Homemade chainsaws: how to make useful inventions
Initially, the main task of the saw is sawing wood. If you try, you can give the device more functionality. Homemade chainsaws amaze with their variety. In addition to the fact that various nozzles are available in retail establishments, such as a grinder, a cracker or a pump, many use improvised means and create new devices. So, mopeds, snowmobiles, electric generators and other devices suitable for everyday life are made from chainsaws.
What kind of homemade products can be made from a chainsaw “Friendship” and other devices
Even without the use of additional parts, the chainsaw is capable of performing a wide range of tasks. If you purchase additional attachments to the classic design, you will be able to expand the possibilities of using the device on the farm and get such devices:
- brush cutter;
- pump for pumping water;
- the cigarette lighter.
Some craftsmen, armed with elementary knowledge of mechanics, create additional devices with their own hands for chainsaws, which can significantly expand the boundaries of the use of the tool. To redo it, it is necessary to understand the principle of operation of a universal motor drive, which is easy to use for the manufacture of other devices. Thus, taking the motor from the chainsaw, it will be possible to create such devices:
- ice drill or buroyam;
- boat motor;
- a typewriter or a bicycle with a motor;
- lawn mower;
The reason for the popularity of homemade chainsaws “Druzhba-4”, “Calm” or “Ural” is a large number of advantages:
- powerful engine;
- small weight and compact size;
- the possibility of use in extreme conditions.
It’s interesting! Homemade chainsaws from the Ural chainsaw or devices of any other brand are appreciated due to the peculiarities of operation and the ability of the clutch of the tool to protect nodes and important parts from overloads due to overheating or other breakdowns. Also, the tightness of the motor makes it possible to use the device in any position.
The main devices for chainsaws that have gained popularity
If you purchase special nozzles for the tool, then it will be extremely easy to install them, for this you will not need to redo anything or disassemble the tool body. All ready-made devices are designed specifically for installation on a chainsaw. Another important advantage of purchasing a chainsaw is its autonomy. This is because all electrical devices require a 220 V outlet. Using a chainsaw, you will be able to use homemade tools in the field, whether it is a drill, an ice drill or a cracker.
A self-installed grinder attachment for a chainsaw allows you to operate the equipment not only as a gasoline cutter, but also as an angle grinder. The nozzle is connected to the device by means of a special stud, and begins to rotate using a belt from a pulley attached to the shaft of the drive sprocket. Thus, the device is installed instead of a saw tire. It is important to choose the correct diameter of the nozzle circle, for this you need to first study the instructions of 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 plinths.
Another common attachment among users is a bark cutter, used for cutting bark from trees. Also, the nozzle is popular with carpenters, because with its help it is easy to clean the untreated forest from bark, knots and growths. Some use a nozzle to create longitudinal or transverse grooves on the beam. Basically , there are two types of scavengers:
There are several nozzles on sale that differ in the width of the grip, more often it is 80 and 100 mm. In case of blunt knives, there is a possibility of secondary sharpening. If the knives are completely out of order, it is better to purchase a new manufacturer’s kit. The nozzle itself is a milling cutter or drum fixed in the bearing assembly. Actuation is carried out by means of a belt drive, and the rotation speed is regulated by pressing the accelerator handle. The speed is also affected by the diameter of the pulley: the larger it is, the higher the speed. Studs for installing the nozzle are included.
How to make a winch and a chainsaw sawmill with your own hands
Homemade products from the “Urals” often help in construction. So, when erecting buildings from a solid forest, it is necessary to dissolve logs on a beam. The chainsaw sawmill “Ural” makes it possible to perform this action as quickly as possible, accurately, 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 fixed in a homemade frame, which can be made of metal corners or profile pipes. The log for processing is then laid on the prepared guides.
You will not have to create drawings of a chainsaw sawmill with your own hands, because a large number of ideas are available online, 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 serves, which, depending on the thickness of the log, is fixed at the required height. After switching on, the frame moves precisely, and the cut remains neat and turns out smooth. It is possible to operate the device not only for solid timber, but also for sawing boards, for the purpose of harvesting firewood.
It’s 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 it will be easy to lift loads to a height, move a sawn tree. In addition, using a winch, it will be possible to pull out a stuck car or pull a boat out of the water to shore. The efficiency of the work will depend on the gear ratio of the gearbox, in some models the indicator can reach 1.5 tons.
To make the device convenient to use, you will need to make a solid frame using welding work. The motor, gearbox and drum with braking system should be firmly fixed on the frame. To fix the frame on the housing, holes and eyelets should be provided through which the device can be installed on any surface.
How to create a lawn mower using improvised tools
In order to cope with the tall grass faster or put the lawn in order, a lawn mower must be present among the owner’s tools. You can purchase an ordinary factory version of the equipment, convenient to use, but keep in mind that the price of the lawn mower will be significant. Handmade homemade chainsaw “Friendship” will cost one and a half times cheaper than the factory device, and the power is enough for standard household use.
Regardless of the chosen type of construction, the trimmer will consist of a drive, a frame, a control system and knives. For ease of operation, the device is additionally equipped with wheels, legs, handles and a protective casing in which the mown grass is collected. The process of making a lawn mower begins with the creation of a frame of a convenient size, most often made of metal corners. The optimal size is 25 × 25 cm. In general , the progress of work on the manufacture of equipment looks like this:
Useful advice! Some produce knives to create a lawn mower on their own, for example, from parts of a hand saw. 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 several pipes of different diameters are used for manufacturing, it will be possible to make a device with a telescopic system of operation capable of changing the length.
This is especially important if the device is often used by people of different complexions. Also, the creation of a telescopic shaft will help to adjust the height of the grass after passing the lawn mower. In order for the device to last longer, not to fail after meeting with hard stones and to fight qualitatively with small bushes, it should be equipped with high-quality steel knives. For convenient use, it is advised to additionally equip the mower with a grass collector so that you do not have to collect the remains of the mown grass.
A motorcycle cultivator, a snow plow, an ice drill and a drill with your own hands
A chainsaw motor is also perfect for creating a motor cultivator designed for plowing virgin land (for light soils). To work with dense and moist soils, the power and torque of the engine will most likely not be enough, but it will be enough to loosen the surface layer and remove the remaining roots of the weeds of the cultivator from the chainsaw. The main part of the device is a rotating milling cutter, due to which the movement of equipment on the site takes place.
If the cultivator replaces the shaft with ploughshares with an auger, and also equips the structure with a fence device and a pipe for throwing snow, the cultivator turns into a snowplow. The motor from any saw with a capacity of 3-5 horsepower will be more than enough to clean loose snow on the site. It is only important to perform a convenient screw mechanism. For this purpose, blades made of thick rubber are most often used. Galvanized steel parts are suitable as a fence device. Snow ejection is easy to implement by installing a large diameter plastic pipe.
Drilling ice or frozen ground with a hand tool is quite a long and physically difficult task. Creating a motorcycle holster 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 need such a strong rotation as a chainsaw.
Useful advice! If there is not enough knowledge about the operation of the gearbox, you can ask for 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 to make a reliable body, 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, respectively, the dimensions of the housing will directly depend on the size of the gearbox.
For reliability, experts recommend taking a part from a good motor drill made of durable steel as a screw, because low-quality material will not withstand heavy loads. Another important issue is the reliable fastening of the drill, which can be carried out 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: outboard motor and other means of transportation
Outboard motors from chainsaws were first used during the Second World War in Southeast Asia, because the saws themselves were several times cheaper than motors. At first, bamboo sticks were used to attach the shaft, which were replaced with new ones as they wore out. In order to make a homemade chainsaw “Calm”, you need to remove the tire from the device, and install either a ready-made boat screw or a homemade one in its place. To perform the fastening, you will need to purchase a special adapter.
Then a homemade motor for a chainsaw boat is fixed to the rear side of the swimming vehicle so that the screw is submerged 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 on the water surface, which is especially important for fishermen or hunters. The motor provides a good course for a small boat and at the same time is economical.
Useful advice! Not all models of saws 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 down.
Design features of snowmobiles and snow sleds
A chainsaw snowmobile is considered one of the most difficult homemade devices, because its manufacture will require a large number of additional parts, including:
- tracks and front skis;
- control consisting of a handle and a clutch.

Device, principle of operation and characteristics. Features of manual and electrified tools. Review of the best models.
There is another difficulty. In order for the snowmobile to move, it needs to be equipped with a suspension and transmission, so it will not be easy for a beginner to cope with such work.
The creation of a snowmobile from a chainsaw with their own hands begins with a supporting frame, which is a steel profile measuring 20×20 or 20×30 cm. A rocking lever is responsible for the shock absorption of the rear suspension, and a motorcycle–type steering fork is responsible for the front suspension.
It’s interesting! 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 trapeze. Despite the fact that this method is technically more complicated, it provides more convenient management.
Additionally, a snowcat with a motor with its own hands is complemented by a centrifugal clutch with a wedge-shaped belt and chain. To strengthen the traction force, a gear is attached to the caterpillar shaft, the diameter of which exceeds the drive part of the chainsaw shaft. For the normal operation of a homemade device, it is required to take a motor with a power of at least ten horsepower.
A simpler option is an aerial vehicle, 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, cross-country ability and stability. The main advantages are simple design and ease of manufacture. The rotating screw mounted behind the driver’s back must be closed with a protective casing made of fine mesh. The control is carried out by turning the skis, the gas lever and the brake. The optimal motor power is considered to be 5-6 horsepower.
How to make a moped out of a chainsaw or a bicycle with a motor
A homemade moped made from a chainsaw is unlikely to compare with an industrial version of the device, but as a kind of adult toy it will do quite well. By and large, the device is not a moped, but a bicycle with a chainsaw engine. This is due to the fact that the old frame from this vehicle is most often used.
It’s interesting! More advanced craftsmen do not take a ready-made frame from an old bicycle, but independently produce a welded structure made of metal pipes or a square profile for this purpose. But the main components, including bearings, prefer to use factory ones.
Before you put the engine from the chainsaw on the bike, you should take care of the availability of parts, such as:
- engine with gas tank;
- gearbox with a gear ratio of 18:1;
- shock absorbers;
Any motor on a bicycle from a chainsaw must be supplemented with a gearbox so that it is possible to adjust the rotation of the wheels. Sometimes gear pairs connected by a chain from a bicycle are used instead of a gearbox. If we take the mountain version of the bike as a basis, then a gearbox with a gear ratio of 1:15 or 1:20, supplemented with a variator, is more suitable here. The main advantage of a mountain bike with a chainsaw motor is that, unlike a conventional device, it will be able to accelerate up to 30 km/h.
Another simple-to-perform vehicle is considered to be a chainsaw cart, resembling a simplified car model, which is used mainly for circuit racing. The device is devoid of a solid body, there are no shock absorbers in it. The minimum number of parts makes it possible to facilitate the design and provide him with a greater speed of movement.
The frame is most often brewed independently from a metal profile, and old trolleys are used as a wheel donor. A bicycle chain is used as a drive on the rear axle, and you will also need a steering trapeze. To assemble the case, you will need to use a welding machine. Some consider the kart made with their own hands to be a children’s car with a gasoline engine, but it must be borne in mind that the vehicle is capable of developing decent speed.
What other homemade chainsaws can be made
The motor from a chainsaw can be used for independent movement of almost any vehicle. So, you can equip a child 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 the manufacture, you do not have to disassemble the chainsaw into parts. You will need to remove only the tire and the saw chain, which is replaced by a bicycle chain and serves as a part that transmits torque to the rear wheel.
In addition to the manufacture of vehicles, using some saw parts, it is possible to create a small mobile power plant that reaches a capacity of 5 kW. To create a generator, a chainsaw will require a motor, a steel frame, an electrical distribution box with connected sockets, as well as a gearbox with which the torque will flow to the generator shaft.
Some homemade chainsaw chains are popular among the forged ones, for example, some create one-piece knives. To do this, the chain is divided into pieces, from which the bases of the blades are then welded by incandescent them to 850 ° C. The molten chain is pressed until the voids between the links disappear.
To create homemade chainsaws, you need to know the basics of simple mechanics, because you need to properly 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 buying, it must be taken into account that the saw must be easy to understand, and the parts for it must be available for sale. For the manufacture of devices, it is better to take ready-made drawings, especially if you have not previously had experience in creating homemade devices.
