Winter exotics: we understand unusual types of snowmobiles

DIY mini snowmobile

Dear visitors to the “ Samodelkin Friend ” website, from the material presented you will learn how to independently assemble a snowmobile with an engine from a walk-behind tractor.
Step-by-step assembly photos and a video of the mini-snowmobile running in are provided. Every avid fisherman and hunter knows perfectly well that in winter it is not very convenient to travel on loose snow on skis, and when it is necessary to cover a distance of several tens of kilometers to a farmstead, winter hut, hunting hut, or to a reservoir, then there is generally a “pipe)) For To cover long distances you need a snowmobile, but the prices of factory-made cars are beyond the means of the common man; again, repairs and spare parts will cost a pretty penny. So we do it ourselves, with our own hands)) To build the snowmobile, the author used an engine from a Lifan walk-behind tractor with a power of 9 l/s, this type of engine is very popular today among home-made people, wherever they are installed) tractors, all-terrain vehicles, boats, etc. The internal combustion engine is located in the rear of the car directly above the track; by the way, it is made from half of the BURAN caterpillar cut in half.

The snowmobile runs quickly through the loose snow, carrying two people and runners with luggage, which once again proves that Kulibin’s business is alive and growing)

Materials

1. ICE “Lifan” 9 l/s
2. professional pipe "square"
3. caterpillar "Buran"
4. chain
5. star
6. bolts, nuts, etc.

Tools

1. welding inverter

Assembling a snowmobile with your own hands.

This snowmobile is very compact and at the same time quickly assembles and disassembles, literally in 5 minutes. It also easily fits disassembled into the luggage compartment of a car.

The caterpillar is made from BURANovskaya caterpillar cut in half; aluminum tracks made from profiles are additionally installed.

Here's a snowmobile)

Snowmobile Rybak 2-MR

Rybak 2MR is a collapsible two-seater mini-snowmobile of the motor-transformer type, designed for movement on loose and deep snow. The equipment is equipped with a four-stroke internal combustion engine, an automatic clutch, a trunk, a front bumper-seal and a reinforced towbar, which allows you to use the snowmobile as a motorized dog (motorized towing vehicle) in difficult terrain. Reviews from mini snowmobile owners characterize the Rybak 2 MR as a snowmobile for lovers of winter fishing and hunting due to its low pressure on the snow and its efficiency.

Do-it-yourself motor sleigh for winter fishing

As soon as winter comes with snowfalls, movement on the roads becomes difficult. In order to be able to move freely in snowy areas, it is absolutely possible to assemble a full-fledged snowmobile from improvised means.

At the same time, you don’t need to spend a lot on a new vehicle. The benefit of this is especially visible when a car does not allow you to move in snowy winter conditions, and even when the roads are not cleared. In this case, the benefits of a snowmobile in a snowy winter are, as they say, obvious.

Any design should begin to be assembled by first developing drawings. All the necessary parts and components are indicated on them, after which the stage of practical implementation of the idea begins. In our case, first of all, we need to determine the brand of chainsaw that will be used in the construction of the snowmobile.

The design of our homemade vehicle is simple and practical. On a small sled made from pipes and angles, the engine and gearbox of the Druzhba chainsaw are installed. In order for the engine to operate stably, a carburetor taken from a Chinese moped was installed.

The chain drive runs in the direction “drive sprocket” – “driven sprocket (from a motorcycle)” of the wheel. The wheel before this was on a scooter; the tire was covered with spikes and hooks, for a confident ride on an icy surface. The wheel is mounted on levers - when the driver gets on the snowmobile, the wheel is pressed against the ice by levers. As a result, the wheel is pressed tightly against the ice surface.

The steering wheel was installed as usual, like on a bicycle. Only here it is not a wheel installed, but a guide (skates have a similar design).

The snowmobile is designed with a protective cover over the wheel, and with a lever brake made by the author of the homemade product.

The result is a very convenient vehicle that moves quickly on the ice - with it you will quickly find a fishing spot with a good bite.

Motorcycles for fishing with riding in the snow - description

It is often used by fishermen and hunters in winter to move long distances on ice. Traveling by car is not only unsafe, but in some cases it is impossible due to the lack of access to the entrance.

Motorcycles resemble in appearance a combination of sleighs and skis with a motor. They are available with both automatic transmissions and CVT, which is more convenient and cheaper.

Design Features

The features include the mandatory components of such a vehicle, without which it will be impossible to move properly:

• The motor is what sets the device in motion. If you make it yourself, an engine from a moped will be suitable, which will be resistant to frost;
• The gas tank is where the liquid is poured. You can use a gas tank purchased in a store or from scrap materials. You should absolutely not use plastic containers that cannot withstand fuel.
• Wheels and skis are what motorbikes use to move around. You can use absolutely any wheel, but a car wheel is best;
• Skis should be stronger, so it is recommended to take mountain skis;

Dimensions and weight

Sizes may vary depending on the model range. The average assembled size is 1500x750x600 mm, in working condition 2700x650x750 mm.

The weight of the product itself also depends on the brand and power, for example from 65 kilograms to 120. The weight that can be transported is 20-40 kilograms.

Movement speed

The maximum travel speed in the minimum configuration is 20 - 25 kilometers per hour, and in the maximum configuration 70 - 80 kilometers per hour.

Do-it-yourself motor sleigh

Many people living in cities and villages, where there is more snow than asphalt, are concerned about the question of what to get around on. The ideal option is a snowmobile. But not everyone can afford such a purchase. At such a moment, it is worth remembering what our fathers did in such a situation. And they made motor sleighs. Yes, you can buy them ready-made. But the problem is that not all cities have them on sale, since this is a new product on the market, and besides, homemade ones are always better. Therefore, if you have certain skills and experience, you should decide: “We make our own motor sleighs.”

Motor sleigh - what and with what

But first, it’s worth understanding what a motor sleigh is and what they are needed for. Motor sleighs are a means of transportation and cargo transportation in snowy conditions. They are basically a very small snowmobile with a wheel. The motor is used either from a scooter or a snowmobile.

For control, there is a handle on which the brake system and fuel supply lever are installed. The seat is small, designed for one person. It is driven by a small wheel with very spiky rubber or a small track. For comfortable movement on snow, skis are installed.

In general, making a snowmobile yourself is not as complicated a process as it might seem at first. Homemade products only seem complicated at first. It is enough to have basic knowledge of how motors work and learn (or ask someone) welding.

Where to buy motorfins, their cost

There are several ways to purchase a vehicle called a motor vehicle:

1. In a large store dedicated to active sports and fishing. The positive aspects of this choice will be the model range, which can be inspected and tested.
2. Order in the online store with home delivery, check can also be done by courier. Only here payment must be either upon receipt or with an initial payment, which should be trusted only to trusted companies;
3. At the wholesale base, where the price will be slightly lower than in the above centers. The seller will help you make a choice and tell you the positive and negative sides.

What you need to know about the design

• A motor sleigh consists of a running gear - a motor, a gas tank, wheels, skis, a fuel supply and ignition system. Control - steering wheel, much like a bicycle. There is also a frame and a seat. Let's take a closer look at each element of the chassis.
• Engine – for making a snowmobile with your own hands, a small engine from a scooter or moped is ideal. It is important that it withstands cold weather well and has the ability to be wound by lever or cable. It was also possible to use the oil-fuel mixture as fuel.
• Gas tank - any container that can withstand the presence of fuel inside will do. Therefore, plastic bottles are canceled - they can melt through. An excellent option would be to use a ready-made gas tank. But if you are itching to make a sled with your own hands inside and out, then you can make the tank yourself. This will be discussed later.
• Almost any wheel will do, but it is best to use a car wheel, as it is easier to find studded tires for it. An excellent option would be a wheel from an enduro motorcycle; even a porcupine might envy its needles.
• Skis – it’s better not to skimp here and use alpine skis. They are stronger and more flexible, so they can bear weight more easily. If they don't fit in length, we make them shorter.
• Fuel supply and ignition - everything will be together with the assembled engine, so there is no need to invent anything here.

Well, as for the rest of the elements, it’s already clear; we come up with everything ourselves and make it for ourselves.

It is also worth paying attention to motor sleighs with caterpillar tracks. Yes, this look is more difficult to do yourself. But at the same time, the motor sleigh will feel much better on ice and crust.

Famous models and brands

There are several developments, both domestic and foreign, that are widely popular. After all, mini-snowmobiles are in demand not only in the domestic market, but also in European countries. The most popular models include:

Domestic fishermen speak well of domestic developments such as “Burlak” and “Razgulay”. These models are lightweight and small in size, and when disassembled they can be stored in an ordinary apartment. The vehicle is assembled in a short period of time. Despite the presence of two anglers with equipment, it can reach speeds of up to 20 km/h.

Mini-snowmobiles " Vyuga " are distinguished by the presence of all the necessary data for movement on snow. The method of controlling the device is quite simple, which is accessible even to a beginner. Thanks to the presence of comfortable and powerful skis, the snowmobile can move through deep snow or off-road without any problems.

The “ Husky ” model is characterized by fairly small dimensions, so it can even fit on a balcony, naturally when disassembled. The product is assembled or disassembled within 2-3 minutes.

The “ Tourist ” design has a very simple control system. Therefore, even a teenager can master the control of this model. The development is lightweight and compact, as well as fuel-efficient. This unit starts in any conditions and in any frost. A fairly successful design that is in wide demand.

When choosing one of the snowmobile designs for yourself, you should pay attention to reliability, build quality and safety. How to do it? Yes, very simple! You should always opt for well-known models that already have their own buyer and a lot of positive reviews.

It is very important that the model consumes little fuel. Nowadays, saving comes first.

What can you take ready-made?

To make something like a motorbike, you don’t need to do everything from scratch. You can take some element, design, sold in the store. In order not to buy a new scooter, you can take it from your own hands, it will be even cheaper. An even cheaper option is to look at the disassembly markets, where there is a lot of this extra stuff. You can use a snow scooter for the base of a motorized sled, but you need to choose a completely metal one and additionally change the design with your own hands, otherwise this subtype of sled simply will not withstand the loads.

Hanging equipment

To make a snowmobile fast and strong, you need to put a good engine on the frame. If you install a low-power motor, then such a structure will move poorly. You also need to correctly calculate the caterpillar. If the area is too small, it will drown 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 moving at high speed.

DIY rubber caterpillar

To easily move through the snow, it is very important to give your homemade snowmobile a good rubber track. 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 just have to secure the drive shaft and rollers with bearings to the frame. If your financial situation does not allow you to buy the entire device, then the most expensive parts can be easily made yourself. For this you will need:

1. Conveyer belt.
2. Plastic pipe.
3. Bolts, washers and nuts.

A cheap homemade snowmobile track is usually made using a thin conveyor belt. To do this, plastic pipe blanks are sawed off to fit the width of the rollers. Then they are cut lengthwise into two equal parts and holes are drilled for small bolts. After this, the halves of the plastic pipes are secured to the conveyor belt with bolts, washers and nuts. The caterpillar is ready and further construction needs to begin .

We assemble the sleigh with our own hands

First, you need to decide on the design; to do this, look for photos or videos of motor sleighs and copy them. If you intend to make motorfins yourself, then you should arm yourself with a pencil. First, sketch out on paper what you want to see. After this, begin to sweep aside those parts without which the unit will not lose its qualities. Add stiffeners and fastenings as necessary. Once you finally understand what you want, move on to the drawings. At this stage, it will become clear which bolts and nuts are best to use, which elements will be homemade, as well as the main welding points.

Look for scooters at scrap yards or markets. Any will do, the main thing is that their engine volume is no more than 50 cubic centimeters (otherwise the sled will fall under the A1 license category). Also take into account such a nuance as a stable injection and ignition system. Remaking it yourself and bringing it to mind is for those who want to do absolutely everything with their own hands. A gas tank would be a good idea. But at the same time, you can use a can of gasoline, or make it yourself.

Important: do not solder the tank under any circumstances. Only welding. Otherwise, you can witness the “tin plague” - a process when tin becomes brittle in severe frost and breaks out of the seams.

Start assembling the frame following the drawings. At this stage, the ability to do your own welding will come in handy. Use pipes for the frame. They are easier to bend than rolled profiles. They can also be connected at sharp angles without loss of stability. This will make your sled more aesthetically pleasing. Don't forget to also make a bushing for the snowmobile's steering wheel. Simply weld a piece of pipe larger than the handlebar post at a 90-degree angle to the frame.

Start putting all the parts together, from the engine and cables to the pipes. It is worth considering that skis are best secured on a low-moving basis. After you have installed everything yourself on the future motor sled, do not be lazy and test them. As soon as the shortcomings are corrected, install the seat.

Tip: use non-flammable insulation, such as glass wool, as seat padding. Then it can be mounted on the cylinder block, having previously strengthened it - this way you will get a motor sleigh with a heated seat.

Frame construction

Before you begin building a snowmobile, you will first need to select a material. The easiest way is to make a homemade frame from wooden blocks. The result is a very light and fairly durable structure, which is considered the cheapest and easiest to manufacture. For this you will need:

1. Wooden bars.
2. Sheet iron.
3. Metal scissors.
4. Drill and drill bits.
5. Hand saw.
6. Bolts and nuts.

The advantages of building such a structure are undeniable. In the event of a breakdown, the wooden model will not be difficult to repair far from a populated area. In the forest it is easy to find scrap materials that can be used for repairs. But the main advantage is that this snowmobile rarely falls through the ice and does not sink in water.

Wooden structure

It is known that bars and boards made of wood do not have particular 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 square plates with scissors along the width of the bars. The places for the bolts are marked in them with a tape measure, and then four holes are drilled with a drill. After this, the plates are bent in half exactly 90 degrees. These will be excellent devices for firmly fastening wooden blocks in the corners of a homemade frame.

Usually they start construction after making a drawing with exact dimensions. And four bars are cut along them 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 connection points, bolts are inserted and tightened tightly with nuts.

To mount the engine and track, two additional crossbars made of bars with holes for bolts at the ends are installed on the frame. But before that, the corners for fastening are first made. They are cut out of triangular shaped iron sheets and holes are drilled in the corners .

It’s better to make eight pieces at once and place them on top and bottom. Then the fastenings will be more durable and reliable in operation.

When they are ready, the crossbars are inserted inside the frame and the triangles are placed on top. Holes are drilled into them exactly to size using a drill through the bars. Then long bolts are inserted there and tightened tightly with nuts. At this point, a strong wooden frame will be ready, which will serve for a long time on a homemade device.

Metal frame for snowmobile

It is much more difficult to build homemade metal products. This 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:

1. Welding machine.
2. Electrodes.
3. Mask.
4. Bulgarian.
5. Spanners.
6. Pliers.
7. Hammer.

In addition, to build a metal frame you will need more durable materials. 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 homemade snowmobile from old parts due to poor reliability. Therefore, only good materials will be used here:

1. Metal pipes.
2. Iron corner.
3. Sheet steel.
4. Channel.

As a rule, before you start building a frame, you need to make a simple drawing. Using a grinder, cut the pipes according to its parameters and use a welding machine to connect them into a rectangle. Inside the frame, insert a couple more partitions from the corner to install the engine and track. If you make them from channel bars, the structure will be much stronger and more reliable in operation.

After this, you just need to cut off two small bushings from the metal pipe.

And then weld them to the corners of the front part, where the swivel ski supports will be inserted. The metal frame is ready and you can begin construction, as well as installation of the main units and components.

How to choose an engine

In order to create a snowmobile, it is necessary to take into account the most important and central part of the entire mechanism - the motor. The motor must have decent traction in order to move the entire mechanism in difficult snowy weather conditions. For everything to work out as it should, a powerful motor from the Neva walk-behind tractor will do.

If such an engine is available, one or two people will be able to move on a homemade snowmobile from a walk-behind tractor with their own hands. The engine power is 6-7 horsepower, which is quite enough to move on snow cover.

If you add a snowmobile stand to the walk-behind tractor, the lifting force will increase and you can easily load your walk-behind tractor for snow trips.

What is good about this engine, many ask. In fact, there are many more advantages than you might think:

• First of all, it is an affordable price.
• Also good quality is proven by Japanese production.
• The motor has an additional air cooling system.

Also note that gasoline can be used as fuel.

Collapsible snowmobile designs

Most anglers prefer collapsible snowmobiles and believe that they are much more convenient and practical. In fact, if it is not a mini snowmobile, such designs differ only in minor features. Eg:

• The size and weight of the vehicle are significantly larger, so even when disassembled, its parts are unlikely to fit in the trunk of a car. Therefore, the transportation process is somewhat problematic.
• The movement speed reaches 70 km/h, thanks to a more powerful engine.
• Assembling such a structure is much more difficult, especially alone, since the structural elements have significant weight.
• Large dimensions allow several fishermen to move around on the vehicle without any problems.
• The carrying capacity of these structures is much greater than that of mini-snowmobiles.

Features of the design plan

The simplest version of a snowmobile consists of a part that drives and one that is driven first. The second part consists of a seat, shock absorbers, a steering part and runners, thanks to which this part moves. The second part is much more complicated, since it contains all the elements that set the snowmobile in motion.

First of all, in the second part it is necessary to correctly provide the power unit, that is, the motor itself. The frame on which everything will be arranged and the drive are also important.

Do-it-yourself diagrams and drawings of a snowmobile from a walk-behind tractor must be made in advance, and you can find the required option on the Internet or in various types of literature.

First, before drawing up the drawing, determine the purposes for which the snowmobile will be used. After the drawings, you will need to select the parts, and, if possible, make some with your own hands.

How to fish with an elastic band correctly

I’ll tell you straight that even the mention of such gear as an elastic band, like a donkey with a rubber shock absorber, makes me smile nervously and have some semblance of micro-tremors. An experienced psychologist who can read gestures would clearly say that I don’t really like this tackle. And this is the honest truth.
