Useful homemade chainsaws, what options?

Craftsmen do not always use a chainsaw for its intended purpose; it usually serves as a powerful drive in various mechanisms.
The ingenuity of our craftsmen has given rise to numerous and very diverse homemade chainsaws, surprising in their originality. The advantage of a chainsaw as a drive is its compactness, low weight and high power. Any craftsman who is capable of turning a part can perform metalwork, use a grinder and a welding machine, and can make interesting designs based on a chainsaw.

In order for a device driven by a chainsaw to function as it should, accuracy in the dimensions of parts and care during assembly are required. So, knowledge of the basics of drawing and designing mechanisms will be useful in this matter.

Technology on the verge of fantasy

For a long time in the Soviet Union there was a story about a prisoner who was able to fly out of the zone in a homemade helicopter made from a chainsaw . In fact, this is just a beautiful legend, although it also has real scientific developments.

In 1971, a group of students from the Moscow Aviation Institute presented a new unusual development to the academic council. It was a flying single-seat platform with eight engines from the Druzhba chainsaw , synchronized in one block. Prototypes of these developments have been repeatedly shown at various exhibitions. Despite this, such models were never produced commercially.

The dream of heaven for those who like to construct something from chainsaws remains a dream for now. However, attempts to make a backpack single-seat helicopter using engines from the Ural or Druzhba do not stop.

From an old chainsaw you can make a cool mini moped for riding. The design of such a homemade moped is extremely simple and even a schoolchild can make it.

As an example, you can use this compact mini bike, made by one of the craftsmen; the photo shows its design.

The frame of the moped is made of a profile pipe; fastenings are made on the frame, where the motor from the Druzhba chainsaw is mounted. The engine gearbox is turned in the opposite direction, this made it possible to change the direction of rotation of the drive sprocket and, accordingly, the rear wheel of the moped. The drive sprocket of the gearbox and the driven sprocket of the rear wheel are equipped with a chain from a moped.

The wheels are taken from a regular construction trolley.

The steering wheel is made from a handle from the same chainsaw, the front fork is welded from pipes. The steering wheel has a throttle handle.

The fender liners are curved from sheet metal.

The fuel tank is taken from a chainsaw.

The result is a simple mini moped that can be ridden by both children and adults. A mini bike with a chainsaw engine can accelerate to 50 - 60 km/h.

The chainsaw is very popular among home craftsmen because it is a universal drive for original homemade designs.

Light weight and solid power combined with compact dimensions allow this “lumberjack’s dream” to be combined with an ice auger and a bicycle, a sawmill and a winch.

Interesting homemade products from a chainsaw can be made by anyone who confidently works with a welding machine, an angle grinder, and, if necessary, can even use a lathe.

In this case, knowledge of the basics of design and drawing will be very useful, since the accuracy of all dimensions and quality of assembly are the main conditions for the normal functioning of a unit driven by a chainsaw.

Without going into technical details, we will consider the most interesting designs using it.

What homemade chainsaw products have already been invented?

The first use of a chainsaw from the point of view of many developers is to cut logs into beams with its help. But, if you hold the chainsaw suspended manually, the cutting accuracy suffers, especially when the beam is four to six meters long. To prevent the cut from moving away from the desired line, we came up with the idea of rigidly securing the chainsaw in a frame that moves along guides.

In such a sawmill, the log lies motionless, and the carriage with the chainsaw is located at the required height, depending on the desired thickness of the beam, and is fixed with four screws.

Thanks to the precise movement of the frame, a smooth and neat cut is obtained. You can cut boards in the same way, but due to the large thickness of the cutting chain you will end up with a lot of waste.

Chainsaw-winter transport

They managed to use a chainsaw as an engine for a homemade snowmobile. Here the design is much more complex than a sawmill. In this case, in addition to manufacturing the snowmobile frame, you will need to make a suspension with shock absorbers, and connect the gas and clutch controls to the steering wheel.

In addition, you will need to find the drawings (or design it yourself) according to which the snowmobile track will be made, and think about the transmission of torque from the chainsaw to the track. Such a snowmobile is equipped with a centrifugal clutch with a chain and a poly-V-belt (after all, the chainsaw does not have its own transmission). In order to increase traction, a gear with a diameter larger than the chainsaw drive sprocket (the so-called “traction gear”) is installed on the track drive shaft.

For the steering mechanism, as a rule, they take the steering wheel from a scooter and bicycle and easily modify it so that it turns the snowmobile skis. Such transport requires an engine with a power of at least five horsepower, so if you are making a snowmobile, then use a Ural chainsaw.

If we consider transport for the winter, then the design of a snowmobile is much simpler. In them, a large screw is attached directly to the shaft of the chainsaw mounted at the back, which is the propeller. True, the low power of the chainsaw limits the maneuverability of such sleds on ice on a river or a compacted road. For racing on snowy fields, you need an engine of at least 12 horsepower. The same restrictions do not allow you to add a backpack helicopter to homemade chainsaws. Unless you use two engines and the master manages to make them work in harmony.

Homemade options

The first thing that comes to mind when you think about what can be done with a chainsaw is its use as a sawmill. Many developers had to split logs onto beams with this tool.

Holding the saw suspended in your hands, it is very difficult to control the accuracy of the entire length of the cut. Therefore, with a log length of three or four meters, it moves far away from the intended line. This problem can be solved quite simply. To do this, the chainsaw is rigidly fixed to a frame, which moves along a guide profile.

In this case, the log lies motionless and is neatly sawn along its entire length without wobbling or oblique seams. If you equip such a mobile carriage with four lifting screws, you can accurately set the thickness of the sawn timber.

A sawmill using a chainsaw will also work on boards without problems, only in this case there will be too much waste, since its cutting chain is several times thicker than the saw of a band sawmill.

Snowmobile

A lightweight homemade snowmobile made from a chainsaw is more complex in design than a sawmill, since here you need to move the gas and clutch to the steering wheel, and also take care of the shock-absorbing suspension of the supporting frame.

In addition, you need to develop it yourself or use ready-made drawings of the caterpillar and correctly transfer torque of sufficient power to it from the motor. Since the chainsaw does not have its own transmission, the clutch on such a snowmobile is fitted with a centrifugal clutch with a serpentine belt and chain.

To increase traction, a “traction” gear is placed on the caterpillar drive shaft, the diameter of which is larger than the size of the chainsaw drive sprocket.

There are usually no problems with the steering mechanism, since it is taken from a regular bicycle or scooter and modified so that the central axis moves the rods that turn the skis. The snowmobile engine power must be at least 5 horsepower, so it is better to use a Ural chainsaw for this purpose.

The winter line of homemade vehicles will be complemented by snowmobiles made from a chainsaw, which are structurally simpler than a snowmobile. The driving force is provided by a large diameter screw, which directly rotates the gasoline engine.

A significant limitation for the cross-country ability of such a machine is the low power of the chainsaw. Therefore, you can only move on them on a flat surface of compacted snow, ice of a frozen lake or river. To travel across the fields you will need an engine with a capacity of at least 12 horsepower.

Those home inventors who would like to make a backpack-type helicopter from a chainsaw should know the same thing. Such a machine will require not one, but at least two engines operating in a coordinated mode.

Moped

This vehicle is most often made for the sake of principle rather than practical use. The main driving force of its creator is the desire to test his strength as a mechanic and prove to others the original use of this cutting tool.

The basis for the design is usually my grandfather’s old Druzhba chainsaw and an equally ancient bicycle, with which you can carry out any experiments on converting the frame for mounting the drive.

Power is transmitted here through a gear pair using a bicycle chain, and the start of such a homemade product is reminiscent of preparing for cutting firewood.

Less common are more advanced models, the basis for which is a mountain bike equipped with reliable brakes and shock absorbers. This chainsaw moped is equipped with a gearbox with a gear ratio of 18:1 and a CVT transmission, which allows you to comfortably move on it at the speed of a regular bicycle.

boat motor

This option for using a chainsaw is quite simple, since the task here is to transfer torque from the saw motor to the propeller. A homemade outboard motor does not need to install a transmission. For it you will need to make a reliable adapter on a lathe from the saw drive gear to the propeller shaft. The propeller can be used from a standard outboard motor.

The photo shows an option in which there is a gearbox in front of the propeller that changes the angle of rotation of the shaft by 90 degrees. In simpler models, they do without it by mounting the engine on the boat so that the shaft is immersed in the water at a slight angle.

Motor cultivator

It is difficult to make a full-fledged walk-behind tractor from a chainsaw due to lack of power and traction. But many home craftsmen were able to build a lightweight motorized cultivator based on it.

The design of such a machine is very simple: the motor rotates a pair of gears and transmits increased traction force to one drive wheel.

snow blower

The chainsaw motor is no different from rotating the cutting chain or the auger mechanism of a snow blower. Here everything depends only on the design abilities of the creator and his ingenuity.

Using a Stihl chainsaw with a power of about 3 kW, you can easily build a good device for clearing an area of loose snow. To simplify the design, some craftsmen refuse to install wheels and use conventional sled runners.

The most important part, which determines how well a homemade snow blower will do its job, is the auger assembly. It is driven by a gear pair and a chain. The blades are made of thick cord rubber, and the intake device is made of galvanized steel sheet.

You can fit a plastic sewer pipe under the snow thrower by attaching it to the intake body.

The chainsaw asks for the sky

The most daring inventors have long been eyeing the possibility of using a chainsaw as an engine for an aircraft. However, this instrument is not strong enough to master airspace. Therefore, no one has yet succeeded in making a backpack helicopter out of one chainsaw.

Calculations have shown that this requires at least four chainsaws (total power from 20 hp) of a forced design, which would allow them to increase speed several times and work in a coordinated mode.

Motor drill

This device is useful not only when building a fence or foundation from screw piles, but also during winter fishing, when you have to drill dozens of holes in thick ice.

Since the ice auger operates at low speeds, to adapt the chainsaw motor, it is connected to the auger through a reduction worm gear.

Winch

A motor winch is a very useful device, because with its help you can not only easily pull out a stuck car, but also lift a heavy load to a height, pull a boat onto land or move a cut tree.

The power of such a homemade product depends on the power of the chainsaw used, and its pulling force can reach 1500 kg. Such a winch must be equipped with a sling belt, hooks and anchors for attachment to the ground, tree trunk or car.

Power station

The camping power station is assembled on the basis of Ural or Druzhba chainsaws. It consists of a frame, an engine with a gear reducer, a control panel, a generator and connecting electrical cables.

1 – chainsaw 2 – gearbox 3 – cord drive belt 4 – tension bar 5 – generator; 6 — control panel; 7 — clamps; 8 – supporting frame; 9 - saw tooth stop; 10 — nut for fastening the frame to the gearbox; 11 - drive pulley

A good owner will not throw anything away in vain, especially if we are talking about high-quality metal. If you understand the nuances of heat treatment of metal, you can make a solid forged knife from a chain that has served its life.

This thing looks no worse than the creations of Arab blacksmiths who forged swords from the legendary damask steel.

Homemade chainsaw - the engine is large

It cannot be said that such a design will be of much use, but many people make such a unique vehicle simply to test themselves and show others their skill as a designer and mechanic.

The basis is an old bicycle, which you wouldn’t mind, and the well-known Druzhba chainsaw. The transmission of force to the wheel is carried out using a bicycle chain and a gear pair.

Sometimes they take a mountain bike, and install a variator transmission and gearbox between the chainsaw and the wheel (to move slowly but confidently, you need a gear ratio of 18:1). This “advanced” model is equipped with shock absorbers and brakes.

Gasoline scooter

To create such a vehicle you will need:

saw motor;
chain;
bolts, nuts for fastenings;
switch and accelerator from a mountain bike model;
old scooter.

The bar part with the chain is removed from the saw, everything else remains and will be installed on the scooter platform. The clutch is unscrewed from the crankshaft. The motor power will be supplied by the bicycle chain through the sprockets. Let us immediately warn you that there will be two problems - it is impossible to stop the engine, and when starting it you will have to raise the rear wheel above the ground. We screw the sprockets onto the rear axle of the scooter.

We place the motor on the platform so that its sprocket is in line with the wheel group. Having drilled holes in the saw body and the scooter platform, we connect them with bolts.

Having adjusted the length of the chain, we pull it onto the stars. The accelerator mounted on the handle is connected by wires to the on and off wiring so that it is possible to keep the supply of motor energy under control.

The manufactured base elements are aligned in parallel, level, which is especially important to avoid creating free play. This is done on a concrete surface, foundation base or compacted earth. The frame is fixed with bolts or studs and welded to the foundation reinforcement.

Now the rail base is installed, fixed to the side fastenings.

The procedure can be seen in the video:

Motor cultivator made from a chainsaw

Many people have managed to make a simple motor cultivator out of a chainsaw, in which a pair of gears increases the traction force of the engine and transmits it to the drive wheel. You must understand that the insufficient power of the saw engine will not allow you to make a real walk-behind tractor in this way.

Resourceful craftsmen show their talents in designing snow removal equipment. There are known models based on the three-watt Calm chainsaw, which is installed, for simplicity of design, on sled runners. The main thing is to make a high-quality auger assembly and select a gear pair, and the chain saw engine doesn’t care what to rotate.

For such a snowblower, galvanized steel is used to make an intake device, blades are made from corded, thick rubber, and a regular sewer plastic pipe will serve as a snow thrower.

Summarize

Making equipment with your own hands from old equipment is quite an exciting activity. It's nice to give a second life to devices that have served their time. After practicing on Druzhba or Ural, you can begin to remake newer models from foreign companies. In any case, it will cost much less than purchasing specialized factory-made equipment. At the same time, the home master will receive a bonus and satisfaction from the work done.

Husqvarna saws are considered one of the best today, along with the Stihl brand.

We hope that today's article was useful to our dear reader. We will be glad if you share your experience in making various homemade products in the discussions below - this may help novice home craftsmen. There you can ask questions if they arose while reading. The Seti.guru editorial team will be happy to answer them. Write, share, ask. And finally, following the established good tradition, we suggest watching a short but very informative video on the topic of alterations to chainsaws.

Chainsaw based helicopter

Although many inventors are looking for ways to make a small single-seat helicopter based on a chainsaw, its power is still not enough to fly. As engineering calculations have shown, a mini-helicopter requires at least four high-powered chainsaws, working in concert and with an increased number of revolutions.

A motor drill made from a chainsaw will greatly facilitate the installation of a foundation on screw piles, installation of a fence or drilling holes for winter fishing. Just keep in mind that the chainsaw engine must be connected to the ice ax auger through a reduction gearbox (worm gear).

Other devices

You can easily and quickly make an angle grinder from a saw that can work autonomously and have high power. For such a transformation, you need to buy the necessary attachments at a building materials store that will help transform one tool into another. To reduce the likelihood of blade breakage, the saw can be equipped with a protective casing, and the number of revolutions can be reduced with a high-speed gearbox.

A good solution is to make a portable generator set from a saw. It will come in handy in a summer cottage where there is no electricity. A power of twelve volts will be enough to provide illumination as from a normal flashlight.

By connecting the inventor, you can convert the energy to 220 volts.

Among the useful homemade products you can add a motor to an inflatable boat, a motorcycle (you will need more than one saw for it), and a light aircraft.

Chainsaw winch

Using a chainsaw, it is easy to make a winch with a force of up to one and a half tons. Such a device will help lift a massive load to a height, remove a cut tree, pull a boat ashore or a stuck car onto the road.

A small gasoline power station is useful in the household. A generator, a Druzhba or Ural chainsaw is mounted on a durable frame and connected to the gearbox. A pulley is attached to the gearbox shaft, from which a cord belt transmits rotation to a generator, which will provide the household with electricity in the event of a power outage or absence.

So, although this instrument itself is familiar to everyone and its purpose seems unambiguous, craftsmen come up with many interesting designs. As you can see, homemade chainsaws are very diverse (some enthusiasts even manage to forge a knife from an old chain).

The talents of home craftsmen have led to the emergence of a large variety of equipment powered by a chainsaw.

Making a snow blower - algorithm of actions

The manufacture of the unit should begin by creating or studying existing drawings. This will allow you to prevent possible errors in advance and complete the work as quickly as possible.

The correct procedure is as follows:

First of all, you need to prepare the frame. The reliability of the machine depends on its quality, so you should choose reliable materials for its manufacture. First you need to take several identical pipes and weld them to each other

In this case, pay special attention to two longitudinal pipes, which not only serve as part of the frame, but also act as skids of the unit; The front parts of the pipes must be cut at an angle, and then the resulting holes must be welded to prevent snow from getting into them. If this is not done, melted snow inside the pipes will lead to corrosion.

At the same time, you won’t even notice it; Weld two transverse pipes to two longitudinal pipes. In this case, the latter should be located in the rear part of the structure, since the unit’s motor will be supported on them. The distance between the transverse pipes should be about 20 cm; Next, you need to remove the engine from the chainsaw. Instead of the standard motor drive sprocket, which serves to tension the chain, you need to install an ordinary small sprocket. It can be taken from an old Voskhod or Minsk motorcycle. The sprocket must be fixed motionless by welding it. However, before this the part will need to be centered; After manufacturing the frame, you need to move on to creating a working element - the auger of the unit. To do this, take a small diameter pipe or shaft, 80–85 cm long. These dimensions are needed for mounting the drive in front of the main part of the structure. Particular care should be taken in selecting suitable bearings; Next, take a metal sheet 2 mm thick and cut out 4 identical circles with a diameter of 30 cm in it. You need to cut holes in each circle with a diameter of 22–23 cm. Then each of the circles will need to be trimmed to make turns out of them; Then you need to determine the central part of the shaft and weld 2 metal plates, 13 cm long and 15 cm wide, to it. Place the sheets strictly parallel to each other. They will serve to throw snow to the sides when operating the snow blower; Weld screw strips to one side of the blades. Next, install the spacers on the shaft and weld the other ends of the screw bands to them. In this case, all 4 screw plates should be directed towards the center of the auger. The entire manufactured structure must fit into a 70-centimeter section of the shaft, since the drive will be installed on the rest of it; The next step is to move on to manufacturing the body. To do this, you need to take 2 round sides, the size of which should be 7 cm larger than the auger. After this, you will need to weld a metal sheet no more than 1 mm thick to the circumference of the sidewalls. As a result, you should end up with a semicircle of metal plates. Make holes in the central parts of the sidewalls and install the auger in them; Before attaching the auger, you need to install bearings on the shaft and press them securely. Remember that the auger must be centered. Use cages to secure the bearings; Next you need to assemble a snow disposal. For this you will need an aluminum pipe with a diameter of 15 and a length of 10 cm. You will also need a metal sheet from which you need to form a box. To install the snow drain, you need to make a hole in the back of the auger blades. A pipe is inserted into it and secured with ordinary bolts. Place and secure the box on top of the pipe; Then put a sprocket from a domestic motorcycle on the drive section of the shaft; At the last stage of manufacturing, you need to assemble the entire existing structure. To do this, the housing and auger must be installed and welded to the longitudinal pipes of the frames. Install the chainsaw engine on the transverse pipes so that the drive and driven sprockets are located strictly in the same plane; Install a chain on the drive and make a handle from leftover metal pipes. Don't forget to move the throttle control lever to the handle.

Upon completion of assembly, you need to test the unit. To do this, walk around the yard with him, removing freshly fallen snow, and then move on to removing the accumulated snow masses.

Why from Friendship

Let's name a number of arguments why it is worth using the Druzhba chainsaw for remodeling:

popularity - the chainsaw was very popular during the USSR, because There were simply no other saws, except perhaps the Ural.
cost - today on the secondary market the price, depending on the condition, varies from 1000 to 2000 rubles.
power - the saw belongs to the professional category, intended for felling trees, so it is well suited for such homemade products as a mower, helicopter, sawmill, all-terrain vehicle, motorized dog and others.

Choosing a chainsaw for a homemade snow blower

The power and performance of a snow blower directly depends on the engine you choose. This main element is removed from the chainsaw. The higher the power of the saw, the better. The engines in household models are two-stroke, power varies from 2 to 10 horsepower. For a homemade snow blower, 5 horsepower will be quite enough. Below we will look at the most popular brands of chainsaws that are often used for homemade snow blowers.

Chainsaw “Friendship”

This chainsaw was developed during the USSR, in 1950, after which it began to be produced en masse in the Soviet Union. Since then, the technical indicators and characteristics of the saw have become significantly outdated. The weight of the unit is 12 kg, in addition, the saw has large dimensions. Experienced owners say that the first saws, which were assembled in the first decade of the plant’s existence, still work properly.

However, chainsaws produced after 1990 are characterized by frequent defects, regular breakdowns, malfunctions and a short service life.

Gasoline saw “Ural”

Another representative of the domestic production of chainsaws. “Ural” tools can be called a kind of improvement on “Druzhba” saws. With the same weight, the Ural has more power from a two-stroke gasoline engine (5.5 horsepower) and smaller dimensions. In this regard, the performance of these devices is much higher.

German chainsaw “Stihl”

Imported sawing equipment is often much better in quality and performance. Foreign factories, such as the German concern Stihl, always try to produce technological innovations. Of course, this also affects the cost of the equipment. Shtil is one of the most popular companies among the Russian population because it has high power, excellent quality, long service life and a relatively low price.

What do you need for work?

To make homemade products from a Friendship chainsaw with your own hands, you need a beginner’s tool kit, a desire and an idea. The main tools needed for work are an angle grinder and a welding machine. You already have a desire, otherwise you would not be on this page. The very idea for converting the Druzhba chainsaw into any unit can be found in this article.

In the article we offer only an idea, without step-by-step instructions for action. Otherwise the article would have been ten times longer. If after reading you still have questions and you need detailed instructions, then leave your wishes in the comments to the article and we will write a step-by-step guide for converting a chainsaw into a specific unit that will collect the most wishes.

Features of rework and preparation of materials

Almost any modern snow blower has a fairly simple design. In fact, anyone can assemble such a unit with their own hands. All that is required for this is the availability of the necessary materials.

The only problem that homemade enthusiasts may encounter is the lack of an engine. True, the dilemma is easily solved if you make a snow blower from a Ural chainsaw. In addition to a working motor, you will also need to prepare other necessary materials:

Aluminum and steel pipes;
Bearings and shaft;
Metal sheets;
Welding machine;
Tools from the garage.

Having prepared everything you need for work, you can begin assembly. In practice, making a snow blower with your own hands will take no more than 5–6 hours of time.

What can be made from a Druzhba chainsaw

Techniques that you can make with your own hands from a chainsaw Friendship 4 has a large list. Everything is limited only by the master’s imagination. There are many videos published on the Internet with detailed descriptions of step-by-step making of homemade products. As part of the article, we have collected only the best videos, based on which you can easily make the technique you need. The simplest homemade product is considered to be a boat motor, and the most complex is an all-terrain vehicle, a motorized dog, or a lawn mower. Here are examples of homemade products from simple to complex.

Tire knife

This craft is not directly related to the Friendship 4 chainsaw, but is in demand because... The knife from the Friendship chainsaw tire holds an edge very well and is resistant to corrosion. For manufacturing, you only need the saw bar itself. The price on the secondary market varies from 200 to 500 rubles. To implement the craft, we suggest watching an interesting video, the author of which describes in detail how to make a kitchen knife from a tire. The peculiarity of the video is that the author shows a simple method of making a hole in the steel of the handle, without drilling.

Bike

To make a bicycle with an engine from a Druzhba chainsaw, you will need the saw itself and a bicycle, preferably a Kama with a rack. Homemade manufacturing process:

Attach the engine to the bicycle frame.
Route the throttle cable and trigger to the steering wheel.
Connect the bicycle drive wheel and the pulley on the saw motor with a chain.

For visual instructions, we recommend watching a video of the finished homemade product.

Mower (lawn mower)

To make a mower, you will again need the Druzhba 4 chainsaw itself, small wheels, a knife and rolled metal for making the body and protective casing. The knife will fit either from a brush cutter or from a lawn mower, it all depends on what working diameter will be specified by the project. We present to your attention a video review, the author of which made a mower from a Ural chainsaw (there is no significant difference from Druzhba, which is why we recommend watching it).

boat motor

Converting a chainsaw into a boat motor will be much more difficult than converting it into a bicycle or mower. The product will be aimed at contact with water, and as you know, you need to be extremely careful with it. According to the recommendations of many craftsmen, it is better to use the drive and shaft from an old outboard motor. The engine is from Friendship 4. All that remains is to connect them together. For example, we recommend watching an interesting video, the author of which made a boat motor from a Druzhba 2 chainsaw. The author demonstrates the operation of the saw in a barrel of water.

Video reviews and lessons on how to make a snow blower

Reviews from owners of homemade snow blowers Any man who has assembled a snow blower with his own hands will name many advantages of this design. The main advantage is accessibility, low cost, and the ability to work with common materials and tools that everyone has in their garage. For inexperienced craftsmen, this activity may seem complicated, but you can quickly figure it out, thanks to the many training videos, diagrams and drawings on how to assemble a snow blower from a chainsaw with your own hands.

“I use a snow blower that I built a couple of years ago. I found my father’s old Druzhba chainsaw in the garage and bought some tools, sheets and pipes. On the Internet I found many diagrams on how to properly assemble snow blowers with your own hands, many videos and recommendations. I slightly corrected the drawings; I am an engineer by training. As a result, we have a working machine that efficiently and quickly removes excess snow from the yard.”

“My regular snow blower broke and I still couldn’t buy a new one. A neighbor advised me to assemble it myself using a chainsaw. I’ve never done this before, my arms are growing out of my shoulders, but I couldn’t do it without the help of an experienced neighbor. We took the engine of an old Shtil chainsaw and bought additional fasteners, metal pipes and sheets. A couple of days of work and an excellent homemade snow blower is ready. The power is quite large, it removes snow quickly, in any case, faster than working with your hands and a shovel.

Advantages: low cost, convenience, availability of materials, performance

Disadvantages: it took a lot of work with my hands and head, but it was worth it.”

Rework principle

The basis of almost any homemade chainsaw is its use as a universal drive that can be used for a huge number of different devices. The scope of their use is very wide: cutting stone and metal, pumping water, removing snow, drilling wells and holes, driving, moving various objects, swimming and even flying.

Realize the potential capabilities of a chainsaw using a variety of accessories and attachments. The basis of any modification is the simple principle of engine power take-off: the device necessary for the master is connected to the output shaft. The presence of a powerful motor, compact dimensions and relatively light weight of this tool, autonomy and the ability to work in almost extreme conditions make its capabilities truly limitless. Of no small importance is the practical design of the clutch, which protects the components and systems of the saw from damage and overload. The tool, made from a chainsaw, is distinguished by its tightness, so it can be used in almost any position.

Generator

A chainsaw with a 2-stroke engine with a power of 2-3 liters is suitable for production. With. Electric motors from old washing machines are often used as electric generators. The combination of these devices makes it possible to obtain an output voltage of 220 V. The power of such a gas generator is sufficient for lighting, powering electrical appliances and tools, and household appliances.

A bracket is made and the electric motor is attached to it. Install the resulting structure on the outer end of the chainsaw bar. At the same time they provide:
the location of the pulleys of both devices in the same plane.
The output shafts of the engines are equipped with pulleys of suitable diameter.
Put a belt drive on the pulleys.
A device is made to regulate the speed of a chainsaw motor. A bolt is used, which is attached to the handle of the latter using a clamp. Tightening it leads to an increase in the number of revolutions, unscrewing it leads to a decrease.
The external starting winding of the electric motor is supplied with 2 capacitors, which are designed for a voltage of 400-450 V and have a total capacity of 10 μF. Their connection is parallel.

What can be made from a chainsaw

All homemade products can be divided into 2 groups:

the simplest devices (grinder, ice screw, pump, winch, walk-behind tractor, outboard motor, bicycle, moped);
more complex mechanisms and objects (sawmill, snow blower, snowmobile, snowmobile, power plant, helicopter, solid forged knife).

To manufacture all of the above devices, you can use various brands of chainsaws. When choosing them, you should take into account the required power for normal operation of the modification. Most often, the following brands of chainsaws are used for the manufacture of various devices: Druzhba, Shtil, Ural.
