What can be made from a chainsaw: photos, videos, homemade devices

Remember the famous film with the brutal Mel Gibson? In a post-apocalyptic world, people fight for water, fighting with incredible equipment and using homemade mechanics to survive. You can bet that most of this was powered by gasoline engines, since they are the only fully autonomous equipment. And in the real world, this tool is in the arsenal of almost every summer resident. If you have a chainsaw, you will not be lost in any situation. In this material, the editors of the online magazine HomeMyHome.ru have prepared for you a review of homemade chainsaws. With your own hands, using simple devices, you can make many useful devices for the household on the basis of “Druzhba” or “Ural”.

Don’t rush to get rid of the “old lady” chainsaw, you will still need it!

What can be made from a chainsaw: 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 all electrical devices require a 220 V outlet. Using a chainsaw, you will be able to use homemade products in the field, be it a drill, an ice drill or a wood cutter.

A self-installed grinder attachment on a chainsaw allows you to use the equipment not only as a gas cutter, but also as an angle 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.

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

The cutter is one of the most popular chainsaw attachments.

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:

Drums. The main area of application is bark removal, the second name is decanter.
Disk. Used to create various types of 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.

Generator

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

Order of operations:

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

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 simply needs to be securely fastened in a homemade frame, which can be made of metal corners or profile pipes. The log for processing is then placed on prepared guides.

Scheme for making a sawmill from a chainsaw with your own hands.

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 at the 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 harvesting firewood.

On a note! 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.

A chainsaw sawmill will allow you to easily and quickly turn logs into timber.

To make the device convenient to use, you will need to make a durable frame using welding. 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.

rework principle

The basis of almost any homemade product is a chainsaw, using it as a universal drive that can be used for a huge number of different devices.
The area of their use is very wide: cutting stone and metal, pumping water, cleaning drilling, snow wells and holes, driving, moving various objects, swimming and even flying. Potential chainsaws realize their capabilities using a variety of attachments and accessories. The basis of any modification is the principle of a simple engine power take-off: the device necessary for the master is connected to the output shaft. The presence of a powerful motor, compact dimensions and relatively light weight of this tool, autonomy and the ability to work in extreme conditions make its capabilities truly limitless.

Of no small importance is the practical coupling design of the clutch, which protects the components and saws of the system from breakdowns and overload. A tool made from chainsaws is distinguished by its tightness, so it can be used in almost any position

How to make 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 of a convenient size, most often made of metal corners. The optimal size is 25x25 cm.

In general, the progress of work on the production of equipment looks like this:

Using bolts, iron handles are attached to the finished frame, and wheels are mounted on the side parts.
Having previously studied the characteristics of the Ural chainsaw or any other model, remove the handle and tire from the device.
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.
At the next stage, you will need to lengthen the gas cable, and use two tubes to make a sliding shaft connected to the gearbox.

A lawn mower made from a chainsaw will cost much less than a purchased one.
On a note! Some people make their own lawn mower blades, for example from parts from a handsaw. It is much easier to purchase a finished product, which is then connected to the shaft using bolts or a welding machine.

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.

Circular

There are two sawmill options. They differ in the vertical or horizontal arrangement of the working tool.

The device with a vertical chainsaw position contains:

A guide made from a section of channel or rectangular profile pipe. Its length should be greater than the size of the logs being processed.
Sled. For production, use 2 pieces (40 cm each) of a 50x50 corner. They are welded at the ends of the upper shelves perpendicularly to 2 metal strips 3 mm thick. The distance between the inner surfaces of the vertical shelves of the corners must correspond to the size of the channel or pipe.

In the middle of each corner, identical vertical plates with coaxial holes are welded on top.
A steel rod is inserted into them, welded perpendicular to the chainsaw bar. Pipe sections are placed on the rod on both sides of one of the vertical corners. The latter are fixed with M8 bolts through the corresponding threaded holes. They serve to set the thickness of the resulting boards.

To operate the circular:

A guide is placed on top of the log and secured to it with self-tapping screws that have countersunk heads.
Installed on the slide guide.
Turn on the chainsaw engine and move it along with the sled along the log.

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.

Drawing of a snow blower made by hand using a chainsaw.

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 a snowblower. 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.

Drilling through ice or frozen ground with hand tools is a rather long and physically demanding 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.

On a note! 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.

Chainsaw brownies will become indispensable assistants on the farm.

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 issue is reliable fastening of the 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.

Motor drill

During the construction season, a motorized drill made from a chainsaw will do an excellent job of digging holes for posts or screwing in screw piles, and in winter it will delight ice fishing enthusiasts. The design of a homemade motor drill will require a speed reduction gearbox, since piles should be drilled and screwed at a speed of 30-60 revolutions per minute. It is better to take the auger from a ready-made motor drill made of good steel. An auger for a hand drill or a homemade one made of simple structural steel will not last long with active use.

What can be made from a chainsaw: a homemade boat motor and other means of transportation

Boat motors made from chainsaws first began to be used during the Second World War in Southeast 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 a homemade motor for a boat made from a chainsaw is attached to 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, such a homemade design is considered an economical option that allows you to speed up movement across the water surface, which is especially important for fishermen or hunters. The motor provides good speed for a small boat and is also economical.

Even a beginner can make a homemade boat motor from a chainsaw.

On a note! 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.

Let's start attaching the drill

Of course, like the engine, the drill must be firmly fixed. But it's much easier to do. To attach it, you can take a pipe and connect the gearbox and drill with such a pipe, and then fix these connections. The big advantage of this design is that the drill can be replaced if necessary (for example, you may need to drill a hole of a different size).

You can try to make an “advanced” drill, which will have the ability not only for horizontal, but also for vertical drilling. To do this, you need another frame (made of a metal pipe) with a welded piece of vertical pipe.

More metal rings need to be welded to the body, which was made first. These rings must fit onto the vertical pipe without gaps. Now the entire updated structure is put on the drill pipe. You can start drilling.

There are two advantages to such an “advanced” drill: firstly, vertical drilling becomes possible, and secondly, drilling becomes much more convenient. However, there are also two disadvantages: firstly, it becomes heavier, and secondly, when drilling very deep, the drill pipe will interfere.

You can get rid of the second disadvantage if you make a drill guide pipe from parts that slide out from one another. Of course, these parts should not have a gap, but they should move within each other. Yes, and the structure will become even heavier.

You can also make it so that you can drill at a given angle. But the need for such drilling arises so rarely that it is better not to think specifically about this problem.

Design features of a snowmobile and snowmobile

A snowmobile made from a chainsaw is considered one of the most complex home-made 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 a steel profile measuring 20x20 or 20x30 cm. A swing arm is responsible for damping the rear suspension, and a motorcycle-type steering fork is responsible for the front suspension.

To make a snowmobile from a chainsaw, you will need to purchase many additional parts.

On a note! A more complex design consists of two skis; with the steering wheel it will be possible not only to turn the axis, but also to pull the levers of the steering linkage. 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 operation of a homemade device, you need to take a motor with a power of at least ten horsepower.

A simpler option is the snowmobile, which has a similar method of use, but is 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. The main advantages are simple design and ease of manufacture. The rotating propeller, installed behind the driver's back, must be covered with a protective casing made of fine mesh. Control is carried out by turning the skis, the gas lever and the brake. The optimal engine power is considered to be 5-6 horsepower.

Application of cultivators

Since cultivating even a small plot of land requires a lot of effort, summer residents are thinking about making a motorized hoe. These workers come to the idea of making a homemade walk-behind tractor with their own hands because factory-made walk-behind cultivators are expensive.

Homemade walk-behind tractors are used to carry out the following procedures:

plowing;
hilling,
mowing,
application of fertilizers.

Also, a do-it-yourself motorized plow will help with snow removal and weeding, and if you add a trailer, you can use it to transport cargo weighing up to 200 kg. A light walk-behind tractor usually includes only a cutter and a weeder. On a medium-weight product you can find a milling cutter, a plow, a mower and a hiller. Heavy products are reliable, have high maneuverability and non-removable wheels. With this design of the walk-behind tractor, it is possible to use the following equipment:

cutter;
plow;
harrow;
rake;
mower;
semitrailer;
snow blower.

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 the industrial version of the device, but it is quite suitable as a kind of adult toy. By and large, the device is not a moped, but a bicycle with a chainsaw engine. This is due to the fact that most often it is the old frame from this vehicle that is used.

A moped using a chainsaw can accelerate to 30 km/h.

On a note! More advanced craftsmen do not take a ready-made frame from an old bicycle, but independently make a welded structure for this purpose from metal pipes or a 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 a mountain bike as a basis, 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.

For a bicycle you need not only a chainsaw engine, but also a gearbox.

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 home-made kart to be a children's car with a gasoline engine, but you need to keep in mind that the vehicle is capable of developing a decent speed.

Scooter

For improvement, a scooter that has inflatable wheels and a hand brake is better suited. The first allows it to move over uneven surfaces, the second provides high braking ability.

Perform work in the following sequence:

The chain and bar are removed from the chainsaw.
Unscrew the centrifugal clutch from the crankshaft.
Bicycle sprockets are attached to the output shaft of the engine and the axle of the rear wheel of the scooter.
Place the motor at the back of the scooter platform. They are connected to each other with bolts. Both sprockets must be in the same plane.
Put a bicycle chain on the sprockets, adjust it, removing excess links.
Attach the accelerator to one of the handles of the scooter. Connect it to wires that turn the motor on/off. Instead of an accelerator, you can install a small pedal.

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. It will be necessary to remove only the tire and saw chain, which is replaced by a bicycle chain 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.

Quite often chainsaw chains are used in their work by forging.

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.

Where do you need to start?

If you have a very small plot, it is not justified for you to buy an expensive walk-behind tractor. In addition, such equipment requires careful maintenance, the purchase of additional lubricants, fuel and parts. If you have a chainsaw, you can easily upgrade it.

The chainsaw has compact dimensions, light weight, but at the same time quite high power. That is why it can act as a universal drive to create a walk-behind tractor for cultivating the land.

The entire stage of converting a chainsaw into a walk-behind tractor takes place in several stages:

creating a drawing. Without this, you will not be able to make truly high-quality equipment. On the diagram you should indicate all the parts, their attachment points, and clearly calculate the dimensions;
frame manufacturing. It should be made of a cube with angles of 32 by 32 millimeters;
the motor is mounted on the transverse upper frame corners, and the fuel tank is mounted slightly lower using brackets;
in front there are also vertical posts needed for intermediate shaft supports. To mount the bearings, you need to install special supports at the longitudinal corners.
