What can be done with a chainsaw. What can be made from a chainsaw - homemade from a chainsaw

In the hands of craftsmen, an ordinary chainsaw, originally intended for sawing wood, becomes a truly multifunctional device. At the same time, the breadth of its application is simply striking in its diversity. On sale there are various types of 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 \u200b\u200btheir 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. Any alteration is based on 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 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 saw units and systems 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:

• the 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 of 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 a 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 reducer 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 watering the garden, 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.

Winchwhich 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. Typically, such a vehicle uses a gear train. If a mountain bike is used for conversion, then a gearbox is needed to control the speed of movement.

For the manufacture of the devices below, 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 chainsawwhich 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 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. A 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 slightly 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 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 chain are also used. You can use old bike parts for the steering gear. It is redesigned 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 insufficient cross-country ability is the low power of the chainsaw engine. Driving through snowy 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 device 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 blanks are pressed until the voids between the links are removed. Further, the metal is amenable to forging until the workpiece is given the necessary shape and strength.

What did you do with a chainsaw?

The chainsaw is very popular among DIYers, as it is a universal drive for original homemade designs.

Light weight and solid power in combination with compact dimensions allows this “lumberjack's dream” to be aggregated with an ice screw 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, a grinder, and, if necessary, can stand up to a lathe.

In this matter, knowledge of the basics of design and drawing will be very useful, since the accuracy of all sizes and build quality are the main conditions for the normal functioning of the unit, powered by a chainsaw.

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

DIY options

The first thing that comes to mind when you think about what can be made from a chainsaw is using it as a sawmill. Many developers had to dissolve the logs onto the timber with this tool.

Holding the saw in your hands is very difficult to control the accuracy of the entire cutting length. Therefore, with a three or four meter length of a log, it greatly deviates from the intended line. The solution to this problem is quite simple. For this, the chainsaw is rigidly fixed on the frame, which moves along the guide profile.

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

The sawmill from the chainsaw will also work without problems on the boards, 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 home-made snowmobile from a chainsaw is more complicated in design than a sawmill, since here you need to take out gas, clutch, and also take care of the shock-absorbing suspension of the supporting frame on the steering wheel.

In addition, you need to develop 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 centrifugal with a poly V-belt and a chain.

To increase traction, a "traction" gear is placed on the drive shaft of the caterpillar, the diameter of which is larger than the size of the chain saw drive sprocket.

The steering gear is usually not a problem, 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 engine power of the snowmobile must be at least 5 horsepower, so for this purpose it is better to use the Ural chainsaw.

The winter line of home-made vehicles will be supplemented by a snowmobile from a chainsaw, which is structurally simpler than a snowmobile. They are driven by a large-diameter propeller that directly drives the gasoline engine.

A significant limitation for the passability of such a machine is the low power of the chainsaw. Therefore, you can move on them only on a flat surface of rolled snow, ice of a frozen lake or river. For trips through the fields, you will need an engine with a capacity of at least 12 "horses".

The same should be known for those home inventors who would like to make a backpack-type helicopter out of a chainsaw. 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, and not for practical use. The main driving force behind its creator is the desire to test his strength as a mechanic and to prove to others the original use of this cutting tool.

The basis for the design usually becomes the old grandfather's chainsaw Friendship and no less ancient bicycle, with which you can carry out any experiments on altering the frame for mounting the drive.

The transmission of power here is carried out through a gear pair using a bicycle chain, and the start of such a homemade product resembles preparation for cutting firewood.

Less common are more advanced models based on a mountain bike equipped with reliable brakes and shock absorbers. Such a moped from a chainsaw is equipped with a gearbox with a gear ratio of 18: 1 and a variator gear, which makes it comfortable to 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 boat motor does not need to install a transmission. For him, you will need to make a reliable adapter from the saw drive gear to the propeller shaft on a lathe. The propeller can be used from a standard outboard motor.

The photo shows an option in which a gearbox stands in front of the propeller, which changes the angle of rotation of the shaft by 90 degrees. In simpler models, they do without it, securing the engine to the boat so that the shaft is submerged 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 a lack of power and traction. But many home craftsmen managed to build a light motor-cultivator on its basis.

The design of such a machine is very simple: a motor rotates a pair of gears and transfers an increased tractive effort to one drive wheel.

Snow blower

The chainsaw motor does not care what it is turning - the cutting chain or the auger mechanism of the snow blower. It all depends only on the design abilities of the creator and his ingenuity.

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

The most critical part that determines how well a homemade snow blower does 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.

Frame design

A plastic sewer pipe can be adapted for the snow thrower by fixing it to the intake body.

Chainsaw asks to 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 for airspace exploration. Therefore, no one has yet succeeded in making a knapsack helicopter out of one chainsaw.

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

Motobur

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

Since the ice screw works at low speeds, to adapt the motor of the chainsaw, 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 raise a heavy load to a height, pull a boat on land or move a sawn tree.

The power of such a homemade product depends on the power of the used chainsaw, and its tractive effort can reach 1500 kg. Such a winch should be equipped with a sling strap, hooks and anchors for anchoring to the ground, tree trunk or vehicle.

Power station

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

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

A good owner will not throw anything away in vain, especially when it comes to high-quality metal. If you understand the nuances of metal heat treatment, you can make solid forged chain knifethat has served its resource.

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

Traditionally, a gasoline saw is used to cut wood. However, in times of total scarcity, craftsmen have adapted to using it as a drive for other machines and mechanisms. Anyone who understands mechanics and knows how to hold a tool in their hands can make homemade products from a chainsaw. Thus, you can build an interesting and useful device in everyday life.

Useful Chainsaw Items

It all depends on the fantasy of the master.... From a chainsaw you can make:

• snowmobile;
• motorized towing vehicle;
• motorbike (moped);
• motor cultivator;
• lawn mower;
• motor drill;
• boat motor;
• snow thrower.

A snowmobile is very simply done on the basis of a small bicycle. A ski is placed in front, a pair of ultra-low pressure wheels are placed on the back on a solid axle. Such a homemade product from the Druzhba or Ural saws will run quite briskly on ice or rolled snow.

For deeper loose snow, such a snowmobile model is unsuitable, the saw engine power is not enough. A snowmobile that uses a caterpillar as a propeller is more versatile. The simplest caterpillar is assembled from a conveyor belt. The role of the hooks is performed by flat wooden slats attached to the tape. Because of this, such snowmobiles are traditionally called "stick insects".

The same principle is used in the construction of motorized towing vehicles (motorized dogs). This option is even preferable to a regular snowmobile, since this home-made product from the Ural chainsaw allows you to move even on loose snow. In addition to the engine, a gearbox must be installed on a motorized towing vehicle or snowmobile to reduce the speed while increasing the torque.

A bicycle with a motor from a chainsaw with your own hands is the easiest to make. Any frame bike is suitable for this. The throttle control cable is routed to the steering wheel. Chainsaw and bike chains have the same links, so no special gears are required. The torque can be directly transferred to the rear wheel of the bike. It is only necessary to put a sprocket with an increased number of teeth on the rear wheel to increase the gear ratio and increase power. This will reduce the speed. This is a good thing, since a regular bicycle is not designed to travel at speeds over 20 kilometers per hour.

A motor cultivator can also be made by using a chainsaw as a drive. However, the power of a walk-behind tractor from a chainsaw is small, and it does not have wide application in agriculture. It is unrealistic to plow virgin soil with such an apparatus, but to dig furrows for planting potatoes is quite.

The mower is also easy to assemble. The basis is a conventional four-wheeled hand trolley. An engine from a chainsaw is mounted on top of it. The torque is transmitted to a rigid shaft, the other end of which is brought out under the bogie bottom. There, either a metal knife or a block with a trimmer line is attached to it.

To make a motorized drill, you need a small worm gear and a screw from a fishing ice screw. With this device, you can effortlessly drill a large number of holes on the river in winter. If the drill is planned to be used to drill holes in the ground, the auger and the nozzle will have to be strengthened.

To build a homemade boat motor from a chainsaw, a gearbox is not needed. You just need to weld a frame with two clamps for attaching to the boat transom and install the propeller on the shaft. Those who made homemade trimmers with their own hands can easily make a boat motor from a chainsaw.

It is possible to construct a simple snow blower from a chainsaw. To do this, you need to install the saw on the sled runners and add a homemade auger assembly. The slide snow guide can be made from a regular sewer pipe.

The power unit from the saw can even be put on a scooter.

Our hands are not for boredom

The Druzhba chainsaw is best used as an engine and drive for the following devices:

• generator;
• water pump;
• sawmills;
• circulars;
• grinders.

The simplest belt drive from a chainsaw to a car generator will provide a country house or summer cottage with electric light. In the same way, you can connect it to a centrifugal pump to pump out water from the basement.

By adding a worm gear to the chain saw, you can easily construct a simple winch.

A semblance of a band sawmill is easily constructed from a chainsaw, where the carriage with the saw attached to it will move instead of the tape. This design will allow you to dissolve the trunk of the tree yourself into a bar. Theoretically, you can also saw boards, but due to the wide cut there will be large losses.

Technique 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 on 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 single-seat flying platform with eight engines from the Druzhba chainsawsynchronized in one block. Prototypes of these developments have been repeatedly shown at various exhibitions. Despite this, such models were never mass-produced.

The dream of the sky for those who like to design something from chainsaws is still a dream. Nevertheless, attempts to make a single-seat knapsack helicopter using engines from the "Ural" or "Druzhba" do not stop.

The engine of any chainsaw can be used to make simple equipment: from a mower to a helicopter. It all depends on the tasks and goals of the master. But not everyone understands why the engine is from the Druzhba 4 saw. Not everyone fully understands how and what can be done with their own hands. This article was written to help the wizards and fill this gap.

We will name a number of arguments why it is worth using the Druzhba chainsaw for alteration:

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

What you need to work

To do it yourself, homemade products from the Friendship chainsaw, you need a set of tools of a novice master, a desire and an idea. The main tools required for work are a grinder and a welding machine. You already have a desire, otherwise you would not be on this page. You will find the very idea for converting the Friendship chainsaw into any unit in this article.

In the article, we offer only an idea, without step-by-step instructions for action. Otherwise, the article would be ten times larger. If after reading there are 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.

What can be done from a chainsaw Friendship

The technique that you can do with your own hands from has a large list. Everything is limited only by the imagination of the master. A lot of videos have been published on the Internet with a detailed description of the step-by-step making of homemade products. As part of the article, we have collected only the best videos, on the basis of which you can easily make the technique you need. A boat motor is considered the simplest homemade product, and an all-terrain vehicle, a motorized dog, a lawn mower is considered the most complex. Here are examples of homemade products from simple to complex.

Tire knife

This craft is not directly related to the Druzhba 4 chainsaw, but it is in demand, because a knife from the Friendship chainsaw tire holds sharpening very well, is resistant to corrosion. For manufacturing, you only need the tires from the saw 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.

Bicycle

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 trunk. Homemade craft process:

1. Secure the motor to the bike frame.
2. Route the throttle cable and trigger to the steering wheel.
3. Chain the drive wheel of the bike and the pulley on the saw motor.

Mower (lawn mower)

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

Boat motor

Converting a chainsaw into a boat motor will already be much more difficult than a bicycle or a mower. The product will be aimed at contact with water, and with it, as you know, you need to be extremely careful. According to the recommendations of many craftsmen, it is better to use the drive and shaft from an old outboard motor. Engine from Friendship 4. It remains only 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 a saw in a barrel of water.

Sawmill

To make a sawmill from a chainsaw, it is enough to make a device for longitudinal dissolution of a log. Its task is to keep the saw bar in a flat plane relative to the log. For a visual representation, we recommend watching a video demonstration of how to work. From the video, it becomes clear that homemade products require a minimum of materials - ordinary rolled metal (shaped pipe).

All terrain vehicle

Converting a chainsaw into an all-terrain vehicle is already very difficult, but still possible. There are many videos on the Internet whose authors have implemented this idea. The whole point is that you need to make your own chassis: frame, wheels, drive, etc., and the Druzhba 4 chainsaw will be used as an engine. The only recommendation is to use ordinary cameras instead of wheels, connected around the perimeter, such wheels are essential lighter than those with tires, respectively, the motor will be much easier while driving.

For the review, we suggest watching an interesting video about a homemade all-terrain vehicle from a Druzhba 4 chainsaw. The home-made product uses a scooter, a goose, so this is most likely a snowmobile rather than an all-terrain vehicle.

Motorized dog (motorized towing operator)

Making a motorcycle dog from a Druzhba 4 chainsaw, as in the case of an all-terrain vehicle, also comes down to the initial development of the chassis: frame, caterpillar, control, etc. And the saw motor is just the driving force.

We offer you to watch an interesting video, the author of which shows how to make a motorcycle dog almost from scrap materials. For example, the caterpillar hooks are made of ordinary plastic pipes, and the entire frame of the motorized towing vehicle is welded from a regular small-diameter profile pipe.

Helicopter

Converting a chainsaw into a helicopter is most likely just an experiment, there is no practical application. On the Internet there are videos of aircraft, the authors of which have developed such projects and implemented them, for example, a homemade aircraft from a chainsaw.

Conclusion

Friendship 4 is ideal for DIY crafts. Inexpensive and affordable, it's not a pity to spoil, a lot of ideas for implementation. The main thing is desire, if there is one, then there will be a mower, and a boat motor, and an all-terrain vehicle, and much more. Good luck engineers!

Homemade from the Ural chainsaw make up most of the devices invented by craftsmen from such units. This is explained by the simplicity of the design, sufficient power and low weight of the chainsaw.

Snowmobile

They begin work with the frames of the snowmobile and the tracked block, which are made in the form of 2 welded spars. In the middle parts, 50x36 corners are used, metal plates of 2 mm thickness are installed in front and behind. In the latter, the edges are bent by 90 °, which adds rigidity to the details.

A hole is made in the front plate for the shaft driving the caterpillar, in the rear one for its second axis, which is a tension one. Near the latter, on both sides of the frame, tensioners for the track and chain drive are mounted.

5 brackets with open slots are welded to the side members from below. They have the axles of the track rollers supporting the track. The last 18, 3-4 pcs. on each axle - front and rear at the edges, middle - in a checkerboard pattern. The axles are secured in the grooves with nuts and locknuts.

The rollers are suitable for the unit used for sorting potatoes, the axles are for the potato digger. The axles are released, grind, and M10 threads are cut. Duralumin tubes of the corresponding diameter are placed between the rollers to fix the position.

For each spar, 3 racks are welded using 30x30 corners. Connect along the top with the same crossbars:

• to the front and middle, a steel sheet 2 mm thick is welded on the right side, on which a gearbox with an intermediate shaft of the chain drive is mounted;
• between another pair arrange a box with a lid that is a seat.

A transverse beam is welded to the front ends of the side members - the traverse of the front axle. To its ends there are bushings for steering skis, in the middle there is a rack that forms a motor subframe. All parts are from a water pipe with an outer diameter of 32 mm.

The caterpillar for the motorized dog is used from "Buran". It is shortened by 50 cm and sewn. Drive and tensioning gears are made according to the type of "Buranovsky" from strong plastic 1.5 cm thick.

For the drive shaft of the track, a pipe with an outer dimension of 28 mm is used. At the edges:

1. Flanges are welded to which gear wheels are attached through the holes.
2. The tips-pins are pressed into the shaft holes, the diameter of which is pre-machined to fit bearings 80204. One of the tips is made longer and a driven sprocket is placed on it, through which the shaft is driven into rotation. Fasten it with an M14 nut, under which the end of the trunnion is machined and threaded.

Similarly to the drive, but with 2 identical tips, a tension shaft is made.

The engine of the chainsaw is mounted through its frame on a motor subframe - a stand on the crossbeam. A gas tank is placed on top. The gearbox is turned 180 °, fixed on the site. A creeper is also installed on it - an intermediate shaft. Sprockets with 38 and 10 teeth are attached to it. The chains for transmission of rotation are taken from the "Voskhod", "Minsk" motorcycle.

The steering includes:

• support and steering skis, on which the levers are installed;
• bipod of the steering shaft, to which the ski levers are connected by rigid rods;
• motorcycle 2-link handlebar with throttle stick near the right grip.

The walls and bottom of the box are covered with 4-layer plywood or boards. Its lid serves as a seat: for its manufacture, they take 6-layer plywood, cover with a layer of foam rubber and leatherette.

Snow blower

The homemade product is simple, it is not difficult to do it yourself. First, a frame is made, which is welded from pipes of 3-4 centimeters in diameter. Its shape is U-shaped, with 2 additional crossbars located at the rear of the frame at a distance of 20 cm from one another.

Longitudinal frame elements are used to move the snow blower, being runners. Their ends are made oblique, the holes are welded to avoid clogging with snow. Crossbars are needed to accommodate the power unit.

The motor from the chainsaw is freed from the frame and reworked:

• remove the drive sprocket;
• a small sprocket is installed in its place, which is used as a drive in motorcycles "Voskhod", "Minsk".

Making a self-made snow blower auger:

1. For the shaft, use an 80-85 cm pipe section of the same diameter as for the frame. In the center, on the sides, 2 plates 13 cm long and 15 cm wide are welded. They are needed to eject snow.
2. 4 circles with a diameter of 30 cm are cut out of sheet metal with a thickness of 2-3 mm. The inner parts are removed - discs with a diameter of 22-23 cm. The remaining circular elements are cut in one place and stretched, giving them the shape of springs.
3. Each pair of springs is arranged symmetrically to the shaft, welded with one end to different sides of the central plates at their end sections. The other ends are connected to the shaft through metal spacers. The direction of the turns is towards the center of the shaft. The length of the screw part is 70 cm.
4. A metal case is made of sheet metal to accommodate the screw. It consists of 2 vertical sidewalls, in which the lower and front edges are straight, the back is made in a circle. The latter is covered with a sheet of metal. The dimensions of the body must ensure free placement inside the auger. The size of the gap is 5-7 cm.
5. The auger is inserted into the holes on the sidewalls. The ends are placed in bearings welded to the latter from the outside. On one side of the shaft, a driven sprocket from the same motorcycles is attached.

For the manufacture of a snow plow, a piece (10 cm) of aluminum pipe and a box are used, which are welded from sheet metal. The first is fixed in a hole, which is arranged in the center of the housing cover approximately in the middle of its width. The box is bolted to the segment.

The housing in which the auger is installed is placed at the front of the frame. The sidewalls are welded to the longitudinal pipes. The motor is fixed on the frame crossbars, placing the driving sprocket and the driven one, installed at the end of the auger shaft, in the same plane. The sprockets are supplied with a chain, not forgetting to arrange a tension mechanism (an additional sprocket, bolted to the sidewall of the auger body).

To control the unit, a tubular handle is arranged, a lever is brought to it, which regulates the fuel supply to the engine.

Boat motor

The saw headset is removed from the chainsaw engine, the drive sprocket is removed. The clutch is redesigned by grinding out a smaller cup and replacing the tightening spring, which makes it possible to reduce the mass of the unit and reduce the adhesion force. Connect the shaft of the motor and the gearbox through the coupling.

A channel is used for installation:

• in the upper shelf arrange the necessary holes for mounting the engine with a gearbox;
• the bottom shelf is provided with a hole, a tube is welded into it coaxially with the gearbox output shaft.

A shaft is threaded through the tube, which transmits the rotation to the propeller, and is connected to the output shaft of the gearbox. A fastening-rotary assembly is attached to it, which is used to install the motor on the boat transom, raise and lower the propeller into the water.

A gearbox is installed at the lower end of the tube, which receives rotation from the vertical shaft and transmits it to the horizontal one. On the latter, a propeller is installed, which will move the boat.

Sawmill

Several homemade sawmills using chainsaws have been invented. They are:

1. Stationary motionless. In them, the chainsaw is placed in a special machine and remains in place - a log moves towards it. Cutting quality is high; workpieces of any length can be cut. But the structure has a complex log feeding mechanism.
2. Stationary mobile. Option with rail guides along which the carriage moves with a fixed saw. The workpiece is motionless. The option is easier to operate, but the length of the logs is limited.
3. Mobile. The saw head moves along the log. It is not heavy and can be carried. The workpiece itself serves as a guide. The option is convenient for one-time work or a small amount of cutting. Requires a lot of effort to move the saw.

Moped

The procedure for converting a bicycle into a self-propelled unit is as follows:

1. Remove the cover and dismantle the tire from the motor housing.
2. A creeper is made in the form of a shaft, on which small and large sprockets from a bicycle are attached at different edges.
3. A small sprocket is installed on the engine output shaft, and a large sprocket is installed on the bicycle wheel, next to the existing one.
4. Mount the motor and creeper at the rear of the seat on an additional frame.
5. Chains are put on, connecting the smaller and larger sprockets at the engine with the creeper and at the latter with the bicycle wheel.
6. A lever is brought to the handle of the bicycle handlebar, which regulates the supply of gasoline in the power unit.

Snowmobile

For such a homemade product to easily move through the snow, one is not enough. You need more power - at least 2 chainsaws.

The manufacture of snowmobiles begins with the frame.

It should be light, therefore pipes made of aluminum alloys are used.

The shape of the frame is an isosceles, elongated triangle. In each corner of it, a vertical rack is attached, directed downward. Skis are placed on the free ends:

• in front with the possibility of turning with a bicycle handlebar;
• behind - irreversible, parallel to the longitudinal axis of the sled.

The motor from the chainsaw is attached to the base of the triangular frame - at the gearbox, the output shaft is directed backward parallel to the axis of the frame. An air propeller is also located on it. The transmission of rotation to the latter from the gearbox is provided by a chain drive.

The lever for regulating the fuel supply is placed on the steering wheel of the snowmobile. To accommodate the athlete, a light seat is provided within the front of the frame.

Tricycle

The easiest way to get it is from a tricycle, the conversion of which into a self-propelled tricycle is to equip it with a motor from a chainsaw. They do this in the same way as with the moped, which is described above.

If the bike is 2-wheeled, you will have to:

• remove the rear wheel;
• remake the rear of the frame, providing 2 forks for 2 wheels on it;
• arrange a common transverse shaft and install a sprocket on it for a chain drive from the motor.
