How to make a homemade snowmobile from a chainsaw and a walk-behind tractor

With the beginning of winter, especially snowy ones, problems associated with movement appear.
Few people know that a snowmobile can be constructed from available materials as an alternative means of transportation in winter conditions. At the same time, there is no need for serious expenses. Moreover, if there is a lot of snow, you won’t be able to get far by car, but a snowmobile will allow you to move in such conditions without any problems.

The simplest homemade chainsaws

Below are different options for devices made from chainsaws.
Anyone can use such ideas in their own household. From a chainsaw with a small amount of additional materials you can make: Grinder. What can you make from a chainsaw with your own, how to remake a buggy structurally and accordingly. The main system of such a device is a bearing assembly with a shaft. So, many people managed to make a simple chainsaw out of an old one. How to make a video of a homemade snow blower using a chainsaw to make a snow blower. A driven pulley is installed at one end of it, which rotates using a V-belt. A mandrel for cutting wheels is attached to the other. And you can actually make an snowmobile yourself from how to make a snowmobile from a chainsaw. Depending on their brand, such a grinder can cut stone, metal, brick and other building materials.

Calculation and assembly of caterpillars

Do-it-yourself homemade snowmobile from a walk-behind tractor: homemade video
The caterpillar is a tape, on the outer surface of which the tracks are attached. Tracks are rigid lugs installed along the entire length of the tracks. Track options:

• Made from 3mm thick transport tape.
• From a car tire.
• From V-belts.
• Ready-made factory-made tracks.

The conveyor belt must be looped. Its strength is only sufficient for light snowmobiles with engines no more powerful than 10 liters. With. Car tires are stronger than tape and are suitable for powerful engines. Solid tires do not need to be looped, so the likelihood of a rupture is minimal. It is more difficult to choose a tire of the required length than a tape.

Finished tracks are removed from other similar equipment (snowmobiles “Buran”, “Sherkhan”). They are equipped with lugs from the factory. The products are not suitable for use with low-power motors from walk-behind tractors. Homemade snowmobiles made from Buranovsky tracks must have gears from the same “donor”.

The size of the caterpillar is selected according to the required driving characteristics: the larger the width, the lower the handling, but the higher the maneuverability. The minimum area of ​​the contact patch from the snowmobile (skis and tracks) must be such that the pressure from the equipped vehicle does not exceed 0.4 kg/cm2 of surface. Light snowmobiles use a 300 mm wide conveyor belt, cut lengthwise into 2 strips of 150 mm each.

Preparing the Tape

The tracks are attached to homemade tracks with M6 bolts with a wide head. The bolts are fixed with a nut, a washer and a groover are used. Before fastening, leading holes with a diameter of 6 mm are drilled in the tape and tracks. When drilling, use a jig and wood drills with special sharpening.

The conveyor belt is also looped with M6 bolts. To do this, the edges of the tapes are overlapped with an overlap of 3-5 cm, the connection contains 1-2 rows of bolts. For a 150 mm wide track, the following distances are maintained:

• From the edge of the tape 15-20 mm.
• Between bolts on tracks 100-120 mm.
• Between the bolts when banding 25-30 mm.

Homemade lugs

The tracks are made of polyethylene pipe with a diameter of 40 mm with a wall thickness of 5 mm, sawn in half in the longitudinal direction. The entire section of the lug is adjacent to the tape. In light snowmobiles, one track connects the tracked pair. With a track width of 150 mm, the track length is 450-500 mm.

The lugs are cut using a wood circular saw. They use a special machine with two guides (metal and wood), rigidly fixed on a fixed tabletop. The walls of the pipes are sawed one by one.

The distance between the tracks depends on the parameters of the gears on the drive shaft. Typically 5−7 cm. The specified distance is maintained with an error of no more than 3 mm. Otherwise, the operation of the drive is disrupted: the lugs “run” onto the teeth of the drive wheels, the caterpillar begins to slip and fly off the rollers.

On caterpillar tracks

Track supports are used more often than others, simultaneously performing the function of propulsion. The reason is high efficiency and reliability. This design allows you to reach high speeds while maintaining stability and maneuverability. There are several options for how to make tracks for a snowmobile with your own hands:

• from a conveyor belt,
• from truck tires,
• from driving V-belts.

Plastic or PVC tubes no larger than an inch in diameter, sawn along the axis, must be bolted across the conveyor belt.

Even a child can handle such a lightweight device.

Old truck tires with winter tread can also be used as tracks if you cut off the sidewalls. They don’t need crossbars, but you will have to sweep the edges with fishing line in centimeter increments, otherwise the tire will quickly become frayed.

Drive belts, just like the conveyor belt, must be equipped with lugs. Several parallel belts, 2 or more, are connected to each other by transverse strong lugs, attaching them to the belts with rivets or with screws. The distance between adjacent hooks should be equal to the pitch of the drive sprocket.

Tracks made from conveyor belts or belts are often reinforced with a chain, which increases the reliability and durability of the propulsion unit.

These snowmobiles combine lightness with a reliable drive.

One of the varieties of tracked snowmobiles is a motorized dog, which was named after its resemblance to a sled dog. At the expense of maneuverability, the design was lightened, and the traction force also increased. But this is the most effective towing mechanism in the snow.

To change direction, you need to make significant efforts to shift the center of gravity of the motorized dog.

The basic dimensions for assembling a two-seater snowmobile, indicated in the drawing, will help make the ride comfortable. Other sizes will depend on the availability of spare parts and assembly diagram.

When driving, discomfort from headwinds is alleviated by installing motorcycle glass and mudguards for the feet. But it is impossible to completely protect yourself from the cold wind on such transport. For comfort, you need a completely enclosed cabin, which means the weight will increase and a more powerful engine will be required.

A snowmobile with a car engine is designed for long trips over long distances. With heat-insulating body material, the ride is comparable to the comfort of a passenger car.

And the easiest way to achieve comfort is to simply place a rear-wheel drive vehicle on wide supports such as skis, tracks or pneumatic wheel tubes, and also drive the standard wheels to the snowmobile propulsors and attach the front ski to the steering bipod.

During manufacturing, it would be useful to provide a replaceable scheme for replacing wheels with skis and back, if you use spare parts for the conversion.

Which chainsaw should you choose?

How to make a homemade plow for a mini tractor

To create a snowmobile, you can use various chainsaws. The most suitable options would be the Druzhba, Ural and Shtil models. And which unit to choose - it all depends on your desire.

Friendship

The main positive side of using the Druzhba chainsaw as a starting material for making a snowmobile with your own hands is its simplicity of design. Here is an elementary assembly, where each part plays its role. No extras, just the essentials.

The negative aspects of this unit include its heavy weight. Moreover, the use of safety covers is not provided here. And in general, the chainsaw is already obsolete.

Technical certificate:

• power – 1 kW;
• weight - up to 12 kg;
• engine (two-stroke);
• tire length – 45 cm;
• fuel (gasoline).

Ural

The specialized professional chainsaw "Ural" was created specifically for felling tree trunks. This is a very convenient mechanism in operation, characterized by great power. This unit is an environmentally friendly device that can be used even in harsh winter conditions.

If you decide to use a Ural chainsaw to create your own snowmobile, this is the right choice. Since the technical parameters of this machine fully meet the stated requirements.

Technical certificate:

• engine (gasoline, two-stroke, single-cylinder);
• power – 3.68 kW;
• weight – 11.7 kg;
• parameters – 46 x 88 x 46 cm.

Calm

The Shtil chainsaw is also suitable as the main mechanism for creating a snowmobile. It is made of environmentally friendly material, harmless to humans, has good power and operates silently. Therefore, your trip will be very comfortable.

How good should it be?

The most important element in this device is the engine. All other details, such as a chain or tire, do not play a significant role in the design of such a vehicle, so the main thing is to monitor and control the operation of the motor. If it is in good working order, the snowmobile will always be on the move. If you decide to take the engine from imported chainsaws, you don’t have to purchase a new device under warranty in the store. A used option is also quite suitable.

The only part in a chainsaw that must also be in working order along with the engine is the gearbox. It will also be useful to us in our work.

Why do you need a drawing?

How to make a homemade earth drill (pit drill, earth drill)

Assembling a snowmobile begins with a plan, that is, with a drawing. It is recommended to do it yourself, taking into account the non-standard and unique nature of the planned man-made mobile vehicle. Here it is necessary to remember that this working diagram is needed for internal use, therefore the level of drawing art does not matter, but the main thing is how clearly the plan will be embodied in the diagram

When drawing up a drawing, it is important to take into account the weight of the structure: the lighter the snowmobile, the higher its maneuverability will be.

Frame

According to an individual drawing, the frame is welded in the form required for this version of a homemade snowmobile. Wooden bars or metal pipes are used as the starting material. The easiest way is to make a wooden frame. Its main advantages are that it is easy to repair in the field (there is a lot of wood around), and it holds the car well on ice. The metal frame is welded from pipes of a certain square section, the size of which depends on the load. Its advantage is that it is a stronger and more durable structure than a wooden one. As always, there is a ready-made option - take a frame from a moped.

Track assembly

After making the frame, they begin to create tracks, consisting of tracks and rigid hooks installed along their entire length. Caterpillars can be made from conveyor belts or car tires. You can use ready-made industrial tracks. An advantage of purchasing ready-made tracks may be their special regional purpose, where climate, terrain and travel conditions are taken into account.

Wheels are installed inside the homemade tracks. With their help, the tracks on which the lugs (or simply hooks) are located rotate.

A common option for their manufacture is plastic pipes. They are cut into pieces

The lugs are attached to the tracks with bolts, and it is important to maintain the same distance between the lugs so that they do not disturb the movement of the caterpillar

The wider the tracks, the more difficult it is to control the vehicle, but the higher the maneuverability becomes. The thickness of the tracks must correspond to the engine power.

Chassis

After the frame and tracks are ready, they begin to assemble the structure with the chassis.

• Using front suspensions, the steering and skis are attached to the frame.
• The steering wheel is often taken from a motorcycle or scooter, but in case of non-standard solutions, it is assembled independently, based on personal preferences and convenience.
• Skis are often used ready-made. Typically, a ski consists of the following parts: base, shock absorber, link leg, fork, its rod and bipod. But there are options for making your own: from plywood, plastic, metal.
• The rear suspension connects the engine to the tracks.
• A motorcycle chain can be used as a drive.
• The fuel tank is chosen based on safety, economy and practicality. The capacity of the container (made of plastic or metal) is determined by considerations of the necessary distances to be overcome.
• The seat is made to order according to individual preferences, since the control of the snowmobile will depend on convenience and comfort. The best choice is a seat made from quality materials.

Other creation options

There are other ways to build a snowmobile using skis or a crawler rear. These makeshift snowmobiles and snowbikes use bicycle wheels.

Snowmobile from scooter

One of the simplest homemade options you can create yourself from any scooter or moped. The only differences here are the frames, the sizes of the tracks, and other parts. Such a snowmobile is unlikely to be powerful and will have difficulty moving through snow-covered snowdrifts. Therefore, they use wheels of a smaller diameter and increase the frame. This homemade moped moves well on light snow or crust. In the spring, you can replace the ski or track back with wheels and get a scooter or moped again.

Chainsaw snowmobile

Using a motor from a trimmer, many craftsmen can independently make various devices: cultivators, motorbikes, snowblowers and, of course, snow scooters (or snowmobiles).

The product is not particularly powerful, but reliable, lightweight and easy to use.

Snowmobile from a motorized dog

It is even easier to get a snowmobile from a motorized towing vehicle or a motorized dog; there is practically no need to reassemble it - just add skis with steering and make minor changes.

Snowmobile from ATV

The ATV undergoes even less alteration for better maneuverability in winter snowy terrain. Essentially, everything is limited to tuning, which consists of installing tracks, although this process is expensive and time-consuming.

Snowmobile on tubes

About homemade products using cameras or pneumatics has already been noted above. The homemade device consists of a control support ski and a leading support pneumatic.

The advantages include the high cross-country ability of the vehicle, and the disadvantages include low maneuverability.

Transformable snowmobile

A folding snowmobile is called a mini snowmobile or transformer. Its main difference is convenience and ease of use. It easily fits when folded in the trunk or even on the seat of a car.

Snowmobile from a cultivator

And another savvy option for inventive use - a snowmobile made from a cultivator. Usually, every farm has a cultivator and sits idle in the winter. Using the engine according to the assembly diagram, we make an apparatus for winter movement. The power is small, but in reality it is practical and effective.

Step-by-step instruction

The manufacturing diagram and drawings greatly simplify the process of making a snowmobile yourself. But if you understand how the power plant, track, skis and transmission need to be connected, then you can operate without these applications. By the way, it’s quite possible to assemble a children’s mini-snowmobile in an intuitive way from a bicycle, snow scooter or sled. The schematic diagram for making a homemade snow scooter consists of 4 main stages.

At the first stage the front skis are created , after which the master decides how he will secure them. At the second stage , methods of transfer to the wheel are organized . to weld the support frame for the vehicle , and finally - at the fourth stage - install all the attachments.

Before starting work, you should definitely stock up on polished metal corners, spacers with ties, plywood and steel sheets, as well as clamps and bolt fasteners.

How to make a homemade snowmobile from a chainsaw?

The axis of the rollers can be borrowed from a potato digger. Their ends need to be released a little. This is done so that the axles can be sharpened and threads of 10 mm can be cut. When making a homemade snowmobile from a chainsaw, do not forget about the spacer bushings. They should be placed directly on the axes of the unit. It is best to take bushings made of duralumin pipe. Next, the axles are secured using fastening bolts or a locknut. Using the same principle, a homemade snowmobile is assembled from a Druzhba chainsaw.

At the next stage, it is necessary to weld 3 racks made of steel angle to the spar. The best option would be corners measuring 30×30 mm. They also need to be connected with steel crossbars. This way the structure will form a small portal. Make a platform between the front part and the middle on the right side - weld a 2 mm steel sheet. After this, place the chainsaw gearbox and the intermediate chain drive shaft here.

The front part of the frame must connect to the front axle crossmember. As a beam, you can use a regular water pipe with a diameter of at least 30 mm.

Those who made homemade mini-snowmobiles from a chainsaw take the tracks from the old Buran. However, for it to function normally, it needs to be shortened slightly (by 500 mm) and sewn together with transport tape. Make the gears from a 15 mm nylon sheet.

It will be tubular type with a diameter of 28 mm. A round flange with holes for the gears should be put on it. Press and weld solid pin tips into the ends of the drive shaft. The latter must be machined for bearings.

The dimensions of the tension shaft tips must be the same and fastened similarly to the drive devices.

Seat

The box under the seat is most often made with your own hands from boards? Suitable thickness 20 mm, plywood top. This is a box lid and a seat at the same time. It is attached on hinges, covered with foam rubber on top and covered with leatherette-type fabric. It is possible to use a ready-made seat from an old motorcycle.

Making a snowmobile from a chainsaw with your own hands is not so difficult if you have the technical skills, knowledge and necessary tools. And the more ready-made parts and spare parts from old equipment are available, the faster and easier it will be to create such a vehicle.

Snowmobile from a motorcycle: a guide for masters

Making a snowmobile from a motorcycle is not so easy. If the assembly of previous products did not cause any difficulties, then with this design you will have to suffer. The work will require not only tools, materials and equipment, but also skills in working with a welding machine and other equipment.

Snowmobile design technology

• A suitable frame is made from metal pipes of different diameters and steel corners. Its base is made in the form of a rectangle (its dimensions are 150 x 43.2 cm).
• The steering beam is constructed from metal corners (its dimensions are 50 x 50 x 5 mm), its parts are sheathed with dense metal overlays. The finished structure is installed in a horizontal position on a drilling machine.

Motorcycle Izh

• The frame and the finished beam are processed at the joints, special grooves are prepared for reliable fixation of the elements.
• The front crossbar of the frame is equipped with a strong corner.
• The seat is attached to the frame of the structure.
• Make holes in the side members.
• A channel is welded between the steering and middle sections.
• Select a suitable track sprocket and rubber band for further installation (suitable dimensions - 2200 x 300 mm, thickness - no more than 10 mm).
• The caterpillar itself is carefully sheathed with nylon so that the material does not delaminate during use.

Snowmobile from motorcycle

• A transmission is installed, which consists of a front and rear axle. The front one is the drive one, it consists of a tubular shaft, a track sprocket and rollers (the sprockets themselves are fixed with through bolts). The rear axle structure consists of a track drum and a tubular shaft.
• The skis are welded to the structure of the snowmobile (sheets of steel and metal corners are used for their manufacture).

The control system of a homemade snowmobile from a motorcycle is quite complex to design. It consists of:

• skis;
• longitudinal traction;
• lateral thrust.

Important! Experts do not recommend changing the motorcycle steering system; all controls must perform their original functions. From the information presented we can conclude: a homemade snowmobile from elements of a walk-behind tractor, chainsaw or motorcycle is a reality

Any craftsman can make it. For productive work you will only need certain skills, equipment, tools and materials

From the information presented we can conclude: a homemade snowmobile from elements of a walk-behind tractor, chainsaw or motorcycle is a reality. Any craftsman can make it. For productive work you will only need certain skills, equipment, tools and materials.

Walk-behind tractor base design

You can make a snowmobile from various equipment, for example, a moped, scooter, trimmer, etc. However, the best choice can be considered a walk-behind tractor. Since this unit remains unclaimed in winter, it can be safely taken as the basis for creating a snow scooter. The snowmobile attachment can be made on wheels and this design is simpler. The most difficult thing is to make a snowmobile with your own hands from a walk-behind tractor on tracks. However, it has higher cross-country ability, which can become the main criterion when choosing the type of structure.

It should be remembered that not every walk-behind tractor can be converted into a snowmobile. It is best to use units equipped with:

• Rear towing device.
• Medium-power air-cooled power plant.

The optimal choice can be considered Neva units. They are attractively priced and their engines are assembled in Japan. The design of a self-assembled motor sleigh can be divided into two main parts - the driving and driven ones.

The first category includes the motor from the walk-behind tractor, drive elements and the supporting frame. The driven part consists of:

• Steering column.
• Shock absorbers.
• The chassis, for example, is tracked.

Frame making

You should first study the drawings well. If you wish, you can make a mini snow scooter of your own design, but many people prefer ready-made solutions. To make the frame, you should use iron pipes. To give them the desired shape in accordance with the drawing, you will need a pipe bender. When this work is completed, it is necessary to connect all the frame elements by welding.

The next step is to fabricate the main subframe structure at the front. This is where the power plant and gearbox, for example from a Zhiguli, will be mounted. To solve this problem, a stand with holes for the motor is welded to the frame. The drive chain is installed in a special slot.

Chassis

One or two skis must be attached to the steering column using a swivel joint. It is better to use ready-made shock absorbers for the front suspension, for example, from a motorcycle. You should also decide whether tracks will be used for movement, or whether you plan to make a mini snowmobile on inner tubes. Each of these drive types has not only advantages, but also disadvantages.

The wheeled unit is more maneuverable, but is inferior to the tracked unit in cross-country ability. Tracks can be made independently from various materials, for example, a conveyor belt.

Snow scooter with motor

Argomak snow scooter with motor from a walk-behind tractor

DIY snow scooter with motor

Unfortunately, the production of motorized snow scooters is not currently established. This is probably due to the unprofitability of this type of “transport”. A snow scooter with a motor is a regular Energomash (“Argomak”) or “Snowball” snow scooter with an electric drive attached to it that sets the object in motion.

Homemade snow scooter with motor

Of course, such a model is interesting not only for children, but also for adults. But, since it is impossible to buy a snow scooter with a motor in a regular store, folk craftsmen figured out how to create such a machine with their own hands.

The resulting snow scooter with a motor is the result of combining a regular snow scooter with a motor board. Let us remind you that a motorboard is a board that is driven by an internal combustion engine installed on it. This is what is used as a motor.

This model of snow scooter can withstand a load of about 100 kg and reaches speeds of up to 20 km/h, provided there is a well-rolled path with compacted snow. The disadvantage is the difficulty of moving through loose snow and a weak battery, which lasts for 30-40 minutes of use.

An additional advantage of such a “toy” is the ability to disassemble it if necessary and use the snow scooter for its intended purpose. As for the motor, it can also be used in the summer by connecting it to a bicycle.

However, not everyone can make such a design. So, as an alternative, you can buy a snowmobile. You can buy this vehicle in our online store.

Snowmobile for adults

Snowmobile - a machine for moving on snow

A snowmobile is an excellent means of transportation in snowy areas. Snowmobiles are used by athletes, winter walkers, and fishermen. Models of snowmobiles are very diverse, and the less they weigh, the lower their carrying capacity and engine power.

In our online store you can find the Buran snowmobile, Patron Snowfox 80 snowmobile, ABM Wind 4T JS-150-G snowmobile.

How to make a snowmobile from a chainsaw with your own hands?

The very first step when assembling a snowmobile with your own hands should be to develop a drawing and diagram. So, you will see what spare parts and parts you can get from where, what you need to assemble, buy, and so on.

Next, you need to disassemble the selected chainsaw, prepare other components, fasteners, components and spare parts. This way the work will not stand still, and all the necessary parts will be at hand. For additional information, you can watch a video on how to assemble a snowmobile from a chainsaw with your own hands. This way you will have a better understanding of the design and structure of your homemade machine.

Rework principle

The principle of alteration is very simple and combines the entire range of home-made devices and assemblies. A chainsaw is used as a drive. The unique qualities of the chainsaw motor, capable of operating at very large tilt angles, perhaps not upside down, allows this universal drive to be used in many designs. In the case of using a chainsaw as a drive for a homemade hand-held power tool, most of the parts of the original chainsaw are retained, and only the working part is changed.

Walk-behind tractor from a chainsaw

If, on the basis of a chainsaw, you make a stationary machine or vehicle with your own hands, the alteration becomes deeper. A gearbox, variator or belt drive is added to the design, the fuel tank is replaced with a more capacious one to ensure long-term operation without refueling.

Which chainsaw is suitable for these purposes?

In order to make your own snowmobile from a chainsaw, you will need, in fact, a saw. You can take any brand and model that is in stock. Craftsmen recommend using the Druzhba, Ural or Shtil saws, as they are most suitable in terms of technical characteristics and differ in the quality of their engines.

Friendship

The advantage of the Druzhba saw is its simplicity of design and therefore it is very convenient to disassemble. In addition, the tool does not have any unnecessary bells and whistles that modern saws can boast of and which only interfere with the assembly of the snowmobile. But there are also disadvantages - the Soviet saw is heavy and outdated.

Chainsaw Friendship

Its technical characteristics are as follows:

• power – 1 kW;
• weight - up to 12 kg;
• engine (two-stroke);
• tire length – 45 cm;
• fuel (gasoline).

Ural

The excellent technical qualities of the Ural professional saw are perfectly suited for creating a homemade snowmobile on its basis. The mechanism is powerful and efficient, and is also adapted for use in cold conditions.

Chainsaw Ural

Technical data

• engine (gasoline, two-stroke, single-cylinder);
• power – 3.68 kW;
• weight – 11.7 kg;
• parameters – 46 x 88 x 46 cm.

Calm

The Shtil chainsaw also has sufficient characteristics to be used in a homemade snow scooter design. The most important thing is that the chainsaw has enough power to start the snowmobile. In addition, the Shtilevsky engine is characterized by quiet operation, which will give additional comfort to movement.

Chainsaw Stihl MS 180

What skills are needed?

You don’t need any special skills to assemble a homemade snowmobile, but it is advisable to know how to work with welding and have a welding machine. To use the diagrams and drawings provided, it is advisable to be able to understand them.

Tips for use

It’s worth immediately noting that a homemade design, no matter what it is, is unlikely to be registered (legalized) with the relevant authorities. And therefore:

1. According to the law, a homemade snowmobile does not belong to the category of vehicles. Therefore, its further use, as well as responsibility for the consequences, rests solely with the person who made it. It is better if it is operated somewhere in the outback and does not come to the attention of the relevant services.
2. A snowmobile and an amphibious all-terrain vehicle are completely different vehicles, although they have certain similarities.
3. Since the engine has low power, it is not advisable to transport cargo with this vehicle. It's better to travel alone.
4. To travel at night, you can install lighting (headlights) on your snowmobile. This will increase the functionality of the device and comfort when moving.

Chainsaw snowmobile

Before you start making a snowmobile from a chainsaw, you need to choose equipment that will have all the necessary characteristics. The best option for this purpose is the Druzhba, Ural and Shtil chainsaw (the power of these tools is ideal for creating high-speed snowmobiles).

Important! The engine and gearbox are the main parts of the chainsaw that are used during operation. The snowmobile design consists of four parts:

The snowmobile design consists of four parts:

The assembly of a homemade snowmobile is carried out not according to some proposed scheme or standard drawing, but based on the materials and tools that the master has at his disposal.

Instructions for assembling a snowmobile from a chainsaw

Assembling a product is quite an interesting job. It consists of several successive steps that must be performed carefully and responsibly.

The first stage is the assembly of the frame base of the future homemade snowmobile. For work you will need steel corners (size - 50 x 36 cm) or steel sheets (thickness - at least 2 mm). The middle part of the structure is made from the corners, and the front and back are made from sheets.

Carefully make two through holes to accommodate the track shaft and track wheel guides (tensioners are installed on both sides of the side members).

Important! The front device is specifically designed to tension the second stage of the idler gear, it also helps in adjusting the track itself

• Special brackets are carefully welded to the bottom of the side members (they are attached at the same distance from each other), support rollers are installed in their open grooves.
• The rollers (in rubber covers) are placed on five axes, each of which is attached to the underside of the open grooves.
• Between each of the elements special bushings made of duralumin are installed (they are made from a suitable pipe).

• The bracket axles themselves are secured using nuts and locknuts (they are designed to strengthen the snowmobile frame and hold the side members at a certain distance from each other).
• Three metal corners are used to make racks for attaching the prepared chainsaw gearbox, and install the intermediate shaft of the chain drive.
• A seat for the user is installed on the prepared frame (a suitable box or car seat is used for these purposes), it is fixed in the area between the middle and rear parts of the structure.

• A hole is made in the front section of the frame to accommodate the steering wheel; it is made from a pipe with welded control handles.
• Metal gussets are installed in the places where the snowmobile racks are attached (they strengthen the structure, make it stronger and more reliable).

Important! In order for the future homemade snowmobile to have good maneuverability in snowy terrain, it is equipped with a caterpillar mechanism

• A snowmobile drive shaft is made from a metal pipe, and a special round flange is inserted into it for attaching gears.
• To create the steering, equipment from old motorcycles or mopeds with three-lever control is used.

The finished snowmobile is light in weight and can easily be placed in the trunk of a car for transportation over long distances. Its controls are so simple and intuitive that even a child can easily use it.

Manufacturing

To assemble a homemade snowmobile from a snow scooter, you can also use parts of a cordless screwdriver. The complete set of parts in this case, in addition to the snow scooter and screwdriver, also includes:

• bicycle chain and sprockets;
• the steering wheel, cable and brake handle are also for bicycles;
• suitable nuts and bolts;
• pipe made of duralumin grade D16;
• two bearings with a diameter of 16 mm and one - 10 mm;
• a pair of plugs for plastic pipes;
• aluminum profile in the shape of the letter “P”;
• steel profile pipe 20x20 mm.

The first step to making a snowmobile out of a child's or adult's snowmobile is to replace the standard plastic steering wheel with a bicycle steering wheel. A trolley frame is welded on the basis of a profile pipe. After this, the shaft and drive wheel are grasped.

On the reverse side you will need to weld a wide washer onto the shaft. After drilling the holes, attach the wheel to it (with the same bolts). The bearings are fastened along their outer diameter using pieces of pipe. A screwdriver connected to a small star is attached to the bottom of the trolley frame. The space between the sprockets is used to tension the bicycle chain.

A snowmobile created using this scheme with your own hands is quite simple and convenient. The steering handle helps influence driving speed. The cable is secured using a bracket as close as possible to the start button. Power for the electric motor will be provided by any battery with a voltage of 12 V. It is easy to remove the cart if necessary, which simplifies the transportation of the snowmobile in the luggage compartment.

An alternative solution is a snowmobile made from a snow scooter with a trimmer engine. The frame is assembled using a steel profile and angles. Usually the frame resembles a rectangle, and its optimal dimensions are 1.5 x 0.4 m. The steering beam is assembled from metal corners and then sheathed with steel plates. They have grooves of a special design that simplify the fastening device.

A strong corner is placed on the front crossbar. Then they attach the seat and drill the side members. The engine is disassembled after installing the transmission and sprocket.

It is also useful to study general drawings of snowmobiles. The diagram below shows a model with a 78 cm wheel center distance. The total length of the vehicle is 1.65 m.

You can also use the following detailed layout diagram (at least to search for individual design solutions). You just need to take into account that this option is designed for people with decent technical knowledge.

How to make a snowmobile from a chainsaw

The snowmobile is manufactured according to one of 2 schemes:

• single-track (2 skis in front, 1 track in back);
• two-track (1 ski in front, 2 tracks in back).

Any snowmobile device has the following design:

1. Engine.
2. Supply system.
3. Oil injection system.
4. Transmission.
5. Chassis.
6. Steering.
7. Frame.
8. Electrical equipment.

Before you begin making a homemade snowmobile from a chainsaw and its further assembly, you need to design drawings of all working components and the general appearance of the vehicle. It is better to draw each assembly unit separately and take out the dimensions.

During the development process, the brand of gasoline tool is taken into account.

Models such as Druzhba, Ural and Shtil are well suited.

The Druzhba chain saw has a simple design. The disadvantage is the low motor power (1 kW) with a large mass of the tool (12 kg).

The Ural has a weight of 11.7 kg and an engine power of 3.68 kW.

• ability to work at low temperatures;
• high environmental friendliness.

When making a snowmobile from a chainsaw with your own hands, you can choose the Shtil brand. It is characterized by noiselessness during operation, a power of 1.5 kW, and has a nominal weight of only 3.9 kg.

The initial stage is the manufacture of the base of the frame structure from welded spars. For the middle part, corners 50x63 mm made of hardened steel are used, the front and rear are made of S2 steel with a flange at an angle of 90°. All elements must have holes of the same diameter for mounting with the track wheel and drive shaft. Brackets for road wheels are welded to the bottom of the frame.

The racks are made from 30x30 mm corners and connected by metal crossbars. The result should be a structure in the form of a small portal. A platform is required for the mounting location of the chain saw gearbox and the chain drive shaft. Sheet steel of the required size is selected, usually 2-3 mm thick, and welded to the center of the right side of the module and the portal.

At the back of the portal and at the same time in the middle of the module, a place is formed for the seat, which is subsequently made from boards and fabric or removed ready-made from old equipment, for example, a moped.

The front spar and the drive axle traverse are installed to the beam, which is a standard water pipe with a radius of 0.75 mm. Steering ski bushings are welded at both ends, and a stand for the engine subframe is welded in the center. The mounting points for the supports are reinforced with 2-mm metal gussets for strength and stability of the structure.

The mechanism from the Buran unit is used as a caterpillar, the belt is shortened by 0.75-1 m. The gears of the gear drive are planted on the transverse shafts, then the web is laid. The caterpillar gear is made from a nylon sheet measuring 15 mm.

Drive shaft

To make the drive shaft, a metal pipe with a diameter of 14 mm is taken, and flanges are installed on top to fix the wheel teeth. At the ends of the mechanism, pin tips are pressed in and welded with space provided for bearings.

The snowmobile engine is the most important component that affects the operation of all self-propelled equipment. Therefore, experts recommend using a power plant from a Shtil chainsaw with an engine power of 1.5-3 kW. The motor is mounted on a stable support of the cross beam. The gearbox is rotated 180°, fixed on the platform, and the intermediate shaft of the 2-speed transmission is also mounted. The fuel tank is installed on top.

The drive sprocket with an internal key made of St20 is attached to the shaft with an M12 nut and a spring washer. For precise fixation, a thread of the required parameter is cut on the tip. It is taken into account that the 1st transmission stage corresponds to a large sprocket with the maximum gear ratio (on the Ural engine there are 38 teeth), the 2nd stage corresponds to a small drive sprocket with 10 teeth.

The chains are of a standard type, with a pitch of about 16 mm.

Brake system

If the snowmobile is designed to travel at low speeds of up to 30 km/h, then the braking system may not be provided. Vehicles are stopped by friction in the chassis and transmission systems.

Steering

Control - steering on support-steering skis. The support arms are rigidly connected to the steering shaft bipod. The steering wheel is two-handed, with a gas handle mounted on the right side.

Components

Particular attention should be paid to the component parts.

The engine is the most important part of the mechanism and is selected with special attention. Its condition must not only be working, but it itself must be installed after maintenance. The gearbox must also be in good condition.

Sprockets are elements for transmitting translational motion from the engine. You need to create a tip on the right that is longer than on the left.

The steering is suitable for a scooter, moped or bicycle. The most important thing is to connect the engine to the steering part correctly.

The brake system is not provided for in the presented diagrams, but it can be made. However, first think about whether it’s worth racking your brains over this, because motor sleighs do not develop high speeds.

Principle, device diagram, theory, how everything should work out

All work begins with a plan and drawings, which can then be relied upon. Diagrams and drawings will be required in order to take into account all the components and their location, the relationship between each other and the operation of the mechanism as a whole. Pay close attention to the location of each unit, as if you make a mistake, the snowmobile simply will not move.

Work plan:

1. First, the chainsaw motor is attached to the made frame.
2. Skis are installed in the steering part of the snow scooter, which are the main element of movement.
3. Then the steering is installed.
4. To set the mechanism in motion, it is necessary to install tracks at the rear.
5. Connect the track disk and the chainsaw motor sprocket.
6. Finally, the driver’s seat is installed, which is mounted on a specially equipped place.

To equip the steering on a snowmobile, borrow the handlebars from a moped or bicycle. The main task will be to properly secure the steering wheel so that when you turn, the skis also turn.

Engine

This unit is considered the most critical mechanism of a snowmobile. Compared to other structural elements, such as a tire or chain, the engine must work properly and without it the snowmobile will not even move. Therefore, the long-term performance of the device will depend on the reliable and trouble-free operation of the engine. If you want to install an engine from an imported chainsaw, you can purchase a used Shtil.

Another important design element on which the trouble-free operation of a snowmobile depends is the gearbox.

Asterisks

Immediately noticeable is the fact that the right tip has a keyway for installing and securing the chain sprocket. This is the track shaft sprocket, which is securely fastened with a nut. To make fastening possible, a corresponding thread is cut on the tip.

The tip of the tension shaft has the same overall dimensions, and the fastening of the structural elements is carried out similarly to the fastening of the track shaft sprocket.

The first gear stage should have a sprocket with the highest gear ratio (number of teeth). The Ural chainsaw engine has 38 teeth.

Steering

On a homemade device, you can install a handlebar of any design, even a bicycle. In this case, it is very important to put manual control of engine speed on the steering wheel. In order not to bother too much, it is better to use a steering wheel from a moped, scooter, etc., which already has a mechanism for controlling engine power. This will make the design more reliable and easier to manage.
