Homemade chainsaws have been the main topic for domestic craftsmen for many years. The devices they created help make many household jobs easier. 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 allows you to receive an electric current of 220 V at the output. The power of such a gas generator is enough for lighting, power electrical appliances and tools, household appliances.
Order of operations:
- A bracket is made and the electric motor is attached to it. Install the resulting structure on outer end chainsaw tires. 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.
- 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 total capacity 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:
- A rigid frame is made from pipes. Welding is used.
- 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.
- 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.
- 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.
- 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.
In addition to the grinder, the chainsaw is also a favorite tool for craftsmen for making homemade items. Different high power and complete autonomy in operation (no electricity required), the chainsaw is great for making vehicles, machine tools, and other equipment.
This article from a construction magazine talks about what can be made from a chainsaw, no matter which one, Ural, Druzhba or Taiga. These homemade ideas were collected on the Internet; they are incredibly popular among craftsmen.
Chainsaw - very handy tool for making homemade products. By adapting it to a special platform with wheels and connecting the chain to the shaft on which the blades will be installed, you can get a powerful lawn mower. By the way, in order not to bother for a long time, you can install a sprocket from the rear wheel of a bicycle on the shaft. 
In addition, a chainsaw can be used to make an excellent sawmill, since remodeling of this instrument, in this case, is also minimized. 
In general, all homemade chainsaws can be divided into two large groups:
- The first group includes those homemade products, in the manufacture of which there is practically no need to disassemble and modernize the chainsaw;
- The second group of homemade products includes all kinds of equipment: snow removal machines, mopeds, snowmobiles, ATVs, etc. In other words, complex mechanical devices, for the manufacture of which you will have to radically disassemble the chainsaw, make a water or air system cooling, in general, completely change this gasoline tool.
Let's look at what can be made from a chainsaw, which will definitely come in handy in the household. 
So, for example, based on the Druzhba chainsaw you can make the following homemade products:
- Powerful boat engine;
- Gasoline grinder;
- Sawmill;
- Motor cultivator;
- Lawnmower.
If it concerns car homemade products, then from almost any chainsaw you can make: 
- Moped, if you install a chainsaw on a bicycle;
- Snowmobile and snowmobile;
- Snow blower;
- Quad bike;
- Scooter.
Of course, the second group of homemade chainsaws requires a thorough approach and a complete study of the design. 
Also, you will need to purchase everything necessary materials, and in some cases, you can’t do without a welding machine.
The easiest to make is a homemade sawmill from a Ural, Taiga or Druzhba chainsaw. The essence of the work homemade sawmill lies in the fact that there is one large guide along which the chainsaw moves back and forth on a movable sled. 
As a guide, you can use a rail or several long but even ones. metal corners. The platform on which the chainsaw will subsequently be attached is made of a piece of thick steel, the thickness of which must be at least 5 mm.
Deserves special attention moving part sawmill, the one through which the platform moves along the guide. As rollers, here you can use metal pipe with rubberized surface. It is very important that the width of the moving part matches the width of the guide. 
As you can see in the photo, a log located next to the sawmill is quite easily cut into several parts using a chainsaw moving along a guide. Thus, you can save a lot on the purchase of a sawmill, and, as you can see, the chainsaw practically does not need to be altered, disassembled, etc. in any way.
As mentioned above, you can use a chainsaw to make various homemade products for your home and garden. Some of these homemade products are a mower and a walk-behind tractor. With a mower made from a chainsaw, things are not as difficult as with a walk-behind tractor, for the manufacture of which you will have to weld a metal frame, and then fit two wheels on the side to it. 
The principle of making a walk-behind tractor from a chainsaw is to use several sprockets that could transmit rotating force to the knives. For these purposes, the sprockets are located on the sides of a metal shaft on which several knives are welded. 
A homemade walk-behind tractor from a Ural or Druzhba chainsaw will become a real helper for those who have a fairly large garden. Perhaps such a walk-behind tractor will not be very powerful, but it will be quite enough to solve the main task of cultivating the land.

- This is a device that is sometimes simply irreplaceable in the household. Speed, high productivity, ease of operation are just a few of the advantages of this device.
However, not all consumers know that the use of a chainsaw is not limited solely to working with wood, and many of its structural parts are so functional that it becomes possible to build completely new mechanisms that are completely different from the original design of the gasoline machine.
This is due, first of all, to the design characteristics of the chainsaw: its engine is reliable and unpretentious, and fuel leakage is almost completely eliminated. We will talk further about what can be made from a chainsaw.
Features of creating a motor drill from a gasoline saw
In order to make a motor drill with your own hands from a chainsaw, you first need to adjust the engine rotation speed, since maximum performance for comfortable and safe work not required.
An element such as a gearbox, which needs to be attached to the chainsaw engine, can cope with this task. At this stage, it is important to consider the fastening system so that the parts future design were tightly connected to each other.
In order for the device to work reliably, the drill and knives for it must be selected so that these parts coincide in rotation with the “native” mechanism.

Making a scooter from a chainsaw
With the help of a chainsaw engine, you can assemble not only accessories for manual use, but also complete vehicle, operating on combustible fuel. One of these designs is a homemade scooter with a chainsaw motor.
To create this device, you will need a regular scooter equipped with a hand brake system and inflatable wheels. The engine from the saw must be mounted on the rear platform of the scooter and make sure that the line of the motor stars and the rear wheel coincides.
To control the level of energy supply to such a scooter, the manual accelerator must be connected to the wires responsible for turning the chainsaw motor on and off. If difficulties arise, it is possible to install a special pedal.

How to install a sawmill using a chainsaw?
One of the devices where the structural parts of a chainsaw are used to work with wood not only for the purpose of sawing it is a sawmill, with which you can qualitatively cut beams of the required diameter.
Of course, initially the well-known Druzhba saw was designed as a unit intended for cutting firewood, felling trees and similar work. Gradually, they began to produce attachments for it, which significantly increased its functionality. Accordingly, the popularity of the Druzhba chainsaw among the population began to grow. Craftsmen appeared who created some improvements and additions for it on their own. Let's say right away that the resulting devices were quite original.
Technical capabilities of "Friendship"
Currently in almost any store garden equipment there is very wide choose chainsaws from many manufacturers. And there are even more such devices in online stores! In this regard, old Soviet chainsaws are now undeservedly forgotten and are used quite rarely.
However, new devices with certain breakdowns simply cannot be used anymore. The same cannot be said about the good old “Friendship”. Many people know that after it becomes impossible to work with it for its main purpose, this chainsaw gets a second, no less vibrant life.
Today, homemade products from the Druzhba chainsaw are most often found in villages where real craftsmen still live. And savvy people, having this wonderful product of the domestic industry in their hands, were able to make quite decent functional devices from it.
It turns out that, after working for a sufficient period of time felling trees, this chainsaw for some reason is not thrown away. It's all about the universal drive, which allows you to use such saws in other devices in the future. So, it became possible to use the Druzhba chainsaw as a basis for some other units due to:
Quite a powerful engine;
The ability of the device to withstand extreme conditions;
High autonomy of the saw;
Sufficiently compact and light weight.
The working parts of the chainsaw rarely fail, largely thanks to the clutch, which eliminates overload. This part is sealed and is less susceptible to blockages that cause breakdowns.
What devices are made based on the Druzhba saw?
If we take into account the above-described advantages of a chainsaw, it becomes clear how such a unit can be used in the future in almost any area of human activity. For this reason, many will probably be interested in what can be made from a Druzhba chainsaw and how to then use it in their personal household. Here is a list of fairly simple devices:
Bulgarian;
Boat engine;
Walk-behind tractor;
Motor cultivator;
Moped from "Friendship"
To more complex devices which we managed to implement on the basis of the Druzhba chainsaw, it is worth mentioning:
Helicopter;
Snowmobile;
Snow blower;
Snowmobiles;
How to make the Druzhba saw serve in another form?
If you are eager to give a second life to such a saw, then you will need some design skills and knowledge. After all, you will have to work with a gasoline unit, and sometimes you will have to independently grind out parts for a new device on lathe. Although a familiar turner may be hired for these purposes. Or the part can be made on a CNC machine.
It is also important to understand that remodeling a saw will sometimes not produce the expected power. For example, a motorized cultivator that “got” an engine from Druzhba is unlikely to be able to easily cope with a fairly large vegetable garden. But gradually with its help it will be possible to process small area. Many craftsmen will probably be able to build such a motor cultivator in which the engine energy will be transferred by a gear to the drive wheel.
Chainsaw mower
Often in the village you can also see a working mower, for which the Druzhba chainsaw was also converted. This unit is operated non-stop during haymaking. long time and it works for more than one season. To create such a mower, the tire is removed from the saw structure along with the drive sprocket and chain. In this case, the saw is quickly converted to its original state and can easily cut wood in winter.
If you have, as they say, even hands and a small garden plot, then it is not necessary to purchase a walk-behind tractor. After all, servicing, and even more so purchasing, is quite expensive. However, if you have an old Druzhba saw or the opportunity to buy it for a small amount, it is quite possible to make a walk-behind tractor with your own hands. The very principle of this modification is to use two sprockets as a force transmission system. Like homemade walk-behind tractor It can easily be used when working on a small garden plot.
Walk-behind tractor
Everyone knows the Russian deputy, who often presents real “surprises” in the form of heavy snowfalls. If you have serious complications with snow removal during such a period, then you should think about designing a small snow removal device, the basis for which can be an old Druzhba chainsaw. For such a snow blower, you will need to design a screw mechanism. In order for it to efficiently perform the duties assigned to it, the material for its manufacture must be elastic and durable. Rubber has these characteristics. A sled can be used as a basis for moving a homemade snowplow. It is possible to dump snow during refurbishment water pipe with a certain bend.
Sometimes a farm requires a device such as a sawmill. Of course, it is unlikely that anyone will install such a large device on their site. In the same time mobile device, capable of quickly sawing a tree trunk to specific sizes, may be quite in demand. Therefore, the chainsaw sawmill “Druzhba” was also implemented by folk craftsmen. There are several types of such devices. They can differ mainly structurally.
For a sawmill from the Druzhba saw, some kind of stationary frame must be created, which allows you to fix the saw itself in a certain position and set the dimensions for the cut. But there are also designs that take up very little space and can even be taken with you into the forest right away. And already in place, dissolve the wood.
Chainsaw pump
Sometimes at the dacha or suburban area There is a situation with a lack of water. The reasons may be different, but a chainsaw can also solve this problem. To do this, you need an appropriate nozzle that will be able to pump water. Of course, using a saw for regular water supply is irrational. However, it is quite possible to establish an emergency water supply.
Pump attachment for chainsaw Druzhba
Such a device could be used, for example, to pump water from a cellar during the spring melting of snow. Sometimes it is used for watering the garden and other needs. Structurally, such a nozzle is centrifugal pump, which has a bracket with holes that allow you to attach the entire device to the chainsaw. The turbine of such a pump is driven into rotation through a special pulley.
"Friendship" and fishing
Our fishermen often have remarkable imagination. Therefore, their attention did not pass over the “Friendship” chainsaw. On its basis, for example, motors for boats, ice augers, etc. are made.
In order for this saw to serve as a boat motor, a special attachment is required. This is a three-bladed propeller design that includes a gearbox. Typically its gear ratio is 2 to 1, which allows the fisherman’s boat to move along the water surface at a speed of about 20 km/h. In this case, fuel consumption is recorded at about 1 l/hour.
For winter fishing, some fishermen throw in the towel and buy a drill bit. Buying a motorized drill together is not always rational due to some difficulties with the possibility of its collective use. It turns out to be expensive for one person to buy such a device, but the drill attachment is a good alternative. Such a device must have a gearbox in the form of a worm or V-belt drive, which will reduce the number of revolutions of the saw engine for normal operation nozzles
When going fishing or hunting, it can be useful to equip your vehicle with a special winch, for which the Druzhba saw can also be the power unit. If the unit itself is not very powerful, then it will be possible to purchase a diversion block, which will increase the power and change the trajectory of the pulled vehicle.
The chainsaw is very popular among home craftsmen because it is a universal drive for original homemade designs.
Light weight and solid power combined with compact dimensions allow this “lumberjack’s dream” to be combined with an ice auger and a bicycle, a sawmill and a winch.
Interesting homemade products from a chainsaw can be made by anyone who confidently works with welding machine, a grinder, and, if necessary, can stand on a lathe.
In this case, knowledge of the basics of design and drawing will be very useful, since accuracy of all dimensions and quality of assembly are the main conditions for the normal functioning of a unit driven by a chainsaw.
Without going into technical details, consider the options most interesting designs with its use.
Homemade options
The first thing that comes to mind when you think about what can be done with a chainsaw is its use as a sawmill. Many developers had to split logs onto beams with this tool.
Holding the saw suspended in your hands, it is very difficult to control the accuracy of the entire length of the cut. Therefore, with a log length of three or four meters, it moves far away from the intended line. This problem can be solved quite simply. To do this, the chainsaw is rigidly fixed to a frame, which moves along a guide profile.
In this case, the log lies motionless and is neatly sawn along its entire length without wobbling or oblique seams. If you equip such a mobile carriage with four lifting screws, you can accurately set the thickness of the sawn timber.
A sawmill using a chainsaw will also work on boards without problems, only in this case there will be too much waste, since its cutting chain is several times thicker than the saw of a band sawmill.
Snowmobile
Easy homemade snowmobile The design of a chainsaw is more complex than that of a sawmill, since here you need to place the gas and clutch on the steering wheel, and also take care of the shock-absorbing suspension of the supporting frame.
In addition, you need to develop it yourself or use ready-made drawings of the caterpillar and correctly transfer torque of sufficient power to it from the motor. Since the chainsaw does not have its own transmission, the clutch on such a snowmobile is fitted with a centrifugal clutch with a serpentine belt and chain.
To increase traction, a “traction” gear is placed on the caterpillar drive shaft, the diameter of which larger size chainsaw drive sprocket.
There are usually no problems with the steering mechanism, since it is taken from regular bicycle or scooter and modify it so that central axis moved the rods that turn the skis. The snowmobile engine power must be at least 5 Horse power, so it is better to use a Ural chainsaw for this purpose.
The winter line of homemade vehicles will be complemented by snowmobiles made from a chainsaw, which are structurally simpler than a snowmobile. Driving force screw tells them large diameter, which directly rotates the gasoline engine.
A significant limitation for the cross-country ability of such a vehicle is low power chainsaws. Therefore, you can only move on them along flat surface rolled snow, ice of a frozen lake or river. To travel across the fields you will need an engine with a capacity of at least 12 horsepower.
Those home inventors who would like to make a backpack-type helicopter from a chainsaw should know the same thing. Such a machine will require not one, but at least two engines operating in a coordinated mode.
Moped
This vehicle is most often made for the sake of principle, and not for practical use. The main driving force of its creator is the desire to test his strength as a mechanic and prove to others the original use of this cutting tool.
The basis for the design is usually my grandfather’s old Druzhba chainsaw and an equally ancient bicycle, with which you can conduct any experiments on converting the frame for mounting the drive.
Power is transmitted here through a gear pair using a bicycle chain, and the start of such a homemade product is reminiscent of preparing for cutting firewood.
Less common are more advanced models, the basis for which is a mountain bike equipped with reliable brakes and shock absorbers. This chainsaw moped is equipped with a gearbox with a gear ratio of 18:1 and a CVT transmission, which allows you to comfortably move on it at the speed of a regular bicycle.
boat motor
This option for using a chainsaw is quite simple, since the task here is to transfer torque from the saw motor to the propeller. A homemade outboard motor does not need to install a transmission. For it you will need to make a reliable adapter on a lathe from the saw drive gear to the propeller shaft. The propeller can be used from a standard outboard motor.
The photo shows an option in which the front propeller There is a gearbox that changes the angle of rotation of the shaft by 90 degrees. In more simple models they do without it by mounting the engine on the boat so that the shaft is immersed in the water at a slight angle.
Motor cultivator
It is difficult to make a full-fledged walk-behind tractor from a chainsaw due to lack of power and traction. But many home craftsmen were able to build a lightweight motorized cultivator based on it.
The design of such a machine is very simple: the motor rotates a pair of gears and transmits increased traction force to one drive wheel.
snow blower
The chainsaw motor doesn’t care whether it rotates the cutting chain or the auger mechanism of a snow blower. Here everything depends only on the design abilities of the creator and his ingenuity.
Using a Stihl chainsaw with a power of about 3 kW, you can easily build a good device for clearing an area of loose snow. To simplify the design, some craftsmen refuse to install wheels and use conventional sled runners.
The most important part, which determines how well a homemade snow blower will do its job, is the auger assembly. It is driven by a gear pair and a chain. The blades are made of thick cord rubber, and the intake device is made of galvanized steel sheet.
Frame design
You can fit a plastic snow thrower under the snow thrower. sewer pipe, securing it to the intake body.
The chainsaw asks for the sky
The most daring inventors have long been eyeing the possibility of using a chainsaw as an engine for aircraft. However, this instrument is not strong enough to master airspace. Therefore, no one has yet succeeded in making a backpack helicopter out of one chainsaw.
Calculations have shown that this requires at least four chainsaws (total power from 20 hp) of a forced design, which would allow them to increase speed several times and work in a coordinated mode.
Motor drill
This device is useful not only when building a fence or foundation from screw piles, but also during winter fishing, when you have to drill dozens of holes in thick ice.
Since the ice auger operates at low speeds, to adapt the chainsaw motor, it is connected to the auger through a reduction worm gear.
Winch
Motor winch - very useful device, because with its help you can not only easily pull out a stuck car, but also lift a heavy load to a height, pull a boat onto land or move a cut tree.
The power of such a homemade product depends on the power of the chainsaw used, and its pulling force can reach 1500 kg. Such a winch must be equipped with a sling belt, hooks and anchors for attachment to the ground, tree trunk or car.
Power station
The camping power station is assembled on the basis of Ural or Druzhba chainsaws. It consists of a frame, an engine with a gear reducer, a control panel, a generator and connecting electrical cables.
1 – chainsaw 2 – gearbox 3 – cord drive belt 4 – tension bar 5 – generator; 6 — control panel; 7 — clamps; 8 - supporting frame; 9 - saw tooth stop; 10 — nut for fastening the frame to the gearbox; 11 - drive pulley
A good owner will not throw anything away in vain, especially if we're talking about about quality metal. If you understand the nuances heat treatment metal, you can do it solid forged chain knife, which has served its resource.
This thing looks no worse than the creations of Arab blacksmiths who forged swords from the legendary damask steel.
