The overall layout and some ideas about the design of these devices we have already considered and. It is time to talk about whether it is possible to reduce the size of the device. In other words, we will examine how to do with your own hands mini snowmobiles. The video that will be presented in this article will help you visually imagine the whole design.
Let's start the review with such an interesting model:
With the exception of one detail, everything else in this mini snowmobile is done with their own hands. How? About this in detail tells the video:
As you can see, the running part is dismantled in detail. The original system of soils, it is worth noticeing and, possibly, take up.
It is of interest and such a decision:
This snowmobile, though mini, but, as can be seen from the photo, may be single, and double.
Distinctive features: Motor engine (6 hp), PVC PVC PVC Tubes are fixed on the conveyor belt, driven stars were removed from a snowmobile "Buran", skiing from "Argomak" (Children's snow scooter), frame length - 2000 mm, mid-scene The distance rinks - 1070 mm, the width of the caterpillars - 470 mm, all the device assembly weighs about 80 kg.
This design mini snowmobile is curious:
It is noteworthy in that the engine is taken from the motor-pump (163 m³), \u200b\u200bthe automatic adjustment is simply blocked by a wire ring.
But such an interesting apparatus may turn out of a scooter or moped:
In fact, we have simply replaceable module in a mini snowmobile.
It is clear that just like that, from the bay-junction, a decent mini snowmobile don't do it. It is necessary that these most hands from the right place grew, we need an increase in, plumbing skills, knowledge of physics in the end (at least in the amount of high school). But, agreed when ready, structured independently, will normally go through the snow - this is cool.
Received information will help to avoid the most common mistakes. Ribbon, by the way, you need to take a frost-resistant, otherwise there may be problems at low temperatures.
How to dock the caterpillar? Two ways.
- In the junction We cut the tape on the primer, we cut it with a flush with a ribbon, carefully we connect, install the brackets to the place (conveyor belt lining).
- Vangest (the easiest way). We cut the tape in the right place, connect the bolts (up to six pieces).
Snowmobile is a very practical and useful thing that is necessarily useful in the snow edges. The factory snowmobile costs a lot of money, but it can be done independently.
This article is intended for persons over 18 years

Snowmobile do it yourself - it is real
As they say, if a person has hands grow, where it is necessary, he will cope with any task. To such a master, give a plain engine and soon he will make a boat, tractor, a fiberboard or a snowmobile. Since in many cities and towns of Russia, the snow lies for several months, then the creation of snowmobiles is a matter of very relevant. Today we will tell you how to make a homemade snowmobile at home.
It is only at first glance it seems that everything is too difficult, you just need to have skills and many girlfriends. The main thing, be prepared to spend a few days to work, but the result will definitely cost that. Snowmobiles homemakes are not inferior to factory models, perfectly feel in deep and loose snow, do not break and do not wear out.
There are no specific rules from what a homemade snowmobile must be made. On the Internet you can find certain drawings, sizes and schemes. It may be an ordinary simple snowmobile with one or two caterpillars, on wheels and so on.
The guys who managed to make a miracle car, gladly share their experience and impressions from the snowmobile creation process. But the secret is to use those materials that you have at hand. You can take a motor from a motoblock, a headlight from something else, a hood from under the old car, and so on.
If we are talking about a mini-snowmobile, which is a budget option, it can be easily made it possible for two weekends. To do this, use a homemade caterpillar that can be easily made from the conveyor belt. In the role of primrates, you can use any materials, including plastic water pipes. Do not worry, already checked by masters that plastic pipes normally feel with severe frosts.
1) Crawler Snowmobile Must be as easy as possible, then he will be able to overcome even the most loose and deep snow without any problems. Since we started talking about such a model of a snowmobile, then some details should be clarified. Although the design is pretty simple, but reliable.
How is a fellows in a hanger? First we make four wheels inside the conveyor belt, they will roll directly on the tape, which also attached plastic primers. In general, the scheme of movement of a kind of technique is understandable. The engine can be taken from the motoblock, but it is only as an option. Use what you have at your hands.
Now a few words about how to make proper plastic pipes. First, the plumbing pipe is cut into the same blanks. Their size depends on the dimensions of the future snowmobile. Each blank is separated by a circular to two identical parts. There is a special device that allows you to calmly cut plastic pipes. Thanks to him, it turned out even and beautiful "sticks" in the role of soils. You can attach them to the tape using special bolts.
A very important point so that there is the same distance between the primers. Otherwise, they will simply stick on each other, thereby shoot down the caterpillar.
You need to drill the conveyor belt using a special conductor. In the store you can purchase small rubber wheels, driven stars for caterpillar and bearings. Skis can be used from any kindergarte. This snowmobile is considered collapsible, because it is spent on its assembly no more than half an hour. Therefore, it will be more profitable, after the end of the winter season, disassemble the design. A two-metering snowmobile is already a more complex model, but it is also really easy to make it manually.
2) Wheel Snowmobile - A rather original structure, it is also called pneumatics. In other words, this is a tiny tractor with very unusual wheels. You can make such equipment from a motorcycle, a motoblock. The design safely overcomes loose deep snow, because there is a large area for contact with the surface.
3) Electricity You can also do yourself. But since you decided to make an electric snowmobile, then forget about lithium and polymer batteries. They are simply unreliable for frosty weather and will require constant replacement. It is best to stop the choice on lead. You can make a steeplyelectro snowmobile for a child. Voltage at 12 volts is the norm. Surely, everyone saw or carefully studied the model of a snowmobile amphibian. Some ideas can be taken from this well-known design. The time of making a real homemade self-like: from two days and up to the week. It all depends on the presence of the desired details, as well as your free time. Try forever to calculate everything to the smallest detail, so that there were no problems in the process of work.
Making a snowmobile from a motoroblock with your own hands
We have already said that it is possible to make a snowmobile from almost any girlfriend materials from:
- chainsaws;
- motorcycle (Izh, Planets 5, Jupiter 5, Dnipro, Minsk);
- snow scooter;
- scooter;
- bicycle;
- car (Niva, Zaporozhets);
- moped (from ant, alpha);
- saws;
- tires;
- motorists;
- screwdriver;
- cultivator (motorcultivator, crotis);
- trimmer (benzotrimer);
- lawn mowers;
- snow scootar margame;
- motorBastor.
This list can be continued forever. But this does not mean that all the details or base is taken from one particular subject of technology. Often, the donor serves only for a small goal (frame, engine, ski).
We will not consider the step-by-step instructions for making a snowmobile from various techniques. We will analyze only the model from the motoblock on pneumatics (without the use of the caterpillar) with their own hands.
Since there is no caterpillar, then repairing the construction will be much easier. You will need: pipes for the frame, the corner of steel to strengthen the entire structure, we only take a power plant from the donor. To make the wheels, you need to use the cameras of impressive sizes. Excellent suitable from any large agricultural machinery. From the VAZ (not necessarily 2106) you can take the gearbox and part of the chassis. Also do not forget about a drill, a grinder and, of course, the welding machine.
All important snowmobile elements will be hidden inside the frame. We need a pipe in order to make a power frame. Calculate that the power of the motor is more or less suitable for wheels of a similar diameter.
A few words about how the transmission in snowmobiles from the motor-block is carried out. There are several options. The first (regular gearbox) is not the most optimal, because for switching requires a complete stop of the design. If possible, instead of the gearbox, you can put the gearbox from the old car.
So, the snowmobile from the motoblocks quickly became popular and something resembles a primitive car. After all, the transfer can be switched without stopping, on the first and second gear you can safely wade through any roads. The third and fourth will allow you to slowly ride along the already rolling trace.
For convenience of moving in the dark, do not be lazy to install tractor headlights, as well as a car generator. In general, this transport will not be comfortable more than two people. If you want to ride the company, then take care of the trailer.
But it is impossible about speed and think. After all, your vehicle is not equipped with elastic elements and shock absorbers. Pneumatics will give themselves to know at speed. In addition, there is no cab cabin, and a strong wind with quick ride will immediately give himself a felt.
Some of the most famous models of snowmobiles, such as: Buran, Lynx, Taiga, Tiksi - were equipped with a Lifan engine. A good engine can be borrowed from the eye.
Snowmobile is quite simple in the fabrication of transport, which will help freely move in a snowy area. This is a kind of SUV. Therefore, do not be lazy to make equipment with your own hands, if you are lucky enough to stay in the zone of frequent snow. Carefully make a scheme of action and everything will be done!
Once people see snowmobile prices in the store, then ask a question how to make a snowmobile snowmobile yourself, how expensive is it expensive? How starts the manufacture of homemade - a snowmobile snowmobile? Initially, it is necessary to determine which power the engine is used. We used the engine of the motoblock in 6 horsepower. Usually, four-stroke engines with forced air or water cooling are installed on the motoblocks.
Motoblock can also be used reverse gearbox, centrifugal clutch, steering and fuel tank. Next, you need to consider the snowmobile propulsion. The tracked drive is installed on most of them.
Best Homemade - Motoblock Snowmobile
In the manufacture of a self-made snowmobile, caterpillars from other snowpots are used for it, or homemade, collected from undergraduated materials. After selecting the caterpillar, it is necessary to determine which type of suspension to use. It is necessary to choose from two main species: suspension on rollers and sewing suspension.
Each of them has both advantages and disadvantages. After that it is important to decide which snowmobile will be a layout. Usually, there are two steering skiing in front of the snowmobile and behind the tracked block.
The engine can be installed both from behind and in front of the snowmobile.
How to make a snowmobile snowmobile yourself
This snowmobile can be done in a few weekends at the cottage in the garage. At first glance, his design looks very simple. If you compare its permeability in the wet or loose snow, it will not give way to many industrial snowmates.
Creating a snowmobile proceeded from the principle: the less weight and more the size of the caterpillar, the higher its permeability of deep and loose snow. Therefore, the design will be the easiest.
How to make a homemade snowmobile from a motor-block on caterpillars
Four wheels are installed inside the caterpillar. When the movement occurs, they roll along the conveyor belt, with fixed plants. The caterpillar drive is carried out by a chain from the motor, special leading asterisks, through the slave shaft. They were removed from Buran.
The engine is taken from the usual motor-block, the power of which is 6 hp Quickly on it will not be attended. Soft suspension skiing and caterpillars was removed, because the snowmobile is designed for riding in a loose snow. This design was simplified and reduced snowmobile mass.
Making Cateries for Snowmobile
Consider the process of making the caterpillar. The plastic plumbing pipe is 40 mm, cuts a long 470 mm. Of these, billets will be made for soils. After that, each of them is crucified along the equal parts with a circular saw.
The soils are attached to the furniture bolts to the conveyor belt. When the caterpillar is manufactured, it is extremely important to maintain the same distance between the soils. Otherwise, the "incision" on the progress of the lead sprocket will occur, as a result of which the caterpillar will slip and slides from the rinks.
To drill holes in the conveyor belt for fastening bolts, conductor was made. For drilling holes, a tree drill was used, having a special sharpening.
This conductor allows you to drill six holes at the same time in the conveyor ribbon to attach three caterpillar primer. Leading asterisks were also purchased (2 pcs), inflatable rubber wheel (4 pieces), closed bearings №205 (2 pcs).
Tokar made a support for bearings and the leading shaft of the caterpillars. Rama snowmobile is made independently. For this purpose, square pipes 25x25 mm are used. Hinged axis of rotation of the steering wheel and skis are in the same plane and on the same line, so the continuous steering traction was used without ball lugs.
Pretty easily made ski rotation bushings. Pipe clutch, the internal thread of which is 3/4 inches, is boiled onto the front transverse beam. There are screwed nozzles with outdoor threads. They welded the thai skis rack and steering thrust. On skis are installed corners, which serve as an attachment to the rotting rack of the snowmobile. A metal line is made from below to better control snowmobile while driving on the rolled snow or an imaging.
Chain tension is regulated by the engine offset
Snowmobile control occurs quite simple. To increase the engine speed, the gase handle is used, which is located on the steering wheel. This includes an automatic centrifugal clutch, as a result of which the snowmobile begins to move. Since the engine power is small, then the snowmobile speed is 10-15 km / h. Therefore, the brakes are not provided. To stay, you need to reset the engine speed.
Caterpillars are made by any width. Choose what is more convenient to do: a narrow, but long caterpillar, or wide, but short. It is important to remember that a big caterpillar will load the engine more and complicate the snowmobile control. If the caterpillar makes a small one, then the car may fall into deep snow.
Snowmobile weight with all parts turned 76 kg. It includes: steering wheel and engine (25 kg), skis (5 kg), wheels with axes (9 kg), presenter shaft (7 kg), caterpillar (9 kg), seat with racks (6 kg).
You can reduce the weight of some details. For this size of a snowmobile with a caterpillar, the weight indicator is quite satisfactory.

Homemade Motoblock Snowmobile Video
Snowmobile - a unique vehicle for daily use in winter. It is used for movement in the snow-covered area during scientific expeditions, excursions, hiking, animal hunting, territory protection. Such a product can be purchased in a specialized store or make it yourself. If the finished structures have a rather high price, and not every person is able to afford such a purchase, then improvised - a more affordable alternative, made of well-made materials and equipment.
The homemade snowmobile can be made with their own hands from the available technique. For these purposes, experts recommend using:
- chainsaws;
- motoblocks;
- motorcycles.
Important! To make a portable snowmobile at home, be sure to have skills to work with plumbing tools.
Drawings, options for finished works
Snowmobile design must be started from creating a drawing of the desired product. It will help in the process of work to manufacture practical and functional equipment, which will serve not one year.
Option of finished work If you can use the finished drawings to create a snowmobile from a motor-block or a motorcycle, then for the design of chainsaws - they are not provided, since each tool has its own specifications and features.
Snowmobile from chainsaw
Council. Snowmobile can be made as caterpillar and ski.
Before proceeding with the production of a snowmobile from chainsaws, you must select the equipment that will have all the necessary characteristics. The optimal option for this purpose is a chainsaw "Friendship", "Ural" and "County" (the power of these tools is ideal for creating high-speed snowmobiles).
Important! The engine and gearbox are the main details of the chainsaws that are used in the process.
The snowmobile design consists of four parts:
- Caterpillars
- Transmissions.
- Engine.
Chainsaw Ural The homemade snowmobile assembly is made not on some kind of proposed scheme or standard drawing, but based on the materials and tools that are at the disposal of the wizard.
Snowmobile assembly instructions from chainsaws
Product assembly is a fairly interesting job. It consists of several consecutive stages that must be accurate and responsible.
- The first stage is the assembly of the frame base of the future homemade snowmobile. Steel corners will be required to work (size - 50 x 36 cm) or steel sheets (thickness - at least 2 mm). From the corners make the middle part of the structure, and from the sheets - the front and rear.
Council. To give the necessary stiffness of the structure, the metal is bend under angle of 90 degrees.
- Carefully make two cross-cutting holes for placing the shaft of the tracked mechanism and the guide devices of the tracked wheels (the tensioning devices are installed on both sides of the spars).
Important! The front structure is specifically designed to tension the second stagnation stage, it also helps in adjusting the caterpillar itself.
- Special brackets are neatly welded to the bottom of the spars (they are attached to the same distance from each other), in their open grooves and set the support rollers.
- Rollers (in rubber covers) are located on five axes, each of which is attached from the bottom side of the open grooves.
- Between each of the elements, special sleeves from duralumin (they are made of a suitable pipe).
Council. In order not to spend time on the manufacture of rollers and axes for them, they can be borrowed from the old equipment for digging potatoes.
- The axis of the brackets themselves are fixed using nuts and monitoring (they are designed to enhance the snowmobile frame, keep spars at a certain distance from each other).
- Of the three metal corners make racks for fastening the trained gearbox gearbox, the intermediate shaft of the chain transmission is installed.
- The prepared frame is installed for the user for the user (for these purposes a suitable box or car seat is used), it is fixed on the site between the middle and the rear part of the structure.
Snowmobile from chainsaw - On the front area of \u200b\u200bthe frame make a hole for placing the steering wheel, it makes it from the pipe with welded handles of control.
- In places of attachment of snowmobile racks, metal brazers are installed (they strengthen the design, make it more durable and reliable).
Important! In order for the future homemade snowmobile to have a good passability of snow-covered terrain, it is equipped with a caterpillar mechanism.
- A snowmobile drive shaft is made from the metal pipe, a special round flange is inserted into it for fastening gear wheels.
- To create a steering, use equipment from old motorcycles or threshing mopeds.
The finished snowmobile has a small weight, easily placed in the trunk of the car for transportation over long distances. His management is so simple and clear that even a child can easily use it.
Snowmobile from Motoblok.
Motoblock is another version of the equipment that is used in the process of making a snowmobile with your own hands. Its design is practically no need to redo, as it is initially multifunctional.
There are three types of motoblock snowmobiles:
- wheeled;
- on caterpillars;
- combined.
Motobl Before starting working with a fiberboard, it is necessary to determine the type of future design. From him and will depend on the complexity of the work of the master, as well as the duration of the whole process.
Construction of a snowmobile from a motoblock
Important! To create a wheeled snowmobile, you do not need to redo the steering system, you need to pay special attention only to the frame of the device and ski.
- The snowmobile frame is made of metal pipes or corners (it must have a rectangle shape).
- The finished base attach a box or a chair to place the driver.
- Separately make skis from corners and sheet metal, weld them to the frame.
- The finished design is attached to the motoblock, used by destination.
Drawing: Motoblock Snowmobile Motorcycle Snowmobile: Masters Guide
Make a snowmobile from a motorcycle is not so simple. If the assembly of previous products is practically no difficulty, then with this design will have to suffer. It will require not only tools, materials and techniques, but also skills in working with a welding machine and other equipment.
Important! Motorcycles "Ural", "Izh" and "Dnipro" - the most suitable models for making a snowmobile with their own hands.
Snowmobile design technology
- Make a suitable frame from metal pipes of different diameters and steel corners. It is performed in the form of a rectangle (its dimensions - 150 x 43.2 cm).
- Construct a steering beam made of metal angles (its dimensions - 50 x 50 x 5 mm), its parts are trimmed with dense metal lining. The finished design is installed in a horizontal position on a drilling machine.
Motorcycle IZH - Frame and ready-made beam are treated in places of compound, prepare special grooves for reliable fixation of elements.
- The front frame of the frame is equipped with a solid corner.
- Fasten the seat to the frame frame.
- Make holes in spars.
- Between the steering and middle section welded a channel.
- Pick up a suitable tracked asterisk and rubber tape for further installation (suitable dimensions - 2200 x 300 mm, thickness - no more than 10 mm).
- The caterpillar itself is gently crumbling, so that the material does not resolve in the process of use.
Motorcycle snowmobile - Install the transmission that consists of the front and rear axle. The front is the presenter, it consists of a tubular shaft, caterpillar stars and rinks (the asterisks themselves are fixed on through bolts). The design of the rear axle consists of a tracked drum and a tubular shaft.
- Skis welded to the design of a snowmobile (for their manufacture, steel sheets and metal corners are used).
The control system of a self-made snowmobile from a motorcycle is quite complex in design. It consists of:
- longitudinal traction;
- transverse thrust.
From the presented information, we can conclude: the homemade snowmobile from the elements of the motoblock, chainsaws or a motorcycle - reality. It can make every wisp master. For productive work, only certain skills, equipment, tools and materials will be required.
Homemade Snowmobile: Video
In many regions of Russia, the only means of movement is snowmobile. However, in the times of the financial crisis, not everyone can afford to purchase expensive technique. Why not remember the possibilities of the self-made designer with a universal motor installation "Maew", which will make a snowmobile with their own hands.
Our snowmobile consists of two parts. The first - led by - relies on the crawling in the form of a ski with a seat for the driver. The second is the master - consists of the Motor Installation "Mind" with a wheel drive. Both parts of the snowmobile are connected by a vertical hinge, which allows them to take various angular positions relative to each other.
The slave part includes a carrier frame with driver seat and control levers. It hinge reluctantly on the staples of the poloz. With a turning rack, the carrier frame is fastened hard.
Poles are a pair of wide wooden skis, parallel to interconnected. In the middle part of each skiing staples of hinged connections.
In the frame design, the attachment places of the removable foot platform equipped with brake pedals are provided.
Snowmobile control levers are connected by a single sleeve and fixed by screws under the driver seat.
Rubber tips are put on the knobs of the levers. The right handle is equipped with a cable gas adjustment mechanism from a serial motorcycle.
Steering thrust will have to make themselves. The thin-walled steel tubes with a diameter of 16 ... 18 mm are suitable. At their ends it is necessary to install connecting hinges capable of working in two angular planes.
In the second part of the snowmobile there is a leading bridge with homemade low pressure wheels. The best solution is to apply pneumocamera from cars; In the inflated state, their outer diameter is approximately 80 mm.
Produce a carrier frame (see Fig. 2) The slave of the snowmobile is best of all of the steel thin-walled pipe with a diameter of 40 mm. Bend the pipe of such a diameter without a special device is difficult, so the swivel rack of the frame in its lower part will have to be collected from two straight pieces. If there is still an opportunity to quickly bend the pipe without disturbing its cross section in the bend, we advise you to start making a slave frame from this operation.
Fig. 2. The design of the carrier frame
1 - Rotary Stand, 2 - Loose beam, 3 - arm of the axis of the levers, A - the size of the central part, b - the general view of the carrier frame.
Hacking for metal Cut the remaining tubular blanks. Connection locations will be described by a semicircular file. Put the turning rack with a curved (or welded) end on a smooth horizontal surface (concrete floor) and grab the gas or electric welding parts. Make sure that all the grateed frame parts are strictly in the same plane. To do this, stick the pipe along the entire length with the hammer. Only after this operation, connect all the details with each other.
The next step is the manufacture of flanges and plates of the support beam. One of the finished flanges will breed to the end of the support beam, observing perpendicularity to the axis of the pipe. Put two plates on the beam and breed the second flange to the opposite end, observing the alignment of the holes in both flanges. To install the reference beam on the carrier frame, grab the welding of the fold from the two sides, as shown in Figure 2.
Make sure the beam relative to the frame plane is taken perpendicular.
After that, brew a clamp. Make sure that the beam is freely moving along its axis and simultaneously rotates in the plated. By moving the beam along the axis, pick up such a position so that the distance from the planes to the flanges was the same both on the left and right. Mark this position by risks.
Now, according to Figure 2, exhibit the angle of the flange so that the loose holes look strictly down. Once again, check the position of the rice and take the welding pipe of the beam to the plated. Swipe the final adjustment and only after that the weld of the seam is completely.
No detailed descriptions are required to set the axis of the axis axis of the levers. It is much more difficult to install the brackets of the swivel axis, this work takes place extremely carefully, because here it is necessary to withstand the maximum accuracy in the alignment of the holes between themselves, as well as the location of the plane of the centers of these holes with the center of the rotary rack and the axis of the average frame segment.
The frame assembly completes the addition of welding seat brackets and stiffery brazers.
For the ski pair (see Fig. 3) you will need to make two identical struts, two identical bracket with axes and actually a pair of skis.
Fig. 3. General view of the ski pair
Fig. 4. Control details
1 - left control lever, 2 - fastening the control lever, 3 - lever sleeve, 4 - End Details of the hinge (8 pcs.), 5 - Central Details of the Hinge (4 PCS)
As for the strut, they will have to cut from a pipe segment with a diameter of 22 mm. To them, weld the corner of sheet steel with a thickness of 3 mm. The brackets will have to bend from the same steel, and the axis is to sharpen on the lathe.
Skiing is best made independently of 3-mm plywood sheets in 9 or 10 layers. The best glue is epoxy resin. Cut the drying on the mandrel with the use of powerful clamps. More information about this operation can be read in Levershem No. 12 for 1997 (article "On the snow, like on asphalt").
Levers and control thrust (see Fig. 4) are simple in design, even though the process of their manufacture will require welding and turning works. Much attention is paid to the accuracy of the execution of hinged pull. All Lufts Eliminate as an assembly.
Making a platform for legs, brake pedals and seats, we will not describe in detail - their design is understandable from Figure 5.
To connect the driven part of the snowmobile with the lead you need a rotary axis. Make it from the segment of the steel pipe with a diameter of 22 mm and a length of 140 mm. From one end, breed a square flange from sheet steel, and on the other end drill a hole for the stopper's stack. You will find the exact dimensions of the axis, the flange and the end washer on page 10 in the "Leftersha" No. 4 for 2008 - the lower part of the universal steering wheel.
By the way, from the same issue of the magazine, use the design of the leading bridge, taking it as a basis in your snowmobile, replacing only the flanges shown in Figure 6.
Fig. 5. Foot platform device
1 - Brake pedal, 2 - brake drive cable, 3 - platform, 4 - platform bracket, 5 - brake lever.
Fig. 6. Wheel flange
For the final assembly of the snowmobile, it is necessary to slightly modify the bracket by the footboard of the micromotocycle (see "Levshi" No. 9 for 2008), which is used to attach the rolted snowmobile. The improvement of the bracket is shown here in Figure 7.
Fig. 7. Connection of rotary

For the very comfortable snowmobile, the old moped will be required, welding and some scrap metal, to create a frame of the year.
As you can see from the photo, the main alteration is a ski installation instead of the front wheel and the manufacture of a surcharge with a ski support.
Skiing is better to purchase ready-made, all the same skis - this is the basis of a snowmobile, but if you do not work out, then you can make yourself from Durally. Just learn, Durally ordinary welding do not boil, you need argon. The one who claims that Dural does not boil - not right. Argon-and-arc welding can be easily welded in a duralant without disturbing its jum.
Motor mounting is also reworked under a broader snowmobile base. Here you can do by conventional metal corners and arc welding.
The drive wheel with primers is as easy to make independently. Transmission of rotation from the motor to the wheel - chain. Do not try to make huge soils, if at the time of the total gas dacha under the soil-made snowmate, frozen soil will fall, then there is a high probability that the chain is broken.
The muffler can be made with their own hands. Special qualities to reduce noise can not be achieved, rapidly by the dying engine of the engine of the homemade snowmobile bear, you still do not wake up, and other beasts will step up to contact the rumbling miracle.
Mopedovsky starts reworked on a manual start. All the same in the felt boots, run the twinkling lever to the foot is impossible.
A box cooked under a bedroom on a homemade snowmobile is good to use keys and spare parts for storage. But it is better to put a bottle of vodka in such a chest of snowmobile made with your own hands. In case you break the chain. Without vodka in the frost tight, and you can live with vodka.
As you can see - make a snowmobile with your own hands in the garage simple enough. It remains only to wish good luck to self-dealers who love to ride on the snowy plains of our homeland on homemade snowmobiles!
How to make a homemade snowmobile with your own hands: Scheme, photo and device
Such a homemade snowmobile was made in a few weeks with his own hands in his own garage. The device seems to be very simple, and it will be quite forces a variety of homemaged masters.
Several years ago, I made a snowmobile with a self-made caterpillar from conveyor tape and plastic water pipes for my nine-year-old daughter. At first I had doubts about the reliability of such a caterpillar and how plastic details in the cold would behave. But during the two-year winter operation, breakdowns and strong wear of the pipes did not happen. This inspired me to create a slight snowmobile for myself with the same homemade caterpillar.
In the photo at the top of the homemade tracked snowmobile - at the top of the single and below the double version.
Perfectly realizing that the smaller the snowmobile mass and the more the supporting area of \u200b\u200bthe caterpillar, the better his permeability on loose and deep snow, I tried to make the design as easy as possible.
The principle of snowmobile operation is very simple (Fig. 1). Four wheels are installed inside the caterpillar, which when moving rolls on the conveyor belt, on which the primatelates are fixed. And the drive of the caterpillage from the motor is carried out by chain through the slave shaft with special leading asterisks. I took them from the snowmobile "Buran".
With an engine from an ordinary motor-block with an automatic adhesion with a capacity of only 6 horsepower, you will not quickly get up quickly. I was going to ride on a snowmobile, not on the rigged tracks, but along the loose snow, so I refused the soft suspension of the caterpillar and skis to reduce the mass of the snowmobile and simplify the entire design.
Caterpillars for homemade snowmobile
First made a caterpillar. The plastic plumbing pipe with a cross section of 40 mm chopped on the blanks for soils with a length of 470 mm. Then each billet saw the circular along into two equal parts.
With the help of the device shown in Fig. 2, the saw saw on the tree cut along plastic pipes for soils.
Figure 1. Small snowmobile scheme
The primer attached to the conveyor belt with two furniture bolts 6 mm with a large semicircular hat. In the manufacture of the caterpillars it is very important to withstand the same distance between the soils, otherwise they will "dial" the leading stars and the caterpillar will begin to slip and slide from the rinks.

1. Wooden bar;
2. Plastic pipe;
3. Metal corner.
For drilling in the conveyor belt holes under the fastening bolts 6 mm made a conductor. The holes in the ribbon drilled the drill on a tree with a special sharpening.
Using such a conductor, 6 holes can be drilled in the conveyor tape at once for the attachment of the three cargoes of the caterpillar.
In the store I purchased four inflatable rubber wheels from the garden trolley, two leading stars from the snowmobile "Buran" and two closed bearing №205 for the leading shaft of the caterpillars.
Make the drive shaft of the caterpillar and bearings for bearings I asked Tokary. The snowmobile frame made himself from square pipes 25 × 25 mm.
Since the axis of the turns of the turn of the skis and the steering wheel are on the same line and in the same plane, you can use a continuous steering craving without ball lugs.
Ski rotation bushings are made easy. For the front transverse frame of the frame, I welded water clutches with an internal thread 3/4 inches. They screwed up the nozzles with an outdoor thread, which was attached to the welding of the tower steering thrust and ski racks.
I recommend using skis from the children's snow scooter "Argomak". They are easier and more elastic, but they need to install corners for fastening to the rotting rack of the snowmobile and the metal sub-cut - for better snowmobile control when driving in an imagination or rolled snow.
Adjusting the tension of the chain takes place due to the engine offset.
Snowmobile control is very simple. With increasing engine speed, the gas handle, located on the steering wheel, the automatic centrifugal clutch is turned on and the snowmobile starts movement. Since the estimated snowmobile speed is small (only about 10-15 km / h) and depends on the density of snow, the snowmobile brakes are not equipped. It is enough to reduce the engine turnover and the snowmobile stops.
I will share a few tips, which when repetition of this design may be useful
1. The pipe for the tracks I cut along the manual circular saw on the tree first on the one hand, then on the other. So it turns out to be even than to immediately cut both walls. More convenient to handle small blanks. If you immediately cut along a long tube, then in this case the plastic will melt and the saw disk will climb.
2. Caterpillars can make any width. And each constructor has the right to choose what is more convenient for it: make a wide, but short caterpillar or narrow and long. Just remember that with a big caterpillar, a snowmobile will be poorly controlled and the engine loads more, and with a small in a loose deep snow he may fall.
3. On some of my photos, it can be seen that plastic "barrels" are installed inside the caterpillar. These are the guides of the stops for the Scolation, which must prevent the caterpillars from the rinks. But in the process of exploitation of a snowmobile caterpillar and without Scolation did not slip from the rinks, so "barrels" can not be installed, which will reduce the mass of the snowmobile.
4. At the end of winter, I completely disassembled a snowmobile to determine its weight. The weight of his individual nodes was like this:
- caterpillar - 9 kg;
- presenter assembly - 7 kg;
- two pairs of wheels with axes - 9 kg;
- engine and steering wheel - 25 kg; pair ski -5 kg;
- rama-15 kg;
- double seats with racks - 6 kg.
Total weighs 76 kg together.
The weight of some details can be reduced. Nevertheless, the weighting rate for a snowmobile with the caterpillar of this size is quite satisfactory.
The geometric dimensions of my snowmobile are as follows: the length of the snowmobile frame - 2 m; The distance between the axes of the support wheels (rinks) is 107 cm; The width of the caterpillars - 47 cm. The step of the carriage of the caterpillar depends on the thickness of the transport ribbon and it is necessary to pick it up with an experienced way (I got 93 mm).
I do not bring the exact size and drawings of the snowmobile details, as everyone who will gather repeat the design, will focus on those details and components that can be purchased or making themselves.
In the photo, the stages of snowmobile manufacturing according to the above drawings schemes:
- Billets of the soils of the future caterpillar.
- Special leading stars from the snowmobile "Buran".
- Homemade trail of caterpillars with installed stars for chains and caterpillar.
- Conductor for drilling holes in the conveyor belt.
- Catering rollers with axes and attachment brackets to a snowmobile frame.
- The drive from the engine of the drive shaft of the caterpillars is carried out by a chain from a motorcycle.
- Snowmobile frame with the leading shaft and support rollers of the caterpillar.
- Ski rotation mechanism.
- At this snowmobile, I put plastic skis from children's Chinese Sanok. But the plastic, from which they are made, turned out to be very fragile and by the end of winter one of the skis broke down.
- Skiing from a snow scooter "Argomak" with a fixed line (skate) and fasteners for installation on a snowmobile.
- Ski turn bushings. Everything is very simple: no bearings. It is only necessary to put lubricant on the thread, and the long service life is provided. In addition, screwing or turning pipes, a snowmobile clearance can be changed.
- The axis of the front wheels (caterpillar rollers) is attached to the frame stationary, and the axis of the rear wheel rinks, rotating the bolt, can be moved to regulate the caterpillar tension.
