Building A Fire Pit For Your 15-Gallon Cooking Pot

how to build firepit around 15 gallon cooking pot

Building a fire pit for a 15-gallon cooking pot can be a simple and inexpensive project. While specific instructions may vary depending on the desired design and available materials, one common method involves using a steel drum. First, obtain a steel drum, preferably with a lid and a strap, which can often be sourced from salvage yards or online marketplaces. Ensure the drum is free from unknown chemicals. Next, cut the drum in half horizontally using a metal-cutting circular saw or an angle grinder. One half will serve as the main body, while the other will be cut vertically and resized to fit inside the first half, creating a double-wall construction. Add a bottom to the structure and create a cap that bridges the inner and outer walls. Finally, customize the fire pit to your needs, such as adding a metal grate or a hanging bar for your 15-gallon pot, ensuring proper support and stability. Remember to prioritize safety measures and always exercise caution when working with fire.

Use a steel 55-gallon drum

To build a fire pit around a 15-gallon cooking pot, one option is to use a 55-gallon steel drum as the base structure. Here's a step-by-step guide on how to do it:

Source a suitable 55-gallon steel drum

You can find these drums at local salvage yards or online marketplaces like Facebook Marketplace or Craigslist. It is recommended to choose a drum that previously contained food-grade or non-toxic substances. Stainless steel drums offer better corrosion resistance than carbon steel drums, which can rust over time. Ensure the drum has a lid and a strap to lock it in place, as well as a spare lid.

Prepare the drum for cutting and welding

Before cutting or welding, ensure that any plugs or covers are removed to prevent a dangerous build-up of pressure. Use a marking crayon or chalk box to establish a straight line for cutting. You can also elevate the drum from the ground or deck surface to provide a stable foundation during the cutting process.

Cut the drum to create the fire pit structure

Cut the drum roughly in half horizontally using a metal-cutting circular saw or an angle grinder with a cut-off wheel. Then, take one of the halves and slit it vertically down the side. Squeeze this piece to a smaller diameter so that it fits inside the other half, creating a double-wall construction.

Prepare the metal surface for finishing

Use a twisted wire wheel on an angle grinder to remove paint and prepare the metal for welding. Be cautious when using a flap disc as it can remove some metal. If there is any paint or coating on the inside of the drum, it is recommended to burn it off by lighting a small fire inside before using your fire pit for cooking.

Weld the structure and add ventilation

Weld the two halves together, creating a cap that bridges the tops of the inner and outer walls. You can use a MIG wire feed welder or a flux core wire feed welder for this step. Finally, cut holes around the base, the bottom inside, and the top edge inside to provide ventilation and allow your fire to breathe.

With these steps, you can create a functional and unique fire pit around a 15-gallon cooking pot using a 55-gallon steel drum.

Cut the drum in half horizontally

To build a fire pit around a 15-gallon cooking pot, you'll first need to source a steel drum of a similar capacity. You can find these at salvage yards, Facebook Marketplace, or Craigslist. Once you have your drum, you can begin the process of cutting it in half horizontally.

Before you start cutting, it's important to take the necessary safety precautions. Wear protective gear, including gloves, eye protection, and a respirator. Ensure you are in a well-ventilated area or are using a respirator to avoid inhaling harmful dust or fumes.

Now, onto the cutting process:

  • Measure the diameter of the drum at both the top and bottom.
  • Using a felt-tip pen, mark the radius and trace a horizontal line across the diameter of the drum.
  • Tie the drum firmly to ensure it retains its shape during cutting.
  • Sprinkle some water on the drum to lessen dust formation during cutting.
  • Choose your cutting tool. You can use a metal-cutting circular saw, an angle grinder with a cut-off wheel, or a side grinder with a cutoff wheel. A special-purpose blade on a skilsaw or a plasma cutter are also options but may be more costly or dangerous.
  • Start cutting at the bottom part of the drum, working your way up to the top.

Once you've cut the drum in half, you can continue with the next steps of your fire pit project, such as creating a base and a cap, as well as cutting holes for ventilation. Remember to always prioritize safety when working with power tools and metal cutting.

Create a double-wall construction

To create a double-wall construction for your fire pit, you will need a 55-gallon drum, a tool to cut the drum (such as a metal-cutting circular saw or an angle grinder with a cut-off wheel), and a tool to remove paint and prep the metal for welding (such as a twisted wire wheel on an angle grinder or a flap disc).

First, cut the drum roughly in half horizontally to create the main body of the fire pit. Then, take one of the halves and slit it vertically down the side. Squeeze this piece to a smaller diameter so that it fits inside the other half, creating the inner and outer walls of the double-wall construction.

Next, add a bottom to the fire pit and create a cap that bridges the tops of the inner and outer walls. Finally, cut holes around the base on the outside, in the bottom inside, and around the top edge inside. These holes will allow air to enter the cavity at the bottom of the fire pit and rise through the gap between the two walls as the fire burns.

The specific steps to create a double-wall construction for a fire pit around a 15-gallon cooking pot may vary, but the general process outlined above should provide a good starting point.

Make a permanent base for the pot

To make a permanent base for a 15-gallon cooking pot, you will need to create a sturdy structure that can bear the weight of the pot and its contents. Here is a step-by-step guide to help you achieve this:

Planning and Materials

Begin by sourcing a steel or iron pipe with a diameter slightly larger than 15 gallons. This pipe will serve as the base structure. You will also need a U-shaped bar made of black iron or steel that fits snugly inside the pipe. This bar will support the cooking pot. Additionally, you will need threaded metal covers to protect the base pipe when not in use.

Installation

Dig a hole a few feet deep to accommodate the base pipe. Ensure the hole is straight and stable, as this will provide structural integrity for the entire setup. Place the large pipe firmly inside the hole, securing it with concrete or another suitable material to ensure it remains firmly in place.

Final Touches

Create a cap or cover for the base pipe to prevent debris from falling inside when not in use. You can use a threaded metal cover, as mentioned earlier, or create a custom cap that fits the pipe's diameter. Ensure the cap is secure and weather-resistant to protect the interior of the pipe from the elements.

Using the Setup

When you're ready to cook, simply remove the cap and slide the U-shaped bar into the base pipe. Place your 15-gallon cooking pot on the bar, and you're ready to start cooking. When you're finished, allow everything to cool down, then slide out the U-shaped bar, and cover the base pipe until your next cooking session.

This setup provides a safe and permanent base for your 15-gallon cooking pot, ensuring stability and durability for your outdoor cooking endeavours.

Use a metal grate for cooking

Using a metal grate for cooking over your fire pit is a simple and inexpensive way to create a cooking setup. You can either buy a metal grate or make one yourself.

If you want to buy a metal grate, you can find good-quality options at RV centres. You can also check out online retailers like Amazon, which offer cast iron grates for gas grills that can be placed across the top of your fire pit. Another option is to purchase a fire pit with a cooking grate, which you can find on Amazon or at stores like ALDI.

If you're handy and want to build your own metal grate, you can use angle iron and expanded metal, or even take the grate out of an old junked stove or gas grill. You can adapt these grates to be elevated above the fire pit and swing in and out of the heat. For stability, you can create a permanent base by sinking a metal post into the ground to support the grate.

With a metal grate in place, you'll be able to cook a variety of foods over your fire pit, from steaks to soups and everything in between!
