Metal grill: instructions for making
Brazier, as you know, is called a special device with which anyone can cook a kebab or barbecue on the coals. You can purchase the finished structure in the store or make it yourself.
Externally, these devices are a metal box, welded or assembled from sheet blanks with a thickness of about 1.5–3.0 mm. Similar products have a number of indisputable advantages:
- ease of manufacture;
- easy handling;
- increased fire safety;
- relatively low cost.
Materials and tools
The following tools and materials are required:
- iron sheet of a given size;
- set of mounting bolts;
- welding machine of any type;
- electric drill with a set of drills;
- Bulgarian with a set of discs for metal;
- yardstick.
Before starting work, you should decide what size the grill will have. For a small family, a brazier with a size of 50 × 30 cm is quite enough, while for a large friendly company its size should be chosen individually (by the number of permanently present team members). When choosing dimensions, such parameter as the luggage capacity of your personal car should be taken into account.
For the manufacture of the brazier, you should use a steel sheet with a thickness of at least 1 mm, since the thicker the iron is, the longer the finished fixture will last. The legs for the brazier can be made of the same metal, forming a rigid structure from the strips (in the form of alternating corners).
Assembly
In that case, if you have a welding machine at your disposal, then you can make a brazier from separate blanks very simply. In the course of assembling the structure, pre-marked and cut sheet blanks are molded so that stripes are formed at their edges, which are located at an angle of 90 degrees to the base sheet. Then they are welded along the butt line along the entire length of the blanks, after which a bottom is welded to the resulting box, in which holes are made in advance for dumping the ash into a separate section.
The brazier legs are recommended to be bolted, which will allow you to easily dismantle them (for example, if transportation is necessary).
In the absence of a welding unit, the frame is manufactured using bolted joints. At the same time, in advance prepared blanks, it will be necessary to drill at least three holes of the appropriate size - along the edges and in the central part of the sheets that are joined together.
The strips are applied with curved edges to the bottom of the box and bolted through the prepared holes. The safety margin of such a structure is quite enough to withstand the load from the fuel placed in the brazier.
At the end of the frame assembly, holes of 2-3 cm in size (with a step of about 4-5 cm) are drilled in its side walls at a height of about 3 cm from the bottom. These holes will serve to obtain an air draft or to “inflate” the coals.
Some tips from experienced craftsmen
Check out a number of recommendations:
- Before using new sheets of iron, it is advisable to pre-ignite them with a blowtorch to remove a layer of factory protective coating.
- It is best to make the supports for the barbecue removable, which makes it easy to transport it to the picnic area. These legs can be easily made from the corners, which are fixed at the corners of the structure by means of bolts.
- The height of the firebox is selected from the calculation so that the meat does not burn when it is cooked in the heat. It has been established experimentally that this value should be in the range of 20-25 cm.
- Blowing in such devices is usually not provided, because the coals in them and so burn through quickly enough.
- Instead of a blower, you can make one of the end walls of the frame removable, which allows you to easily clean the ash collection section.
In the lower part of the construction you can make a special shelf on which it will be convenient to store fuel for barbecue (wood, wood chips or coal).
