Do-it-yourself oven from machine disks. Do-it-yourself oven for a cauldron from automobile disks. Features of the future design

Being in the garage most of the time, many people think about creating heating system in room. Trying to save money, specialists in welding have invented the most cheap way ensuring the proper level of heat at any time of the year.

With old car wheels, you can special efforts with your own hands to create a stove in the garage from disks. We will try to tell you how to properly weld the oven, and what is needed for this.

A stove made of wheels is capable of heating a room measuring 15-17 m2. It is used, despite the specifics of the selected materials, not only in the garage, but also to provide heat in other utility rooms and baths. The main advantage heater considered availability and high quality material.

The discs are made of strong and thick steel, which ensures a long service life. In terms of quality, the wheels are in no way inferior to boiler steel in sheets and profiles.

In addition, the garage oven practically does not dry the air, and the metal high temperatures ah does not emit harmful fumes. The environmental friendliness of the material is due to the fact that the discs are made of specialized steel that is resistant to corrosion.

Materials and equipment for work

When welding a furnace from car rims, the following list of materials and tools is used:

• disks of a truck or car in the amount of 2-4 pieces;
• welding machine;
• welding mask;
• gloves;
• pipe with a diameter of 16 cm, length about 3 meters;
• chimney;
• metal sheets to create air reflectors;
• metal legs in the amount of 7 pieces;
• hinges and handles for creating a door;
• fuel tank.

When creating a combined and other types of oven, additional materials may be required.

Fire safety rules for arranging homemade stoves

When creating a furnace from car rims, the rules fire safety are quite a hot topic. The technology for the production of disks for wheels did not initially include the use of these for other needs, especially as a home-made oven.

Ovens from discs cannot be made on waste oil, since metal not rated for welding can burst, and boiling oil with highly toxic gases will flow through the crack. Since it is impossible to turn off the furnaces during mining, it is worth waiting until the oil burns out.

In order to avoid disastrous consequences, it is recommended to cook a car rim stove only on solid fuel.

Scheme of a long-burning furnace.

You can create a completely safe horizontal potbelly stove from disks by adhering to the following rules:

1. The weld seam must be smooth and without defects.
   Otherwise, smoke will escape through the cracks and fill the room. In addition, during operation there is a risk of failure of an incorrectly welded furnace.
2. To improve quality, it is strongly recommended to weld 2 parts at a time.
3. After each seam is made, the welded parts must be given time to absorb residual internal stresses.
   It will take from 3 minutes per kilogram of the mass of the elements to be welded. Further welding is recommended to start no earlier than when 3-4 cm from the end of the seam to the metal can be touched with a bare hand.
4. A day after the installation of the parts, the stove is subjected to a test run for the absorption of residual stresses.
   This requires from 3 hours of burning at full power with an open air throttle.

To ensure fire safety, it is necessary to close the oven door tightly, as well as to place quickly flammable objects away. When leaving the room, it is important to completely extinguish the stove and clean the chimney in time.

How to make a stove from disks for a bath with your own hands

Most difficult option do-it-yourself potbelly stoves from disks are considered to be a heating structure in a bathhouse. It is used to create a medium-sized sauna with warm, moist air. At the heart of the stove for a bath is a brick firebox.

The structure of the heating system is somewhat more complicated than that of a simple horizontal potbelly stove made of disks, but it is quite possible to do it yourself.

First lay a brick firebox. In calculating the dimensions of the masonry and foundation, they proceed from the diameter of the wheels. Typically used wheels cars, therefore, the dimensions of the firebox are on average 625x625 mm. Under it should be a cast foundation.

Functionally, the firebox is divided into 2 parts, so you need to think over the masonry in advance. Cold air from the locker room should come from below, solid fuel materials should be thrown from above.

Drawing of a stove from disks for a bath.

After the firebox has been built, they begin to weld the structure. It consists of 4 disks. At the bottom, struts and a reflector are installed for a uniform and smooth flow of air, as well as quality heating containers.

The third disk is welded so that stones can be placed inside, and a metal pipe to remove smoke. The third and second disks are connected by legs to fix the structure. The smoke transfer pipe is attached to the bottom of the third wheel.

In the second disk, an air divider is installed on top, which is necessary for heating water. The divider is mounted on 2 metal legs. The top disk is a supply reservoir warm water. A pipe of convenient length is attached to it, and a faucet is also mounted.

In the center is a pipe for removing smoke. The chimney is fixed to the support platform with struts. Under the support platform is a sheet of galvanized iron.

This general scheme welding of the furnace from disks. Let's consider in more detail the nuances of creating separate parts designs.

Water tank

The water tank is made from one wheel. To do this, it is necessary to weld the bottom and the upper part so that a hole remains in the center corresponding to the diameter of the pipe, the standard is 16 cm. It is also important to make an even and accurately made seam, otherwise water will flow out of the tank, and the reliability of the design is called into question.

After welding the container, you need to weld the pipe and check the quality of welding by collecting water there.

Arrangement of the heater and the upper part of the firebox

For complete and high-quality heating of water and stones, each intermediary disc must have a divider or reflector. The heater is a container with a pipe in the center to remove smoke. It is necessary to completely weld the bottom, install the pipe and attach the container to the top of the furnace.

A pipe is attached to the third disk - the upper part of the furnace - with the help of casings, and an air divider is installed inside to heat the tank.

Foundation and brickwork

The foundation of the furnace must be monolithic and slightly extend beyond the boundaries of the furnace. The average dimensions of the foundation are 700x700 mm. The firebox is divided into 2 equal parts: at the level of the dressing room floor, from where fresh air and at the level of the steam room, where solid fuel materials are thrown.

In both cases, metal doors are attached, and a combustion structure is installed between the levels.

Stove assembly

Scheme of the furnace in development.

The assembly of the stove should begin with laying the firebox and welding the elements. First, the internal parts of the structure are installed - a divider and an air reflector, then the bottoms are welded to the structures for water and stones.

Then the smoke exhaust pipes are installed, after which the remaining elements are attached to each other. After complete assembly of the structure, it is necessary to carry out a mandatory test run of the furnace.

A properly welded stove will not allow smoke to pass through, and will ensure uniform heating of the containers. High-quality masonry will ensure constant air circulation, which contributes to rapid heating and long burning.

Outcome

Creating an oven from car rims is a complex and time-consuming process. The base material is not rated for welding, and therefore the use of such furnaces with poor assembly quality can be dangerous. Furnaces of this type should work on solid fuel materials, and only experienced welders can create them.

In general, creating a stove from car rims is an economical and quick option for heating a garage or bath. What type of oven do you consider the safest? Share your opinion in the comments!

Having set out to make a stove on their own, people often use improvised material.

Remarkably for the construction of a heating structure, rims are suitable - iron part of a car wheel. Thanks to quality and thickness of metal they are perfect for this purpose.

Advantages of car rim stoves

The advantages of such a furnace are obvious:

• no need to spend money on materials;
• metal resistance to high temperatures and fire makes it possible to use any type of fuel;
• many options for disks will allow you to build a furnace optimal sizes;
• the material has a high heat transfer;
• the thickness of the metal increases the durability of the unit;
• quick and easy device design.

From rims You can make several types of heating design:

• for a bath;
• for a cauldron;
• brazier;
• potbelly stove.

Making a stove for a bath with your own hands

The construction of the furnace includes preparation and the manufacturing process itself.

The use of disks from a truck

If all of a sudden you got only rims from trucks, don't worry - they are also suitable. The furnace of them will last even longer due to the thickness of the metal.

Important! Disks are taken only steel, alloy wheels are not suitable for these purposes.

Required inventory

For construction heating unit will need:

• 4 identical wheels right size;
• Bulgarian;
• welding machine;
• thick sheet of metal or furnace insert;
• legs (optional).

Scheme of a bath stove made of KAMAZ rims, drawing

If we take disks from trucks, for example, Kamaz, then with the life of the device will increase by two to three times. The essence of this construction is that 4 disks are stacked on top of each other and fastened with a welding seam.

Photo 1. Drawing of a furnace for a bath from automobile disks. Includes firebox, heater, water heating tank.

First disc serves as a firebox: a window is cut out in it for laying fuel and a door is attached. Second disc serves as a stone. Third used as another heat exchanger, fourth is a hot water tank.

If necessary, to give the structure stability, metal legs are welded.

Preparation

Take the right size wheels, clean off any dirt, rust, or flaking paint residue. For this roast them at the stake And brush over the metal. Decide which of the disks will be at the bottom of the structure. Make a chalk mark for the furnace hole.

Furnace building process

1. The bottom two disks will serve as a combustion chamber and a heater. For the firebox, a window is cut out approximately 20 by 12 cm. It is important here not to cut close to the edges - step back from them along 2 cm, and the structure will not lose its strength. Next, the second disk is welded, and a grate is installed between them, on which the stones will be located.
2. The water tank must be made airtight, so the disk must be welded sheet metal bottom. A water faucet is installed on the side.

1. Further, all the individual parts of the structure are welded together.
2. Place a furnace insert or a plate cut from an iron sheet on the bottom of the combustion chamber.

That's all - the oven is ready. Legs can be welded to it if desired.

First, make cuts along the intended contour, and then cut through to the end. Be sure to sand the edges of the cuts, not to get hurt.

Reference. When cutting a furnace hole, difficulties often arise. The metal is thick and the disc is constantly falling or spinning. The advice is simple - use a vise. Clamp the disk in them and cut a hole.

Having completed the design work, it would be nice to paint a new stove heat resistant paint. But only cooled metal can be painted, so wait until the structure cools down. The black unit looks best.

Advantages of the disc oven

1. The main advantage of the disc oven is its mobility. It is not heavy, easy to carry and put anywhere.
2. Another feature is the welded construction. will not warp or crack.
3. The device is very heats up quickly and gives off heat well.

Photo 4 Also, the device can be used as a barbecue.

1. It is important to lay in the place of welding quality seam- there should be no noticeable defects on it.
2. When working with a welding machine, you can not immediately try to weld everything - work is being done in stages. Having welded the parts together, you need to wait for the seam to cool to the touch temperature.
3. When assembling the structure, do not forget that for correct operation furnaces are important to provide size of the combustion chamber according to the type of fuel that you plan to use.
4. After completion of work, be sure test the design and eliminate the identified shortcomings.

Attention! All welding work must be carried out in compliance with safety regulations, V protective clothing and mask. Do not touch the parts until they have cooled down.

If you have a small bathhouse, a garage or a workshop on your site, which you use infrequently during the cold season, it makes no sense to build a full-fledged brick oven. Such a design will take up a lot of space and require an impressive amount of money. Construction Materials and the work of the stove. But there is also alternative solution- a stove made of car rims, for the manufacture of which with your own hands it will take only a couple of hours of work and worn-out wheels.

In addition to the availability of the main components, a homemade oven has a number of advantages:

• Simplicity in construction.
• Compact dimensions that you can choose yourself, based on the diameter of the discs.
• Fast heating and good heat dissipation.
• Durability due to thickness and good quality become.
• Resistant to deformation even with prolonged exposure to humidity and high temperatures.
• Possibility to use different kinds fuels - wood, coal, fuel pellets.

Of the shortcomings, we note following points. Firstly, metal is a good conductor, and the furnace becomes very hot when heated, which can cause burns and injuries. And secondly, the disk oven cools down as quickly as it heats up - approximately 1.5-2 hours after the last batch of fuel burns out. Therefore, it should not be considered as a permanent heating device, but for heating a bath or utility rooms will be just right!

Note! Even a large disc sauna stove truck can heat a room with an area of ​​​​no more than 15 m2. Therefore, for large rooms you will need a more powerful device.

Materials and equipment for work

To make a stove from rims with your own hands, you will need the following set of tools:

1. Bulgarian with circles for metal or gas cutter.
2. Welding machine and electrodes.
3. Protective devices: goggles, leggings.
4. 2 cuts of 50 cm metal pipes 5 mm thick and 160 mm in diameter.
5. Iron sheet8 mm.
6. Door hangers (can be replaced with large bolts and nuts)
7. Refractory brick.
8. Cement-sand mortar for masonry and clay.
9. 4-6 steel channels.

To build the hull, you will need 4 disks from a truck, such as KrAZ. From such wheels you get a stove with a diameter of 0.5 m and a wall thickness of 1 cm - this is quite enough to heat a bathhouse or other utility room.

Used wheels from trucks

Note! Wheels from passenger cars will not fit - they have too small a radius.

Fire safety rules for arranging homemade stoves

The furnace from automobile disks heats mainly infrared radiation. To convert this stream to warm air, the stove must be shielded: surrounded by sheathing of steel sheets installed at a distance of 7-10 cm from the heater and with the same gap from the floor.

Safety rules for the operation of metal furnaces:

• Must be placed on the floor reinforced concrete slab or a steel sheet so that the refractory structure extends beyond the contours of the furnace at least 60 cm in each direction - this will protect against fire in case of accidental loss of coals from the furnace.
• The metal stove and chimney must not come into contact with flammable materials. Use insulating pads if necessary.
• Before kindling, always check for draft in the channels. If it is not there, you need to heat the chimney with a small amount of burnt firewood or clean the passages and the ash pan.
• Do not use liquid fire starters as they may cause fire to escape from the firebox opening.

Advice! If possible, install the stove in the bath so that the firebox goes to the dressing room. This arrangement has a lot of advantages: it is more convenient to heat, in windy weather the smoke will not get into the steam room and the dressing room will get some of the heat.

How to make a stove from disks for a bath with your own hands

First of all, the discs need to be prepared: cleaned of debris, rust or paint residue with sandpaper. After that, you can proceed to the manufacture of the structure, observing the stages of work in the specified order.

Water tank

To equip the upper chamber of the future stove, two rims are needed. Water will be heated in this tank, so it must be airtight. To do this, for 2 disks, the central plates for fasteners are cut out with a grinder, leaving only the rims. They are stacked on top of each other and welded together.

The top of the tank is closed metal lid or moving shutter. For safety reasons, you can combine these two options and tightly weld a larger segment of the cover, making only a small hole sliding or folding, through which water will be poured into the tank. A metal plate cut from a sheet is welded to the bottom of the chamber.

The device of the upper part of the stove

After welding work, in the upper part and at the bottom of the tank, holes are cut along the diameter of the chimney pipe. It will pass through the entire tank, should be tightly blocked by the walls and go out through the bottom. A thin tube is installed at the bottom of the tank at an angle to the floor and closed with a tap to drain hot water.

Note! The tank must be checked for leaks. Fill it with water and carefully inspect the cracks for leaks, Special attention giving the joints between the walls of the tank and the slots for the pipes. If defects are found, they must be eliminated by welding, but only after removing the water and drying the tank.

Arrangement of the heater and the upper part of the firebox

From the two remaining rims, you need to make a heater and a firebox cover. From one core is cut out, the second remains intact. The blanks are placed one on top of the other, and sewn together by welding so that the hub of the whole disk is in the middle (it will act as a lattice). From above, the container remains open - stones are poured here. The lower part of the cylinder will serve as the upper part of the firebox.

Best for arranging a stove natural stones rounded, which are used in saunas and baths - diabase, basalt, peridotite. But they are quite expensive. Therefore, you can look for material for the heater near the nearest reservoir - these stones have been well hardened by moisture and the sun. The best option- dark-colored rocks with a non-layered structure.

The best stones for a heater

Note! The stones in the stove, although slowly, are destroyed under the influence of high temperatures. And this makes it difficult for smoke to pass. Therefore, periodically the contents of the heater should be sorted out and replaced.

Foundation and brickwork

It is recommended to install the stove for a bath from rims on a solid and fire-resistant foundation. It can be built from reinforced concrete screed, and clad the upper surface with fire-resistant bricks.

When the base dries, you can proceed to the bottom of the furnace. For a stove with masonry 62 * 62 cm, you will need 60 pieces of red heat-resistant bricks. They are fastened with clay diluted with water and laid in a square. Do not forget to provide a cavity for the blower and a hole for the door. Attach the grate to the top of the masonry.

Stove assembly

All parts of the structure are assembled in series. The metal part is connected to the brick one, the firebox and the blower are closed with doors cut from a metal sheet.

Scheme of the stove-heater for a bath from rims

On a note! For comfortable use, it is desirable to equip the door with a handle from one large bolt. And so that firewood or coals do not accidentally fall out - also with a latch from a narrow plate of metal and a small loop.

Further, the second section of the pipe is welded to the central hole of the hub located between the firebox and the heater and sewn to the upper part of the chimney through the water tank. Stones are placed in the heater: below - large and medium, above - small.

To strengthen the structure, metal channels are welded to the rim of the heater and the water tank, which are installed at a slight angle to the upper part of the body. The pipe is discharged into a chimney lined with refractory bricks and equipped with a damper.

Such a stove will heat the steam room and the water in the tank in just an hour.

Stove from disks for heating utility rooms

The stove made of discs for a bath differs from other heating structures in that it has a special water tank and a brick base. If you only need space heating (for example, a small country house or garage), the design will be much simpler. For the base of such a stove, you can install several refractory bricks or a section from old radiators, on which a sheet of metal 5-8 mm thick is installed.

The most simple design homemade stove from wheel disks is done like this:

1. With the help of a grinder, the central part is cut out from three of the four disks.
2. Two disks are welded together. In the lower one, the bottom is closed with a round plate cut from a steel sheet, or it is immediately welded to a metal base.

Blank for the lower chamber

1. A small square hole is cut on the side surface of the grinder, and a door is made from the resulting piece of metal. It can be attached to the body with welded bolts and nuts, equipped with an iron handle and a latch. This part of the body will simultaneously serve as an ash pan and blower - to increase traction, it is enough to slightly open the door of the lower chamber.

1. The two remaining disks are also welded together so that the whole disk with the uncut core is at the bottom - firewood will be laid here. A hole is also cut out on the side of the firebox and a door is mounted.
2. The top of the stove is closed with a plate in which round hole under the chimney.
3. All parts of the body are connected by welding, a pipe with a valve at the top is lowered into the upper hole and welded.
4. The finished oven can be painted with heat-resistant enamel.

Finished oven for heating

Important! Seams - weakness any oven from rims. They must be welded with the utmost care, otherwise the smoke will enter the room through the cracks, instead of going completely into the chimney. If the seams become thinner and burn out during the operation of the stove, the cracks can be covered with clay and sprinkled with dry sand.

Video: making a homemade stove from car rims

As you can see, you can make a do-it-yourself oven from car rims to heat any small area. The only difficulty here may be the lack of a welding machine or skills to work with it. But this problem can be easily solved by inviting a professional master with the necessary equipment.

On cold winter days, it is pleasant to remember summer gatherings in nature: near a cauldron or by a fire with barbecue. And if kebabs can be cooked in winter thanks to the barbecue, then the situation is different with a cauldron. You can't do without a special oven. In addition, it will serve to heat a small room.

In order to make a convenient and practical oven for a cauldron with your own hands, it is enough to find a pair of old rims. How exactly to do this is described in detail in this article.

Why rims are the right choice for making a furnace body

There are many materials and improvised means from which you can make a stove with your own hands.

Often used for this purpose metal barrel, but the disadvantage of this design is that its not very thick walls can burn out from a strong flame. A more reliable and durable option is a stove made of a steel sheet of sufficient thickness, but the price, accordingly, will be rather big.

The best option is an oven from car rims, which has many benefits :

• availability of necessary materials;
• strength and durability, due to the thickness of the steel from which the discs are made;
• resistance to frequent and prolonged exposure to high temperatures and open flame;
• fast heating regardless of the type of fuel;
• the ability to choose the most convenient design dimensions, due to the variety of disc sizes;
• high heat transfer during space heating.

TO pluses wheeled ovens can be attributed to ease of manufacture. The main tools, without which you can not do in this business - welding machine And Bulgarian.

In the center of the design of the furnace for the cauldron two steel wheels.

How to make a stove from rims with your own hands:

So, after spending a couple of hours, you can find a convenient and practical stove for a cauldron. In addition, due to its low weight and compactness, it is easy to transport, even in the trunk of a car.

Firewood is best for heating such a device, and the draft inside can be adjusted using the fuel chamber door.

In the same way, using old rims, you can make a familiar to everyone potbelly stove. These stoves are used for heating small spaces, drying clothes or heating food.

To create a design, you can take large disks from a truck of the KrAZ-255B type.

The result is furnace equipment with a diameter of 50 cm, a height of 140 cm and a wall thickness of 1 cm. It can be used as a sauna stove.

Sections from old ones are suitable for the base of the structure. heating batteries, reinforced from the upper and lower sides with metal sheets 5-8 mm thick. In the final form, the base of the furnace will be obtained with dimensions of 0.6x0.6 m and a height of 0.4 m.

At the base of the structure is a combustion chamber with a door. Before installing the disk enclosure, a hole must be cut in the top sheet of the base.

1. 1. Install two rims on top of each other and weld around the entire perimeter to each other. Weld the lower part of the resulting body to the base.

1. 2. Cut a hole in the lower disk, into which a side pipe with a diameter of 0.2-0.3 m can be welded. Later, stones for the steam room can be laid here. If the stove is not used as bathing equipment, then the pipe will act as a firebox. Then the base is made from a single sheet and the mounting panel is sealed.

1. 3. From the upper disk, along the contour of the bolt holes, cut and pull out a circle. Make a cover from a sheet of steel 4-5 mm thick, prepare a hole for the chimney in it and weld it to the rim of the upper wheel.

4. Weld a chimney about 10 cm in diameter into the prepared hole.

At the end of the work, it will be useful to cover the furnace with refractory paint. To do this, it must be cleaned of residues old paint, after calcining the oven on fire and cleaning everything unnecessary. Only after everything has completely cooled down, you can apply a layer of black heat-resistant enamel.

You can explore another version of the stove from rims for a bath here.

Brazier using old wheels has a mass benefits, starting with the ease and convenience of carrying, ending with the ability to maintain required temperature inside due to the free access of air.

Such a brazier is convenient for cooking barbecue due to optimal height. It is easily transported from place to place, cleans well, and at the same time has high level reliability and durability. The option of a portable brazier made of steel sheets, as well as a folding brazier, we considered earlier.

Already thought many execution options homemade barbecues from wheels. Consider the simplest of them, the manufacture of which will require a minimum of materials and effort. For its device, it is enough to seal the lower opening of the disk steel sheet or other material such as ceramic tiles.

But, despite all the advantages, this type of barbecue has some disadvantages:

• Low location of the plane for cooking.
• If you install such a device directly on the ground, there will not be enough thrust to maintain the flame, which may cause it to go out.
• Small volume of the combustion chamber.

In terms of ease of use, such a design is equated to a conventional camping brick skewer stand. For infrequent use, such a model is suitable, but to make a more reliable and convenient brazier, you need to work a little more.

For such a brazier, you will need two rims and a small set of tools and materials:

• welding machine with electrodes;
• Bulgarian;
• meter profile pipe;
• fasteners in the form of bolts and nuts;
• wire;
• mask and gloves for personal protection.

There is nothing difficult in creating a brazier from two rims. Step by step it looks like this:

For accurate execution at the beginning of work, it is necessary to outline correct location doors on the side surface of the wheeled oven. It should be located a few centimeters above the bottom. A weld will pass through the middle of the rectangle, which is the door. Having finished marking, we proceed to cutting a hole for the door, after which we process the edges of the cutout.

Using bolts on one of the sides of the rectangle, make hinges for easy opening and closing of the door. Weld nuts to the door itself, which will pounce on the bolts installed in the housing.

The final touch of this stage will be the creation of a handle for the door from another bolt. To do this, it is welded a few centimeters from the edge on the side opposite from the hinges.

An important stage in the work is the manufacture of barbecue legs. The most convenient device for cooking is a device with legs of 60-80 cm, but everyone chooses the most suitable sizes for himself. To create steps, a profile pipe is suitable, from which 3 equal segments of a certain length are cut. Then they are welded to the furnace body at an equal distance from each other.

To maintain the same angle of inclination of all legs, it is recommended to install them with an emphasis on the side and partition. Compliance with these conditions will provide the structure with high stability on any surface.

At the final stage, handles are made for convenient movement of the barbecue. The most convenient location is in the middle of the structure on the sides of the door. Having outlined the edges of the handles, weld nuts to the body, into which to thread the handles bent from 8 mm thick wire.

An important nuance in the creation wheeled brazier- the bottom of the furnace should not be welded with metal, because this will interfere with the creation of good traction. To optimize the work, the bottom can be covered metal mesh or create a grate of thick wire, constructing a kind of grate.

That's it, ready brazier from rim with your own hands. If desired, you can improve its appearance. To do this, the metal must be well calcined so that all the remnants of paint, gasoline and oil burn out. After that, you can start sanding the body, and at the end paint it with black heat-resistant paint.

In the cold season, it is necessary to heat not only living rooms, but also a number of auxiliary outbuildings: greenhouses, garages, workshops, etc. It is too expensive to use gas or electricity for heating utility rooms. Alternative option there will be an installation of a metal potbelly stove.

Collapse

It can be heated not only with high-quality solid fuel, but also wood waste, rotten dry wood, etc. It is not at all difficult to build such a device with your own hands, but if you refuse to buy expensive metal-roll, and use old rims, it will be inexpensive. They are made from thick-walled heat-resistant material and are excellent for such purposes.

Design features

When making a furnace from car disks, one feature must be taken into account. According to the standards for the construction of solid fuel flame appliances, the distance between the bottom of the combustion chamber and the grate, i.e. from the place of laying fuel to the first barrier to exit flue gases in the vertical direction (for example, the arch of the furnace section) should be at least 45-50 cm. This is if it is supposed to load a conditioned type of fuel into the potbelly stove. When heating with raw wood or wood waste, the indicated size should be increased to 65-80 cm.

This is explained by the fact that solid fuel during combustion, it emits pyrolysis gas, which flies out through a direct chimney into the atmosphere, taking with it a significant proportion of heat. When the pyrolysis gases come into contact with a less hot surface, they cool down, before they have time to separate and burn out, and soot falls out. With further operation of such a furnace, the roof of the furnace and the inner surface will be covered with a dense layer of soot, which will not only reduce the efficiency of the device, but also increase the risk of fire.

Schematic view of a potbelly stove made of rims

Do-it-yourself potbelly stove made of rims is more often fired with waste fuel, and the optimal scheme of the furnace from such a range of material does not allow creating a high furnace department. Then, not standard grates are used, but a special design is made consisting of:

• from sheet steel with a thickness of 6 mm;
• reinforcement rods with a diameter of 12-14 mm.

A non-standard grate is inserted into the device with a small gap (5-8 mm), which is necessary due to the difference in the temperature coefficient of linear expansion of materials.

This version of the grate system also solves the problem of cleaning the furnace from ash. As an ash pan in a disc oven, you can use tin can with a diameter of 15-20 cm. And in order for the combustion process to have enough air, the chimney must be at least 100 mm in diameter and at least 2 m high.

In the horizontal model of the disc stove, no grate is installed, the fuel burns directly on the hearth. To regulate the air flow in the blower, a damper is installed.

Advantages and disadvantages

The advantages of using an oven from car rims include:

• Low cost. The construction of the heating device does not require large investments Money, since its most material-intensive part is made from ownerless rims.
• Durability and sufficiently long service life. In the production of car rims, thick steel is used, which has high strength, so such a home-made unit will faithfully serve more than one heating season.
• High thermal stability. Given the peculiarity of the steel alloy from which it is used for the manufacture of car rims, the device is able to withstand the effects of frequent and prolonged heating to high temperatures.
• Heating speed. An appliance of this design can quickly heat up to desired temperature regardless of what type of fuel will be loaded into it.
• No size restrictions. For the construction of the furnace, you can choose disks of a more suitable size and raise the structure up not only from two, but also from three, four or more disks.
• High heat dissipation. efficiency homemade stove from automobile disks reaches 80 - 85%.

However, potbelly stoves from car rims, in fact, like other metal stoves:

• unable to accumulate and retain heat on for a long time. The metal case quickly gives off heat and cools down, so such a potbelly stove will heat the building only while firewood or another type of fuel is burning in it;
• require the installation of a high chimney. To ensure a sufficient level of draft, it is necessary to build a chimney with a height of at least 2 m;
• must be regularly cleaned of all departments, and especially carefully the chimney. A large diameter chimney must be cleaned at least once every 1.5-2 months. If its diameter is small, then this procedure should be carried out at intervals of 1 time per week.

How to make a potbelly stove from rims?

A potbelly stove made of rims will be portable, which is very convenient, since you can use this design as needed in not only the garage, but also in other rooms. It can be installed both horizontally and vertical position. Both models have high heat transfer, and differ from each other only in the presence of grates and the location of the chimney.

materials

For the construction of a potbelly stove, it is desirable to use parts from the wheels of cars or light trucks. The disks from a heavy-tonnage truck are too massive, a potbelly stove from them will turn out to be bulky and heavy. In such a design, it will be difficult to ensure the tightness of the joints when joining individual elements.

In addition to the disks themselves, for assembling the oven with your own hands, you will also need several additional materials:

• reinforcement rods with a diameter of 20 - 24 mm;
• steel corner;
• sheet metal 4-5 mm thick;
• heat resistant paint;
• several bolts and nuts;
• pipe with a diameter of 100 - 150 mm and a wall thickness of at least 5 mm.

Tools

The set of tools necessary for the construction of a potbelly stove from car rims should consist of:

• welding unit and electrodes;
• grinders (angle grinders) with a set of cleaning and cutting discs;
• drills;
• gas cutter;
• sandpaper;
• brushes;
• sledgehammers;
• hammer;
• measuring and marking devices: chalk or marker, tape measure and ruler

To protect the surface of the body and eyes from harmful radiation from the welding arc, sparks and splashes, it is necessary to work in special uniforms, complete with a canvas suit and gloves, closed shoes, a headgear under the shield, a welder's shield and goggles.

Step-by-step instruction

At self-manufacturing disk ovens must be observed next sequence actions:

• cut out the central part of all four discs with a grinder along with the hubs;

  

• make two round plates from sheet steel, the diameter of which must correspond to the size of the disks;
• cut a small square opening for the blower on the side surface, and make a door from the separated part of the metal. It is put on bolts welded to the body and secured with nuts. For ease of use, the door is equipped with a metal handle and a latch;

  

• weld the walls of the two discs together. Close the bottom of the lower disk with a metal plate and weld legs from metal corner or fittings;

  

• weld the two remaining disks together and close the upper part with a circle of sheet steel;

  

• cut an opening for the firebox on the lower disk of this part of the furnace and install a door, similar to a blower door;

  

  

• connect all parts of the body into a single structure;
• install grate. For these purposes, inside the combustion chamber, weld the guides from the corner and put on it a pre-welded structure made of sheet steel along the edges and reinforcement in the middle. The reinforcement bars must be positioned so that the distance between them does not exceed 2 cm, otherwise small firewood will fall through;

  

  

• cut a round hole for the chimney on the upper surface of the device;

  

• if desired, you can organize a chimney on the side so that you can use the top of the potbelly stove as hob, it will look like this:

In the manufacture of such a potbelly stove, it is necessary to take into account that special compound alloy steel wheels is not standardized for welding. Therefore, when connecting disks, you must follow the following rules:

• only two mating parts can be welded at a time; it is forbidden to assemble the entire device at once;
• after a seam has been formed, parts with welded edges must be left alone for about 3 to 5 minutes, so that the residual internal stress is absorbed;
• the surface of the weld must be free of any visible defects: cracks, splashes, shells or bubbles.

trial firebox

The finished furnace must stand for a day for complete absorption of the same residual stresses. After that, it must be subjected to a test furnace with a full laying of fuel for 3 hours. At the same time, its furnace and blower doors must be open.

During the first test firing, the internal surfaces of the device are also annealed. If minor defects are found welding seams, but no more than two per seam, they are removed a day after the oven has cooled down. Then you should repeat the run of the device with annealing.

Conclusion

A potbelly stove made of car rims, although it is constructed from used parts, is very solid in design. Thick strong steel served its time in vehicles and received a certain amount of deformation, but as a material for a reliable body heater may not last more than one year. The most important thing is that such a stove will be safe and effective in heating the room, and the solution to the issue of its design appearance depends on the imagination of the owner.
