When there is a need in the trailer for transportation of household goods, there is the problem of choosing which trailer to buy, good this choice was. That’s the only difference in price is not really felt, although the price was quite high. In the end I thought — and whether it is worth it to buy? So it’s not that complex device that was not able to do it myself. And the money will come in handy for something else. Of course, with this trailer is more of a hassle at check in, but the savings are worth it.

ON THE ICE — IN TOW
The tug skater that I have built and offer to readers, is characterized by simplicity, reliability and high maneuverability on the ice. It can be made of the most abundant materials and simple tool at home. This will require the old motorbike and some spare parts normal road bikes. The production is in one week even if you work only in the evenings.BOMB MODELS
Aerial bombs are divided into three types: primary, secondary, and special assignments. The first are high-explosive, fragmentation, armor-piercing, incendiary, and some others, the second is luminous and warm (they promote more successful use of bombs main destination). Finally, the flash bombs, the so-called practical bombs, smoke and other employees for special tasks, refer to the third mind.AT HIGH ANGLES OF ATTACK
To maximize flight time Svobodnaya model championship class, usually try to use large angles of attack. However, flying often becomes unstable due to the disruption of flow from the wing. To address this shortcoming, Leningrad Antonov an S. Matveev developed and tested in practice a system of slotted wing.“BACKSAVED” DEVELOPER
The owners of private houses or villas are often faced with the need to prepare concrete solutions. Mix in certain proportions water, gravel and cement — a simple matter, but very time-consuming, requiring considerable time and physical strength. And if you want to carry large volumes, the process of preparation of concrete or mortar becomes hard work.“TURN THE HANDS!”
This call is present in many emails of designers bikes. “Somehow, browsing in the library of old magazines “M-K”, I came across a design velocipede with manual transmission. From that day, I had only one thought — to do”, — says Sergey Titarenko from the city of Nevinnomyssk in Stavropol region.AQUAPLANE? NO, SNOWPLANE
These sleds, perhaps, the most simple design, gather them literally in half an hour. For the manufacture of snegopada will need straight grained boards 30 mm thick (200X1200); two strips — one section 50X60 mm and a length of 560 mm, and the other 30X50 mm and a length of 560 mm, and a sheet of plywood with a thickness of 3-4 mm (620X1240).IN FLIGHT — “GUPPIES”
Training control line model airplane. The fate of each Antonov an-certovica has its first model. As a rule, later he gets the ironic name of “three stick — two string”, which in fact, it is quite true because of its very simple design.
IZHEVSK “PLANET”
Izhevsk is widely known in Russia as one of the centers of the masters on the hardware and gunsmiths. And, in spite of “perestroika”, the city tries not to lose centuries of acquired knowledge and traditions and raise worthy successors. One of the enthusiasts of this noble cause — Ruslan V. Cherepnev, teacher of additional education of young technicians “planet”. Along with his students he developed and produced many original and useful designs that have repeatedly won prizes at Republican competitions of technical children’s clubs.









In the old days (but not so far) rarely does the farm did without such household storage, like a cellar or basement. The latter name reveals its structure: deep in the ground and lined on top of the ground room in which were stored grain and other supplies, and various belongings.
