In the hands of craftsmen, an ordinary chainsaw, originally intended for sawing wood, becomes a truly multifunctional device. Moreover, the breadth of its application is simply striking in its diversity. On sale meet different kinds special attachments that significantly expand the capabilities of chainsaws. These include the following attachments: a gas cutter, a clearing machine, a pump for pumping water, a motor, a brush cutter, a snow blower, and others. But, despite this, many craftsmen rework chainsaws on their own, using improvised materials. Homemade products from a chainsaw with their own hands can be made by almost any person who is more or less versed in technology.
Rework principle
At the heart of almost any homemade chainsaw is its use as a universal drive that can be used for a huge number of different devices. The area 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.
They realize the potential of the chainsaw using a variety of attachments and attachments. At the heart of any alteration is a simple principle of engine power take-off: a device necessary for the master is connected to the output shaft. The presence of a powerful motor, compact size and relatively light weight of this tool, autonomy and the ability to work in almost extreme conditions make its possibilities truly limitless. Of no small importance is the practical design of the clutch, which protects the units and systems of the saw from breakage and overload. The tool, made from a chainsaw, is distinguished by its tightness, so it can be used in almost any position.
What can be made from a chainsaw
All homemade products can be roughly divided into 2 groups:
- most simple devices(grinder, ice screw, pump, winch, walk-behind tractor, boat motor, bicycle, moped);
- more complex mechanisms and objects (sawmill, snow blower, snowmobile, snowmobile, power plant, helicopter, solid-forged knife).
For the manufacture of all of the above devices, you can use various brands chainsaws. When choosing them, one should take into account the required power for the normal operation of the rework. Most often, the following brands of chainsaws are used for the manufacture of various devices: Friendship, Calm, Ural.
The most simple homemade chainsaw
Below are the different options for devices made from chainsaws. Everyone will be able to use such ideas in their household. From a chainsaw with a small amount of additional materials, you can make:
Bulgarian... The main system of such a device is a bearing assembly with a shaft. At one end of it, a driven pulley is installed, which rotates with the help V-belt... On the other, a mandrel for cutting wheels is fixed. Depending on their brand, such a grinder can be used to cut stone, metal, brick and other building materials. 
Ice screw... For good operation of the device, the speed of the auger should not be high, therefore it is necessary to use a gearbox made in the form of a worm or V-belt transmission... Such a device can be used in the construction of a foundation from screw piles and for other earthworks.
Water transfer pump can be used for garden irrigation, emergency water supply, drainage of reservoirs or flooded basements. This nozzle is a simple centrifugal pump equipped with a saw bracket and a pulley that drives the pump turbines.
Winch which uses a chainsaw drive. The pulling force of such a device directly depends on the power of the saw motor. By using an additional unit, it can be significantly increased. This device is equipped with such additional parts as a tap-off block, hooks, belts, anchors. 
Chainsaw outboard motor- a great alternative to buying an expensive engine. To ensure the movement of 20 km / h, it is enough to install on the boat a home-made outboard motor with a gearbox (gear ratio 2: 1) and a 3-blade propeller with a diameter of 210 mm. In this case, the fuel consumption will be only 1 liter per hour of engine operation. 
Motor cultivator almost everyone can assemble from a chainsaw. This requires a transmission system (2 gears). With its help, the energy of the motor is transferred to the drive wheel, thanks to which the working mechanism is set in motion. Of course, such a cultivator is of little use for cultivating a huge field, but its power is quite enough for a personal plot. 
Chainsaw moped... For such a vehicle, you will need a base, for example, an old bicycle. A chainsaw motor is attached to its frame. As a rule, a gear transmission is used on such a vehicle. If a mountain bike is used for conversion, then a gearbox will be needed to control the speed of movement.
For the manufacture of the following devices, the master needs some technical knowledge and experience with various mechanisms and materials. From a chainsaw using various components, you can create the following homemade products:
Sawmill from a chainsaw which can be done with a metal frame. A chainsaw is rigidly attached to this frame. The workpieces can be guided along the track. There are other options for sawmills. So for a device designed for longitudinal sawing, you will need an adapter attached to the bus located at its base and a guide that sets the direction of movement of the adapter. The guide is installed on a board attached to the log to be sawn. With this sawmill, logs can be divided into 2-4 parts.
Portable power station from chainsaw is able to provide energy in any places remote from power grids. To create it, you need the following components: a gear reducer, a generator, a metal bar, a drive belt, a control panel. Powerful saws Druzhba and Ural are most suitable for such a device.
Homemade snow blower can be made from a saw whose power exceeds 3 kW. For it, it is necessary to mount a screw assembly with blades made of durable but elastic material. The chain connects the motor to the auger unit through a pair of gears. Both wheels and runners can be attached to the snow blower. Any large diameter pipe can be used to throw snow.
Homemade chainsaw snowmobile by its design, it is a little more complicated than a sawmill. A snowmobile consists of a frame, engine, track and steering. He also needs runners to move. To create it, you need to take out the gas and the clutch on the steering wheel. You should also consider a shock-absorbing suspension system for the carrier frame. Since the chainsaw does not have a transmission, the clutch on a homemade snowmobile is centrifugal. A poly V-belt and a chain are also used. You can use old bike parts for the steering gear. It is reworked so that the center axis moves the traction skis. To increase traction, a traction gear is installed on the drive shaft of the caterpillar. Engine power must be at least 5 HP.
Chainsaw snowmobile much easier to do than a snowmobile. A large screw, directly rotated by the chainsaw engine, provides the driving force. A serious limitation of the use of such snowmobiles due to their lack of maneuverability is the low power of the chainsaw engine. Driving through snow-covered fields requires an engine with a power of at least 12 hp.
Chainsaw backpack type helicopter... Such an aircraft can take off only when at least four engines with a total power of 20 hp or more, operating in a coordinated mode, are used in its design. It will not work to make it out of one chainsaw. Using such a homemade apparatus can be life-threatening.
Can be done by people familiar with blacksmithing. To do this, first of all, the old chains are divided into pieces, which are then welded into blanks. They are heated in a crucible to 850 ° C. The workpieces are pressed until they get rid of the voids between the links. Further, the metal is amenable to forging until the workpiece is given the necessary shape and strength.
What did you do with a chainsaw?
- This is a device that is sometimes simply irreplaceable in the household. Work speed, high performance, ease of use are just a few of the advantages of this device.
However, not all consumers know that the use of a chainsaw is not limited exclusively to working with wood, and many of its structural parts are so functional that it becomes possible to build completely new mechanisms that are completely different from the original design of a gasoline apparatus.
This is due, first of all, to design characteristics chainsaw: its engine is reliable and unpretentious, and fuel leakage is almost completely eliminated. What can be made from a chainsaw will be discussed further.
Features of creating a motor-drill from a gasoline saw
In order to make a motor-drill with your own hands from a chainsaw, first you need to adjust the engine speed, since you will not need maximum performance for comfortable and safe work.
An element such as a gearbox, which needs to be fastened to the chainsaw engine, can cope with this task. At this stage, it is important to think over the fastening system so that the parts of the future structure are tightly connected to each other.
For the device to work reliably, the drill and knives for it must be selected so that these parts coincide in rotation with the "native" mechanism.
Chainsaw motor-drill. The video demonstrates the use of the tool as an ice drill.
Chainsaw scooter device
With the help of the chainsaw engine, you can assemble not only devices for manual use, but also a full vehicle operating on combustible fuel. One of these designs is a homemade scooter with a chainsaw motor.
To create this device, you need a regular scooter equipped with a system hand brake and inflatable wheels. The saw motor must be secured to the rear platform of the scooter and make sure that the star line of the motor and rear wheel matches.
To control the level of energy supply to such a scooter, the manual accelerator must be connected to the wires responsible for turning the chainsaw motor on and off. In case of difficulties, installation of a special pedal is allowed.
A bicycle powered by a chainsaw, the so-called moped. The principle of using the engine is the same as that of the scooter.
How to mount a sawmill from a chainsaw?
One of the devices where the structural parts of the chainsaw are used to work with wood, not only for the purpose of cutting it, is a sawmill, with which you can cut high-quality beams of the required diameter.
An ordinary gasoline saw will not work in this case, since holding the tool on the weight will not achieve the accuracy of the cut. That is why a mechanism was invented, where the tool is tightly attached to the guides by means of four screws and moves freely along them, guaranteeing an extremely even cut.
The sawmill from a chainsaw is designed so that the beam itself in this system is in a stationary position, and the cutting mechanism is mounted at the required height based on the thickness of the board being processed.
Chainsaw as the basis of a boat motor
System boat engine quite simple, but in order to eliminate unnecessary costs for an expensive option, you can always equip an easy-to-operate outboard motor from a chainsaw.
Ease of installation lies primarily in the absence of a transmission. All that is required to install the motor from the saw to the boat is to connect the boat's propeller to the engine by installing a special adapter designed to transmit torque.
The correct fastening of such an engine to the boat should take into account the installation of the propeller shaft at a slight slope to the water.
This design will be a real gift for fishing enthusiasts and will provide economical fuel consumption along with sufficient work power and speed of movement on the water.
Chainsaw outboard motor - video. Manufacturing details and application demonstration.
The principle of designing a snowmobile based on a chainsaw engine
Via gasoline engine saws can be mounted on vehicles that are able to move not only on a hard surface, but also on snow.
It is realistic to build a chainsaw based on the engine, but here the design will come out more complicated. The frame of the mechanism needs to be equipped with a suspension with shock absorbers, as well as to equip the device with a clutch.
An ordinary bicycle steering wheel can act as a control mechanism, it is only important to equip it for the movement of a snowmobile. In addition, it is important to be careful about torque delivery, as the lack of a gearbox means that the vehicle can only move with a properly mounted clutch.
Creating a walk-behind tractor from a gasoline saw
A walk-behind tractor is an irreplaceable device in agriculture. But factory equipment is not cheap, so a good and inexpensive option is to equip a walk-behind tractor from a chainsaw, where the latter mechanism acts as a power unit.
Power is enough to use the vehicle on the farm. Little fuel is required to work, and the assembly process is not complicated at all.
For the frame of such a walk-behind tractor, pipes that are welded according to the type of rectangular section should be used. There are two sprockets in the mechanism: the leading one and the one located in the intermediate shaft. You can choose any wheels, but experienced experts recommend using rubber samples.
If there is no money for new walk-behind tractor, then you can make it from a chainsaw as in this video.
Chainsaw-based aircraft
The use of a chainsaw is not limited to by land transport, but equipping with one sample a full-fledged aircraft capable of lifting one person into the air is quite problematic.
The power of a standard device is not enough for this, since for such a design at least four engines from standard chainsaws are required, operating simultaneously at maximum speed.
Chainsaw grinder device
You can sharpen metal structures, process wood and stone products and perform a wide range of work using a grinder. But there is always an opportunity not to buy a ready-made tool, but to make it from scrap parts. In this case, the chainsaw motor acts as the main driving force that rotates the grinder's disk.
Self-designed equipment is capable of performing many functions; in addition, the manufacturing process is simple: a pulley is mounted on one of the shaft parts, the rotation of which is carried out by a special belt.
The other end of the shaft is equipped with a mandrel for grinding wheels. A chainsaw grinder is a versatile and indispensable device in the household, which is distinguished not only by its ease of manufacture, but also by its ease of use.
How to equip a motor cultivator from a chainsaw?
Almost any owner can build a motor cultivator from a chainsaw. The most important parts in this design are the engine and the transmission system with two gears, with the help of which the drive wheel is propelled.
A home-made motor-cultivator is capable of performing many functions: tillage, fertilization and digging, as well as sowing crops. Of course, it is impractical to operate such a mechanism on a large field, but for a summer cottage such a motor-cultivator is perfect, and its power will be quite enough.
Thus, we can say with confidence that a variety of homemade chainsaw products can significantly make life easier and at the same time help save a significant part of the financial resources spent on components for expensive factory equipment.
In conclusion, one more video, in which, by example, it is described how to make a "Mole" motor-cultivator with an engine from the "Druzhba" chainsaw.
The Russian people are rich in Kulibins and Lefties…. How many unexpected and useful inventions have been made by Russian craftsmen - you cannot count! What unexpected things did not find their second life! This share also did not go around the chainsaw. Today we'll talk about homemade chainsaw products. Since there are a lot of such inventions, I will tell you only about some of them. But it seems that the heading "do it yourself", which will include home-made devices from a chainsaw, will be firmly registered on the blog. And separately in each issue I will talk about homemade products from Druzhba and Ural chainsaws. So, a little overview.
One of the most popular homemade gadgets and alterations from the chainsaw is the outboard motor. Such motors can be used, as a rule, on rubber boats and small PVC boats. Installing them on metal and large PVC boats is impractical due to lack of power. Here are a few homemade chainsaw-boat motors.
Outboard motor from the Stihl MS 180 chainsaw
The first outboard motor from the saw is made on the base. The gearbox is made in a very original way - by splicing parts of the drive "grinder" and brushcutters. From this gearbox, a shaft goes upwards inside a pipe made of aluminum, which goes to a coupling made of fluoroplastic. The drive gear from the chainsaw is inserted into the clutch.
In this variant outboard motor from chainsaw made remote control "gas" of the classic boat type. The chainsaw is mounted on a rotating base and by turning the handle we control the direction of movement.
The idea of noise reduction is very interesting.
running engine. A standard silencer of the 180th Calm was taken, a pipe is welded to it, which brings exhaust gases into the water. In order for the gases to escape more freely, a water intake is made at the end of the pipe.
In my inexperienced opinion, the power of the 180 engine is still not enough to fully replace the outboard motor.
Watch the video do-it-yourself boat motor from the Stihl 180 chainsaw.
Outboard motor from the Ural chainsaw
The second outboard motor is made from a chainsaw. The author took two gearboxes from the Druzhba chainsaw, fuel tank from petrol cutters and the engine itself from the Ural chainsaw. The design here is much simpler than in the first version due to the fact that only the engine from the chainsaw is used, and not the whole saw. The power of the Ural chainsaw is 5 Horse power quite enough for normal use as a full-fledged boat engine. The only point that I would like to note is the installation of a more advanced silencer would not be superfluous.

Chainsaw ice screw
This ice screw is made on the basis of the most popular chainsaw - Stihl MS 180. Its device is very simple - a screw, articulated with a shaft. The shaft goes to the gearbox, which is connected to the chain saw drive sprocket. There is also an additional handle on the chainsaw mount for ease of use.It is worth noting that for the normal functioning of the ice screw and reducing the load, it is worth using a gearbox with a reduction ratio of about 5: 1, - 7: 1. This will make the chainsaw ice screw more reliable and convenient to use. If you want to make a motor-drill, then it should be borne in mind that, unlike ice, there can be stones, metal and other troubles in the soil. This means the need to install a more powerful engine (that is, more powerful chainsaws) and a stronger gearbox.

That's all for today))) To be continued!
In contact with
Chainsaw masters are not always used for their intended purpose; as a rule, it serves as a powerful drive in all kinds of mechanisms. The ingenuity of our craftsmen has given rise to numerous and very diverse homemade chainsaw products, surprising in their originality.
The advantages of the chainsaw as a drive are compactness, light weight and high power. Any master who is able to grind a part, can perform locksmith work, use a grinder and a welding machine, can make interesting structures based on a chainsaw.
In order for the device, which is driven by a chainsaw, to function properly, accuracy in the dimensions of parts and care during assembly are necessary. So, knowledge of the basics of drawing and designing mechanisms in this matter will come in handy.
What homemade chainsaw have already come up with
The first use of a chainsaw from the point of view of many developers is to dissolve logs with its help. But, if you hold the chainsaw on the weight by hand, the accuracy of the cut suffers, especially with a bar length of four or six meters. So that the cut does not go away from the desired line to the side, they came up with the idea of rigidly fixing the chainsaw in the frame, which moves along the 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 timber, is fixed with four screws.
Thanks to the precise movement of the frame, a smooth and neat cut is obtained. You can also cut boards in the same way, but due to the large thickness of the cutting chain, you get a lot of waste.
Chainsaw-winter transport
They managed to use the chainsaw as an engine for homemade snowmobile... Here the design is much more complicated than a sawmill. In this case, in addition to making the snowmobile frame, you will need to make a suspension with shock absorbers, to conduct gas and clutch control to the steering wheel.
In addition, you will need to find the drawings (or design yourself), according to which the snowmobile caterpillar will be made, and think over the transfer of torque from the chainsaw to the caterpillar. They put on such a snowmobile centrifugal clutch with a chain and a V-ribbed belt (after all, the chainsaw does not have its own transmission). In order to increase traction on the drive shaft of the caterpillar, a gear with a diameter larger than the drive sprocket of the chainsaw (the so-called "traction gear") is installed.
For the steering gear, as a rule, they take the handlebars from the scooter and bicycle and redo it without problems so that it turns the skis of the snowmobile. Such transport requires an engine with a capacity of at least five horsepower, so if you are making a snowmobile, then use the Ural chainsaw.
If we consider transport for the winter, it is much simpler than a snowmobile, the design of a snowmobile. In them, a large propeller is attached directly to the shaft of the rear-mounted chainsaw. True, the low power of the chainsaw limits the passability of such sledges with ice on the river or a rolled road. For racing on snowy fields, you need an engine of at least 12 horsepower. The same restrictions do not allow replenishing homemade products from a chainsaw with a backpack helicopter. Unless, if you use two motors and the master manages to make them work in concert.
Homemade chainsaw - the engine is great
This is not to say that there will be a lot of sense from such a design, but many make such a kind of transport, just to test themselves and others to show their skills as a designer and mechanic.
The basis is an old bicycle, which is not a pity, and the well-known Druzhba chainsaw. Power transmission to the wheel is carried out using a bicycle chain and a gear pair.
Sometimes they take a mountain bike, a variator gear and a gearbox are installed between the chainsaw and the wheel (in order to move slowly but surely, you need ratio 18: 1). Shock absorbers and a brake are installed on such an "advanced" model.
Boat engine
Such a design is simple to implement, the outboard motor does not need a transmission, you just need to grind an adapter that will transmit torque from the saw pinion to a standard propeller shaft and boat propeller.
http://www.youtube.com/watch?v=rMRogHwQsck
Usually, either homemade engine they are mounted on the boat so that the propeller shaft is immersed in water at a slight angle, or they are not too lazy to assemble a gearbox that transfers the rotation of the shaft at a right angle to the propeller.
Chainsaw motor cultivator
Many have managed to make a simple motor-cultivator out of a chainsaw, in which a pair of gears increases the tractive effort of the engine and transfers it to the drive wheel. It must be understood that the insufficient power of the saw motor will not allow making a real walk-behind tractor in this way.
Resourceful craftsmen show their talents for the construction of snowplow equipment. Known models are based on a three-watt chainsaw "Calm", which is installed, for simplicity of construction, on sled runners. The main thing is to make a high-quality auger assembly and pick up a gear pair, and the chainsaw engine doesn't care what it rotates.
For such a snowblower, they take galvanized steel for the manufacture of a fence, blades are made of thick cord rubber, and an ordinary plastic sewer pipe will serve as a snow thrower.
Chainsaw-based helicopter
Although many inventors are looking for ways to make a small, single-seat helicopter based on a chainsaw, it still lacks the power to fly. As shown by engineering calculations, a mini-helicopter needs at least four forced chainsaws that work in concert and with an increased number of revolutions.
A motor-drill made of a chainsaw will greatly facilitate the installation of the foundation on screw piles, the 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 gear (worm gear).
Chainsaw winch
Using a chainsaw, it is easy to make a winch, with an effort of up to one and a half tons. Such a device will help to raise a massive load to a height, remove a sawn tree, pull a boat ashore or a stuck car on the road.
A small gasoline power plant is useful in the household. A generator, a Druzhba or Ural chainsaw are mounted on a solid frame and connected to a gearbox. A pulley is fixed on the gearbox shaft, from which the cord belt transfers rotation to the generator, which will provide household electricity in the event of a power outage or lack of power.
So, although this tool itself is familiar to everyone and its purpose seems unambiguous, craftsmen come up with many interesting designs. As you can see, homemade chainsaw products 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, the engine of which is a chainsaw.
