“Manual labor is performed by machines!” — under this title was published in our journal materials from the all-Union conference VISKHOM named after V. P. Goryachkin (see “M-K”, 1982, № 8). The performances of the participants on the importance and necessity of development of means of mechanization of cute, the editors have opened a correspondence “round table” at the same time, we invited readers to send drawings and diagrams of their machines and asked to share the experience of their construction, manufacture, operation.
Give the word Victor A. Chirkov, Amateur designer of the suburban town of Lotoshino. He has accumulated considerable experience of creating small tools today introduces its latest development — a mini-tractor MT-5. It seems that novice designers would be useful for some considerations V. L. Chirkov on the design and Assembly of such machines, the use of serial components and parts.

The conventional electric soldering iron (100 watts, voltage 220 V) through the use of technological replacement of nozzles turns into a versatile tool that allows you to perform several additional operations. Here is a description of several tools and ways to apply them.
There is an element of design, which can be found probably in any moving models. It is the bearing. Often a pair of “shaft — hole” presented in the form of passing through the wall of thin sheet metal or metal wire axis. This couple meet on the microplane in the system control cord the aircraft or in the nose bearing rezinomotornaya, and the boat, built by children’s hands, — the bearing of the prop shaft or hub of the rudder, not to mention the suspension of the microcosm novice automodellista.
In suburban areas, though small in size, usually have enough space not only for the vegetable garden and berry bushes, but I cultural grassy lawn. And he also needs care: every two weeks we have to mow. Pondering the mechanization of such mowing, paid I attention to is perched in the corner, an old floor polisher P-2. It’s almost ready based electrocoil a powerful motor 350 watts. I have set a goal to make the design such that it was possible to quickly assemble, disassemble: “translate” foot in the mower and Vice versa. And formulated the problem like this — equip P-2 circular knife and put on wheels. That is the main work consisted in the fabrication of the chassis for future mower.
Kitchens in most of our homes. Set of kitchen furniture is too small and rather monotonous, if not standard. But utensils and other kitchen household utensils is enough to place it in racks and cabinets is no longer possible. And while the hosts still want to see all the accessories were in sight and at hand. Home masters have long found a way out of the situation and came up with various brackets and rod with hooks for suspension on different devices. Picked up this initiative and the industry which produces the whole sets of symbols at once with ready-made brackets or rods. Well what can we say about this — Yes, comfortable and beautiful. Just attach all of them, as a rule, to the walls, and the walls are in turn tiled — beautiful and not cheap, drill where the holes for the dowels just don’t raise a hand. Yes and post on these lodgements “emergency” devices is very problematic.
Wings, like aviation, has already appeared on the car. At first it was a triangular plane, similar to the fins of fish. The intent of the designers, like “architectural excesses” was to give swiftness appearance. Then, when the car began to compete in speed with the wind on the wings remembered again. Only now they were needed to help the car better “hold” for the road, push him to the ground. The fastest, now not only establish a plane, located above the rear part of the body, but the front of the front wheels to the track pribavlyaetsya small side wings.
Is there any reason to go into specifics slip “school” model, results of which did not even contain the cells in the table of records! If you think about the future, that is. Today we record events are not logged, tomorrow, and the theory of sliding automodelisme not yet developed by anyone, although microcontrolle subject to the General laws of physics.
As a rule, such date if marks any event, it is certainly not prosperous. But with the first British jet bomber “Canberra” the opposite happened: it was Friday, may 13, 1949 he made the first flight, and more than half a century faithfully served on different continents. Here and believe after that in signs!
