Design rocket furnace is no secret to experienced craftsman. But today we will see an unusual rocket stove made from an oxygen cylinder.
The rocket stove, thanks to its parameters, has gained popularity all over the world. Unpretentiousness to fuel, good heat dissipation, ease of manufacture are the main advantages of such a furnace. By the way, the rocket stove is also made in residential premises for heating and cooking, and not just as a “camping” or “outdoor” option.
DIY rocket stove from an oxygen cylinder
- Step one: cutting the balloon
- Step two: loading chamber
- Step Three: Loading Hole
- Step four: ash pan
- Step Five: Vortex Flow
- Step six: welding work
- Step seven: thermal insulation
- Step eight: gas afterburning system
- Step Nine: Cover
- Step ten: support
There are several options for building such a furnace. The master combined two such versions of photos 1 and 2, and made his photo 3.
For production, the homemade master used the following
Tools and materials:
- Oxygen balloon;
- Cardboard;
- Marker;
- Insulating tape;
- Magnetic square;
- Welding machine;
- Profile pipe;
- Band-saw for metal;
- Channel;
- Roulette;
- Wire brush;
- Hammer;
- Clamp;
- Metal container;
- Pliers;
- Bolt;
- Two bushings;
- Perlite;
Step one: cutting the balloon
For the stove to function properly, its vertical part must be 2.5 times longer than the fuel chamber. Taking this into account, the master marks the cylinder. For an even cut, wrap a piece of cardboard around the balloon, align the edge and outline it with a marker. When marking volumetric parts in this way, you can be sure that the cut location will be level.
Step two: loading chamber
Now you need to properly cut off the edge of the loading chamber. The master makes a template from paper. Transfers the template to the workpiece.
Cuts according to markings.
Step Three: Loading Hole
By using magnetic square secures the loading chamber to the workpiece. He traces it along the contour from the inside and outside.
Checks the fit and adjusts if necessary.
Step four: ash pan
The ash pan provides access to the combustion chamber and can also be used to control draft. The master made the ash pan from profile pipe 100*100 mm. Cut it to the required size.
I adjusted it to the radius of the pipe.
I cut a hole in the pipe.
Step Five: Vortex Flow
To ensure greater draft, the master makes fresh ventilation. The pipe will draw in air and, passing through the curved pipe, it will increase the draft.
Trims channel flanges.
Bends the edge of the workpiece around the pipe.
Step six: welding work
All parts are prepared and welding can begin.
Welds the loading chamber.
Now you need to measure where to cut the hole for supply ventilation. The craftsman places the workpiece on the ash pan and outlines the location of the curved part.
He welds the workpiece and scalds the ash pan.
Step seven: thermal insulation
The master uses a barrel to insulate the upper part of the riser. Cuts a hole in it. Makes "petals".
Holidays outside the city, be it a dacha or a picturesque clearing in the forest or near a pond, very often involve cooking barbecue. Of course, for this you can get by with a few bricks and a couple of metal crossbars, but the real pleasure of cooking meat on skewers can only be obtained next to a convenient and practical barbecue. A good design can be made from thick sheet metal. If you don’t find one on your farm, then you shouldn’t rush to the construction market. You can make an excellent device for cooking meat with your own hands from a regular gas cylinder.
Features of a barbecue made on the basis of a container for liquefied gas
Cylinder for domestic gas is an excellent basis for many homemade designs. Good quality metal, an almost ready-made shape and several standard sizes make it possible to obtain a potbelly stove, indirect heating boiler, autoclave and other household equipment with minimal labor costs. Thick walls of the container from under liquefied gas are able to withstand high temperatures, so it is ideally suited for making a smokehouse, barbecue or grill. Other advantages of the design are also known:
A barbecue built from a household gas tank has virtually no disadvantages. Some consider the large dimensions to be a disadvantage, but what’s stopping them from taking a smaller cylinder, for example, 27 liters? The only negative aspects include the semicircular shape of the bottom, which is not very convenient when lighting firewood. On the other hand, with this configuration the coals will be closer to the edges of the skewers. Due to this, the outer pieces of meat will be better baked, which often remain raw when cooked on a traditional rectangular roasting pan. Experts believe that the spherical walls of the grill are not entirely suitable for preparing kebabs, since they interfere with the processes that help “unfold” the rich aroma of baked meat. In the future, we will touch on this issue, revealing the secret of how to avoid the disadvantages associated with the round shape of the bottom.
Preparatory activities
Before you pick up a welding machine, you need to select a gas cylinder and prepare it for work, draw up a rough sketch of the future barbecue and stock up necessary tool and materials.
What kind of cylinder can I use?
Any gas cylinders are suitable for making a barbecue cylindrical. The best option is quite capacious and the most common 50-liter container for household propane-butane. If you want to get more mobile and lightweight design, which can be transported in the trunk passenger car, you can take a standard 27 liter cylinder. It should be taken into account that the width of the working space portable barbecue may not be enough due to the spherical shape of the sidewalls.
Gas cylinders are made of high-alloy low-carbon steels 30ХМА, 45, 34CrMo4, 30ХГСА. High content alloys and a decrease in the number of alloys in the metal makes the alloy more durable and improves anti-corrosion properties.
An ideal option for a stationary barbecue would be a 50–80 liter car gas cylinder. It has an increased diameter, so it will be much more convenient to light firewood. In addition, such a vessel has increased capacity. Its width makes it possible to use the entire length of a standard skewer, and this will allow you to cook dinner for a large company. The only caveat is that finding an unnecessary car gas tank will not be easy, and buying a new one will not be financially feasible.
Gas cylinders are made of high-quality alloy steel with a thickness of 3 millimeters or more, therefore, even if the container long time stood in the open air, it will most likely be usable. If the vessel is heavily rusted, then you should not waste time on it - finding a workpiece in good condition will not be difficult.
How to protect yourself from explosions
Even if the valve of the container you are using is completely unscrewed and gas does not come out of it, do not rush to take up the grinder. Despite the fact that the pressure inside the cylinder is equal to atmospheric pressure, most likely there are unsafe substances left in it - propane-butane and condensate. The latter is drained by turning the vessel upside down, and in order to completely remove the explosive contents, the container is filled to the top with water and left for several hours. Only after this requirement has been met and the liquid has been drained can you begin cutting and welding the metal.
Schemes and drawings
A barbecue made from a gas cylinder is so simple construction, which does not require careful design. However, on preparatory stage It is recommended to draw up a small drawing or sketch of the future structure indicating the dimensions of all its elements. This will make it possible to determine how much and what kind of rolled metal will be required, and will also allow you to correctly plan individual processes. Perhaps the drawings and diagrams presented in our gallery will help you in working on the barbecue.

Materials and tools needed for work
In addition to the gas cylinder itself, you will need:
- sections of steel pipes and angles;
- metal handles for the grill lid;
- door or furniture hinges;
- a pipe with a diameter of 100 mm with a 90-degree elbow, if you plan to install a chimney;
- grate that you will need for a barbecue;
- bolts with nuts or rivets.
In addition, you should prepare decorative elements, intended for refining the structure, as well as primer, paint and solvent that will be needed for painting it.
If we talk about tools, we are sure that everyone interested in the issue of construction will have them. homemade barbecue:
- welding transformer or inverter;
- Angle grinder - angle grinder (colloquially “grinder”);
- electrodes Ø3–4 mm;
- cutting and cleaning disc for angle grinders;
- electric drill;
- a set of drills for working on metal;
- clamps for fixing metal parts;
- long metal ruler;
- scriber;
- core;
- adjustable and gas wrench;
- set of wrenches.
If after manufacturing the grill will be painted, then additionally prepare a brush attachment for a drill or grinder, as well as brushes or a sprayer with a compressor.
Making a barbecue with your own hands from a 50-liter household gas cylinder
Installation work is best carried out in a well-ventilated area or outdoors. The place where the assembly will be carried out must be fairly level, otherwise it will not be possible to ensure the correct geometry of the structure and the grill will be unstable.
When carrying out plumbing work, it is important not to forget about safety rules and be sure to use protective equipment and special clothing.
Step-by-step instruction
- Unscrew the valve. To do this, use a gas or adjustable wrench. Sometimes shut-off valves It sours so much that there is no way to unscrew it. In this case, the tap can be cut with an angle grinder. Using the same tool, cut off the lower support rim - with it the structure will look unaesthetic.
- Mark the cutting areas. The diameter of the 50-liter propane-butane tank is 960 mm, which allows it to be accurately divided into four parts. It is convenient to take the longitudinal seam as a reference point. Having placed the cylinder on flat surface, from the welding line in both directions, measure a quarter of the diameter - 240 mm and apply horizontal markings that will divide the cylinder in half. An indent of at least 30 mm is made from the line of fastening of the upper and lower parts of the vessel, after which circular lines are drawn. The distance between them is divided into equal intervals of 80–100 mm, on which the skewers will be placed. After this, mark the grill cover. Its length should be less than half the diameter, so 100 mm is measured from one of the longitudinal lines towards the horizontal welding seam. A parallel drawn strip will indicate the location of the cut.
- Having installed a cutting disc on the grinder, cut a line that divides the diameter of the cylinder in half. After this, the slot is marked into equal parts and the hinges are welded. Their number can be from two to four (depending on size). After this, the cover is cut out along the circular marks, as well as a longitudinal line, which is located at a distance of 140 mm from the horizontal seam.
Don't rush to cut out the entire lid at once. Subsequently, this will entail a lot of inconvenience associated with its correct orientation, setting gaps, etc. Doing this without an assistant will be problematic. If you immediately weld the hinges along the first cut line, you will be able to save a lot of time and nerves in the future.
- In order for the top door to be held in the desired position and not break the hinges when tilted, it is necessary to weld stoppers along the cutting line. They can be made from 20–30 mm pieces of steel angle with a shelf width of 40–50 mm. The fixing stops are mounted on both sides - this will prevent the lid from warping.
The distance at which the door will tilt can be changed by unbending the clamps to the required angle. At the same time, choose a position in which you can easily reach the lid handles without bending forward too much, and at the same time will not allow the structure to slam shut spontaneously.
- To prevent the door from falling inward when closing, a stopper must be welded around the perimeter of the circular cutouts. To do this, a strip 30–40 mm wide is cut from sheet steel 1–3 mm thick. It is secured from the inside of the cylinder with an intermittent seam.
Instead of limiters, you can use a length of chain required length, welding it at one end to the grill and the other to the lid.
- Below the hinges, a series of Ø12–14 mm drillings are made for skewers. Previously, these places were marked along the diameter dividing line. On the front wall opposite each hole, slots or triangular cutouts are made on which the skewers will be placed.
- Install handles for opening the lid. For this, factory-made products with linings made of wood or fire-resistant composites are best suited - they will not allow you to get burned. IN as a last resort, the handle can be made by bending a piece of metal rod or fittings into the shape of the letter “P”.
- At the next stage, holes are cut in the bottom of the grill to allow air to enter the combustion zone. To do this, turn the structure upside down, measure 100–120 mm in each direction from the longitudinal seam and draw horizontal lines. Setting aside 100 mm from these marks, strips are obtained in which cuts are made every 50 mm. Instead of slots, you can make drillings. In this case, holes with a diameter of 10–12 mm are made in a checkerboard pattern.
Cutting through the bottom to supply air is impractical for a number of reasons. Firstly, this will weaken the welding seam, which makes the structure more rigid, and secondly, the holes will quickly become clogged with fat deposits mixed with ash and ash, and will cease to perform their functions.
- The hole for the valve must be welded. If the grill is also planned to be used as a smokehouse, then the opening is expanded to the diameter of the chimney. After this, a chimney is welded to the cylinder.
At this point, the main part of the work is considered completed. All that remains is to install the grill on the legs and decorate it interesting decor or simply paint the structure with heat-resistant paint.
Installation of barbecue supports
There are several options for installing the barbecue on legs, which is facilitated by the fairly thick metal of its body. The first and easiest method is to weld four pieces of steel pipe or a corner directly to the body. Of course, the connection points must be carefully verified, and during the work, use a square and building level, otherwise the design will look askew and untidy. Everyone makes the height of the barbecue for themselves, but there is also a standard recommendation - the distance from the ground to the plane where the skewers are laid should be no more than 1 m.
It is worth noting that the method described above cannot add presentability and convenience. If you want to get a stylish, practical structure, then for this you will need to make a frame-type support. To do this, from the profile metal pipe A pair of side posts are made 20x20x2 mm. In its upper part, a semicircular bed is welded from a metal tire, curved to the shape of a cylinder. Both parts of the structure are fastened together with the same metal profile so that a kind of underframe is obtained. The cylinder is placed on the prepared bed and secured by welding. In order to make the barbecue more mobile, metal wheels can be attached to the legs.
Made from a household gas cylinder, the barbecue can be taken with you during forays into nature. To ensure that it does not take up much space in the trunk of a car, the supporting structure is made collapsible. All you need for this is a 40-centimeter piece of pipe with an internal diameter of 18–30 mm and a 3-meter pipe with a diameter of 16–28 mm. The main requirement is that when pairing them, the gap is small, otherwise the grill will be unstable.
By cutting a short piece into four equal parts, couplings are obtained, which are welded to the cylinder at the places where the supports are installed. After this, the grill is installed on the legs and through drilling is performed to fix them inside the couplings. The pins inserted into these holes allow you to easily carry assembled structure- the tubes will not fall out. Additionally, carrying handles can be welded to the sides of the portable barbecue. By the way, during transportation of the structure, all legs, firewood (or packaging of coals) and lighter fluid can be placed inside. Such optimization will save a lot of space in the trunk.

How to bring a design to perfection
The ease of manufacture and other advantages of a BBQ from a cylinder are somewhat overshadowed by the conclusions of barbecue experts that the meat in them is not as tasty as in traditional-type braziers. A thorough study of the problem revealed several points of failure.
- Due to the rounded bottom, the layer of coals in the center and at the edges differs in height. This heterogeneity leads to the fact that firewood located on the periphery burns out much longer than in the middle of the stack - the heat in the center settles much faster.
- The spherical walls emit infrared rays not towards the kebab, but towards the coals, which further enhances the effect described above.
- Unlike a flat-bottomed design, the supply of oxygen to a barbecue made from a round container is uneven.
Eliminating the shortcoming that prevented us from getting the “correct” kebab turned out to be quite simple. Refinement of the barbecue requires the installation of a longitudinal air duct along the entire length of its bottom. To do this, you will need a steel corner measuring 80x80 mm and 900 mm long. Holes with a diameter of 12–15 mm are made in both of its shelves in increments of 50 mm. The air duct is welded into the bottom so that both its edges remain outside. The essence of the improvement is more clear from the presented figure.
How to paint it “cheaply and forever”
A metal structure must be painted for both aesthetic and practical considerations. Unprotected steel will quickly rust, which will not add either beauty or durability to the structure. Any heat-resistant paint intended for car mufflers is best suited for painting a barbecue, but its high price and complex application technology do not allow us to call this option ideal. Silicone-based paints, specially created for painting, have the same disadvantages. metal furnaces, fireplaces, barbecues and grills.
A cheap and practical material is Kuzbass varnish and similar mineral compositions based on bitumen resins.
The coating should be done in 3-4 layers, with complete intermediate drying after each application. Of course, paint inner surface There is no need for a barbecue - a coating of soot, on the contrary, will contribute to obtaining an ideal product.
The disadvantages of this method are long drying times and unpleasant, toxic fumes. In addition, the paint remains fragile for a long time, so it requires careful handling. The first 2-3 firings are best done “idle”. This will eliminate the odor and make the coating more durable and safe. When mineral composition baked, it will be very difficult to damage it. Practice shows that such a composition does not require updating for decades.

Many options for barbecues built on the basis of a gas cylinder allow you to build a practical, functional and original design. It can be placed under a canopy or in a gazebo, installed outdoors or made completely mobile. A properly built grill produces soft and even heat, which makes the kebab soft and juicy. Therefore, all that remains to be wished is good company and bon appetit!
To make a barbecue from a gas cylinder, you first need to understand the device. To cook kebabs, fish or vegetables over an open fire, different devices are used: barbecue, grill, tandoor, etc. Barbecue is in many ways similar to these devices. However, it is more similar to a grill. It’s easier to make a barbecue with your own hands, since it is not equipped with a lid and requires the use of skewers for cooking. A mobile barbecue and grill are made according to very similar schemes. Both designs are equipped with a grille and often have a lid.
A high-quality barbecue and similar devices are quite expensive. If you make a barbecue from a cylinder with your own hands, the cost of construction will be lower. As a result, you will not have to spend a large amount. Other advantages of this solution:
- significant length (about 120 cm), which allows you to cook in one go a large number of products;
- relatively simple installation process;
- a minimum of materials used, since the barbecue is made from a propane cylinder;
- the basis of the structure is heat-resistant metal (3 mm thick wall);
- the presence of a lid protects food and fire from precipitation; in addition, it can be used to regulate the flame.
However, there are also disadvantages. For example, the volume of the cylinder is quite large, which makes it difficult to use in a small yard. Another disadvantage is the significant weight. It is difficult to move such a barbecue. This work is best done together. Propane cylinders are distinguished by their considerable length and wall thickness.
Another disadvantage is the unattractive appearance. It is not recommended to paint the structure, as it is constantly exposed to high temperatures, but if you wish you can choose Decoration Materials with suitable properties. They also note the impossibility of using firewood. The whole point is that a barbecue made from a gas cylinder is not high enough. Considering that the free space is also limited by the grate, it is not possible to put firewood inside.
Tools and materials
To get an idea about the structure of the barbecue, it is recommended to look at the photo/video. First you need to prepare tools and materials:
First you need to draw up drawings or sketches, which will indicate overall and auxiliary dimensions, as well as information about the characteristics finished product. Based on the developed documents, the type of support is determined: brick or metal legs. In accordance with this, it is prepared additional material(corner, pipe). If you are making a barbecue from a gas cylinder with your own hands, first initial stage determine the method of opening the lid. For convenience, a metal handle is used.
Preparation for work
Tip: Before you start cutting, you should make sure that there is no gas inside, otherwise the likelihood of an explosion increases.
Vapors of a gaseous substance may remain in the cylinder. To make sure that the container is empty, it is filled with water. If it is necessary to release gas and its vapors, follow the instructions:
- The container is turned upside down, then the valve is opened and it is completely emptied.
- Condensation remains inside. To remove it, the outlet of the balloon is lubricated with soap. Thanks to this, the process of condensate release will proceed more clearly: the liquid foams, and splashes appear under pressure.
- The structure must be freed from gas residues, for which water is poured inside. How to do this safely if there is still a valve installed at the inlet? You need to lay it on its side. Further work should be carried out together with an assistant. So, one person saws off a valve with a hacksaw, another pours water over the cut area, which helps cool the metal. As a result, the risk of sparks and ignition of residual gas is reduced.
- Now it is possible to pour water inside. This is done using a hose; it is also possible to use a funnel.
- At the initial stage of filling, it is recommended to shake the container, which will allow you to wash its inner walls, removing any remaining condensation.
- After filling the container with water, it is recommended to leave it for several days.
- The liquid is drained, and this should be done as far as possible from residential buildings due to the unpleasant odor.
If you plan to make a barbecue from a gas cylinder with your own hands, you can consider using a hammer. Use it to knock down the valve. However, this method is more dangerous. Due to the significant impact force, more sparks may occur. It is unlikely that it will be possible to eliminate their appearance by spraying metal.
Cylinder cutting
When the water has been removed from the container, you can proceed to the main stage - making a barbecue. To do this, remove rust from the gas cylinder, if any. Then they move on to cutting. If the hole layout is already ready, cut the metal with a grinder. To protect the flame from the wind in the future, it is better to leave the side rings. The cut should be as close to the weld as possible. Dimensions as in the drawing below. 
To make straight cuts, you must first mark them. If you need to get an open one, just cut it in half. In this case, the cut will also take place along the side rings. To make a barbecue from a gas cylinder with your own hands, you need to study the drawings, photos and videos of the entire process before starting work, because such a design is somewhat more complicated due to the configuration of the hole. 
All step-by-step instructions can be seen in the video.
You should be guided by the parameters: horizontal lines run along the center of the cylinder, along; vertical - parallel to the side rings at some distance from them (10–20 cm). Working with a grinder, move from the center of the cylinder to its edges. Considering that the length of the product is significant, the grinder disc may burn out. To avoid this, it is recommended to not cut the metal completely in some places. In these areas, the walls are removed with a chisel. To create the possibility of blowing the flame, holes (up to 10 pcs.) are drilled at the bottom and in the side rings.
Attaching the support
The barbecue is characterized by a round base, so you need to think about where the structure will be located. If you make a support from brick or stone, you will end up with a stationary product that cannot be moved when necessary. The preferred option is metal legs; they can be made from pipes or corners. If there is an unnecessary metal thing, for example, a support from an old sewing machine, it is used to install a barbecue.
There are two ways to attach the base to the bottom of the structure:
Or you can use legs from an old sewing machine. 
The height of the legs can be any. It all depends on personal preference. You need to be guided by convenience. Legs that are too low will not allow you to stand level at the barbecue; you will have to constantly bend over. It is better to focus on the average height of adult family members. At the same time, we must not forget that the cylinder is characterized by a significant height.
Welding hinges, lids, handles
Having secured the grill to solid foundation, move on to the next stage. To avoid the hassle of opening a hot lid, it is recommended to weld it to the bottom of the structure. If it is not removable, use loops. They are welded or secured with bolts and nuts. Rivets - not too much suitable option, because they can withstand average temperatures and can melt when exposed to an open flame. 
If you place the hinges in one direction, the cover can be removed in the future if desired. By welding them in the opposite direction, they act differently:
- the hinges are fastened on one side;
- then put on the lid;
- install the hinges on the lid on the other side and begin to weld them to the barbecue.
In this case, the design will be non-separable. To freely use the barbecue grill, fix the handle. It is located in the center of the metal cover. This element can be welded, which is more reliable, or connected using standard fasteners. The second option involves the need to drill two holes on the cover. This is where the handle is installed. It is desirable that it be made of metal. Wooden elements They will quickly burn out and may rot, since the finished product will be constantly exposed to the open air.
If the structure is used only as a barbecue, you can also weld a grate. It is usually located directly above the rounded bottom. The structure can also be used as a barbecue, in which case it is better not to attach the grill. A store-bought barbecue with a handle is installed on the ribs of the former cylinder. In this position, closing the lid will be difficult due to the protruding elements of the large grille. It is also made removable, but then you need to weld the corners near the edges. A grate is placed on their lower shelves. 
Well, and a video of all the work done.
You can even try to make everything in the form of a steam locomotive, as in the photo below. 
To prevent the lid from completely swinging open, you can weld a metal rod or chain. Due to this, this element is limited in movement. It is allowed to paint the barbecue, but it is better to do it outside. Interior still remains hidden from view. Use paints that are resistant to high temperatures. They must withstand up to 800?C. It is recommended to apply paint only after the surface has been coated with a special primer.
Many of us often have gas cylinders in our homes. They are made of fairly high-quality metal, which sometimes it’s just a shame to throw away. In order to get started, you will need a similar container of 50 liters. It is often left over from propane.
A little about security measures
You may not even realize it, but there will be residual gas inside. Of course, you can’t start working with them; you need to get rid of them. To do this, simply open the container and leave it for several hours. Just make sure there is no fire nearby. Also, after all this, rinse the container with water. It will completely rid the cylinder of gas residues. You can also use chlorine or lime for cleaning. The truth may remain after this bad smell. But it's easy to remove. Simply hold the product over the fire for a while. Wait until the paint burns.
Work process
From the resulting cylinder you can easily make a portable compressor station. Surely you have a large number of wheels on your farm. They need to be pumped up from time to time. So such a homemade invention will come in handy. Small wheels will make such a station as mobile as possible; you won’t have to carry heavy tires with you.
In order to get started, you must first find a reducer whose maximum pressure will be 2 atmospheres. With it, even children will be able to inflate tires without any problems.
Then you can build a stove without any problems. It will do an excellent job of heating the workshop. To create it, you only need one burner, which can heat up to 140 degrees and a small chimney. By the way, with such a device it is possible to easily dry nuts and perform many other manipulations. Look at the photos below to see what it all looks like.
One interesting thing to note is the vegetable garden skating rink. It can also be used as a track leveler. To do this, it is enough to simply prepare a special iron base that you can easily hold on to. You can make such a skating rink in just an hour, or even less. It all depends on how quickly you find the iron handle.
Lovers of outdoor recreation can also be satisfied. In particular, you can make a high-quality barbecue. To do this, simply cut out the top. By the way, it is possible to make a smokehouse without any problems by combining several cylinders at once. Look at the photo below. Looks quite attractive.
By the way, if you have any parts from the cylinder, do not throw them away under any circumstances. It is possible to make a stand for the burner from half. You just need to attach a few small legs. You can also use part of the side panel. It should be used as a protection for the sharpener.
As you can see, there are quite a lot of options. If you don’t have the desire to do anything complicated, then you can, for example, make an ordinary trash can out of a balloon and decorate it. In general, it’s enough just to show your imagination. Do you have piglets? Then just make a trough for them to feed. This is a great opportunity to save money.
The barbecue is an integral part of organizing trips to nature, relaxing at the dacha and receiving guests in country house. It has become a tradition for many families to gather together at the table to the fragrant smell of cooking barbecue. However, more and more often, men (and we know that they are the ones who prepare the best kebabs) do not so much compete in the quality of cooking meat as they brag about the functions and appearance of the technical “filling” of this process - the barbecue. Many people are no longer so interested in buying a “leaky box with legs”, but want to make something special. A brazier made from a gas cylinder, although at first glance seems like ordinary scrap metal, copes with its tasks much more effectively than other industrial designs. In this article we will consider in detail all stages of work related to self-assembly finished product, including the preparation of cylinders, their marking and cutting, and we will also provide useful tips on working with such homemade equipment.
When looking at such a work of art, you don’t immediately realize that this multifunctional grill is made from recycled materials
Advantages and disadvantages of a DIY barbecue
Gas cylinders are perfect for “rebirth” into barbecues and, in general, into any structures associated with heating. They are made of durable steel and have standard sizes, and they are easy to find at the dacha and in the garage or buy literally at a bargain price.
Advantages of a barbecue from a cylinder:
- Universal design. All models of gas cylinders are unified. There are not so many varieties that “something could go wrong.” Accordingly, finding a couple or three identical containers for creativity with a grinder in your hands will not be difficult.
- Heat resistance. The metal will not burn or deform even after prolonged contact with open fire.
- Multifunctionality. In this grill you can not only cook kebabs, but also bake vegetables, as well as smoke and fry.
- Safety. After cooking, you do not need to extinguish the coals with water. For these purposes, it will be enough to simply close the grill with a lid.
- Large volume. In such a homemade grill you will feed not only yourself, but also a large company. Especially if you spend energy welding a multifunctional unit.
- Availability. The main thing is to have a welding machine and a grinder at hand. This is a relevant point, because the price of a barbecue made from a gas cylinder, even taking into account the overpayment for some elements, will ultimately be lower than the cost of a purchased model.
One of the advantages of a homemade barbecue is the ability to create a mobile model, which, if you really want, can carefully and unnoticed by guests, along with snacks and you, move to another part of the garden For work, it is better to take a 50-liter cylinder. They have ideal dimensions for making a barbecue: its diameter is 30 cm and its length is 85 cm.
There are not many disadvantages, but they are also worth mentioning:
- In winter, the metal will cool down very quickly, so to invite friends to a barbecue, you’ll have to chip in for firewood. Since maintaining the desired temperature in the grill will be much more difficult.
- Unsightly appearance. If you don’t spend a certain amount of money on buying special heat-resistant paint, very soon your barbecue will lose its presentation.
- Toxicity. Before using a barbecue made from gas cylinders, it is necessary to get rid of any remaining rot and dirt that may have accumulated on the surface over many years. inside balloon. Therefore, before starting all work, the cylinders are carefully opened, and all parts are calcined over a fire, and only then do they begin processing and clean off the dirt.
How to prepare a drawing for making a barbecue with your own hands from a gas cylinder
Despite the fact that barbecues made from gas cylinders are considered to be quite simple devices in their design, before resorting to any work, it is better to draw a drawing. Pros do this using special 3D programs. Suitable for beginners simple drawings barbecue from a gas cylinder with standard dimensions.
Diagrams for marking the main technological holes and the design of a standard barbecue, barbecue, and smokehouse made from gas cylinders
On the drawing of a do-it-yourself barbecue made from a gas cylinder, you must indicate the dimensions of each component, which will help to correctly and accurately make the markings, and, consequently, cut all the parts. Such calculations will help determine how much material is required for the work, as well as understand in advance about connection options different elements designs.
One of the main mistakes of beginners is that they forget to mark the place under the ash pit. That is why you should not refuse to create such a “hint” that will help to correctly organize all stages of work.
At this stage, it is important to decide whether your design will perform one function or combine several. For example, for a barbecue you need to additionally cut out the lid. And for a full-fledged smokehouse you will need not two, but three cylinders.
What tools and materials are needed for the job?
To cut a cylinder, arm yourself with a gas cutter or grinder. During the work process, it is worth taking care of the availability the following materials and tools:
- Steel pipe with a diameter of 100 mm with a 90° elbow (for a chimney).
- Corners for fastening elements and strengthening the structure.
- Hinges – you can use elements intended for doors or furniture.
- Barbecue grill.
- Rivets, bolts and other elements.
A welding machine and an angle grinder are the main tools when working with metal. What tools and additional accessories you will need when working on creating a barbecue from a gas cylinder:
- welding machine;
- electric grinder;
- electric drill;
- drills designed for working on metal;
- clamps with which you can fix metal components;
- metal ruler;
- electrodes with a diameter of 3−4 mm;
- cutting and cleaning discs for grinders;
- scriber;
- core;
- adjustable and gas wrenches;
- set of wrenches.
How to make a barbecue with your own hands from a gas cylinder - step-by-step instructions with photos
Before starting any manipulations with gas cylinders, it is necessary to free it from residual gas. Even in an empty container, there almost always remains a suspension of liquid hydrocarbons, which can explode upon contact with air.

|
The first stage is removing the valve. First of all, you need to fix the cylinder on the ground. To do this, we “grab” it to the stop. Next, attach the gas key. |
|
We increase the “thrust” with the help of a steel pipe like this, it plays the role of a lever. We do this very carefully. |
|
After the valve is open, fill the container with water, or soapy water, and leave our container for several days. |
During this time, the water will have time to dissolve the liquid hydrocarbons, we fill the container again and drain it again. Now our cylinder is safe. And the next stage of work can begin.
How to mark and open a gas cylinder
If we are talking about a standard 50-liter cylinder, in these designs the outer diameter of the container is 96 cm. This value should be divided into four parts. When performing these actions, you will get a value of 24 cm. The marking should be done along the longitudinal seam. It is recommended to measure all distances from this line. This rule ensures even markings without distortions.
You will need to measure 24cm from the seam on both sides and draw lines. The main thing is not to cut them out along the entire circumference and leave a part sufficient for constructing the base of your barbecue.
Side seam marking option 
After cutting “according to the marks” you get the following blanks: We process the edges as evenly as possible to ensure maximum sealing of the barbecue container
At the place where the valve was present, a pipe should be installed, through which the smoke will be removed.
Preparations for the future chimney To ensure that the heat in your barbecue is distributed evenly and there are no leaks, you need to weld strips of steel strip at the joints of the lid and body.
This is how you can improve an ordinary cylinder using a pair of grates, an angle grinder and metal corners If you have not welded a corner for skewers inside the cylinder, you can insert it into the side parts of the grill.
To do this, you will need to make slits using a grinder. The ends of the skewer will be located in them How to make legs for a barbecue
High legs will also require additional fixation, which is provided by a welded corner. It should be placed on the outer perimeter. Attaching the legs can be very simple and a little extravagant.
For the manufacture of legs, angles or conventional welded pipe structures welded to the structure are often used. The main thing is to ensure the stability of the grill.
How to weld lids and handles and assemble the entire structure
The cover is usually created at the first stage of work on the grill or barbecue. After processing the edges, it is almost the first element attached to the main structure. The most difficult moment is not so much to attach the hinges, but to ensure a tight fit of the structure. Sometimes a thermometer is attached to the lid.
The hinges are welded at the beginning, but the handles are most often fixed after the final painting of the product. To ensure that the grill lid does not open all the way, you need to weld a piece of a 10×10 square onto the counter part of the curtain, which is located on the cylinder itself.
Such limiters allow you to control the tilt angle of the lid and protect the hinges from breaking. Mark the holes and slots for the skewers. We weld the barbecue guide. Don’t forget to decorate our “blower” a little.
It is better to provide holes in the base of the structure in advance. They will rid your grill of dust and dirt and remove excess moisture during the rain. In addition, additional holes will provide additional traction.
How to paint a grill
If you think it is possible to paint the grill regular paint, you are very wrong. Under the influence of high temperatures, a regular coating will turn into soot after the first heating. There are two quite obvious solutions. The first is to leave everything as is, and the second is to spend a certain amount of money on special heat-resistant paint.
However, before you run for a brush and to the store for paint, you need to make one very important thing. Burn some wood in our barbecue. This is done in order to destroy the remaining gas substances and degrease the structure.
It is better to burn the grill outdoors or indoors, where it will be as safe as possible. The surface of the grill can be covered different materials:
This is what our grill looked like after painting Let us add that the barbecue model discussed above is the base for many similar designs. Most craftsmen will improve their homemade products additional cylinders, thereby expanding the functionality of the device.
What else can be made from a gas cylinder - manufacturing nuances
Based on a gas cylinder, you can make dozens of variations of grills, barbecues and smokehouses. For convenience, we will briefly describe some of these devices:
- Outdoor grill from a gas cylinder. The simplest type of construction from a gas cylinder. Even a schoolboy can make such a grill.
How to make a smokehouse from a gas cylinder
Let's look at some of the features of making a smokehouse from two cylinders.
Illustration Description of action 
The base for a barbecue smokehouse made from a gas cylinder can be a stand for an old sewing machine or a welded structure like this. 
We think through options for mounting a retractable or folding table in advance. The design may vary. 
Prepare the cylinders following the instructions above. We cut each of them like simple barbecue roasters. It is better to make a smokehouse from a gas cylinder yourself according to the drawings. 
The only difference is that you need to make a hole in the firebox for a “blower”, which will allow you to control the smoldering process of the coals. Which, in turn, will create the smoke necessary for smoking. 
And we made such a multifunctional smokehouse from a gas cylinder with our own hands. Do-it-yourself barbecue from a gas cylinder
We discussed in detail an example of making a barbecue from a gas cylinder in this article. If you still have questions about how to make a barbecue grill yourself from a gas cylinder, watch this video:

Each compartment performs its own task. Such barbecues have high performance Due to the hermetically sealed design, there is virtually no heat loss.
If you decide to create a grill-steam locomotive, then from this video you will learn how to cook a grill from a gas cylinder.
Features of using barbecues assembled by yourself
Before you decide to create or buy similar product, pay attention to some points:
- First of all, understand that any structure that works with fire is potentially life-threatening.
- Ask yourself in advance where the product will be stored during the cold season.
- Study the principle of operation of the barbecue and its features. Every structural element has its own goals.
- Prepare all materials for work in advance.
- Do not leave small children unattended near power tools, much less around the cylinder.
- Consider the option of buying a barbecue from a gas cylinder if you are not entirely sure whether you can finish the work yourself.
