TwitterOr rather, not a weapon at all. In our time, it is difficult to imagine an army without thousands of vehicles both on the front line and in the rear. During the Great Patriotic War, everything was exactly the same.
Today's story is about a car that could often be found in the rear. Gasoline and diesel fuel, the blood of war, went primarily to the front. And in the rear it was possible and necessary to ride on what is at hand. This is where the generator comes in handy.
So, the gas-generating car ZIS-21.
Produced from 1938 to 1941, a total of 15,445 units were produced.
The ZIS-21 was a standard ZIS-5 truck with a NATI G-14 type gas generator. The gas generator ZIS-21 was manufactured at the Moscow plant "Kometa". Its gross weight was 440 kg. Hopper height 1360 mm, diameter - 502 mm. Weight of fuel in the bunker - 80 kg.
Wood chocks, briquettes from shavings and sawdust, waste from sawing, coal and peat briquettes, and even cones could serve as fuel.
The essence of the gas generator is simple at first glance. Incomplete combustion of fuel results in a mixture of hydrogen and carbon monoxide (CO). All this is filtered, cooled and enters the combustion chambers. The efficiency of the process reaches 75-80%, and on engines specially modified or specially designed for operation on generator gas, by increasing the compression ratio and slightly boosting the gas generator, almost equal power is achieved with gasoline engines.
Plus, in countries where there are no problems with forests, there are gas stations in every clearing. The main thing is dry fuel and the absence of rot.
The gas generator was mounted on the right side of the cab and attached to the right side member of the frame using brackets. The right door had to be made two times smaller so as not to reduce the body. But the passengers are not the main thing here, the main thing is the cargo.
Since the gas generator, mounted on the right side of the car, had a mass of more than 400 kg, the ZIS-21 had a reinforced right front spring - 8 mm thick sheets were installed instead of the standard 6.5 mm.
Coolers-purifiers for coarse cleaning and gas cooling, consisting of three cylinders connected in series with each other, were located across the machine behind the cab under the loading platform.
On the left side of the car near the cab, a fine filter of a cylindrical shape with a height of 1810 mm and a diameter of 384 mm was installed. To ignite the gas generator, a centrifugal fan driven by an electric motor was installed. On cars manufactured in 1938, the fan was attached to the bracket of the right footboard, and on the ZIS-21, produced since 1939, to the left footboard of the car.
For accelerated starting of the engine and for short movements, a gas tank with a capacity of 7.5 liters was installed under the hood.
The gas generator ZIS-21 had the following characteristics:
Engine 6-cylinder, in-line, 5555 cm3, 73 hp. On gas, however, the power dropped to 50 hp, but this was reflected in the speed, not the carrying capacity.
The maximum speed on gasoline was 60 km / h, on gas - 48 km / h.
Load capacity 2,500 kg, minus fuel.
One charge of the bunker was enough for 60-100 km of run, depending on the type of wood being charged.
Of course, "gasgens" were not used from a good life. However, during the war they released a significant part of the gasoline for the needs of the front. From Kolyma to the Urals, thousands of "Gazens" transported hundreds of thousands of tons of cargo, puffing their generators. And moved on time, judging by the results.
By the way, in Europe (England, France, Germany), gas generators were also used quite normally, even in cars. But this is completely different.

People have been showing for a long time.
At the same time, there is an opinion that many developments are just an “echo” of the past, which today has lost its relevance.
Not at all. Moreover, the opposite is true.
The price of fuel is constantly rising
The high cost of gasoline and diesel, as well as rising gas prices, are forcing people to switch to more economical types of fuel.
The principle of operation here is simple. The engine does not run on gasoline, diesel fuel or ordinary gas (methane, propane), but on the gas released when wood is burned.
Devices that allow you to produce such a gas are called gas generators.
In addition to the domestic sphere, they are very popular and have long been used in industry.
As for the manufacturing methods, they differ. In this article, we will consider the most popular of them.
Method number 1
In the classic version, the gas generator is made from the following elements:
1. Hulls.
This part of the design is the main gas generator. Inside, as a rule, the main components of the boiler are installed.
The body can be assembled from steel sheets or corners. All that is required is to pre-mark them according to the drawings and templates.
2. Bunker.
This container is designed to contain alternative fuels such as firewood, pallets or charcoal.
You can make a bunker from sheet metal, after which it is fixed in the casing of the device.
For compactness, the place for the hopper is allocated directly in the body. The only requirement is to delimit the two nodes with mild steel plates.
3. Combustion chambers.
This structural element is located at the bottom of the bunker. The main task of the assembly is to create a high temperature, therefore, heat-resistant steel must be used as a material for manufacturing.
The lid of the hopper must be sealed to prevent oxygen from entering inside.
4. The neck part of the combustion chamber.
A special area where resin cracking occurs.
This part of the chamber must be separated from the main part of the body using special asbestos gaskets.
5. Air distributor boxes.
A part that is outside the main body. In this case, the air distributor fitting must be cut in using a non-return valve.
The purpose of the node is to ensure the normal flow of oxygen into the combustion chamber.
At the same time, combustible gases are retained in it (chamber).
6. Filter elements and nozzle.
The task of these elements is to combine the neck of the chamber in which the fuel burns with another chamber where the olefins burn.
7. Grate.
A product that will perform the function of separating doors, beams and coals in the combustion chamber.
By the way, the door helps to ensure normal access to the inside of the case.
After preparing all the elements, the assembly of the gas generating plant is carried out.
Below is the general layout of the device using the UralZIS-352 gas generator as an example.
The sequence of actions is as follows:
At the final stage, it is worth attaching a water “shirt” to the boiler body with an air outlet and air supply fitting mounted on it.
It is in this "shirt" that the coolant will circulate.
The shirt can be placed in two places. This may be the olefin combustor or the double-walled vessel itself.
Method number 2
When creating a gas generator for a car, the main emphasis is not only on the reliability and efficiency of the device, but also on its compactness.
Abroad, the cooling filter, cyclone and body are made of stainless steel, which allows the use of metal that is half as thick.
Naturally, this design is much easier. In our conditions, old propane cylinders or fire extinguishers are used to reduce the cost of construction.
Liquefied propane tanks are often used to make an outdoor tank.
The manufacture of the inner part is made from the receiver of a truck, for example, KAMAZ or ZIL.
Particular attention should be paid to the grate - it is made of thin metal, and the pipes are made of ordinary pipes (the main thing is to choose the right diameter).
The upper part of the cylinder is used to make a cap with fasteners. In extreme cases, the part can be made of sheet steel.
The lid is sealed with a special cord treated with graphite impregnation and made of heat-resistant asbestos.
To make a coarse filter, you can use an old fire extinguisher or do it even easier - take a piece of pipe.
In the lower part, a nozzle in the form of a cone must be made, which is necessary for the shipment of ash.
On the upper part, the end should be tightly closed with a lid (as a rule, it is welded).
An outlet pipe is mounted in the cover itself, and on the side there is another fitting for supplying combustion products.
The gases emitted by the gas generator have a high temperature, so they require high-quality cooling.
There are two reasons for this:
- firstly, gases heated to a high temperature are characterized by a minimum density, which makes the process of its combustion in the internal combustion engine cylinders practically unrealistic;
- secondly, there is a risk of a spontaneous flash in the event of gas contact with hot engine elements.
During the ignition process, it is important to ensure the normal movement of gas along the path - this work is taken over by the fan.
Already after starting the motor, the working composition moves due to vacuum, so there is no need for a fan.
As a cooler, you can use standard heating radiators. The main thing is to position them correctly and ensure maximum contact with air masses.
In some cases, the installation of bimetallic radiators is allowed.
Gas fuel must be cleaned before being fed into the engine - this is ensured with the help of special filters.
We must not forget about another important element - the mixer. With its help, the volume of the supplied gas-air mixture is regulated. The adjustment is made using a damper.
Method number 3
To implement the following method, you need to prepare a 4.25 inch (14 cm long) stainless steel tube and a five gallon tank. Instead of a pipe, you can use an old fire extinguisher.
As a gasket, you can use a silicone gasket, with which you can effectively close up all existing cracks and seams; 
In today's world of rising utility costs, everyone is looking for ways to save money. And this is how the wood-burning internal combustion engine was developed and implemented. Today, this design has been improved, due to which it can be found in many places. Moreover, the most interesting thing is that these installations are used not only in enterprises or private homes, but even in cars. Therefore, today many are interested in whether it is possible to make gas generators on wood with your own hands? Here on this question it is possible to stop and in more detail.
Principle of operation
In order to understand how to properly use the generator at home, it is worth understanding the basics of its operation. This will allow you to understand whether the costs of materials are worth the investment, and how quickly they will pay off. In addition, the gas generator has its own scope.
By itself, this device is a complex of components and assemblies that provide gas production from solid fuel. The resulting material is used in the internal combustion engine. But there is a caveat: the design of generators may differ from each other - it all depends on the type of solid fuel.
One of the most common, and, perhaps, affordable types of fuel is firewood. When wood is burned in a sealed space, combustible gases such as carbon monoxide, hydrogen, methane and other unsaturated carbons are produced in the process. This mixture additionally contains ballast gases - oxygen, water vapor, carbon dioxide and nitrogen. But the efficiency of the gas generator depends not only on the production of such a combustible mixture. It must become suitable for use for specific purposes. Therefore, the whole process goes through the mandatory steps:
- Gasification. Here, solid fuel must completely burn out and go into the smoldering stage. This process occurs with a small amount of oxygen - 30-35%.
- The first and second stages of purification. All volatile substances that have been obtained after smoldering are separated using a dry vortex filter-cyclone and fed into a separate chamber - a scrubber. Here water is already involved, which conducts another cleaning of the combustible stream.
- Cooling. In the process of burning and smoldering, all substances acquire a sufficiently high temperature - from 700 degrees and above. To lower their performance, an air or water heat exchanger is used. After that, the mixture will have to go through another purification.
- Sending. After all stages, the resulting finished substances can be pumped into the distribution tank using a compressor, or immediately enter the internal combustion engine.
In fact, the full cycle is quite complex, and therefore takes time. But the main node is the gas generator itself. Basically, it is a cylindrical or rectangular metal column, with a narrowing at the end. The internal structure has several air pipes through which oxygen is pumped in and gas is released. In the upper part there is a cover through which firewood is loaded.
If you don’t go deep into the basis of chemical processes, then the process of gas production looks like this: they loaded the fuel - it burned out / rotted - a gas mixture was obtained. In order for the final product to have the necessary properties, there are many nodes inside the structure that clean and cool the mixture. If we talk about home gas generators, then you can use a simpler design. This is both easier and cheaper.
Pros and cons of "home" gas generators
Before you take on the self-assembly of the device, you should understand for yourself whether it is really needed in the household. Yes, this type of generator is economical in terms of fuel, especially if you live in the private sector and have your own garden. But, nevertheless, you need to be more objective.
The strengths of the gas generator are:
- high efficiency - it varies between 80-95%, and in fact, for solid fuel boilers, it reaches an average of 60%;
- long burning - this moment allows for a more rare laying of fuel (firewood burns for about a day, and coal can smolder for 5 days);
- in the process of burning firewood, almost 100% combustion occurs, so the need to carry out a general cleaning of the ash pan and flue occurs much less frequently;
- if desired, you can make the whole process automated;
- during combustion, no harmful substances appear, so the installation is safe, both for the environment and for the owners themselves;
- the gas generator allows you to save on heating the house;
- wood is one of the most accessible materials, both in a paid and free sense (you can buy firewood, or you can dry the cut branches yourself);
- for heating, you can use not only firewood, but also wood waste - chips, sawdust and other cellulose-containing materials;
- the gas produced is great not only for heating a house, but also for keeping an internal combustion engine running in a car, and even for generating electricity;
- if desired, you can create a container in which impressive logs (up to 1 m in length) will be placed, which means that they will burn longer;
- there are factory models that allow you to use fuel with high humidity (up to 50%) or even freshly cut logs - although it is difficult to make a home installation of this nature.
Many experts believe that the gas generator is much safer to operate than solid fuel boilers.
But for the sake of justice, it is worth mentioning the disadvantages of such units. Firstly, in order for the fuel to smolder in the right way, a forced air intake is needed. So, the installation will need to include a fan. But this element is powered by electricity, so if the light is turned off, the generator will not be able to work. Secondly, if for some reason the power decreases (by more than 50%), then the device will begin to emit tar. And this substance has a sticky consistency and will quickly pollute the flue. If the gas generator is used for heating, then the owner must control the temperature so that it does not fall below 60 degrees. Otherwise, condensation will form quickly.
If you look into the shops, you can see that gas generators are very expensive in price, unlike solid fuel boilers. That is why, in order to save money, you can think about how to assemble such a unit with your own hands. The main thing is to choose and prepare those materials that are durable and able to withstand high temperatures. In no case can you save on this issue, since the safety of operation depends on it.
Creation of a gas generator
The construction of the unit should begin with an acquaintance with what drawings of wood-burning gas generators are. This will allow you to understand what kind of work lies ahead and what is needed for it. Even though a home-made device will cost less than a factory one, you will also have to spend money here.
Many people are building a generator because it's cheaper. But there are costs involved too:
- cast iron for a grate is a rather expensive material, but it has the necessary characteristics;
- a special spring that is best suited for making a cover;
- heat-resistant gaskets for hatches and combining individual components;
- fan - you will not only need to purchase it, but also prepare for the cost of electricity, which will power it.
The gas generator can be used in two cases - for the house and for the car. The drawings of these structures will differ, since in the latter case, the structure should have a lighter weight and small dimensions.
In fact, the closer the device in its dimensions and design to the industrial model, the higher the efficiency of its work. But there is no need to make an exact copy. The gas generator must have the following elements:
- Frame. Such an element is also called a filling chamber. The shape may resemble a cylinder or a rectangle. To make the case easier, you can take a finished metal container and grind it a little. But you can start from scratch. In this case, you will need sheet metal (thickness 8-10 mm) and a corner. It is advisable to use mild steel. For safe operation, legs are welded from the bottom of the body. An additional circle of steel is welded in the upper part, which will serve as a cold air intake.
- Bunker for fuel. This element is made in the same way as the body, moreover, from the same materials. The bunker must be made smaller so that it can be fixed inside the housing. If there is no desire to mess around for a long time, then you can simply divide the space of the case into sections using metal plates. The volume must be at least 0.7 cubic meters. You can mount here and the hatch. It will help control excess fuel and, if necessary, will “throw off ballast”.
- The combustion chamber. For such an element, heat-resistant steel is needed, because it is here that the process of combustion and smoldering will take place. An alternative option is an empty gas cylinder from household gas. Bolts are used for fixing.
- The neck of the combustion chamber. Resin cracking occurs here, so the neck is separated with heat-resistant gaskets. Asbestos gaskets will do, but if possible, it is better to invest in safer materials.
- Air distribution unit. To connect this node to the rest of the structure, use a fitting. A non-return valve is mounted next to it, which is responsible for regulating the air flow to the firewood. The valve also prevents leakage of the resulting combustible mixture. Between the air distribution box and the middle part of the chamber, calibration holes are made - tuyeres.
- filter unit. At this stage, the mixture that enters through the pipe from the air distribution unit should be cleaned. For a cyclone filter, you can use the body of an old fire extinguisher or other similar container.
- cooler. In the home model, you can use, for such purposes, a conventional radiator or make a special coil. The resulting mixture will move along a long structure and gradually lose heat. If there is a desire, then water cooling can be done.
- Separator. Since the incoming air will be cold, and high temperatures are planned inside the generator, it is not possible to avoid the formation of condensate. But so that it does not interfere with work, a separator is installed, which will take it away from the installation. For this purpose, a plate with ribs is inserted into the pipe (diameter 3-5 mm) and fixed on the “skirt” (cold air entry point). The lower part is equipped with a condensate drain valve.
- Grate, doors and other elements. Cast iron is best for grating. The middle part of such an element is made movable or removable, so that in the future it will be possible to clean it more easily. Although the presence of doors makes it more convenient to operate the gas generator (loading firewood or cleaning the combustion chamber), they must have airtight seals.
One of the important conditions for the operation of the gas generator is tightness. Therefore, the lid should fit as tightly as possible to the body. Since this element serves as an entrance to the loading chamber, it is best to equip it with a shock-absorbing spring. This will make it easier and safer to open and close the lid.
In theory, it is believed that a home-made gas generator can work with wood with a moisture content of up to 50%. But, as practice shows, the higher this indicator, the lower the efficiency of the installation. Therefore, it is best to stick to the threshold up to 20%. Although it is possible to fix this problem. To do this, the annular hose is placed in the space between the walls of the housing and the outer side of the hopper. This will allow transferring part of the thermal energy to the fuel.
The best option would be if you make a gas generator from the body of an old boiler. This will help to keep the proportions for a particular house. But when this is not possible, then you can use old gas cylinders, or purchase a completely new metal. There are many opportunities to save money, the main thing is to calculate and assemble everything correctly. That is why you need to follow the drawings.
People invented electricity, learned how to use solar and wind energy, extract various minerals, such as oil and gas. However, most of them still continue to burn wood in furnaces. Sawdust and other waste from the woodworking industry can be used if you make a gas-generating car on wood with your own hands. Many masters today successfully operate such devices.

The principle of the car
A feature of the gas generator for a wood-burning car is the unit in which the gas mixture is extracted. Then it enters the internal combustion engine, where it is burned. As a result of these processes, the machine moves. When using such a device, it must be taken into account that it takes up a lot of space and requires the use of additional equipment- filters, pipes and radiator.
A gas generator is a device that turns wood into gas. Everyone knows that gas is an alternative energy source for cars. This is confirmed by a large number of gas stations. However, getting fuel on your own is not only possible, but quite real. The onboard structure is capable of producing as many resources as the vehicle needs. However, there is one caveat: hot fuel is less efficient, especially if impurities are present in it. Therefore, the first step is to cool it, and then clean it.
After leaving the unit, the gas moves through the pipes to the filter, and then to the radiator. During movement, it is cleaned of dust and acids. In addition, its temperature decreases. In the process of passing through the labyrinths, impurities settle on the walls in the form of liquid or solid particles. Through a special tee, the gas is combined with oxygen and sent to the engine. Then the mixture reaches not only the required condition, but also ends up in the engine. After that, the gas enters the combustion chamber and sets the car in motion.
The suspension, interior, engine and clutch of the car remain in place. The only problem is where to place the gas generator and how to lay the pipeline so that the machine looks like a steam locomotive. All these questions should be studied in detail before starting work.
The essence of the gas generator
It is quite possible to make a car on wood with your own hands. The manufacture of a gas generator is a feasible task, however, as well as its installation. To begin with, it is important to understand the features of the unit and the essence of the process. The design itself is presented in the form of a cylinder narrowed at the bottom. Figuratively, you can call it a bunker, a store for firewood in which is a cylindrical part. In the narrow half, combustion occurs.
The workpieces themselves fall under the influence of their own weight. This ensures an uninterrupted supply of fuel to the combustion source. Ash settles in a special container, which periodically requires cleaning. Firewood is loaded into the hatch from above.
Small workpieces are tightly placed from the grate to the lid. The latter is hermetically sealed to minimize leakage. The device is kindled, after a while the car can hit the road.
The design should not be confused with an open fire. The oxygen required for combustion is supplied in portions through a special tube. On the opposite side there is a hole for the gas outlet. With portioned air supply, active combustion is not carried out. Wooden blanks undergo pyrolysis - they smolder on low heat, actively releasing a combustible mixture.
Wood burning car - made in Donetsk
The main purpose of the gas generator is to produce a combustible gas called carbon monoxide. It is this substance that will burn in the internal combustion engine. This procedure can be positioned as complete and partial combustion, during which carbon monoxide is formed. In addition, carbon dioxide is released. When burned in contact with moisture, firewood forms a mixture that consists of:
In addition, during the combustion process, several non-combustible components are released. These include:
Types of structures
There are three types of gas generators for a car. If oxygen is supplied from the bottom, and gas is taken from above, this is a direct-flow product. With such an arrangement of nozzles, the gas mixture is released during combustion at the bottom of the cone. In the process of movement of gases through coal and chocks of wood, air and heat are released. After the blanks are passed through a hot gas mixture, they are dried and prepared for pyrolysis.
If the supply of oxygen to support combustion is carried out at the beginning of the narrow part of the bunker, and the gas mixture is taken from below, then this type of device is called reverse or overturned. The wood is ignited inside, above the grate zone. Pipes for gas removal are located below the grate. A similar principle of operation is similar to a smoking pipe.
There is also an alternative option - the combustion chamber at the reverse gas generator is limited by a special inclined partition. Opposite the oxygen supply pipe, on the back side of the partition, there is a niche from which combustible gas is taken. Oxygen supply and gas exhaust pipes are located on the same level. The pipe supply line crosses the bunker across, so this design is called horizontal.
3) Do-it-yourself wood-burning gas generator #3
Direct-flow and horizontal gas generators have shown themselves well when using peat, charcoal or coke. The overturned type of equipment is widely used for riding dry wood chocks.
Device Features
A characteristic feature of all gas generators is the movement of carbon dioxide (carbon dioxide) through decaying coal. In this case, the gas mixture gives off excess air and is converted into carbon monoxide. It is desirable that a cyclone filter be placed between the heat exchanger and the combustion chamber. This is necessary to ensure that the gas mixture is purified from all kinds of mechanical impurities. Such a device can trap about 90% of flying dust.
The radiator plays an essential role. Cooling, the gas becomes more concentrated and decreases in volume. This contributes to the supply of more fuel to the internal combustion engine. Engine power during operation directly depends on the temperature indicators of the gaseous mixture. This is because the gas is resistant to detonation, so it must be cooled to increase compression.
A fine filter element made of two canisters is considered compact. Mineral wool and slag in granules are placed inside the tanks. They will clean the gas well. At the bottom of the filter and heat exchanger, it is imperative to install taps. This is necessary to drain the condensate. After cleaning and cooling of the gas mixture, dew falls. Every 200 km of driving, about 3 liters of liquid is collected in the tank.
Welds and joints must be sealed, because in the event of a leak with the constant addition of firewood, the speed and performance of the car engine will remain at a minimum level. The assembled unit must be well fixed so that it does not collapse from vibration during movement.
do-it-yourself gas generator for cars
A wood-burning gas engine for a car can be of various shapes and sizes. There are no specific requirements for these indicators. However, it must be borne in mind that the device must necessarily be created from metal with a thickness of at least 3 mm. Where exactly to install the structure, each motorist decides for himself.
When choosing a location, it is important to consider not only the dimensions of the entire unit, heat exchanger and filters, but also the length of the nozzles. It is important that the batch of fuel is loaded through the cover from above. While the engine is running, refueling is carried out with a slight emission of gas. If the internal combustion engine is turned off, and the mass continues to burn in the device, loading a new batch is accompanied by the appearance of a plentiful cloud.
You can place such a device only outside the car and always behind. This is because the structure must be freely accessible. The longer the planned distances without refueling, the larger the dimensions of the product. The constituent elements of the apparatus must be made in accordance with the dimensions of the hopper.
The gas generator on a truck can be placed between the cab and the board on the driver's side. Pipes, heat exchanger and filter element may be placed behind the cab. The fine filter should be located on the opposite side of the cabin (behind the passenger door). For convenient removal of condensate, pipes and drain valves are led below the fine filter element.
On a passenger car, it is recommended to install the device on an open part. To do this, you can modify the trunk, weld a trailer, etc. It all depends on the taste preferences and fantasies of the owner. It is not recommended to install the equipment in the trunk under the lid, since during its operation smoke and coal dust will enter the car interior.
Gas generator - unit which produces combustible gas. After running the latter through cleaning filters and a cooling radiator, a clean and cold gas mixture is obtained. Carbon monoxide can replace the classic fuel option, keeping the engine running smoothly. Gasoline internal combustion engines operate with a gas generating device without significant performance losses.
DIY manufacturing
The production of any device begins with the production of a drawing. After studying the detailed information, a person has an idea of \u200b\u200bthe external design of the unit. Then it remains to bring your idea to life.
To make the device look aesthetically pleasing, you should choose the right details . For its manufacture you will need:
First you need to make 5-6 holes at the top of the pipe. It will become the top of the structure. An oxygen supply tube should be welded to one of the holes obtained. The rest will release gas. In the lower part it is necessary to weld a perforated stainless steel bottom. Get the grate part, which will accommodate the coals. Dust will come out through the holes.
From the inside of the resulting glass, a metal cone is welded to supply coal. Then a metal sheet should be welded with a hole the size of which matches the inner diameter of the pipe. The structure must be placed perpendicular to the top of the tube. The sheet will become the bottom of the bin. The functions of the latter will be performed by a can.
The resulting workpiece is placed in a barrel and welded in such a way that there is room for ash below, and the neck of the can is placed above the barrel. Then one of the can holes must be aligned with the combustion chamber and connected with an oxygen supply tube. Further, a metal sheet is welded in the upper part, which covers the difference in the size of the neck of the can and the barrel. The structure is ready.
Making a car on wood with your own hands is not as easy as it might seem at first glance. The procedure requires a lot of effort and time. However, for a skilled craftsman who is ready to experiment and is not afraid of difficulties, this is a very real task. It is very important to study in detail the device and the principle of operation of the product, as well as to correctly draw up its drawing.
