Treatment of soil with electrofret. Especially for owners of cottages, gardens, gardens (see, for example, “M-K” 3’83, 1Г90). And in conditions when the prices are steadily rising, when the use of tillers (not to mention scarce mini-tractors) sometimes becomes economically feasible, electrophotonic on small plots of land, that is, out of competition. Convenient and relatively inexpensive, besides, equipped with special devices, they not only allow you to loosen the soil, to weed or hoe the plants, But also to successfully complete a number of other necessary household works.
AND FURROW AND PIT
Increasingly, the editor receives letters and phone calls with the same request — to publish drawings and to talk about how to make your own hands a simple mill. The need for this device experience not only rural residents, but also citizens. “Modelist-designer” told you about the homemade mukomolno. We offer another simple design — Arkhipova, our readers, from the village of October in Nizhny Novgorod region.
My burner — ejector for high temperature soldering. Running from the LPG cylinder. It is economical: the number supplied to the gas ejector can be adjusted. The burner is arranged in the following way. From the gearbox or gate valve on the cylinder gas is fed through the hose to the inlet tube built into the base of the burner. From there it flows through the vertical channel of the rack in the Central bore of the body of the jet, where the amount dosed adjusting needle mounted on the threads of the housing cover. Further, the gas supplied to the nozzle and ejected through the hole.
“Mini tractor, description and sketches of which were published in No. 3 of the journal this year, I really liked it. As, apparently, the other readers of the “M-K”, there was a desire to make much-needed in an economy car-wagon. Moreover, because the engine pumps, and Azovskoe the clutch, and main gear from the electric cars available are already available. Constrains only the lack of information about what the suitable mini tractor front axle, frame, support system. I will be glad to read about all this on the pages of your favorite magazine.”
In one of the reports of competitions rocketmodeler I noted an unusual model sports class Ѕ6А famous athlete Nikolay Sergeeva from Belgorod. How many know it, and you know we have more than 30 years, never ceases to amaze his creative imagination. Was no competition, so he brought them his “brand” new. So it was this time.
One of the main sources of environmental pollution is the vehicles. Therefore, constructors have a natural desire to create alternative, environmentally friendly means of transportation, which fully applies and recumbent. As the basis of its development, we adopted the design of the velomobile V. Mazurchak (“modelist-Konstruktor” No. 10 of 1987). But the technical capabilities are not allowed to repeat the machine one to one, we are particular to this and not sought. Besides, from the point of view of “strength scientists”, analog velomobile is, in our opinion, not very successful scheme of loading the important elements: the junction of the front and rear parts of the frame and the axis of the rear wheels, which can cause breakage of parts or assemblies during operation. But I wanted to make the car reliable (and therefore is durable) and thus to meet at least 20 kg of weight. The velomobile was to have such dimensions that enable it to pass under a standard door of the apartment and fit in a regular (not cargo) lift. Well, that was easy to transport and store, wanted to make it more collapsible.
Today we continue the theme begun with the publication of non-traditional polyopia supersonic fighter-interceptor MiG-25, the New development even more unusual in the choice of the prototype for the copy and overall design of the model. Today, it is about the reproduction in miniature of a legendary airplane “Voyager”, made in 1986 by flying non-stop around the globe. I hope that ego of publications will contribute to the revival of some extinct interest to the class “school” sports polycopy. It should again be noted that Voyager, like the MiG-25, only a single instance of a large number of interesting prototypes, giving modelistica up at any level.
