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.
This two-cylinder engine, which received the name DD-700/40, designed and built the head of the public design Bureau “Aerocam” George Dorfman. The motor turned very good: reliable, relatively simple, easy enough.
…Lined up at the edge of the pond, the boys tensely listened to the pre-launch countdown seconds. In the right hand each refined model of aeropittura, left index finger slightly trembling, touching ready to spin the propeller. Finally, the command: “Start!” Engines do not fail young athletes; almost all microSD rush to the opposite shore. And what is happening in the ranks of the fans!
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.
Continuous improvement of engines and circuits cord boat allows them to develop increasingly high speed. Along with the design changes and the appearance of the apparatus Particularly dramatic changes have undergone recent high-speed model with aerodigestive. But in the class A1 scheme over many years remains, essentially, unchanged. Most athletes prefer to speak with a reliable traditional pattern: vertical location of the engine at the main building, equipped with two additional floats. The most careful attention is paid to Moto installations.
The proposed design is the winner of one of the contests of velomobiles in the Lithuanian city of šiauliai.
In the “M-K” No. 4 in 1983 was about a cord of car-class copies of “rally”, developed under the direction of E. Voronin. The design proved so simple and reliable that are built on published drawings of a micro-Skoda is not the first time, always steadily showing high results. I especially want to mention the original and again is extremely simple in scheme and execution of the automatic control (hold set) speed.
