In the harsh Russian winter, it would be nice to have a snowmobile. Previously, such a car was a luxury, and it was possible to buy it only abroad. Today, this vehicle can be found in almost any motorcycle showroom. A snowmobile can be purchased just for fun (for winter fishing and hunting), sometimes you can’t do without it at work (rescuers, foresters, surveyors). The cost of a snowmobile depends on the manufacturer, modification, power and other factors. The most simple model can cost about 100,000 rubles, and the price of a more advanced snowmobile reaches 1,000,000 rubles. Of course, if this equipment is necessary for work, then it is not worth saving, because people's lives can depend on the reliability of a snowmobile, especially if it is operated by rescuers. But for fun, you can assemble this miracle machine at home.
Homemade snowmobile, any person more or less versed in technology can build. Before you start making a snowmobile, you need to understand what benefits you will get from it.
Advantages of self-assembly:
- Price. For some, this may be the biggest benefit. The price of a homemade snowmobile will cost several times cheaper than if you buy it in a store.
- Characteristics. When making a snow machine, you control the entire process yourself, choose the configuration, power and appearance.
- Reliability. By assembling the device yourself, you will use the best components and parts.
A well-made car with your own hands can be used not only in the city, it is quite safe to travel outside settlements, to ski resorts and travel off-road.
Where to begin?
It is best to start assembling the device with your own hands from the drawings. To create a drawing, engineering skills will not be superfluous. However, if you have not succeeded in this, then you should use the Internet and print the finished scheme. On the World Wide Web, it is possible to find drawings of snowmobiles of various modifications, from the simplest and cheapest options to complex ones that only an experienced mechanic can design. The drawings are in the public domain, by printing which you can easily build a dream car.
When studying the drawings, pay attention to the mass of the unit, the lighter it is, the higher its permeability will be. The snowmobile will easily maneuver through loose and deep snow. However, not only the mass of the finished product affects the patency, the bearing area of the caterpillar is no less important.
What is a snowmobile made of?
Any snowmobile consists of basic parts that will not change regardless of the modification of the device, such as:
- Frame. You can use a frame from an old motorcycle or scooter, if there is none, then you can weld it to order. The turner can easily cope with such a task.
- Engine. You can use a motor from a walk-behind tractor, although it is worth saying that with its power, the resulting product is better called a children's snowmobile, it will not work to disperse it to a decent speed. There is an alternative to using a motor from a motorcycle or scooter. The choice of engine also depends on the weight of the snowmobile.
- Caterpillars. The most important and at the same time complex detail of a snowmobile.
- Drive unit. Connects engine and track. A chain from a motorcycle is great for driving.
- Steering wheel. Here you need to build on personal preferences and convenience, but most often it is also taken from a scooter or motorcycle.
- Skis. Here, a ready-made version is used, if any, or you can make skis from plywood. It is better to give preference to sheets of plywood with a thickness of at least 3 mm.
- Fuel tank. For this part, you should choose a container made of plastic or metal. The capacity of 15 liters is enough to cover long distances without taking up much space.
- Seat. It is best to make to order, since a homemade snowmobile will be operated in harsh conditions, strong, wear-resistant materials should be preferred. Do not forget about convenience, you should feel comfortable on it.
Can you make caterpillars yourself?
This is the most difficult element for self-manufacturing. The tracks of the machine play a decisive role in how fast the machine will reach, and what will be the hitch with ice. Qualitatively made in a handicraft way, caterpillars can last quite a long time. Most often, tires from a car are used for tracks. First you need to free the tires from the sides, leaving only a flexible track. Now you need to make lugs. To do this, use a plastic pipe with a diameter of 4 cm. It must be cut into pieces 50 cm long, the resulting blanks should be sawn further along. These parts are bolted to the tire. It is important to observe the same interval of attachment of the lugs, otherwise the track will jump off the roller. It will be optimal to mount them at a distance of 5 cm from each other.
Caterpillars are made in a similar way. For their manufacture, you need to use a conveyor belt, which should be cut off, making the length optimal for a home-made unit. It is important to correctly and securely hook the cut tape. To do this, its ends overlap each other by 5 cm and are fixed with bolts.
Alternatively, V-belts can be used to make tracks. They are fastened with lugs, forming a caterpillar with ready-made recesses for the gear.
When making caterpillars with your own hands, you need to take into account such a nuance: the larger the area of \u200b\u200bthe caterpillar, the better the device will pass through snowdrifts, but it will be worse in control. In stores, finished products are most often presented in three versions, with standard tracks, wide tracks and extra wide tracks.
To simplify your task, instead of self-production, you can purchase caterpillars in a store. Thus, you will get the opportunity to purchase tracks suitable for the terrain and travel conditions.
Assembly features
The finished frame, welded by hand or borrowed from other equipment, must be equipped with a steering wheel by welding. The engine is installed strictly in accordance with the drawing. It is best that it be located as close to the carburetor as possible. On the finished structure, you need to install tracks that were made in advance.
When the main work has been done, you can start connecting the tank, gas and brake cables, and installing the seat.
The easiest way to make a snowmobile
Taking a walk-behind tractor as a basis and modifying it into a snowmobile is probably the easiest way to create a unit for moving through the snow. It can be used completely, you can take only some details.
If the walk-behind tractor is used completely, then a frame with rear axle and modify the working shaft into a drive, which must transmit rotational movements from the engine to the caterpillar.
If the walk-behind tractor is not fully used, then only the engine and steering fork should be taken from it. Tracks will need to be installed on the bottom of the fork.
In this case, you must also take into account that the power of the walk-behind tractor is designed for the weight and pressure of the wheels, which are less than the tracks. In order to avoid unnecessary waste of gasoline and depreciation of parts, snowmobile tires should be low pressure.
Mini homemade snowmobile is easy to drive. By the way, if a home-made snowmobile turned out to be not very powerful and speeds up to 15 km / h, then it is not necessary to equip it with brakes. To stop a homemade snowmobile, simply reduce the speed, and it will stop itself.
Having approached the work seriously and having studied all the available information, you will surely be proud of your own assembled unit!
As soon as winter begins in our country, given the climate, two-wheeler removed to the garage until spring. It may be impossible to use the car for transportation due to heavy snow. And here, to the aid of all motorists who want to move along a snowy road, comes a snowmobile on tracks, which can be made from a walk-behind tractor with your own hands.
Not everyone has the opportunity to buy an additional vehicle for themselves, but everyone can independently design a home-made caterpillar snowmobile from a walk-behind tractor.
Advantages and features of a homemade snowmobile
- The vehicle has a mechanical drive and a caterpillar walk-behind tractor, when driving on which, you will not get stuck in snowdrifts.
- Management is due to skis, and steering system is in front, so you can easily control it.
- The price when buying a vehicle is important. Therefore, if you calculate, the cost of manufacturing a snowmobile on your own will be five times lower than buying it from a manufacturer. And even cheaper, it will come out due to the available walk-behind tractor and other parts.
- Reliability - where a person will not pass and a car will not pass, a snowmobile will overcome all obstacles with ease.
- If the snowmobile is made by hand, then the designer approaches the choice of parts very carefully. By doing everything yourself, you are responsible for the quality of your design. In addition, paying great attention to the nodes of the mechanism, you make the snowmobile all-terrain.
The device of a homemade motor-block snowmobile
This is a sought-after invention that you can do yourself with quality parts. The walk-behind tractor is taken partially (individual parts) or used completely. If you decide to use it not in a complete set, it is necessary to weld on it supporting frame with rear axle, steering fork and wheels. The most difficult stage in this case is the transformation of the working shaft of the walk-behind tractor into a drive gear.
The most practical and versatile solution in the manufacture of self-propelled guns will be the use of parts from a walk-behind tractor. You only need to remove the steering fork and engine from the finished walk-behind tractor.
The motor can be located at the rear of the structure.
Before starting the self-production of the structure, draw a drawing, assemble the entire necessary material, prepare the tool, and you can proceed. The design is quite simple and anyone can handle it, technical education and some skills are not required for this.
If you did not graduate from the Faculty of Engineering and it is difficult for you to draw up a drawing, use ours.
Drawing a simple frame for a homemade snowmobile
The drawing shows the frame that you will need in the manufacture of the snowmobile.
Motoblock in a homemade tracked snowmobile- this is the main part due to which your transport will move.
If everything is done correctly according to the drawing, you will have a goose-based snowmobile.
Snowmobile frame drawing on tracks
Making a caterpillar snowmobile with your own hands
Before starting work, decide on the tool. You can say with 100% certainty what you need: various screwdrivers, a hammer, welding, a pipe bender (if there is no finished frame).
Before preparing a drawing for self-manufacturing a snowmobile, familiarize yourself with the standard configuration.
- Frame. Each snowmobile has a frame: the more complex the design, the more reliable and strong the frame must be. The best option- take from an ATV, scooter or motorcycle. If there is no such part, you can weld it yourself from pipes with a diameter of at least 40 mm.
- Seat. The seat on the snowmobile must be strong, as the structure itself is quite low.
Mandatory condition: the seat must be made of waterproof material.
- Engine. When choosing an engine, pay attention to its power. If you want a powerful snowmobile, then the engine should be like that.
- Tank. A container with a volume of 10-15 liters, made of metal, is perfect for a fuel tank.
- Skis. If you do not have ready-made skis that can be adapted for a snowmobile, you can make your own from wood. It is better if it is plywood of at least nine layers.
- Steering wheel. When choosing a steering wheel, think about your comfort. It is best if it is borrowed from a two-wheeled unit.
- Caterpillars. Making tracks is perhaps the most difficult part in the whole self-propelled.
- Drive unit. In order for the tracks to rotate, you will need a drive - it is best to use a chain from a motorcycle in this case.
Frame
If there is no finished frame available, then it is easy to weld it from a profile pipe, and give it a shape using a pipe bender.
If it is not possible to make calculations and draw up a drawing on your own, then for example, use the drawing from our website.
Once the frame is assembled, treat it with an anti-corrosion compound and cover it with a quality paint that will withstand both moisture and frost.
caterpillars
Everyone who previously independently designed a caterpillar walk-behind tractor notes: making caterpillars is the most difficult process in homemade work.
The easiest way to construct them is from tires from a car. This option is the most advantageous - high-quality and low-budget. The part is made in a closed circle, so tire break cannot occur.
Caterpillars for a snowmobile from a tire (tire)
Instructions for making caterpillars:
- From a car tire: take a tire and cut off the sides (it is better to do this with a sharp knife). You need to cut so that the flexible part with the tread remains.
During cold weather, transport on two wheels becomes irrelevant, and it is sometimes impossible to drive in the snowy expanses even by car. What to do in a situation if there is no money to buy transport more adapted to the harsh winter?
In this case, you can make a homemade snowmobile. Winter vehicles are most often equipped with caterpillar drive, steering skis are installed in front. The snowmobile has high cross-country ability, light weight (70-80 kg), which allows it to drive both on valuable snow and on rolled snow. snowy roads. It is easy to drive this vehicle, and the developed speed is low. So riding a snowmobile in the countryside in winter is not only convenient, but also safe.
Features of homemade snowmobiles
A huge number of companies are engaged in the sale of snowmobiles in the CIS. But their prices are high even for families with decent incomes. If you don't want to pay extra money for advertising and are a hardworking and creative person, then try making a homemade snowmobile.
A self-made self-propelled gun costs 7-10 times cheaper than the cheapest factory-made models.
The success of your own snowmobile production depends on several factors:
- your personal skill;
- your engineering and design thinking;
- the presence of parts and assemblies from other snowmobiles, motorcycles and other things.
It should be borne in mind that riding a snowmobile, like any other vehicle associated with increased risk. Despite the fact that homemade devices, as a rule, are not able to reach speeds of more than 15 km / h, the quality of parts, welding, bolting of elements should be approached with all seriousness. The issue of operational safety and reliability of the final unit should be the main one for any person who intends to build a snowmobile with his own hands.
Training
Before proceeding with the manufacture of a snowmobile, it is necessary to calculate the main parameters of the apparatus. If you are a bit of a design engineer, then it is appropriate to make a drawing of the unit. In principle, all snowmobiles are arranged in the same way and simply. Your task is to make a reliable device in the model and likeness of all other variants of this class of vehicle.
What is required for manufacturing:
- Pipe for the frame, for pendants and other frame elements.
Experimentally, it was found that the optimal pipe diameter is 40 mm. If you are using a profile, then 25 x 25 mm will suffice. Wall thickness - 2 mm. With smaller parameters, the resistance of the device to deformations will be reduced. For large ones, the car will become heavier, which, accordingly, will affect the already not brilliant driving characteristics.
- Wheels with rubber on the axle.
Wheels from ATVs (small models with a wheel diameter of 30-40 cm), some carts, etc. will do. In total, 2 axles with 2 wheels on each are required.
- V-belts or conveyor belt.
The main element of the "caterpillars". The optimal thickness is 3 mm. This is enough for stability and wear resistance.
- PVC pipes.
Of these, lugs are made - the second element of the "caterpillars". The optimal diameter is 40 mm with a wall thickness of 5 mm.
- Propulsion system.
As a rule, use the engine, carburetor, fuel tank from a motorcycle.
- transmission mechanism.
As a rule, they use stars and a chain from a motorcycle, stars from snowmobiles. Drive shaft from any unit, suitable in size.
- Guide skis.
It is optimal to take skis from another snowmobile. Since this element should be as reliable as possible, designed for the load of the unit itself, plus the driver and possible passengers.
- Steering wheel.
As a rule, they use a steering wheel from a motorcycle, respectively, with a throttle handle and a cable.
- Platform, seat, body.
In principle, you can do without a platform by attaching the seat(s) and the body (optional) directly to the frame. But sometimes an additional platform is constructed on the frame, for example, from wooden boards, which provide slight depreciation, allow you to place several seats, and at the same time slightly burden the structure.
- shock absorbers.
This element adds additional complexity to the design. Therefore, they often do without it, especially if it is supposed to drive on unpacked snow. Depreciation is installed on the front suspension and the driver's seat. You can take from an old snowmobile or from a motorcycle.
- Small parts.
In addition to those listed above, other standard parts will be required to make a snowmobile: bolts, studs, nuts, hinges.
How to do: instruction
First, the frame is cooked - the frame. Obviously, the larger the frame, the heavier the apparatus will turn out and the slower it will move. Optimal length frames - 2 m plus / minus.
On the frame are sequentially fixed:
- drive shaft with a host star;
- power plant with a transmitting star and a gas tank;
- front wheel axle (fixed fastening to the frame by welding or bolts);
- rear wheel axle (fixed fixed with a movable guide element);
- front suspension with steering structure and guide ski(s);
- seat(s) and body.
Caterpillars are made from drive V-belts or a conveyor belt. The optimal width of the tracks is from 40 to 50 cm. With a smaller width (40), the snowmobile will be more maneuverable and better controlled. With a larger (50+) - the patency of the device improves.
The function of the lugs is performed by PVC pipes sawn in half along the diameter indicated above. They are attached to the rubber base with bolts and nuts. Insufficient width V-belts can be fastened together with metal grousers.
In order to be able to adjust the track tension, the rear wheel axle is mounted with a movable guide element, which allows the axle to be fixed in a certain position.
Additional notes:
- The center of gravity should be approximately at the center of the structure. Since the power plant is mounted in front, the driver's seat should be centered over the front axle or slightly shifted to the rear.
- Distance between drive shaft and power plant should be minimal in order to minimize the loss of energy transmitted to the shaft.
- If you install a shock absorber under the seat, then the front seat support is fixed rigidly on the profile arc, and the rear seat rests on the shock absorber.
- If you are making a snowmobile with the expectation of a large load, then to remove some of the weight from the tracks, it is advisable to install an additional ski in the middle of the base (between the two tracks). This ski, 50-70 cm long, is attached directly to the frame. However, this design involves a more accurate preliminary calculation with subsequent alignment of the height of the "legs", which complicates the manufacture of the snowmobile.
- It is desirable to maintain a low pressure in snowmobile tires to avoid rapid wear of parts and high fuel consumption.
The considered version of the snowmobile is the simplest in design. With tools, a welding machine, it can be assembled in the garage without problems.
I made this snowmobile in just a couple of weekends in the garage in the country. Although its design at first glance looks very simple, nevertheless, in terms of flotation in deep loose or wet snow, it is not inferior to most industrial snowmobiles.
A few years ago, I built a snowmobile for my nine-year-old daughter with a homemade track made from conveyor belt and plastic water pipes for grouser. At first, I had doubts about the reliability of such a caterpillar and how plastic parts would behave in the cold. But during the two years winter operation There were no breakdowns and severe wear of the pipes. This inspired me to create a light snowmobile for myself with the same homemade track.
Knowing perfectly well that the smaller the mass of the snowmobile and the larger the bearing area of the tracks, the better its patency in loose and deep snow will be, I tried to make the design as light as possible.
The principle of operation of a snowmobile is very simple (Fig. 1). Four wheels are installed inside the caterpillar, which, when moving, roll along conveyor belt, on which the lugs are fixed. And the caterpillar drive from the motor is carried out by a chain through the driven shaft with special drive sprockets. I took them from the snowmobile Buran.
With an engine from a conventional walk-behind tractor with automatic clutch with a power of only 6 hp don't accelerate quickly. I was going to ride a snowmobile not on rolled paths, but on loose snow, so I abandoned the soft suspension of the caterpillar and skis to reduce the weight of the snowmobile and simplify the entire structure.
First I made a caterpillar. I cut a plastic water pipe with a diameter of 40 mm into blanks for lugs 470 mm long. Then he sawed each blank with a circular saw lengthwise into two equal parts.
Using the device shown in Fig. 2, with a circular saw on wood, cut along plastic pipes for grouser.
I attached the lugs to the conveyor belt with two furniture bolts with a diameter of 6 mm with a large semicircular hat. In the manufacture of the caterpillar, it is very important to maintain the same distance between the lugs, otherwise they will run into the teeth of the drive sprockets and the caterpillar will begin to slip and slide off the rollers.
For drilling holes in the conveyor belt for fixing bolts with a diameter of 6 mm, I made a jig. The holes in the tape were drilled with a wood drill with a special sharpening.
Using such a conductor, 6 holes can be drilled in the conveyor belt at once for attaching three caterpillar lugs.
In the store, I bought four inflatable rubber wheels from a garden cart, two drive sprockets from a Buran snowmobile, and two sealed bearings No. 205 for the caterpillar drive shaft.
I asked a turner to make a caterpillar drive shaft and bearing supports. I made the frame of the snowmobile myself from square pipes 25x25 mm.
Since the hinge axes of the skis and the rudder are on the same line and in the same plane, you can use a continuous tie rod without ball joints.
Ski turn bushings are easy to make. I welded 3/4" female plumbing couplers to the front cross member of the frame. He screwed pipes with an external thread into them, to which he attached the bipods of the steering rack of the skis by welding.
I recommend using skis from the Argomak children's snow scooter. They are lighter and more flexible, but they need to be equipped with corners for attaching to the snowmobile's turntable and a metal undercut from the bottom - for better control of the snowmobile when driving on crust or packed snow.
The chain tension is adjusted by shifting the motor.
Driving a snowmobile is very easy. When the engine speed is increased by the handlebar throttle, the automatic centrifugal clutch is engaged and the snowmobile starts moving. Since the estimated speed of the snowmobile is low (only about 10-15 km / h) and depends on the density of the snow, the snowmobile is not equipped with brakes. It is enough to reduce the engine speed and the snowmobile stops.
I will share a few tips that may be useful when repeating this design.
1. I cut the pipe for the tracks along the manual circular saw on the tree, first on one side, then on the other. So it turns out smoother than cutting both walls at once. It is more convenient to process small workpieces. If you immediately cut along a long pipe, then in this case the plastic will melt and the saw blade will clamp.
2. Caterpillars can be made in any width. And each designer has the right to choose what is more convenient for him: to make a wide but short caterpillar or a narrow and long one. Just remember that with a large track, the snowmobile will be poorly controlled and the engine will be loaded more, and with a small one in loose deep snow, it may fall through.
3. In some of my photos you can see that plastic “barrels” are installed inside the caterpillar. These are guide stops for slip, which should prevent the caterpillar from sliding off the rollers. But during the operation of the snowmobile, the caterpillar did not slip off the rollers even without slip, so the “barrels” can not be installed, which will reduce the weight of the snowmobile.
4. At the end of winter, I completely dismantled the snowmobile to determine its weight. The weight of its individual nodes turned out to be as follows: caterpillar - 9 kg;
drive shaft assembly - 7 kg; two pairs of wheels with axles - 9 kg; engine and steering wheel - 25 kg;
a pair of skis - 5 kg;
frame -15 kg;
double seat with uprights - 6 kg.
Total all together weighs 76 kg.
The weight of some parts can be further reduced. Still, the weight for a snowmobile with a track of this size is quite satisfactory.
The geometric dimensions of my snowmobile are as follows: the length of the snowmobile frame is 2 m; distance between the axes of the support wheels (rollers) - 107 cm; track width - 47 cm. The step of the caterpillar lugs depends on the thickness of the conveyor belt and it must be selected empirically (I got 93 mm).
I don’t give the exact dimensions and drawings of the parts of the snowmobile, since everyone who is going to repeat the design will be guided by those parts and components that they can purchase or make on their own.
In remote areas where it is necessary to overcome considerable distances, fishermen and hunters need to have their own transport. Due to the high price today, many cannot purchase it and are trying to design a homemade snowmobile with their own hands. It is not easy to build it, but if you apply maximum patience and diligence, then this problem will not be difficult to cope with.
Frame construction
Before you start building a snowmobile, you first need to select the material. Easiest homemade frame make from wooden blocks. It will turn out to be a very light and fairly durable design, which is considered the cheapest and easiest to manufacture. For this you will need:
- Wooden bars.
- Sheet iron.
- Metal scissors.
- Drill and drills.
- Hand saw.
- Bolts and nuts.
The advantages of building such a structure are undeniable. In case of breakage, the wooden model will be easy to repair away from locality. In the forest, it is easy to find improvised material that can be used for repairs. But the main advantage is that this snowmobile rarely falls through the ice and does not sink in the water.
Wooden structure
It is known that bars and boards made of wood do not have special strength in their places.
connections. Therefore, before starting construction, it is necessary to make additional metal corners. To do this, take sheet iron and cut out square plates with scissors along the width of the bars. Places for bolts are marked in them with a tape measure, and then four holes are drilled with a drill. After that, the plates are bent in half strictly at 90 degrees. These will be excellent fixtures for firmly fastening wooden bars in the corners of a homemade frame.
Usually they start construction after they make a drawing with exact dimensions. And already four bars are cut off with a hacksaw, and holes for bolts are drilled in the corners with a drill. Then they are placed on a flat floor surface in the form of a regular rectangle. Metal corners are applied to the joints, bolts are inserted and tightly tightened with nuts.
To mount the engine and caterpillars on the frame, an additional two more crossbars from bars with bolt holes at the ends are installed. But before that, corners for fastening are first made. They are cut out of triangular iron sheets and drill holes in the corners..
It is better to immediately make eight pieces and put them on top and bottom. Then the fasteners will be more durable and reliable in operation.
When they are ready, crossbars are inserted inside the frame and triangles are placed on top. In them, holes are drilled exactly in size with a drill through the bars. Then long bolts are inserted there and tightened tightly with nuts. On this, a solid wooden frame will be ready, which will last a long time on a homemade device.
It is much more difficult to engage in the construction of homemade metal products. It requires special tools and devices that not everyone may have. Significant costs will be required to purchase or rent them. However, this building will be much stronger and more durable than a wooden structure.. Here you will need:
In addition, more durable materials will be needed to build a metal frame. You will definitely have to buy them in the store, since today they are not found anywhere else. And I don’t really want to build a new home-made snowmobile from old parts because of poor reliability. Therefore, only good materials will be used here:
- Metal pipes.
- Iron corner.
- Sheet steel.
- Channel.
As a rule, before starting the construction of the frame, you need to make a simple drawing. According to its parameters, cut the pipes with a grinder and use a welding machine to connect them into a rectangle. Inside the frame, insert a couple more partitions from the corner for installing the engine and caterpillar. If you make them from a channel, then the design will be much stronger and more reliable in operation.
After that, you just need to cut off two small bushings from the metal pipe.
And then weld them to the corners of the front, where the swivel ski supports will be inserted. The metal frame is ready and you can start building, as well as installing the main units and assemblies.
Hanging equipment
To make a snowmobile fast and strong, you need to put on the frame good engine. If you install a low-power motor, then this design will move poorly. And also you need to correctly calculate the caterpillar. If the area is too small, it will sink in large snow and will not pull even on flat terrain. Particular attention should be paid to skis, which should create good stability and safety when driving at high speed.
DIY rubber caterpillar
In order to move easily in the snow, it is very important to make a good rubber track for a homemade snowmobile. It is not easy to make such a device with your own hands and it is better to purchase it in a store completely with rollers. Installing a standard factory track on a homemade structure is not difficult. To do this, you only have to fix the drive shaft and rollers with bearings on the frame. If the financial situation does not allow you to buy the entire device, then the most expensive parts are easy to make yourself. This will require:
- Conveyer belt.
- Plastic pipe.
- Bolts, washers and nuts.
cheap homemade caterpillar for a snowmobile, they are usually made using a thin conveyor belt. To do this, blanks from a plastic pipe are sawn off along the width of the rollers. Then they are cut lengthwise into two equal parts and holes are drilled for small bolts. After that, the halves of the plastic pipes are fixed on the conveyor belt with bolts, washers and nuts. The caterpillar is ready and you need to proceed with further construction.
Homemade skis
It is no secret that in winter it is much more convenient to ski in deep snow. They also serve well as a control device on a snowmobile. It is not difficult to make a wooden structure, but only durable boards made of birch or oak are suitable for this. They must be well dried, planed, and then heated and bent the ends. It's not harder to make metal skis. To do this, you will need to cut two plates from sheet steel and weld a thin corner on the sides.
In order for the skis to turn freely, metal pipe racks are welded to them. In working condition, they are held in the front bushings of the frame, where they rotate easily..
Washers or large nuts are welded to the top of the racks, where the rods are inserted to control the snowmobile.
The steering wheel itself is easy to do with your own hands or it is easier to remove it from an old motorcycle. Thus, it remains only to install the motor, as well as the driver's seat, and you can move on.
