In the “M-K” is not just talked about different designs and the complexity of the tillers. They were mostly two-wheeled options. I think that the homebrew in vain underestimate the dignity of the unicycle scheme. Indeed, such a cultivator is a simple, inexpensive to manufacture and operate, lightweight, and therefore less soil sealing, maneuverable — able to work where two-wheelers do not go, and finally, it is convenient to storage — you can hang it with a bracket on the wall. On the other hand, such a scheme places high demands on the layout of units, since the position of the center of gravity of the machine in longitudinal and transverse direction determines the ease of working with it. When installing the engine over the wheel — even of small diameter — the overall center of gravity is too high. In addition, the relatively small weight of the required traction wheels with the ground a mere development of the cleats is not achieved. The solution to both problems is to shift the engine forward. This provides the minimum height of centre of gravity and at the same time, there is an allowance of force pressing the wheel down due to the balancing pressure of the operator on the handle. The extra traction helps in the cultivation front of the working body — the horizontal legs having a negative angle of attack.
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.
For his bike, I chose a folding bike “Desna-2” In model-849 with smaller wheels (20 X 1.75). To install it on the motor, did some fine-tuning.
The laboratory experimental machines Orlowski city Palace of pioneers named after Yuri Gagarin a lot of interesting and original works. At the regional exhibitions NTTM they attract the attention of visitors of all ages. And no wonder! The search range of the young designers wide: training glider and walking robot, a flying car and microtracker. With every new car the guys are in the way of true researchers: outlining the purpose, carefully studying the existing experience, then, given their own capabilities, define the technical requirements to future design and finally design and build it. So was born a twin recumbent LEM-05 (laboratory of experimental machines, 5-I model), the creation of the device, which says the head of the laboratory of engineer V. I. Borodec.
