Russian people are immodest in dreams and extremely inventive. We, unlike the Americans, have more tools to fix the vacuum cleaner. In addition to super glue and adhesive tape, we have at least a hammer and a pair of screwdrivers. We have more than enough masters. And the shock absorbers from the “penny” are put on Japanese subcompacts, and the gas pump from the “nine”, as a native, is put on the BMW “C grade”. Only need to grind, solder, etc. etc. The desire for homemade products is almost in our blood. It is difficult to meet a person who at least once in his life did not try to make something. And not only in childhood! There are many lovers who make their whole life and at the same time get the same pleasure as in childhood.
Today, the topic of self-made wonders of technology will be continued by the following question: “How to make a snowmobile with your own hands?”. A homemade snowmobile is not a spaceship. It’s not easy to assemble, but possible. Consider the first option.
We need an old moped (a new one will also work), scrap metal and a welding machine. The last two points are needed, first of all, to create a frame, since only a steering wheel, fork, tank engine with its frame will remain from the moped.
We start homemade. Snowmobiles, as you know, are not available with the wheel in front. We remove it and forget about its presence, now we remake the design of the fork for mounting the ski. By the way, it’s better to buy skis that the front and the rear are in the store. You will have to make your own from duralumin, which is cooked only with argon. Not everyone has an argon welding machine. Having remade the moped in front of the winter version, we go to the rear. Our homemade snowmobile will move forward with the help of a wheel, or rather a drum with a welded “tread” to which a chain connected to the engine is attached. For structural stability, you need to create a trapezoid frame.
Above the seat, under the seat there is a “wheel”, on the sides of which there are skis. Please note that the lugs on the drive wheel should be small. In the event of an obstacle due to excessive load, the circuit may break. It is better to do a muffler yourself, special skills are not needed. A homemade snowmobile will attract attention anyway, so extra extra decibels of sound won't add much. It is worth clarifying that to transfer the trigger from the foot to the manual also does not hurt. It’s hard to get on the pedals in felt boots, but hands are another matter. It’s easy, it’s worth a try. After all, not everyone will decide to make DIY snowmobiles with their own hands.
Option Two. If somewhere in the village you have a motor-block idle, then you will have its engine, just in time. So, you have already found 6 horsepower. What to do with them? Just start home-made - snowmobiles will simplify winter weekdays in seconds.
To move around, you need a crawler engine. Finished parts from the caterpillar, for example, "Buran", will greatly simplify the process. On specialized sites dedicated to the topic "do-it-yourself snowmobile", you can easily cheaply buy a special installation motorcycle kit that will turn any motorcycle into a snowmobile. The kit includes a caterpillar engine with a pair of tracks and a replaceable ski in place of the front wheel. Since the track support area does not exceed 120 kg, this is a great option for a portable snowmobile. Now it remains to install a motoblock engine, a folding front part and a seat on it. For greater stability, it makes sense to install two skis in front instead of one.
The collapsible frame is made of pipes 25 * 25 and 50 * 50 mm, the seat - from a small scooter, the steering wheel - from a bicycle. For the convenience of transportation, it will be more convenient to install a 20 kg engine with a clutch on a quick-detachable platform. A homemade snowmobile can get swivel racks thanks to the frame pipes and wheel forks from old bicycles.
