The easiest kayak in comparison with it will be two to three times heavier. Folded it is less than any inflatable boat. But to sail on the catamaran can be together, as on a good kayak. And for cargo space. If you want easy to put a small sail. In serious Hiking it can be, and will not go, and for the weekend very comfortable craft.
Using the experience of previous generations, lifting them achieve a new level of quality, the development of scientific thought is moving up in a spiral. Not accidentally, the inventors, creating increasingly sophisticated machines, often return to the experience of its predecessors — rely in their search for designs of bygone years.
The plane “pilgrim” in the Tver club “Aviator” was conceived in 1978. He was born in the debates and discussions. In the end, it was decided to build it in the scheme of “Demoiselle” in flight technology: soft dual wing. The design relied on overloading the +8 and – 3 (destruction). The horizontal tail was taken in the range of 2 – 2.2 MAR. The original wing that the ribs to the spars are fastened, and inserted into laderman fabric covering.
First of all we should warn all those who want to do the same spinning wheel that required minor changes in the sewing machine does not affect its appearance and, importantly, does not damage its main purpose is to sewing. The principle of spinning on a homemade electric machines, braking of the bobbins relative to the flyers — and here, of course, remained. Therefore, preserved the basic details: bobbin, rotating the spacecraft Central axis; a device that acts it; the bracket with the guide hole; flyer with hooks — though all in a somewhat modified form. The rotation device receives the ha score of the flywheel of the machine — in this lies the main “trick” of the design.
We left a tireless worker submarine building John Holland at the end of the XX century, at the time of his career, when the impression that finally his long labors were crowned with success. Indeed, he created the submarine, named with his own name, finally became part of the United States Navy. On the stocks of the company, also bearing the name “Holland”, built next boat, the ninth, in which was made additional improvements. It showed the interest of Maritime agents of some foreign powers when the mounted body only. It seemed that one more step and the production designer will be able to break the “operating room”.
When drilling in ferrous metals, blind holes, and especially cutting them in thread, at the bottom remain shavings and sawdust, which is not so easy to remove, especially if the part is massive. “Call” to the aid of the magnet and any steel rod – you can even blunted nail or screw. The terminal will Read more…
It is known that in house conditions to solder aluminum products is not easy: tinned stripped space prevents instantly formed when Stripping arisia film. To remove it use acid, steel sawdust, and more. Methods of brazing of aluminium are countless. But they are good only for the particular case. The method that appears to be Read more…
All wars end sooner or later, no exception and the most terrible in human history the Second world war. And when peace came, the experts were not in a hurry to understand tendencies of development of those or other weapons systems. It is obvious that during the conduct of hostilities, the release of new models of equipment and retraining of personnel on long-term patterns difficult to achieve.
The ATV is made of that which was in the garage. Generally in the construction tried to use as many parts from domestic cars. Yes, and that turning was smaller. Engines with gearbox (welded differential) – from the car “Oka” VAZ-11113. Quad – double. Seat though homemade, but made on the principle of the factory – the passenger sits slightly above the driver, it has the backrest and footrests.
Perhaps the desire to dress up the light source comes from the primitive worship of the miracle of fire. Even the torch could just be stuck in a split stick, and you can revive the thread and patterns of vertical Board designed for this, and a primitive lamp not only gave light, but decorated home. Today, perhaps no one kind of industrial products for everyday life has such a diversity, such as lamps: chandeliers, table lamps, floor lamps and wall sconces, lamp shades, lampshades, diffusers of all kinds, lamps, different from each other at a common decision, form, material, colour. But to satisfy our demand is impossible — so the effect here individual taste or particular living conditions: purpose, place, environment furniture, existing light sources.
