A car wheel, which many car owners consider useless junk after another tire change or an accident, can find a second life in the form of a stylish and functional barbecue. Creation disc grill - this is not just a way to recycle scrap metal, but also an excellent opportunity to show engineering ingenuity, resulting in a unique product that will become the center of attention at any country party. Unlike standard store-bought models, homemade versions often have thicker walls, hold heat better and look much more brutal.
The remodeling process requires a minimal set of tools, but involves working with metal, fire and electricity, so compliance with safety precautions comes to the fore here. You don't need to be a professional welder to put together a decent structure, but basic welding skills Bulgarian and welding machine will be extremely useful. In this article we will look in detail at all the stages of turning an old wheel into a work of art for frying meat.
The main advantage of this solution lies in the geometry of the product: the central part of the disk is ideal for installing a spit, and the sides create a natural wind shield for the coals. In addition, the steel used for the wheels has high heat resistance and does not deform from frequent temperature changes as quickly as the thin metal of cheap barbecues. Let's look at where to start and what nuances to consider.
Selecting a suitable disk and preparing materials
The first step in creating a quality grill is choosing the right starting material. Not just any car wheel is suitable for this purpose: stamped steel models (called “stamped”) are best suited due to their design and the thickness of the metal. Light alloy wheels made of aluminum or magnesium use absolutely not recommended, as they may melt at high temperatures or release harmful substances when heated.
The optimal choice would be a wheel from a passenger car with a diameter of R13–R16. Discs that are too small from Oka or Tavria will have a small area for frying, and huge “rollers” from SUVs can be excessively heavy and inconvenient to carry. It is important to inspect the workpiece for deep corrosion or cracks, especially in the area of the welded central cup, since this is the part that will bear the main load.
⚠️ Attention: Never use discs with strong swelling of paint or traces of unknown chemicals inside for grilling, as when heated they can emit toxic smoke that will saturate the food.
In addition to the disc itself, you will need to prepare a number of tools and additional materials for assembly. Make sure in advance that you have access to electricity to operate the power tool and a place where you can weld safely without the risk of fire.
- 🛠️ Angle grinder (grinder) with a set of cutting and cleaning wheels for metal.
- 🔥 Welding machine (inverter or semi-automatic) and consumables (electrodes, wire).
- 📏 Tape measure, metal marker and drawing square for precise marking of cutting lines.
- 🎨 Heat-resistant paint (coking) for final surface treatment.
Careful preparation of the workplace will save you time during the work process. Place all the tools in an accessible area so you don’t have to search for the necessary equipment in the middle of work. It is also worth preparing personal protective equipment: goggles, gloves and a respirator, as there will be a lot of dust and sparks.
Technology for cutting and forming a barbecue bowl
The most critical stage of creation barbecue from a disk - this is the correct cutting of metal. It will be almost impossible to correct mistakes here, so measure seven times before turning on the angle grinder. The main task is to cut off the upper part of the disk (welding bowl) so that there remains a flat, deep container for coals. There are two main ways to perform this operation.
The first method involves cutting the disk in half along the equator. In this case, you get two symmetrical bowls, which allows you to make a grill with a lid or even two separate small grills. The second, more popular method is to cut off only the top edge at the level of the beginning of the rolling. This option is preferable as it maintains the maximum height of the sides, which is important for retaining heat.
☑️ Disc cutting plan
When making a cut, try to move the tool smoothly, without strong pressure, so that the disc does not overheat and deform. If you are working alone, it is better to secure the wheel to a workbench or press it to the ground with your foot (in thick shoes!), but it is safer to use clamps. After finishing cutting, be sure to run a sanding wheel over all edges to remove any burrs that could cause injury.
Next, you need to remove the central part of the disk, leaving only the outer edge. To do this, radial cuts are made from the center to the edges, after which the “nickels” are knocked out with a hammer. If you plan to make a grill with airflow, then in the lower part of the bowl, in the place of the former central hole, you can leave the standard holes or drill a new row of holes with a diameter of 10–12 mm.
Manufacturing of the lid, legs and ventilation system
The lid is the element that turns a simple roaster into a full-fledged one grill, allowing you to cook meat by smoking or simmering. To create it, you can use the cut off upper part of the disk if you sawed it in half, or cut a separate circle from sheet metal 2-3 mm thick. It is necessary to weld a handle to the lid, which must be insulated with a wooden or textolite overlay so as not to get burned.
The ventilation system is critical to the combustion of coals. If the standard holes in the bottom are not enough, they need to be added. However, it is important not to overdo it: too large holes will lead to rapid burning of the coals and ash loss, and too small ones will not provide the necessary draft. The optimal solution is an adjustable damper, which can be made from a metal plate.
| Design element | Recommended Material | Function | Installation features |
|---|---|---|---|
| Grill bowl | Steel wheel R13–R15 | Coal container | Requires edge cleaning |
| Legs | Profile pipe 20x20 mm | Stability and height | Welded at an angle for stability |
| Pen | Metal rod + wood | Lid control | Mounted with bolts or welding |
| Grate bars | Reinforcement d8–10 mm | Coal support | Cooked crosswise or parallel |
The legs for the barbecue can be made stationary or removable. The stationary option is more reliable: four sections of profile pipe or angle are welded to the sides of the disk at a slight outward angle for better stability. Removable legs are more convenient for transportation; they can be screwed into welded nuts or inserted into sleeve pipes, secured with bolts.
Inside the bowl, just above the bottom, it is recommended to weld small stops or a shelf for installing removable grates. This will raise the coals above the bottom, providing better air flow and protecting the bottom from rapid burning. Sections of reinforcement laid parallel or crosswise are ideal as grate bars.
Welding work and structure assembly
Assembling all elements into a single structure requires care. Before tightly welding the legs or hinges for the lid, assemble the grill “on tacks” and check its stability on a flat surface. A wobbly grill is a hazard as knocked over coals can cause fires or burns.
When welding the hinges for the lid, it is important to maintain alignment. The hinges must be welded so that the lid opens to an angle of at least 90 degrees and, in the open position, does not fall back under its own weight. A simple chain or metal stop can be used to secure the lid in the open position.
Secrets of high-quality welding of thin metal
When welding thin-walled disk elements, use minimal current and short seams, pausing to allow the metal to cool. This will help avoid burning holes and warping the structure. If the metal does burn through, place a copper plate under the welding site - it will remove excess heat.
If you plan to install a spit for cooking chicken or large pieces of meat, you need to provide supports for it on the sides of the grill. These can be U-shaped cutouts in the sides or welded semicircular brackets. The spit itself is made of a square rod (to prevent the meat from spinning) with a handle at one end.
The final step in mechanical assembly is to clean all welds. This not only improves the appearance of the product, but also prevents the accumulation of moisture and dirt in the microcracks of the slag, which extends the service life of the barbecue. After cleaning, the surface should be smooth and ready for painting.
Anti-corrosion treatment and decoration
Metal, especially after welding and cutting, is subject to rapid corrosion. To your grill made from a car wheel served for many years and did not rust after the first rain, it must be properly treated. Ordinary paints are not suitable for this - they will instantly burn and begin to release toxic substances.
The ideal solution is heat-resistant enamel that can withstand temperatures up to 600–800°C. Such paints are often used to paint mufflers, engines or furnaces. Before painting, the surface must be degreased (for example, with acetone or white spirit) and primed with heat-resistant primer for better adhesion.
- 🎨 Apply paint in 2-3 thin layers, waiting for each previous one to dry completely.
- 🔥 Carry out the first “burning” of the finished product without food, on high heat, so that the remaining solvents burn out.
- 🧹 Regularly clean the grill from ash after use, as ash absorbs moisture and accelerates corrosion.
The appearance of the barbecue can be anything: from strict black to complex artistic paintings. Some craftsmen weld forged elements, decorative rivets to the sides, or even turn the grill into the figure of an animal (boar, pig), using additional metal parts. Fantasy is not limited here.
⚠️ Attention: Do not use ordinary nitro enamels or oil paints to paint the inside of the grill - at the first heating they will create an unbearable stench and ruin the taste of the meat forever.
Operating rules and safety precautions
Operating a homemade barbecue requires compliance with certain rules. Although the design seems simple, open flames and hot metal pose risks. Always place the grill on a non-flammable surface: concrete, tiles or soil cleared of dry grass.
Do not leave a burning grill unattended, especially if there are children or pets nearby. After use, allow the coals to burn completely and cool. You cannot pour water on a hot disk - a sharp temperature change can lead to deformation of the metal or even the appearance of cracks in the welds.
To quickly ignite, use special liquids or dry fuel, but never pour gasoline or diesel fuel directly onto the coals - this can lead to a flash of flame and burns.
Check the condition of the legs and fastenings regularly. Frequent heating and cooling causes the metal to become “tired” and welds may weaken. If you notice any looseness, immediately weld the joint or reinforce it with additional gussets. Safety comes first.
Compliance with painting technology and regular cleaning of ash are the main factors in the durability of your homemade grill.
By following these simple guidelines, you will not only have a functional cooking tool, but also a piece of pride that will last you for many seasons. A disc grill is proof that you can create truly valuable and useful things with your own hands from old things.
Frequently asked questions (FAQ)
Is it possible to make a grill from a cast (alloy) wheel?
It is highly undesirable to do this. Aluminum alloys have a low melting point and can lose strength or melt when exposed to extreme heat. In addition, the combustion of some alloy components may release harmful oxides. It is better to use only stamped steel wheels.
Do I need to make holes in the bottom of the grill?
Yes, the holes are necessary to create draft, without which the coals will burn poorly and produce a lot of smoke. However, do not make them too large, otherwise the ash will spill out and the heat will go down. The optimal hole diameter is 10–15 mm.
What is the best way to paint the inside of the grill?
It is better not to paint the inside at all, but simply calcinate it before the first use so that the factory grease burns out and a layer of soot is formed that protects against rust. If painting is necessary, use only food-grade heat-resistant enamels certified for contact with high temperatures.
Which disk is better to choose: from a car or from a truck?
For country use, a disc from a passenger car (R13–R15) is optimal. Weight discs are too heavy, take up a lot of space and require huge amounts of charcoal to heat, which is not economically feasible for cooking for a family.
