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

In the hands of craftsmen conventional chainsaw, originally intended for sawing wood, becomes truly multifunction device. At the same time, the breadth of its application is simply amazing in its diversity. On sale meet different kinds special nozzles that greatly expand the capabilities of chainsaws. These include the following attachments: a petrol cutter, a scorcher, a pump for pumping water, a motor, a brush cutter, a snow blower, and others. But, despite this, many craftsmen remake chainsaws on their own, using improvised materials. Do-it-yourself homemade chainsaws can be made by almost anyone who is more or less versed in technology.

The principle of rework

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

Realize the potential of a chainsaw with a variety of attachments and attachments. At the heart of any alteration is the simple principle of engine power take-off: a necessary for the master device. 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 the possibilities truly limitless. Equally important is the practical design of the clutch, which protects the components and systems of the saw from damage and overload. A 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 divided into 2 groups:

most simple devices(Bulgarian, ice drill, 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).

For the manufacture of all of the above devices, you can use various brands of chainsaws. When choosing them, one should take into account required power for normal operation alterations. Most often, for the manufacture of various devices, the following brands of chainsaws are used: Friendship, Calm, Ural.

The simplest homemade chainsaw

Below are various options devices made from chainsaws. Anyone can use these ideas in their household. From a chainsaw with a little additional materials can do:

Bulgarian. The main system of such a device is a bearing assembly with a shaft. At one end, a driven pulley is installed, which rotates with the help of a V-belt. On the other, a mandrel for cutting wheels is fixed. Depending on their brand, such a grinder can cut stone, metal, brick and other building materials.

ice drill. For good operation of the device, the screw speed should not be high, so it is necessary to use a gearbox made in the form of a worm or V-belt drive. 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 bracket to attach to the saw and a pulley that drives the pump turbines.

Winch, which uses a chainsaw drive. The traction force of such a device directly depends on the power of the saw motor. Using additional block it can be increased significantly. This device equipped with such additional details as a tap-off block, hooks, belts, anchors.

Outboard motor from a chainsaw- a great alternative to buying an expensive engine. To ensure movement of 20 km / h, it is enough to install a home-made outboard motor with a gearbox (gear ratio 2: 1) and a 3-bladed propeller with a diameter of 210 mm on the boat. At the same time, fuel consumption will be only 1 liter per hour of engine operation.

Motor cultivator almost anyone 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 for personal plot its power is sufficient.

Chainsaw moped. For such a vehicle, you will need a base, for example, old bicycle. A chainsaw motor is attached to its frame. As a rule, a gear 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:

Chainsaw sawmill, which can be done with metal frame. A chainsaw is rigidly attached to this frame. Workpieces can be guided along the rail track. There are other options for sawmills. So for a device designed for longitudinal sawing, you will need an adapter attached to the tire 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 sawn log. With the help of such a sawmill, logs can be divided into 2-4 parts.

Chainsaw portable power plant is able to provide energy in any places remote from the power grid. To create it, the following components are needed: 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 screw assembly through a pair of gears. You can attach both wheels and skids to the snow blower. Any large diameter pipe can be used to throw snow.

Homemade snowmobile from a chainsaw its design is a little more complicated than a sawmill. The snowmobile consists of a frame, engine, track and steering. He also needs skids for movement. To create it on the steering wheel, you need to take out the gas and clutch. You should also consider a shock-absorbing suspension system of 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. For the steering mechanism, you can use the parts of an old bicycle. It is being redesigned so that the central axis moves the turning skis of the thrust. To enhance traction, a traction gear is installed on the caterpillar drive shaft. Engine power must be at least 5 hp.

Snowmobile from a chainsaw much easier to make than a snowmobile. A large propeller driven directly by the chainsaw's engine provides the driving force. A serious limitation on the use of such snowmobiles due to their insufficient cross-country ability is the low power of the chainsaw engine. For trips on snowy fields, an engine with a power of at least 12 hp is required.

Helicopter knapsack type from a chainsaw. Such an aircraft can take to the air 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 from 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 furnace to 850°C. The blanks are pressed until they get rid of the voids between the links. Next, the metal is subjected to forging until the workpiece is given the required shape and strength.

What did you do with a chainsaw?

The chainsaw is very popular among home craftsmen, as it is a universal drive for original home-made designs.

Light weight and solid power, combined with compact dimensions, allows this "lumberjack's dream" to be aggregated with an ice drill and a bicycle, a sawmill and a winch.

Interesting homemade chainsaws can be made by anyone who confidently works with a welding machine, grinder, and, if necessary, can also stand up to a lathe.

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

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

Homemade options

The first thing that comes to mind when you think about what you can do with a chainsaw is its use as a sawmill. Many developers had to dissolve logs on a beam with this tool.

Holding the saw on weight in your hands is very difficult to control the accuracy of the entire length of the cut. Therefore, with a three or four-meter length of a log, it strongly moves away from the intended line. Solving this problem can be quite simple. To do this, the chainsaw is rigidly fixed on the frame, which moves along the guide profile.

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

A sawmill from 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 a saw band sawmill.

snowmobile

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

In addition, you need to develop yourself or use ready-made caterpillar drawings 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 V-ribbed 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 an ordinary bicycle or scooter and modified in such a way that the central axis moves the rods that turn the skis. The engine power of a snowmobile must be at least 5 horsepower, so it is better to use a Ural chainsaw for this purpose.

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

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

Those home inventors who would like to make a backpack-type helicopter out of 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, and not for 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 the old grandfather's Druzhba chainsaw and no less ancient bicycle, with which you can carry out any experiments on altering the frame for mounting the drive.

The power transmission here is carried out through a gear pair by means of 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. Such a moped from a chainsaw is equipped with a gearbox with a gear ratio of 18: 1 and a variable speed transmission, which allows you to comfortably ride it at the speed of a conventional 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. It will need to be done for lathe reliable adapter from the saw drive gear to the propeller shaft. The screw can be used from a standard outboard motor.

The photo shows a variant in which there is a gearbox in front of the propeller that changes the angle of rotation of the shaft by 90 degrees. In more simple models do without it, fixing the engine on the boat so that the shaft is immersed in 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 a light motor-cultivator based on it was able to build many home craftsmen.

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

snow blower

The chainsaw motor does not care what to rotate - cutting chain or snow blower auger mechanism. 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 cleaning the area from loose snow. To simplify the design, some craftsmen refuse to install wheels using conventional sled skids.

The most responsible part, on which depends how well homemade snow blower will do its job, is the screw 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

Under the snow thrower, you can adapt a plastic sewer pipe, fixing it on the body of the intake.

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, the “strength” of this tool for the development of airspace is not enough. Therefore, no one has yet succeeded in making a backpack 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 speed several times and work in a coordinated mode.

Motobur

This device is 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 drill operates at low speeds, in order to adapt the chainsaw motor, it is connected to the auger through a step-down 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 sawn tree.

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

Power station

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

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

A good owner will not throw away anything in vain, especially if we are talking about quality metal. If you understand the nuances heat treatment metal, you can do chain forged knife, which 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 petrol saw used for sawing wood. However, in times of total shortage, craftsmen adapted to use it as a drive for other machines and mechanisms. Homemade chainsaws can be made by anyone who understands mechanics and knows how to hold a tool in their hands. Thus, you can build an interesting and useful device in everyday life.

Useful items from a chainsaw

It all depends on the imagination of the master. From a chainsaw you can do:

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

A snowmobile is very simply made on the basis of a small bicycle. A ski is placed in front, a pair of ultra-low pressure wheels are placed on a solid axle at the back. Such a homemade saw “Friendship” or “Ural” will rather cheerfully run on ice or rolled snow.

For deeper loose snow, such a snowmobile model is unsuitable, the power of the saw engine is not enough. More versatile is a snowmobile that uses a caterpillar as a mover. 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 referred to as "stick insects".

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

Do-it-yourself bike with a chainsaw motor is the easiest to do. Any frame bike will work for this. The throttle control cable is displayed on the steering wheel. Chainsaw chains and bicycle chains have the same links, so no special gears are required. 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 decrease the speed. This is good, because a regular bike is not designed to ride at a speed of more than 20 kilometers per hour.

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

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

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

To build a homemade outboard motor from a chainsaw, a gearbox is not needed. It is only necessary to weld a frame with two clamps for mounting on the transom of the boat and install a propeller on the shaft. Those who made homemade products from a trimmer with their own hands can easily make a boat motor from a chainsaw.

You can also construct a simple snow blower from a chainsaw. To do this, you need to install the saw on the skids from the sled and add a homemade auger assembly. The guide for folding snow can be made from an ordinary sewer pipe.

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

Our hands are not for boredom

Chainsaw "Druzhba" is best used as an engine and drive for the following devices:

generator;
water pump;
sawmills;
circulars;
Bulgarians.

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

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

A similarity of a band sawmill is easily constructed from a chainsaw, where instead of the tape the carriage with the saw fixed on it will move. This design will allow you to dissolve the tree trunk onto a beam yourself. Theoretically, boards can also be sawn, but due to the wide cut, there will be big losses.

Technique on the verge of fantasy

In Soviet Union for a long time there was a story about a prisoner, who was able to fly away from the zone on a chainsaw made homemade helicopter . 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 chainsaw. synchronized in one block. Prototypes of these developments were repeatedly shown at various exhibitions. Despite this, such models were never mass-produced.

The dream of heaven for those who like to design something from chainsaws is still a dream. Nevertheless, attempts to make a backpack single-seat 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 you can do with your own hands. This article is written to help the masters and eliminate this gap.

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

popularity - the chainsaw was very popular during the Soviet era, because. there were simply no other saws, except perhaps the Urals.
cost - today in the secondary market, the price, depending on the condition, 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 such homemade products as a mower, helicopter, sawmill, all-terrain vehicle, motorized dog and others.

What do you need to work

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

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

What can be done from a chainsaw Druzhba

Technique that you can do with your own hands from has a large list. Everything is limited only by the imagination of the master. There are many videos on the Internet detailed description step by step manufacturing homemade. As part of the article, we have collected only the most best videos, on the basis of which you can easily make the technique you need. An outboard motor is considered the simplest homemade product, and an all-terrain vehicle, a motorized dog, a lawn mower is considered the most difficult. We give 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 sharpening very well and is resistant to corrosion. For manufacturing, only the tires themselves from the saw are required. The price in the secondary market varies from 200 to 500 rubles. To implement the craft, we suggest you look interesting video, the author of which describes in detail how to do kitchen knife from the 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.

A bike

To make a bike with an engine from a Druzhba chainsaw, you will need the saw itself and a bike, preferably a Kama with a trunk. The process of making homemade:

Attach the motor to the bike frame.
Lay the throttle cable and trigger on the steering wheel.
Connect the chain to the drive wheel of the bicycle and the pulley on the saw motor.

Mower (lawn mower)

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

boat motor

It will be much more difficult to convert a chainsaw into a boat motor than into a bicycle or a 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. Engine from Friendship 4. All that remains is to connect them together. For example, we recommend watching an interesting video, the author of which made an outboard 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 the longitudinal dissolution of the 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 the device in operation. From the video it becomes clear that a homemade product needs a minimum of materials - ordinary rolled metal (profile 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, the authors of which 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 the engine. The only recommendation is to use ordinary cameras connected around the perimeter instead of wheels, 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 homemade product uses a scooter, a goose, so this is most likely a snowmobile than an all-terrain vehicle.

Motodog (mototower)

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 motorized dog almost from improvised materials. For example, track lugs are made from conventional plastic pipes, and the entire frame of the motorized towing vehicle is welded from ordinary profile pipe small diameter.

Helicopter

Converting a chainsaw into a helicopter is most likely just an experiment, practical application no. There is a video on the Internet aircraft, the authors of which developed such projects and implemented them, for example, a home-made airplane from a chainsaw.

Conclusion

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

Homemade products 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 saw.

snowmobile

They begin work with the snowmobile frames and the caterpillar 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 that drives the caterpillars, in the rear - for its second axis, which is tension. Near the latter, on both sides, the frames are mounted tensioners for caterpillar and chain drive.

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

The rollers are suitable from the unit, which is used for sorting potatoes, the axles are from the potato digger. The axles are released, machined, threaded M10. Between the rollers, to fix the position, duralumin tubes of the appropriate diameter are placed.

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

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

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

A caterpillar for a motorized dog is used from Buran. It is shortened by 50 cm and sewn. Drive and tension gears are made in the form of "Buranovsky" from strong plastic 1.5 cm thick.

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

Flanges are welded to which gears are attached through holes.
The trunnion tips are pressed into the shaft holes, the diameter of which is previously 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 rotated. They fasten it with an M14 nut, under which the end of the trunnion is machined and threaded.

Similar to the drive shaft, but with 2 identical tips, they make a tension shaft.

The chainsaw engine is mounted through its frame on a motor subframe - a rack available on the cross beam. The fuel tank is located on top. The reducer is turned 180°, fixed on the platform. A creeper is also installed on it - an intermediate shaft. Sprockets with a number of teeth of 38 and 10 are attached to it. Chains for transmitting rotation are taken from the Voskhod, Minsk motorcycle.

V steering includes:

support-steering skis, on which levers are installed;
bipod of the steering shaft, with which the ski levers are connected by rigid rods;
motorcycle 2-lever steering wheel with a throttle control lever near the right handle.

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

snow blower

Homemade is simple, it is easy to do it yourself. First, a frame is made, which is welded from pipes of 3-4 cm 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.

The longitudinal elements of the frame serve to move the snow blower, being skids. Their ends are made oblique, the holes are welded to avoid clogging with snow. Crossbars are needed to accommodate the power unit.

The chainsaw motor is freed from the frame and redone:

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

Making a homemade snow blower auger:

For the shaft, an 80-85 cm piece of pipe of the same diameter is used as for the frame. In the center, 2 plates 13 cm long and 15 cm wide are welded on the sides. They are needed to eject snow.
From sheet metal 2-3 mm thick, 4 circles with a diameter of 30 cm are cut out. The inner parts are removed - disks with a diameter of 22-23 cm. The remaining circular elements are cut in one place and stretched, giving them the shape of springs.
Each pair of springs is placed symmetrically to the shaft, welded at one end to different parties central plates at their end portions. 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.
A metal case is made from sheet metal to accommodate the auger. It consists of 2 vertical sidewalls, in which the lower and front edges are straight, the rear is made in a circle. The latter is covered with a sheet of metal. The dimensions of the housing must ensure free placement inside the auger. The gap size is 5-7 cm.
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 snow removal use a segment (10 cm) aluminum pipe and a box that is 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. A box is bolted to the segment.

The housing in which the auger is installed is placed in front of the frame. The sidewalls are welded to the longitudinal pipes. The motor is fixed on the crossbars of the frame, placing the drive sprocket and the driven sprocket installed at the end of the screw 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 side of the auger housing).

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

boat motor

The saw set is removed from the chainsaw engine, the drive sprocket is removed. The coupling is redesigned by turning a smaller cup and replacing the tightening spring, which allows to reduce the mass of the assembly and reduce the adhesion force. The shaft of the motor and the gearbox are connected through the coupling.

For installation use a channel:

in the top shelf suit required holes for fastening the engine with a reducer;
the lower shelf is provided with a hole, a tube is welded into it coaxially with the output shaft of the gearbox.

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

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

sawmill

Several home-made sawmills using chainsaws have been invented. They are:

Stationary immovable. In them, the chainsaw is placed in a special machine and remains in place - a log moves towards it. The cutting quality is high, it is possible to cut workpieces of any length. But the design has a complex mechanism for feeding logs.
Stationary mobile. A variant with rail guides along which a carriage with a fixed saw moves. The workpiece is immovable. The option is easier to operate, but the length of the logs is limited.
Mobile. The sawing part moves along the log. It is lightweight and can be carried. The workpiece itself serves as a guide. The option is convenient for one-time work or a small amount of cut. Requires a lot of effort to move the saw device.

Moped

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

Remove the cover and dismantle the tire from the motor housing.
A creeper is made in the form of a shaft, on which small and large asterisks from a bicycle are attached at different edges.
They install a small sprocket on the output shaft of the engine, and a large sprocket on the bicycle wheel, next to the existing one.
Mount the motor and creeper behind the seat on an additional frame.
Chains are put on, connecting the smaller and larger sprockets at the engine with a creeper and at the latter with a bicycle wheel.
A lever is placed on 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. More power is needed - at least 2 chainsaws.

The manufacture of snowmobiles begins with the frame.

It should be light, because aluminum alloy pipes are used.

The shape of the frame is an isosceles, elongated triangle. In each of its corners are attached vertical stand pointing down. Skis are located at the free ends:

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

The chainsaw motor is attached to the base of the triangular frame - at the gearbox, the output shaft is directed back parallel to the frame axis. It also has air propeller. The transmission of rotation to the latter from the gearbox is provided by a chain transmission.

The lever for regulating the fuel supply is carried out 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 an engine from a chainsaw. They do this in the same way as with the moped described above.

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

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