How to build a cheap charcoal grill?

Building your own charcoal grill can be a fun and rewarding project. Not only can you save money compared to buying a pre-made grill, but you also get the satisfaction of creating something with your own two hands. In this article, we will walk through the full process of constructing a simple yet effective charcoal grill using inexpensive materials.

Benefits of a Homemade Charcoal Grill

Here are some of the main advantages of building your own charcoal grill:

  • Cost savings – Pre-made charcoal grills can range from $100 on the low end to over $1000 for high-end models. But with some basic construction skills and $50 or less in materials, you can make your own grill that cooks just as well.
  • Customization – By choosing the design and dimensions, you can create the perfect grill for your needs. Make it larger to fit more food or smaller for tailgating.
  • Quality materials – You control the quality of the steel or other materials used in your homemade grill.
  • Learn new skills – Building something with your hands is rewarding and helps develop new construction and engineering skills.
  • DIY satisfaction – It’s fulfilling to make something yourself instead of just buying it.

As long as you have access to some basic tools and a hardware store, the ability to construct your own high-quality charcoal grill is within reach.

Design Considerations

Before starting your project, think through a few key design factors:

Size

Consider how large your grill needs to be based on how much food you expect to cook at once. Standard kettle grills are around 22 inches in diameter but you can make your grill as big or small as desired. Just allow around 200 square inches of cooking surface per person.

Portability

If you want a grill you can easily move in and out of storage or transport to the park, mount it on a cart with wheels. But for a permanent backyard grill, a heavier stationary design is fine.

Materials

Common options for the grill body include aluminum, stainless steel, concrete, clay bricks, or ceramic tiles. The base can be made from cinder blocks, metal frames, or other sturdy materials. Stainless steel grates are best for even heating and longevity.

Lid

You can fashion a lid from various metals or you could skip the lid altogether and make an open brazier-style grill. Having a lid helps contain heat and smoke flavor.

Accessories

Consider attachments like side tables, storage shelving, thermometers, adjustable grates, or rotisseries. Get creative with features that suit your grilling needs!

Step-by-Step Instructions

Once you’ve settled on a design, gather your materials and tools. Here are the basic steps to follow:

Materials Needed

  • Large metal drum or sheet metal for grill body
  • Steel grates
  • Welding rods and welding/cutting torch if metalworking
  • Concrete, bricks, or mortar if using masonry
  • Nuts, bolts, metal framing for support structure
  • High-temperature paint or finishes

Tools Needed

  • Safety gear – gloves, welding mask, ear protection, etc.
  • Hammer, screwdriver, wrenches
  • Saw to cut metal or masonry
  • Drill with assorted bits
  • Pliers, clamps, square
  • Sandpaper, wire brush

Step 1 – Construct Frame

Start by welding, bolting, or otherwise assembling a metal frame base for your grill. This frame provides structural stability and a mount point for the grill body. Use thick steel bars or square tubing cut and joined into a rectangle or other shape at least 6 inches high.

If using masonry like concrete blocks for the base, lay out the solid foundation.

Step 2 – Add Grill Body

For a metal grill, cut a large steel drum to size or shape sheet metal into a cylinder. Affix this grill body to the top of the frame using welding, bolts, brackets, etc.

Alternatively, build the outer structure using heat-resistant bricks, concrete, clay, or ceramic laid into the frame.

Step 3 – Install Cooking Grate

Cut the steel grate pieces to lay flat within the grill body, leaving around 2 inches of clearance below. Weld, bolt, or otherwise fasten the grates into the body. You can also drill holes to allow the grates to be height adjustable.

Step 4 – Add Lid

Bend and cut a piece of sheet metal into a semicircular shape to create a domed lid. Hinge it to the grill body with metal brackets. Or for a simpler open grill, skip the lid.

Step 5 – Attach Accessories

Here are some optional accessories to trick out your DIY grill:

  • Side tables – Weld on metal brackets to hold wood or metal countertop surfaces
  • Shelving – Use angle irons to hold metal shelves for storing tools and supplies
  • Thermometer – Mount a bbq thermometer to monitor internal temp
  • Grill brush hanger – Screw in a attachment to hold your grill brush
  • Casters – Bolt on wheels for a portable grill

Use your creativity to add useful features to suit your cooking and patio space.

Step 6 – Finish Construction

Once assembled, apply high-heat paint or powder coating to protect the metals from rust and oxidation. For masonry grills, seal the concrete and masonry as needed.

Let any paints or sealants fully cure before lighting your first fire.

Grilling Safety Tips

Here are some important safety precautions to follow when grilling:

  • Grill outdoors in a well-ventilated area away from buildings, trees and shrubs.
  • Keep a fire extinguisher or garden hose nearby.
  • Don’t wear loose clothing that could catch fire.
  • Use long-handled grilling tools and flame-resistant mitts.
  • Clean the grill regularly to remove grease and debris.
  • Don’t leave a hot grill unattended.
  • Dispose of coals and ashes properly in a metal container once completely cooled.

Following basic grilling safety will help prevent accidents and injuries.

Maintenance Tips

Your homemade charcoal grill can provide years of service with proper care and maintenance:

Weather protection

Store the grill in a shed or cover it when not in use to protect from rain and snow. The frame base can rust and the grates will show corrosion if left exposed to the elements.

Regular cleaning

After each grilling session, thoroughly brush the grates clean once the grill has cooled. Periodically give all surfaces a deep cleaning using a wire brush and grill cleaner solution.

Inspect hardware

Check nuts and bolts twice a year and tighten down any that have loosened over time due to heating and cooling cycles.

Touch up paint

Spot paint any scratches or flaking metal surfaces to prevent rust damage.

Replace parts as needed

If grates get excessively worn or other components show fatigue, replace them to keep the grill in safe working condition.

Conclusion

Building your own charcoal grill from scratch is an immensely rewarding do-it-yourself project. By following the steps outlined here and using your creative flair, you can make a high-quality cooking grill customized to your space and needs for much less than a store-bought model. Just be sure to make safety a top priority during construction and anytime you light it up for grilling with family and friends. Any DIY-er with basic metalworking or masonry skills can construct their own charcoal grill to enjoy for years of summer bbq’s to come.
