Do-it-yourself gasoline burner: manufacturing process for soldering and a homemade tourist burner according to drawings

Advantages and disadvantages of a gasoline burner

Among the main advantages of BG are the following:

1. Proper functioning of the burner at an altitude of 3-4 thousand above sea level.
2. The burner can operate normally even at minus 40 degrees Celsius.
3. Fuel such as gasoline costs much less, especially when compared with gas.
4. Light weight burner and ease of use.
5. You can take the burner anywhere, for example, fishing, hunting or just on a hike.
6. This device is convenient to use during installation work.
7. The high temperature at the outlet allows you to work with various types of metals and alloys.
8. You can use other fuel: kerosene, alcohol or diesel fuel.

But a gasoline burner also has disadvantages:

1. High fire hazard, especially during fuel filling.
2. Most often, the fuel torch is uneven.
3. Soot may appear during operation.
4. It is important to use pure high-octane gasoline, otherwise the throttle hole will quickly become clogged.

What is the tool for?

A blowtorch is a type of heating tool that creates a high-temperature flame characterized by directional action. This tool is especially popular among home craftsmen, and it is used to perform a number of the following actions:

1. Heating of parts for the purpose of soldering them, which occurs due to melting of solder
2. Compounding materials whose melting point does not exceed 900-1100 degrees
3. Heating the paint coating, which is carried out for the purpose of removing it
4. Warming water pipes when the coolant freezes in them
5. Used for cooking purposes, but in this case you cannot do without the use of auxiliary stands
6. Carrying out construction manipulations - when laying roofing material, it is melted in order to secure the connection
7. Firing of threaded connections to make screwing and unscrewing easier
8. Lighting fires, fireplaces and bonfires

Do-it-yourself gasoline torch for soldering

First of all, it is important to say that gasoline burners made independently are no worse than factory ones. BG made by hand is just as productive and safe.

It is important to note that the temperature at the flame can exceed 1000 °C. Therefore, such a burner will easily melt refractory solders, perform heat treatment of small tools, melt various metals and even glass.

You will need:

• Frame.
• Fittings.
• Cotton wool (cotton and basalt).
• 2 valves for regulating the supply of the air-fuel mixture.
• Silicone pipes.
• Flexible plastic ties.
• Copper tube.
• Emphasis.
• Sealed metal can.
• O-rings.
• Pen.
• Rubber bulb.
• Filler.

The process of creating a gasoline burner with a compressor with your own hands:

1. The body is created on a lathe; the workpiece can be a steel alloy of any grade. One end of the tube should be closed with a stopper, and the other will be open. It is necessary to drill a hole in the plug 0.2 mm larger than the supply tube. Then the housing will move successfully along the tube, while the tightness will be maintained.
2. Several pieces of steel mesh and basalt wool should be inserted into the housing. This is done so that if the flame breaks out, the fire does not reach the fuel container.
3. After this, it is important to make a sleeve with a hook and a resting element. It can be made from a sheet of steel 2-3 millimeters thick.
4. The handle can be cut from ash or oak.
5. Two through holes are drilled carefully. In this case, the projections of the drilled channels must be equidistant. Then the handle is sanded with sandpaper, then you need to apply 2-3 layers of colorless varnish.
6. After this, the copper tubes are passed through the handle, after which they are sealed with refractory solder. Next, holes are drilled into them using a 0.3 mm drill.
7. At the outlet of the tubes from the handles, 2 valves are installed, then there is a transition to silicone hoses. They are connected through fittings to a metal can, it is important to embed one fitting in the upper part of the can, and the second in the lower part, this is done so that concentrated gasoline vapors flow through one tube, and less saturated ones through the second. Don't forget to install O-rings on the fittings to prevent the mixture from leaking. The bottom of the jar is tightly packed with cotton wool. A bulb for pumping air is also connected to it.
8. This completes the assembly, now you can fill the cotton wool with gasoline, seal the jar hermetically and test the device. To do this, air is pumped into the system with a blower, and then the combustible mixture supply screws are opened and set on fire.

Even such homemade gasoline burners will function properly, especially if you made the device according to our instructions.

Remember! If you do not have knowledge of the operation of burners and experience in using burners of this type, then it is better to buy a production version of the device.

Below you can see a photo of a DIY gasoline burner.

Blower device

Inflate with oxygen. Either with pure oxygen (usually from an oxygen cylinder, there is an alternative - an oxygen concentrator, which lampworkers use, but for some reason jewelers do not use, but I think a concentrator will do), or with air (oxygen is one of the components of air). There are different devices for blowing: - bellows (frog)

A device such as a foot pump for inflating tires for a bicycle. Or for inflating an air mattress. There are craftsmen who have and are adapting the above-mentioned devices to burners; some improvements are needed, but the essence is the same. There are ready-made leather ones with a receiver - optimal. A torch with bellows for soldering is ideal! in this case, you can always adjust the composition of the mixture with your foot (correctly - “quality of the mixture”) - pump more intensely - more oxygen, in the case of other methods of blowing - as the flame was set before soldering - this is what it will be along the way, you can only adjust it by “closer” - the burner is further away from the product.” At the exit, it all comes down to adjusting the temperature of the flame and its properties (oxidation-reduction). This type of blowing occurs in both gasoline and gas burners.

A certain thing runs on electricity. Everyone has seen this - the thing that blows bubbles in an aquarium with fish is it, the compressor. With skill, you can blow up the burner with an aquarium compressor (put a couple in parallel), or you can take a compressor from an old refrigerator (that’s how we lived under the scoop). Naturally, you can buy it now, but homemade compressors are still in use. This type of blowing occurs in both gasoline and gas burners.

-injection

Jewelry burners only happen on gas burners, but in life it also happens on gasoline burners - a typical example is a primus stove, if anyone has seen it. The burner inflates itself due to the speed of gas flow and holes for air suction around the nozzle. In practice, the terrible term “injection” boils down to the following essence: if a train is rushing quickly past you, do you feel a draft? - This is due to the fact that a rapidly moving body carries air particles with it. And in an injection burner it’s the same thing - a stream of gas under pressure escapes from the nozzle, there are holes around the nozzle, air is sucked through them and the flame is blown. These small burners with piezo ignition, which many people use here, are of the injection type. Lampwork HodHead is a typical injection burner.

Preventing clogging

During use, the channels or nozzles for supplying the combustible mixture may become clogged.

To prevent this from happening, it is important to follow these recommendations:

• Use gasoline with the lowest octane number.
• Each use of the burner must be completed by thoroughly cleaning the device.
• Once a month, add high-quality injector additives to gasoline.
• Systematically clean the system with carburetor cleaner. Such products fight very well against various deposits in fuel channels and jets.

What are blowtorches made of?

Mostly steel materials are used to make a blowtorch. The nozzle of a blowtorch is subject to high temperature loads, so mainly reliable materials are used for its manufacture - cast iron, welded steel, and brass.

The lamp handle is made of steel, while more expensive models have a plastic or rubber coating. The regulator is made of plastic, for which a fire-resistant type of plastic is used. The presence of plastic or rubber on the handle makes it easier to operate the tool, so when choosing, it is recommended to pay special attention to this point.

This is interesting! If you plan to rarely use a blowtorch, then it makes no sense to choose the most expensive and sophisticated models, since their potential will not be used to the fullest.

Buy or make a burner yourself

Buying a gasoline burner in a store is the easiest option. Understanding which model is best for you is quite a difficult task, because everything depends on the design features.

Sometimes burners are heavy, so you won’t be able to take them with you, especially if you don’t have a vehicle.

Factory-made burners are extremely expensive, and for their stable operation you need to buy only high-quality fuel.

• Creating a BG yourself has certain advantages.
• Firstly, you can refuel such burners with the most affordable fuel, and secondly, you can create a drawing of a gasoline burner and make exactly the device you wanted.
• And thirdly, you can install accessible consumables that you can quickly change while using the burners.

We are confident that this article will help you create a homemade gasoline burner. We wish you good luck!

Features of jewelry

Gasoline burners for repairing and making jewelry are separate from other devices. They are used for smelting precious metals. The devices are characterized by their miniature size and large heating area . Currently, most factories use high-precision laser systems, which improve the quality of the finished product.

Despite the fact that jewelry burners are practically not produced, their use is relevant for jewelry repair. That is why modern goldsmiths very often ask the question: “How to make jewelry burners with your own hands?” On specialized forums you can always find descriptions and drawings of high-quality models.

What sizes are blowtorches available?

When choosing a blowtorch, it is important to consider the size and weight of the tool. The size and weight of the blowtorch depends on such an important parameter as the capacity of the fuel tank. The larger its volume, the correspondingly higher the weight and dimensions. The need to use tools of different sizes depends on the tasks for which the device is used.

There are the following types of blowtorches based on the volume of the fuel tank:

1. Two-liter - the dimensions of such devices are 290x160x275 mm
2. 3.5 liter devices weigh from 1.5 to 2.5 kg
3. The minimum fuel tank volume of the devices in question is 0.5 liters

The larger the tank volume, the better, however, such devices have their drawbacks:

• Heavy weight, which negatively affects the operation of the tool. It is more difficult to operate such devices
• Large dimensions, which complicates not only operation, but also storage and transportation of the device
• A large tank requires high refueling costs

It is necessary to buy a tool taking into account the tasks that are planned to be performed using the equipment in question.
