Fifteen years subscribed to the magazine “modelist-Konstruktor” and in each room find a lot of interesting and useful articles. By education I am a mechanical engineer and I am particularly interested in creative development of designers-homebrew. I myself, back in 1989, almost from scrap (selected on the farm “technologisch” aggregates and agricultural machinery) has built a machine that for a set of functions called tractorable. Can not boast of originality of design or elegance of appearance. Rather, the tractor turned rough, but it for years I became an indispensable and reliable assistant on the farm in summer and winter. Wrong cut, but tightly sewn — this saying can be attributed to him.
Bicycle makers, both professionals and Amateurs, have long been trying these “broken” cars and more “tame”, that is, to use hands. But since a Bicycle hands are occupied keeping balance by finely balancing the wheel, then to implement it without deterioration of the stability (and, hence, traffic safety) is very difficult. Nevertheless, the idea promises in addition to the physical development of upper limbs and even a significant increase in non-motorised power car.
Not the first time the editors publish original contributions on the improvement of the Bicycle, the author of which is an inventor, engineer Vladimir Gavrilov from the village of Inozemtsevo area of Zheleznovodsk in Stavropol region. With his enthusiasm, he engages in technical creativity and other. An example of this— the second development in this publication, by V. Gavrilov together with his fellow villager M. Losev.
Conceiving the design of the moped, I set a goal to make it easy to operate for the driver any age. This moped I have and get: easy to control on the road and on the dirt road, with adjustable height of driver steering and saddle, stable and powerful at the expense of front-wheel drive with unpretentious D-6 engine. On the latter suffice it to say that it starts as a scooter with a push.
At the time of making this simple craft, even the name of which is hard to find: “whether the junk, or boat, or boat, or raft”, I had a “Kazanka” boat is roomy, durable. However, it was intended for sailing with an outboard motor. But what, say, fishing in a quiet backwater after it came a motor boat. To walk on the oars “Kazanka” too heavy and unwieldy. Shipping it to the waters too troublesome to do without the trailer and the assistant was not possible.
Agile, compact vehicle is vital, especially in the snowy and wooded areas. In some countries, for example, in the US, Canada, Japan, this problem is solved by the small-scale production of cars type motoart. Our industry has also begun to issue such equipment: there motonarty “Buran”, Amurets and others. However, these machines are more for entertainment, they have not even insulated the cab.
Gardener, gardeners, builders difficult to do without such a vehicle, like a car. When moving a wide variety of goods it greatly facilitates the hard work — saves energy, time, and possibly health when the volume of traffic is significant. In the markets of construction materials and are sold in hozmage cars of various designs. But at a price that is incomparable in their efficiency. Besides, they are made according to the type of commercial trucks with the wheel in front of the loading platform (or body).
At the time I had a chance to build and test many motor boats. The first water I came off the boat “star”, the drawings of which were published in the October issue of the journal “modelist-Konstruktor” for 1966. It is known that the village of homebrew not spoiled by the wide range of structural materials. What was required for the construction of the “Stars” for a long time was not. Had to make do with what was in the moment at hand, namely, a steel sheet with a thickness of 1.8 mm. Naturally, the power set of metal profiles and strips of different cross sections, coupled with sigouney paneling gave the boat a pretty solid mass.
I’m a longtime admirer of the magazine “modelist-Konstruktor”. In the publications of improvised technique find many useful, and most importantly — increased creativity and a desire to design your own technique. I also homebrew with the experience. In recent years, made three tillers for themselves and their relatives. For processing country of six acres, but still planted mostly fruit-berry cultures, these machines are very suitable. But if the plot is bigger, then their effectiveness is eroding. Without a tractor here not to do, even a small mini. Here I am, before you take a plot of land on the former state farm field is abandoned, decided to make and made a good assistant — a mini-tractor.
As you know, for different road conditions: descents, climbs — many types of bikes use a block of sprockets of different diameters for changing torque to the rear driving wheel. These mechanisms are relatively complicated, high cost structure, which does not allow to use the foot brake. But torque can be adjusted by changing the length of the connecting rod! And their mess is easy to exercise at home on all road bikes.
