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.

The chainsaw is an indispensable tool due to its versatility

What kind of homemade products can be made from the Druzhba chainsaw 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 for the classic design, you will be able to expand the possibilities of using the device on the farm and get the following devices:

You can purchase special attachments for a chainsaw or make the necessary tool using it.

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

Some craftsmen, armed with basic knowledge of mechanics, create additional accessories for chainsaws with their own hands, which can significantly expand the scope of use of the tool. 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 hole;
• 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.

As a rule, homemade products are made from chainsaws “Ural”, “Druzhba”, “Shtil”

This is interesting! Homemade Ural chainsaws 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 parts from overload due to overheating or other breakdowns. Also, the tightness of the motor makes it possible to use the device in any position.

How to choose a tool?

There are numerous types of additional saw attachments available on the market. These include a gas cutter, a sawmill, a pump, a drill, etc. Despite such a wide range of attachments sold, you can also make your own additional mechanism for a chainsaw.

The availability of available materials allows anyone who understands the technical structure of tools to make a special device out of a chainsaw that will be useful on the farm.

To choose a saw that will serve as the basis for a new accessory, you need to consider the following qualities:

• Saw power. A motor operating within 2-3 kW will be sufficient for many applications.
• When choosing a chainsaw, it is best to focus on inexpensive models, since the engine may not be able to withstand the new load. When buying an expensive model, you can lose a lot of money. It is recommended to use outdated types of saws so that in the event of a breakdown you do not regret wasted investments.
• Easy to disassemble the saw so that you can easily assemble and disassemble the device, as well as choose cheap spare parts.

For the application of modifications, such chainsaw models as Ural, Shtil or Druzhba are suitable.

The additional attachments made can be divided into the following categories:

1. Simple mechanisms (grinder, pump, winch, drill, walk-behind tractor, boat motor).
2. Complex mechanisms (sawmill, snow removal device, power plant, snowmobile).

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.

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

The corroder 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:

1. Drums. The main area of ​​application is bark removal, the second name is decanter.
2. 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.

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.

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.

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.

How to properly break in a saw

When mastering the skills of how to use a chainsaw, you should pay attention to the break-in procedure. The manufacturing level of modern chainsaws is quite high; they do not require special running-in. The only condition is the need to withstand the cyclic operating mode at a gentle pace for the first time: sawing for 1-1.5 minutes/idling for 10-15 seconds. After using 8-10 full fills of the fuel tank, the engine reaches full power.

Running in the engine exclusively at idle speed, as was previously practiced with other models of chainsaws, leads to the formation of carbon deposits due to incompletely burned oil, which subsequently provokes serious damage to the cylinder-piston group.

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 of a 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. 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 store-bought one.

Helpful advice! 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.

Running in a chainsaw

Why do you need to break in a chainsaw?

Before starting the chainsaw, it is necessary to run it in, during which the parts of the CPG will rub together. Optimal clearances will be formed in the tool engine and in the piston system, affecting the efficiency of the gasoline saw. After this, you can begin the main work.

After grinding in the parts, the piston will be able to optimally transfer heat to the cylinder, which protects it from excessive heating. If you do not run-in, you can significantly reduce the performance of the chainsaw. If you start working with the tool too quickly, a number of malfunctions may occur, including hanging piston rings, scuffing in the cylinder, and engine jamming.

How to break in a chainsaw: Instructions

First you need to warm up the engine by starting it and letting it idle for up to 5 minutes. After this you need to start sawing the wood. It is best to take small pieces or logs for this (up to 15 cm in diameter). During break-in, you need to use a cyclic method - alternate the following steps:

• 10-15 minutes of work;
• Rest for 5 minutes with the engine off.

For the run-in to be considered complete, you need to exhaust 2-3 volumes of the fuel tank. After this, the engine will begin to produce the required operating parameters. During break-in, you should never overheat the engine, idle for too long, or overload the saw.

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 DIY snow blower 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.

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.

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.

Homemade chainsaws: boat motor and other vehicles

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

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.

Replacing the chainsaw bar and its fastening elements

To replace fastening elements, tires and chain fittings, it is necessary to disassemble the entire fastening mechanism. It doesn’t hurt to prepare in advance a rectangular piece of fabric or cardboard, as well as free space on the table for disassembling the tool and temporarily placing the removed parts.

Chainsaw bar mounting diagram

Replacing fastening elements and the chainsaw tire is necessary when:

1. Critical wear of the landing groove or shank elements.
2. Damage to the casing.
3. Failure to secure the fastening bolts.
4. Damage or deformation of the tire body.
5. Abrasion or breakage of the teeth of the drive and driven sprocket.
6. Damage to the grooves for supplying lubricant to the chain.
7. Worn chain tensioner.
8. Worn seat groove and tire retainer.

That is why the saw bar and fastening elements are consumable parts - to replace them you only need one universal wrench, supplied with the tool. And, of course, knowledge of the algorithm for disassembling, assembling and adjusting the mechanism.

Chainsaw with tire removed

To disassemble the tire mount:

• place the engine vertically and, having unscrewed the corresponding nuts, remove the drive sprocket cover;
• lift the bar by the front end and turn the chain clamping screw, releasing it from the bar groove;
• pull the chain from below and, turning the clamping screw, release it from the groove;
• remove the chain from the drive sprocket and pull it out from under the casing, then put it aside;
• if there is damage or signs of wear, the casing and mounting gaskets should be replaced;
• Remove the chain bar to be repaired or replaced from the groove mounting.

After this, the chain must be put on a new bar and the latter must be installed in the groove to be installed. Next, the headset is engaged with the drive sprocket and closed with a lid. Immediately before starting work, do not forget to check the chain for slack and the quality of its tension.

The chainsaw is back in action

If the new bar is attached and the headset is installed correctly, the chainsaw is ready for use again. By the way, just in case, you should make sure of this by sawing several thin branches.

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

This is 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 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.

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

This is interesting! 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.
