole at the bottom of the drum and install the ball valve.

When you’re done with that, you can begin on the shelving. Follow that up with creating and inserting a charcoal basket.

Install your temperature gauge — so you can read the internal temperature — cover the barrel with the lid, and that’s it!
Here is the full guide on how to build your own UDS.

DIY Smokehouse Built from Pallets

A busted fridge or metal drum isn’t the type of ‘look’ you want your DIY smoker to have. Which is perfectly understandable! Then how about constructing a rustic-looking BBQ smoker out of wood pallets? (Not to be confused with wood pellets!)

While you shouldn’t use wood pallets to directly smoke your food. As it is treated with chemicals and will emit toxic fumes — it’s perfectly safe to make a smoker out of this material.

Sure, this has been one of the trickier DIY projects that we’ve tried out! Especially when compared to the fridge cold smoker or the ugly drum smoker.

But it’s so gratifying to turn an ordinary pile of wood pallets into something so much more!

Materials You Will Need

  • Aluminum flashing
  • Aluminum screen
  • Corrugated metal roofing (4 by 3 inches)
  • Deconstructed wooden pallets (30 pieces)
  • Door handle
  • Heavy-duty aluminum foil
  • Hinges (3 pieces)
  • Outdoor screws (1¼ and 2½ inches)

Tools Needed

  • Drill bits (⅛ bit and countersink)
  • Drill gun
  • Measuring tape
  • Reciprocating saw
  • Stanley knife
  • Staple Gun
  • Table saw
  • Tin snips

Basic Skills Needed

You will need to know how to use a drill, reciprocating saw, staple gun, and table saw.

Guide to Building It

You’ll first need to cut the pallets into the desired sizes. Next, set up the foundation for your frame. During this process, you’ll want to keep in mind that there should be a door and an angled roof.

Once you’ve installed all of the panels, then you’ll move on to inserting all of the racks inside. Before the BBQ smoker’s complete, you’ll need to line the smoke chamber with heavy-duty aluminum foil.

Then cut out vent holes on the side. The finishing touch will include attaching a tin roof on top. If you’re looking to smoke large amounts of meat, this is the DIY smoker for you.

DIY Smoker on a Budget

If you’re really on a budget, or if you want to make a makeshift BBQ smoker for camping trips, then we’ve got you covered.

While our other suggested guides are cheap, you might not want to spend $100 on materials. Or you might not have tools like an angle grinder or a welding torch.

Don’t worry because this DIY BBQ smoker is an ingenious idea that only requires a handful of items to make.

Materials You Will Need

  • Aluminum foil
  • Aluminum trays (2)
  • Charcoal or cedar wood
  • Cooling rack

Tools Needed

  • Stanley knife

Basic Skills Needed

As long as you know how to safely use a normal Stanley knife, you can definitely give this DIY a go!

Guide to Building It

Take one of the aluminum trays and cut out two flaps on the side of it. Place in the sizeable cooking rack inside and then poke through the metal skewers on the other side of that tray.

Next, you’ll want to fold up a piece of aluminum foil to use as a divider between the skewers and the cooling rack.

Finally, you can move onto the other aluminum tray. Cut a flap into the bottom of the tray and then use it to cover your first tray. Then all you have to do is place it on a direct heat source, or have some sort of heating element beneath it, and voilà! That’s it!
