8. A generator is for those who like to relax in nature in comfort.
9. A winch - it will help pull the car out of the mud in the forest.
10. Petrol cutter.

Need to know! Any of the equipment listed is easy to purchase in specialized stores, however, many readers will agree that making it yourself is much nicer and cheaper.

Let's look at these options in more detail.

Chainsaw snow blower: manufacturing features and necessary materials

Let's look at how to make a snow blower, from which (when making additional accessories for a chainsaw) summer period You can easily mount a walk-behind tractor.

Important! Even if the home craftsman has no experience in welding, if he has inverter device and some training on unnecessary metal parts This kind of work is quite doable.

To begin with, let’s take a step-by-step look at the manufacture of the main component of a snowblower – the auger, without which throwing away snow is not possible.

Illustration	Action to be performed
	The first thing you need to do is cut from sheet metal These are the preparations. The sheet thickness should not be less than 2 mm. The outer diameter is 300 mm, and the width work surface– 70 mm. You will need 4 such blanks: 2 on each side (the dimensions are given approximately, it all depends on what the auger casing will be made of). Afterwards they are welded (two at a time) and mounted on the shaft. The most labor-intensive work here can be called stretching the metal rings to the state of a screw (spiral).
	The two parts are mounted on the shaft in different directions, and “blades” are welded in the middle, which will throw out the snow. It is rational to make them from a metal pipe with a diameter of 100 mm. The gear for the chain drive can be taken from any old motorcycle (driven, from the rear wheel).
	Frame. You can make it yourself from sheet iron with a thickness of at least 1 mm, however, it is more convenient to use an old one for this purpose. gas cylinder or a barrel of fuel and lubricants.
	Please note that the casing and auger-rotor frame can be assembled using bolts. This saves the home craftsman from performing welding work after manufacturing the auger (in its manufacture, welding is indispensable).

The frame is assembled on runners or wheels - it all depends on the wishes of the home craftsman, but it is worth noting that the design on wheels is more maneuverable.

Expert opinion

Ask a specialist

“The higher the auger-rotor handle and the greater the angle of its inclination, the more the snow blower will dig into the snow. This should be taken into account during production. It would be better if the handle was adjustable in height and angle of inclination.”

All that remains is to install the engine and tension the chain (also from any faulty motorcycle). We invite you to familiarize yourself with sample drawings of such equipment.

How to make a snowmobile with your own hands from a chainsaw: nuances of the work

To make a snowmobile, you will need factory-made tracks, a brake or gas cable from a car, and a children's snow scooter. The main thing here is to correctly calculate the dimensions of the engine mounting frame. Let's try to figure out in detail how to make a snowmobile from a chainsaw.

Illustration	Action to be performed
	As you can see in the photo example, chain drive performed similarly to the previous option. To increase the power of the unit, we increase the driven sprocket, and for greater speed, we decrease it.
	The frame with the engine is attached to the children's snow scooter. By the way, if you install wide wheels instead of runners and attach a plow or cultivator to the back, you will get a full-fledged walk-behind tractor from a chainsaw.
	The chainsaw is installed on the frame without changing the design. Only the saw blade itself is removed.
	The cable is pulled from the gas supply of the chainsaw and secured together with the handle on the handlebars of the snow scooter.
	Such a chainsaw snowmobile (“Druzhba” is preferable to “Ural”) is capable, in addition to an adult, of carrying a load of up to 100 kg.

Is it possible to assemble a homemade sawmill from a chainsaw?

It's pretty simple. There is no need to remove anything from the saw itself. It is necessary to weld a stand on which the chainsaw will be mounted, with rollers (the unit will slide on the rails on them) and, in fact, install the rails themselves. You can see what the design looks like on next photo.

Important! All frame parts must be firmly fixed. The same applies to logs - you need to think about their fastening between the rails. Remember the safety rules. Failure to comply with them is dangerous to life and health.

Making a motor drill from a chainsaw with your own hands: how difficult is it?

In order to understand how to make an ice drill out of a chainsaw with your own hands, you need to understand the structure of the drive shaft, determine its dimensions and the attachment points of the drive gear. To make an adapter for the drill auger, you will need the services of a professional turner. Otherwise, there should be no problems with aligning the drill auger (no need for a handle).

DIY chainsaw ice drill diagrams

To make it easier for the reader to understand how the work is performed, we suggest that you familiarize yourself with several diagrams and photographic examples.

It is convenient to use a gearbox from an old hammer drill as a connector.

DIY boat motor from a chainsaw

The only difficulty here may be the manufacture of fasteners for the boat and installation of the gearbox. For a technically competent craftsman with an education, this will not be a problem, but for a beginning home craftsman it will be difficult. However, there is an alternative - purchase a screw with a gearbox in a specialized store, and contact a turner for an adapter. In any case, this will be cheaper than purchasing a factory-made boat motor assembled.

How to make a moped from a chainsaw and a bicycle: algorithm of actions

Illustration	Action to be performed
	First, remove the cover and dismantle the canvas. Next, you need to make a gear like this and weld it to the chainsaw disk. You should be careful - the sprocket must be fixed perfectly evenly. Otherwise, a chain falling off at high speeds can cause injury.
	We place the engine behind the seat. This is the most optimal place. The attachment to the bicycle frame must be strong. Pay attention to the location of the stars. On the rear wheel, in addition to the small one, there is also a large one. This is done to ensure that torque is transmitted evenly.
	Let's start testing. We pedal as if we were riding a bicycle normally. But we are tired and...
	... we start the engine, and the rear wheel begins to rotate with the help of the engine, the legs rest.
	Now all that remains is to install the gas handle on the steering wheel, and off you go - your DIY chainsaw moped is ready.

Not to say that it is simple, but there are no particular difficulties in this work. By simple calculations, you can understand that the maximum speed of such a vehicle is 113 km/h. However, it is worth understanding that a person sitting on it adds load, and the speed decreases. On average, 65 kg of weight will reduce it to 60 km/h. Therefore, the best option would be a moped from the Druzhba chainsaw, as it is more powerful compared to foreign analogues.

Assembling a go-kart from a chainsaw with your own hands: repeating what you have learned

The essence of the work is identical to the previous version, except that the engine is installed on a go-kart frame, and there is no need to mount a gearbox consisting of sprockets and two chains. Everything is much simpler here. If the dear reader has mastered the algorithm for creating a moped, there will be no questions about assembling the kart.

How to assemble a gasoline generator from a chainsaw with your own hands

This work is even simpler than all previous options. You just need to think about the frame on which the chainsaw will be mounted (without a blade), and the generator itself, as well as the belt drive. Here, not sprockets with a chain are used, but pulleys with a belt. In this case, you need to install the generator so that it can be adjusted to tighten the belt as necessary.

Chainsaw winch: manufacturing and applications

The areas of application of such a unit are very wide - from construction to pulling cars out of mud or a hole. To make it you will need:

• old hand winch;
• chainsaw;
• a rigid frame on which everything will be installed;
• two sprockets and a durable motorcycle chain to transmit torque from the saw motor to the gearbox.

Having become familiar with the structure of the snowmobile and the auger-rotor, it will not be difficult for the reader to imagine what such a unit should look like. But just in case, we will provide several photo examples below.

Making a DIY gas cutter from a chainsaw

A chain cutter or trimmer is what you can do with a Druzhba chainsaw if you have drawings, photographic examples and some free time. Such a unit will be useful not only for woodworking. By installing on it diamond blade, you can cut tiles, porcelain stoneware or paving slabs. Below are photos of the finished units. Such attachments for chainsaws are inexpensive, and you can purchase them at any specialized store.

Features of creating homemade products from a Ural chainsaw

Such saws are more suitable for powerful units - a sawmill, for example. However, despite the high power, it is clearly not worth installing a Ural engine on a bicycle to improve driving performance. The fact is that the increased power is compensated by strong vibration, which can lead to the chain falling off while driving. And this is fraught with trouble.

Helpful information! The undoubted advantage of "Ural" is that new device can still be found on store shelves today. This means that for newer models there will be no problems with service and spare parts. The main thing is that your hands are in place.

Features of making homemade products from the Druzhba chainsaw with your own hands

You can make any of the homemade items listed in our article today using the Druzhba chainsaw with your own hands. The vibrations of the engine are minimal, and if it is necessary to increase power, the gearbox can be upgraded. However, there is a significant disadvantage to “Druzhba” - the saw has been out of production for a long time, which means that difficulties may arise with maintenance and spare parts.

Considering the relatively low prices for chainsaws in Russian market, it would be more acceptable to use modern equipment for the purpose of making various homemade products.

Summarize

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

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

Initially, the main task of the saw is cutting wood. If you try, the device can be given greater functionality. Homemade chainsaws are amazing in variety. In addition to the fact that various attachments are available in retail establishments, such as an angle grinder, a grinder or a pump, many people use improvised means and create new devices. Thus, mopeds, snowmobiles, electric generators and other devices suitable for everyday use are made from chainsaws.

Even without using additional details A chainsaw is capable of performing a wide range of tasks. If to classic design By purchasing additional attachments, you will be able to expand the possibilities of using the device in the household and get the following devices:

• snow blower;
• brush cutter;
• pump for pumping water;
• petrol cutter;
• decanter.

Some craftsmen, armed with basic knowledge of mechanics, create additional accessories with your own hands for chainsaws, which can significantly expand the scope of the tool’s use. To remake it, you need to understand the operating principle of a universal motor drive, which is easy to use for the manufacture of other devices. Thus, taking a motor from a chainsaw, you can create the following devices:

• ice drill or drill;
• boat engine;
• a car or bicycle with a motor;
• lawnmower;
• generator.

The reason for the popularity of homemade chainsaws “Druzhba-4”, “Shtil” or “Ural” is a large number of advantages:

• powerful engine;
• light weight and compact dimensions;
• Possibility of use in extreme conditions.

This is interesting! Homemade products from a Ural chainsaw or devices of any other brand are valued due to the peculiarities of their operation and the ability of the tool’s clutch to protect components and important details from overloads due to overheating or other breakdowns. Also, the tightness of the motor makes it possible to use the device in any position.

Basic accessories for chainsaws that have gained popularity

If you purchase special attachments for the tool, it will be extremely easy to install them; you won’t need to modify anything or disassemble the tool body. All ready-made accessories are designed specifically for installation on a chainsaw. Another important advantage of purchasing a chainsaw is its autonomy. This is explained by the fact that everything electrical devices require a 220 V outlet. Using a chainsaw, you can use homemade products in field conditions, be it a drill, an ice drill or a wood cutter.

A do-it-yourself grinder attachment on a chainsaw allows you to use the equipment not only as a gas cutter, but also as a corner saw grinder. The nozzle is connected to the device via a special pin, and begins to rotate using a belt from a pulley attached to the drive sprocket shaft. Thus, the device is installed instead of the saw bar. It is important to choose the correct diameter of the nozzle circle; to do this, you must first study the instructions for the Druzhba chainsaw or other equipment used to make a useful device.

Important! Experts warn that it is not possible to install an adapter in all models to fit the bases.

Another common attachment among users is a corroder, used for cutting bark from trees. The attachment is also popular among woodworkers because it can be used to easily remove bark, knots and growths from untreated wood. Some people use a nozzle to create longitudinal or transverse grooves on the beam. There are mainly two types of coders:

1. Drums. The main area of ​​application is bark removal, the second name is decanter.
2. Disk. Used to create various kinds recesses.

There are several nozzles on sale that differ in grip width, most often 80 and 100 mm. If the knives become dull, there is the possibility of secondary sharpening. If the knives are completely out of order, it is better to purchase a new set from the manufacturer. The attachment itself is a cutter or drum mounted in a bearing assembly. Actuation is carried out by a belt drive, and the rotation speed is regulated by the force of pressing the accelerator handle. The diameter of the pulley also affects the speed: the larger it is, the higher the speed. Studs for installing the nozzle are included in the kit.

How to make a winch and sawmill from a chainsaw with your own hands

Homemade products from the Urals often help in construction. So, when constructing buildings from solid wood, it is necessary to dismantle the logs into beams. The sawmill from the Ural chainsaw makes it possible to perform this action as quickly and accurately as possible, while maintaining the accuracy of the cut. The main advantage is that there is no need to perform any complex alterations. The device just needs to be securely fastened in homemade frame, which can be made from metal corners or profile pipes. The log for processing is then placed on prepared guides.

You don’t have to create drawings for a sawmill using a chainsaw with your own hands, because a large number of ideas are available on the Internet that are suitable even for a person without experience.

The safety of using the structure is ensured by the fact that you do not need to move the log yourself. For this purpose, a carriage with a saw is used, which, depending on the thickness of the log, is fixed to required height. Once switched on, the frame moves precisely and the cut remains neat and even. You can use the device not only for solid timber, but also for sawing boards for the purpose of preparing firewood.

This is interesting! You need to be prepared for the fact that a large amount of sawdust will be formed during the work, since a chain of considerable thickness is used for sawing.

A homemade winch will also be a good helper during construction, because with its help you can easily lift loads to a height and move a cut tree. In addition, using a winch, you can pull out a stuck car or pull a boat out of the water onto the shore. The operating efficiency will depend on the gear ratio; in some models the figure can reach 1.5 tons.

To make the device convenient to use, you will need to make a durable frame using welding work. The motor, gearbox and drum with braking system should be firmly secured to the frame. To fix the frame on the body, holes and lugs should be provided through which the device can be installed on any surface.

How to create a lawn mower using improvised materials

To quickly deal with tall grass or tidy up the lawn, a lawn mower must be among the owner’s tools. You can purchase an ordinary factory version of the equipment, which is convenient to use, but you should keep in mind that the price of the lawn mower will be significant. A homemade “Friendship” chainsaw made by yourself will cost one and a half times less than a factory device, and the power is quite enough for standard household use.

Regardless of the type of design chosen, the trimmer will consist of a drive, frame, control system and knives. For ease of operation, the device is additionally equipped with wheels, legs, handles and a protective casing in which the mowed grass is collected. The process of making a lawn mower begins with creating a frame convenient size, most often made of metal corners. The optimal size is 25x25 cm. In general, the progress of work on the manufacture of equipment looks like this:

1. Using bolts, iron handles are attached to the finished frame, and wheels are mounted on the side parts.
2. Having previously studied the characteristics of the Ural chainsaw or any other model, remove the handle and tire from the device.
3. Using studs and nuts, the remaining part of the equipment is attached to the base. This must be done so that the gearbox shaft, rotated 90˚, looks down.
4. On next stage you will need to lengthen the gas cable, and use two tubes to make a sliding shaft connected to the gearbox.

Helpful advice! Some people make blades to build their own lawnmower, for example from parts hand saw. Much easier to purchase ready product, which is then using bolts or welding machine connects to the shaft.

Elements from old baby strollers or wheelbarrows are used as wheels. If you use several pipes of different diameters for manufacturing, you will be able to make a device with a telescopic operating system that can change the length.

This is especially important if the device is often used by people of different sizes. Also, creating a telescopic shaft will help regulate the height of the grass after the lawn mower passes. To ensure that the device lasts longer, does not fail after encountering hard stones, and effectively fights small bushes, it should be equipped with high-quality steel knives. For convenient use, it is recommended to additionally equip the mower with a grass catcher so that you do not have to collect the remains of the mown grass.

Do-it-yourself motor cultivator, snow blower, ice auger and drill bit

A chainsaw motor is also perfect for creating a motorized cultivator designed for plowing virgin soil (for light soils). To work with dense and wet soils, the power and torque of the engine most likely will not be enough, but for loosening the surface layer and removing the roots of weeds remaining in the ground, a cultivator using a chainsaw will be enough. The main part of the device is a rotating cutter, due to which the equipment moves around the site.

If you replace the shaft with plowshares in the cultivator with an auger, and also equip the structure with an intake device and a pipe for throwing away snow, the cultivator turns into snow blower. A motor from any saw with a power of 3-5 horsepower will be more than enough to clear loose snow on the site. It is only important to make a convenient screw mechanism. For this purpose, blades made of thick rubber are most often used. Parts made of galvanized steel are suitable as an intake device. Snow removal is easy to do by installing a large diameter plastic pipe.

Drill through ice or frozen ground hand tools– a rather long and physically difficult task. Making a motor drill with your own hands will greatly simplify this task. In this case, in addition to the motor, it is necessary to have a gearbox that regulates the number of revolutions per minute, because the device does not require such strong rotation as a chainsaw.

Helpful advice! If you do not have enough knowledge regarding the operation of the gearbox, you can seek help from an engineer who will help you choose the right mechanism. The required type of device is selected depending on the characteristics of the motor.

To create a motorcycle or ice drill with your own hands, the first thing you need to do is make a reliable housing, which is a truncated pyramid consisting of two rectangles of different sizes. You will need a grinder, a welding machine and metal pipes. It is inside this frame that the gearbox will be installed; accordingly, the dimensions of the housing will directly depend on the size of the gearbox.

For reliability, experts recommend using a part from a good motor drill made of durable steel as an auger, because low-quality material will not withstand heavy loads. Another important question is reliable fastening drill, which can be done using an ordinary pipe, fixed on both sides with dowels or studs. This method of fastening will allow you to change drills or use other devices for work.

Homemade chainsaws: boat motor and other vehicles

Chainsaw boat engines were first used during World War II in South-East Asia, because the saws themselves were several times cheaper than the motors. At first, bamboo sticks were used to secure the shaft, which were replaced with new ones as they wore out. In order to make a homemade product from a Calm chainsaw, you need to remove the tire from the device, and in its place install either a ready-made boat propeller or a homemade one. To perform the mounting, you will need to purchase a special adapter.

Then homemade motor for a boat from a chainsaw, it is fixed on the rear side of the boat so that the propeller is immersed in the water at a certain angle. In some cases, a gearbox is used instead of an adapter. By and large this is homemade design counts economical option, allowing you to speed up movement along the water surface, which is especially important for fishermen or hunters. The motor provides good running small boat and at the same time it is economical.

Helpful advice! Not all saw models are designed for long and continuous operation. Therefore, it is important to monitor the degree of heating of the device and turn it off in time to allow it to cool.

Design features of a snowmobile and snowmobile

A chainsaw snowmobile is considered one of the most difficult homemade devices, because its manufacture will require a large number of additional parts, including:

• frame;
• frame;
• tracks and front skis;
• steering wheel;
• control consisting of a handle and a clutch.

There is another difficulty. In order for a snowmobile to move, it needs to be equipped with suspension and transmission, so it will not be easy for a beginner to cope with such work.

Creating a snowmobile from a chainsaw with your own hands begins with a supporting frame, which is steel profile measuring 20x20 or 20x30 cm. A swing arm is responsible for shock absorption of the rear suspension, and a motorcycle-type steering fork is responsible for the front suspension.

This is interesting! More complex design consists of two skis, the steering wheel can not only turn the axis, but also pull the steering linkage levers. Despite the fact that this method is technically more complex, it provides more convenient control.

Additionally, a do-it-yourself snow scooter with a motor is complemented by a centrifugal clutch with a V-belt and chain. To enhance the traction force, a gear is attached to the caterpillar shaft, the diameter of which exceeds the drive part of the chainsaw shaft. For normal use homemade device you need to take a motor with a power of at least ten horsepower.

More simple option are snowmobiles that have a similar method of use, but are a propeller-driven aircraft moving through the snow. Due to the simplified design, the sled does not have a large load capacity, maneuverability and stability. Main advantages - simple design and ease of manufacture. The rotating screw installed behind the driver must be closed using protective casing, made of fine mesh. Control is carried out by turning the skis, the gas lever and the brake. Optimal power The engine is considered to be 5-6 horsepower.

How to make a moped from a chainsaw or a bicycle with a motor

A homemade moped made from a chainsaw is unlikely to compare with industrial version device, but as a kind of adult toys it will do just fine. By and large, the device is not a moped, but a bicycle with a chainsaw engine. This is due to the fact that it is most often used old frame from this vehicle.

This is interesting! More advanced craftsmen do not take a ready-made frame from an old bicycle, but make it themselves for this purpose welded structure from metal pipes or square profile. But the main components, including bearings, prefer to use factory ones.

Before installing a chainsaw engine on a bicycle, you should ensure that you have parts, such as:

• frame;
• engine with gas tank;
• gearbox with gear ratio 18:1;
• shock absorbers;
• brakes

Any engine for a bicycle from a chainsaw must be supplemented with a gearbox so that it is possible to regulate the rotation of the wheels. Sometimes, instead of a gearbox, gear pairs are used, connected to each other by a chain from a bicycle. If we take as a basis mountain option bicycle, then a gearbox with a gear ratio of 1:15 or 1:20, supplemented by a variator, is more suitable here. The main advantage of a mountain bike with a chainsaw motor is that, unlike a conventional device, it can be accelerated to 30 km/h.

Another simple vehicle to use is a chainsaw kart, which resembles a simplified model of a car, which is used mainly for circuit racing. The device does not have a solid body and does not have shock absorbers. The minimum number of parts makes it possible to lighten the design and provide it with greater speed of movement.

The frame is most often welded independently from a metal profile, and old carts are used as a wheel donor. A bicycle chain is used as a drive for the rear axle, and you will also need a steering linkage. To assemble the housing, you will need to use a welding machine. Some people consider a homemade kart to be a children's car with gasoline engine, but you need to take into account that the vehicle is capable of developing a decent speed.

What other homemade things can you make with a chainsaw?

The motor from a chainsaw can be used to independently move almost any vehicle. So, you can equip a children's or adult scooter with a drive, which can accelerate to a speed of 10-15 km/h. The main advantages of using a scooter are high maneuverability and no need for large storage space. Moreover, for production you do not have to disassemble the chainsaw into parts. You only need to remove the tire and saw chain, which is replaced by a bicycle one and serves as a part that transmits torque to the rear wheel.

In addition to making vehicles, using some saw parts, you can create a small mobile power station that reaches a power of 5 kW. To create a generator, a chainsaw will require a motor, a steel frame, an electrical distribution box with connected sockets, and a gearbox through which torque will be supplied to the generator shaft.

Some homemade products made from chainsaw chains are popular among farriers; for example, some create solid forged knives. To do this, the chain is divided into pieces, from which the bases of the blades are then welded by heating them to 850 °C. The molten chain is pressed until there are no voids between the links.

To create homemade chainsaws, you need to know the basics of simple mechanics, because you need to correctly connect all the elements together. You should not purchase an expensive tool for the invention; budget models of chainsaws are also suitable for this. When purchasing, you must take into account that the saw must be easy to disassemble, and parts for it must be available for sale. To make devices, it is better to take ready-made drawings, especially if you have no previous experience in creating homemade devices.

Do-it-yourself homemade chainsaws are best option manufacturing useful units that will help quickly solve a lot of everyday household problems. To create them, you can use scrap materials and old working equipment, which makes it possible to save a considerable amount of money and, at the same time, find a use for accumulated devices.

What can you make from a chainsaw with your own hands?

There is a considerable list of all kinds of homemade chainsaws that you can build yourself at home. Each of these units will bring a lot of benefits to the household and help save the energy and time of its owner.

Homemade sawmill

To make this homemade chainsaw you will need several steel pipes, which are connected to each other by welding, the guide and the saw itself. A ready-made sawmill will help you prepare a large number of boards for repair or construction.

Snowmobile with chainsaw engine

This homemade chainsaw consists of a durable steel frame, steering wheel, movement elements, a seat and, in fact, a motor and gearbox. A homemade snowmobile can accelerate to 15 km/h and can support 1 adult passenger with small luggage.

Chainsaw moped

This homemade chainsaw is a full-fledged motorbike, which differs from modern analogues in its simplicity of design and modest fuel consumption. The finished unit with a full tank can transport one adult passenger over a distance of 5 km.

Homemade ice screw

This simple homemade product from a chainsaw allows you to quickly drill holes in the ice for winter fishing, as well as make holes for installation pile foundation. In addition to the engine, to make an ice drill you will need a reduction gearbox, a durable auger mechanism and steel knives.

boat motor

This homemade chainsaw will help out during summer fishing on large lakes and rivers with strong currents. To make it you will need a screw mechanism and blades made of of stainless steel. The homemade boat motor is capable of transporting one adult passenger with a small load, reaching speeds of up to 20 km/h.

Homemade chainsaws have been around for many years. main theme for domestic craftsmen. The devices they created help facilitate many household chores. In addition, they save the family budget.

Generator

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

Order of operations:

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

Winch

The mechanism is designed for horizontal movement or lifting loads to a height. Does not depend on the availability of electricity, can be used outdoors, on hiking trips.

In order for it to have sufficient traction, you will need a Druzhba, Ural or other brand of chainsaw.

A prerequisite for this is that the engine power of a do-it-yourself chainsaw winch should not be less than 2.5 kW.

An important element of the device is the drum - you can make it yourself or use it from manual winch. In addition, you will need:

• gearbox to reduce the speed of the chain saw;
• metal pipes or rolled profiles, levers, cam clamps, clamps.

The procedure for making a winch:

1. A rigid frame is made from pipes. Welding is used.
2. Attach the chainsaw motor to it. The gearbox is connected to it with clamps, and the drum is connected to the output shaft of the latter.
3. Install a lever equipped with cam clamps connected to the drum shaft. This control element allows you to control the work process: when you move the lever in one direction, the drum rotates, and in the other, it stops.
4. An anchor is made with which the winch will be secured in the soil or cling to any stationary object. Use pointed corners that are welded or hinged to the frame.
5. A cable is wound onto a drum, the free end of which is equipped with a hook. It is used to capture and attach to a load that needs to be moved.

The device exists in 2 versions. Do-it-yourself chainsaw drills are made for the ground or for drilling ice. In the first case, the device facilitates the construction of deep holes for poles, fence supports, and other structures. In the second, he helps fishermen drill holes in winter. They differ in the drill used.

Craftsmen do not always use a chainsaw for its intended purpose; it usually serves as a powerful drive in various mechanisms. The ingenuity of our craftsmen has given rise to numerous and very diverse homemade chainsaws, surprising in their originality.

The advantage of a chainsaw as a drive is its compactness, low weight and high power. Any craftsman who is capable of turning a part can perform metalwork, use a grinder and a welding machine, and can make interesting designs based on a chainsaw.

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

What homemade chainsaw products have already been invented?

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

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

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

Chainsaw-winter transport

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

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

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

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

Homemade chainsaw - the engine is large

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

It is taken as a basis old bike, which is not a pity, and the well-known chainsaw “Friendship”. The transmission of force to the wheel is carried out using bicycle chain and a gear pair.

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

Boat engine

This design is simple to implement; a boat motor does not need a transmission; you just need to machine an adapter that will transmit torque from the saw drive gear to a standard boat propeller shaft and propeller.

Usually, either homemade engine they are mounted on the boat so that the propeller shaft is immersed in the water at a slight angle, or they are not too lazy to assemble a gearbox that transmits the rotation of the shaft at a right angle to the propeller.

Motor cultivator made from a chainsaw

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

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

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

Chainsaw based helicopter

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

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

Chainsaw winch

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

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

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

The talents of home craftsmen led to the emergence large quantity various equipment, the engine of which is a chainsaw.
