“Ancestor” of this machine, lawn mower GK-1 was built by students in St Michael’s training and production plant in 1978. About it has told the head of young technicians — lecturer of the criminal procedure code V. I. Popov (see “M-K” № 6, 1981). However, the possibility that the mower was still insufficient: the width was only 1 m and the actuator will bind the mechanism to a power source and thereby limiting its autonomy. This was the reason for making a new variant with high performance. The novelty was successful. Among the exhibits of the III all-Russian rally labor unions of students in urban schools, held in Rostov-on-don, she invariably attracted attention and was awarded by our magazine (see “M-K” N° 1, 1985). By the way, after this publication in the code of criminal procedure, Michael began to come from all over the country a letter asking them to send drawings of the mower. To answer each individually the authors, of course, was not. Today we provide the pages of the magazine mentor young designers of this machine.

On the mechanisms used to its movement due to inertia of the rotating imbalances of the journal “modelist-Konstruktor” wrote more than once (see number 5 and 12 for 1975, No. 6 1976, No. 3, 1978). The publication aroused great interest among readers, so we return to this topic. The amazing ability of nutricola, or inertsioidov, as they are called — to move without using wheels, tracks or air screw — continues to captivate enthusiasts-inventors. And although the effectiveness of this type of propulsion is not yet well-known competitor, perhaps one of the most perfect models of nutriton will be a prototype of the future transport. And while we offer to your attention another scheme inertsioidov mover. Its author — kas reader from the city of Ryazan Alexander Mikhailov.
Nice in the summer, sitting comfortably on a bench, in a chair, read a book, chat with friends. To protect the resting place from the sun, we offer you to build beautiful and easy “umbrella”: a graceful gazebo.
On private land, perhaps only a decorative grass — raygrass — tracking, scattering the seeds. The vast majority of annual flowers and vegetables planted in rows: so the plants are easier to handle and feed. But since seeds are small, often the shoots are too dense. You have to spend a lot of time pulling, away, by the way, is harmless to the root system.
Manual digger “spider” is a good help in the garden at harvest of potato, transplanting of seedlings and even during the digging of ditches. He sharply — and a half-two times — increases productivity because it captures the ground with one hand, like a shovel, but with two, and easily frees up the tubers from the ground and brings them to the surface.
He was 90 years old. For many, this is not only creative, but also a physical limit. But Alexander was embarrassed when it came to the car to take to the editorial Board for a meeting dedicated to his birthday: “Why worry? I would perfectly got on the subway!” Others in his years of talking about health and medications, and Alexander eve was called to talk about his new model of the original engine. Their A. S. Abramov and known to our readers.
More widely used today snowmobile technology. Industry and Amateur craftsmen create a wide variety of vehicles specially designed for use in the winter. For now the spring comes, and the powerful “Buran” is sent to the Parking lot to the garage to wait for the next season, and its owner is transplanted to the other “horse”, most often the motorcycle. But would it be useful to have two almost identical vehicles differing only in chassis? Can we make a universal motorcycle-snowmobile? This task is successfully solved by our readers from the city of Votkinsk Udmurt ASSR A. Drummers.
The concrete wells are strong and durable. They are relatively simple to manufacture, is relatively easy and their installation.
Now more and more can be found on the streets guys, balancing on the rolling boards. They are not only confident of their own on descents: even the most adept going up a hill, easily doing complicated pirouettes ka slalom tracks, sometimes demonstrate a downright acrobatic stunts. Popular among young people, the shell is called a skateboard, occupation — rolling. Movement standing on a roller Board are very similar to those performed by the skier passing through the gates on the descent, or the surfer, especially when you tack. Indeed, the skateboard was created as a simulator for the skier, but soon became widespread as an independent apparatus. Rolling becomes a sport: many fans began to unite in section at stadiums, various sports clubs. According to the head of laboratory all-Union scientific research Institute of physical culture, doctor of medical Sciences V. V. Matte, skateboarding develops agility, reaction speed, coordination of movements.
Originally solved the problem of production of the fairing for racing córdoba in the box O. UFOs from the city of Ilyichevsk of Odessa region. He refused a long and laborious work with wood and uses ready-made parts — housing from industrial plastic kits. copies of the aircraft. It is only necessary to reinforce the thin-walled shell in intense areas with fiberglass and epoxy resin, and cut the lower part of the fuselage. Best suited case from a large transport aircraft, the keel is either not trimmed or shortened.
