(THE BUILD-POLYOPIA). Building the model-polyopia begin with the manufacture of the fuselage (Fig. 1), the contours of the lateral projection should most accurately reflect the similarity with the copied aircraft. To the fuselage structure demands maximum strength with minimum weight. The greatest difficulty in its manufacture is the reduction in the weight of the tail, which is much longer than the front, So it makes truss.
In the halls of the Central exhibition NTTM, dedicated to the XXVI Congress of the CPSU, it is possible to see many original designs and arrangements, created by young scientists, innovators various sectors of the economy. Is on display and very unusual exhibit — a fragment of a brick house, over which a fortified small drum with a wound on its shaft with tape. This flywheel model of lift is designed for lowering people from a height of 100-150 m in the case of fires or other natural disasters, when the regular elevators stopped because of power-cut. The device can be useful when landing fire landing of a helicopter, for example, on forest fires, when landing is impossible because of the smoke.
Snow scooter we recommend that you do, will give the opportunity not only to descend from the snowy mountains, but to engage in the slalom. To build it is not too difficult. Well, of course, if you manage to use the weld, but in a pinch you can do without it, replacing the weld bolt.
Do not consider it shameful to use a good development designers and lovers they share the magazine. But, armed with their interesting ideas and technical solutions, and the very creative approach. So for the treatment of potato between the rows was made cultivator-Hiller. He arranged for motorcycle scheme, when working on (cultivator or Hiller) is located between the two running “in the tracks” wheels: guide (“sulker” from children’s pedal cars) and leading (of the scooter Tulitsa).
The model, which will be discussed in this article warmed the soul to generations of young sailors. In the distant postwar years, and even in the sixties, such a boat could be found on store shelves. From many toy counterparts his distinguished acting steam engine in the bilge – in the furnace was burning real flame to heat up and boil water in a small steam boiler, humming quietly, pushing the boat forward, two small jet of thin tubes. On a boat it was impossible to look without admiration – he was so real! And easy the soot from the burnt fuel on the surface of the cutting gave this amazing little machine is truly a “combat” look. The greatest effect was achieved in the twilight, when at full speed in the Windows of the wheelhouse, it was possible to observe the flickering glare of the flame.
A mini-tractor, which is presented to the readers of the journal “modelist-Konstruktor”, is the third built by me. His frame is “broken”, consists of two articulated half-frames, as in the heavy tractor T-150. A node of articulation serves as a node (or mechanism) of rotation. A used engine from a motorcycle “Ural”, equipped with a Read more…
One of the most critical components of the machines crawler — tanks, all-terrain vehicles, armored personnel carriers, tractors, trucks is the suspension, particularly caterpillars. Their tapes, as you know, is assembled from separate parts — the tracks connected by fingers. Each track has a grooved surface — lugs deliver reliable traction. On the side of the track facing the rollers, is guide comb, preventing a descent of rollers with treadmill tracks the motion of the model, especially during turns.
Potato hasn’t been easy work. Meanwhile, a simple Assembly can radically transform it, making it significantly easier. In appearance he is a one-wheeled wheelbarrow, but not the usual wheel. It consists of three parts — two outer metal disks bent to the external side of teeth-lugs and the middle part, is sawn from a Board Read more…
We offer proven our ship mug method: to make propellers with electric current from foam. Simple device allows you to quickly produce a series of identical screws, which in appearance is no different from bronze, but do not sink in water.
the Conversation today will focus on the sailboat of a new type — light weight, affordable and versatile vessel-trimaran, which portable travel paddle with a soft shell. The merits of such a lot of trimarans, and one of the most important is the low cost of the kayaks and additional sailing arms. In addition, such a vessel do not require hospital car Park on the shore — enough and the mezzanine in the apartment; to deliver the same trimaran to the water is possible even on public transport, not to mention the train.
