“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.
Getting the design of this machine, I proceeded above all from the conditions of its future work. The soil in our area is mostly heavy loam, stones… and surface plots are far from perfectly smooth. In short, the operation was not easy. This fact determined the choice of the main parameters of the mechanism.
For simplicity, I decided to make the walk-behind, in-parzych, unicycle, and secondly, on the basis of units, components and parts of various machines manufactured in the factory. Took the frame of the motorcycle M-105. To do this, cut it up the pipe in four places: 60 mm higher than the front bracket of the engine mount 165 mm above the same rear bracket and 50 mm above the curved pipe going to the back of the pendulum fork (both sides).
In “M-K” was published, the drawings and description of electric spinning-wheel; material found a ready response among our readers. However, some believe that an electric spinning wheel to use is not everywhere and not always convenient, and therefore asked to talk about simple, non -—, “grandmother”. For Example, N. Konovalov from Transbaikalia wrote us; “In the village of Russian Samobranka a necessary thing, and the city will come in handy too. But the thing is that artists who could make this old tool with foot drive, virtually no.” We offer you to become the master, the drawings and description of a spinning wheel is given below.
Simplicity in manufacture and maintenance, reliability, versatility— these are the qualities that I wanted to achieve by producing tillers. Now, after two years of operation at the farm, I can say that the goal is achieved:
For many Amateur designers is one of the most challenging elements is the frame. On it are mounted the main aggregates, it determines the strength and dimensions of the future car. And to make the most simple and reliable — welded — not always possible. That’s why published in one of issues of “Panoramas “M-K” design of motor-plow assembled on the base frame from the bike, interested many of our readers. About your veloplugs created by podcast magazine, says our reader of the Kharkiv region, V. A. Zayets.
The editors have received many letters on the publication of “Biogas: and warms, and cooks” (see “M-K” № 1, 1987), based on the materials of the Romanian journal “Technium”. Of readers was attracted by the subject and documented in the design. Many are interested in the details of the devices bostanova, asking how to make the individual nodes. Further clarification and recommendations for possible solutions to the structural elements gives our consultant engineer P. Zach.
