How To Build A DIY Barbecue

If you are passionate about DIY and also enjoy welding, here are some useful tips on how to make a DIY iron barbecue, to be used in the garden or on the terrace.

The barbecue is the derivation of an ancient method of cooking food used by the populations of Central America, spread rapidly to the rest of the world by the Spaniards, who introduced it both in Europe and in North America.

Leaving aside the historical curiosities, this tool is appreciated by everyone because it is possible to use it to cook any type of food, including vegetables, and also to smoke; besides the culinary advantages, moreover, the barbecue also promotes socialization, just think of summer barbecues in the company of friends, which is why it is an extremely widespread object and marketed in numerous forms and variations.

On the market, in fact, you can find a great variety of models, from the cheapest to the most expensive; some are small and portable, while others can be considered real building works, such as DIY brick barbecue kits for example. In our article we will illustrate precisely how to build a DIY iron barbecue, which you can keep in the garden or on a terrace, in order to have fun cooking good food on the grill.

Given the material suggested for the realization of this DIY barbecue , however, the project is aimed above all at those who have a minimum of experience in the use of welding equipment ; the iron structure, in fact, will be much more solid and durable if expertly assembled.

While being able to use a normal electrode welder, moreover, to obtain better results it is advisable to use a wire welder ; in fact, TIG welds are known for the extreme cleanliness and regularity of the seams, therefore they are able to ensure greater resistance over time and a much higher aesthetic result than that of MMA welds.

How to make a barbecue: design and materials

When we talk about homemade barbecues , we generally think above all of pre-built kits made of masonry; the use of iron, however, can prove to be a much cheaper and easier choice, especially for those who have a minimum of experience with the welding machine.

All you need to get, to build a barbecue , is the raw material. The project is simple and involves the creation of a structure with a rectangular base, with four iron sections that support the cooking surface and a couple of intermediate shelves; based on this elementary scheme, therefore, first of all proceed with drawing a preliminary sketch with the measures that seem most suitable for your needs.

For this type of barbecue you will need to obtain iron profiles with a rectangular section of 20 × 40, 10 × 10, 20 × 20, 30 × 30, 40 × 40 and 50 × 50 mm, the length of the profiles must be chosen keeping in mind the dimensions you indicated on your project.

Apart from the profiles, you will also need 6 mm thick sheet metal, from 20 to 30 refractory tiles, depending on the size of the barbecue, and 5 kilos of refractory mortar which, together with the tiles, you will use to make the hob where put coal or firewood.

To further enrich your DIY iron barbecue , you will also need to get some wooden slats, four 100 mm diameter Teflon swivel wheels, two of which are equipped with brakes, an adequate quantity of wood screws, a can of paint. of anti-rust undercoat, one of micaceous varnish for finishing, a can of impregnating agent for wood and one of transparent finishing varnish.

How to build a barbecue: practical implementation

Once you have obtained all the necessary material, first of all start by cutting the iron profiles to size using a miter saw or a metal saw, bearing in mind that those intended for frame assembly must be cut at a 45 ° angle; after cutting the profiles you will have to proceed with the assembly with the welding machine, starting with the main support structure for the metal sheet that will hold the refractory tiles.

Also cut and weld the profiles that make up the rest of the frame: that is, the legs and the supporting side members for the lower shelves; the 10 × 10 mm profiles can be cut to size to obtain the support surfaces that will be fixed laterally with respect to the central sheet with the refractory tiles.

Once the metal structure has been assembled, it must be treated with a primer coat of anti-rust protection paint and then, after it has dried perfectly, apply one or two coats of micaceous paint to obtain an antique finish. The wooden slats will need to be cut to the right size to create the support shelves on the lower frame side members and side extensions. The pieces obtained can be fixed with wood screws; before doing so, however, it will be better to paint them with the primer and, as soon as it dries completely, with the transparent finishing varnish.

The hob

We mentioned earlier that tiles and refractory mortar are also needed to make the hob; if you want you can do without it, however, and simply leave the metal sheet on which you can arrange a support grid for wood or coal.

In any case, the use of tiles is preferable, even if it increases costs and production times, both because it ensures greater durability and better functionality, as the refractory tiles diffuse heat more uniformly, and because in this way the wood or coal will not burn in contact with the painted sheet.

Furthermore, during the construction phase of the hob, do not forget to weld pieces of sheet metal at least 5 centimeters high along the side edges and on the front one, in order to create a cornice that prevents the ash from falling to the ground, while at the rear edge you can weld a piece of sheet metal 25 centimeters high, to be used as a shoulder where you can possibly fix a second grid.
