The Assembly of such sofa beds only took three days, however the design was thought through in advance. Wish it was spacious for sleeping, and a day would take up less space. So I made it folding. Assembled width slightly less than a meter, and in the evening it increases the size of the back cushions (in my version up to 1,5 m). The main material is chipboard sheets, boards, rods and foam with upholstery fabric.THE BATTERY IN THE FRAME
When equipped with a headlight of a Bicycle “Salyut” there is no need to manufacture special container for batteries. It can be hidden directly in the frame, pre-SPAW three elements 343 and installing the handlebar switch. Sergei GUSELNIKOV, Novomoskovsk, Tula region.
Machine UK-4 is still popular among hobbyists and tinkerers. Over the years of its release, home craftsmen invented many devices to improve its performance and broadening the range of operations. Many of these upgrades were reported in the “M-K”. However, nothing was said about using his motor at full capacity. But it is quite enough to handle larger workpieces than the number specified in the passport of the machine. And the need for such a feature: in this we have repeatedly seen at work in our model aircraft club. Here and was made a fixture that allowed to increase the depth of milling parts using standard cutters b to 17 mm with their width up to 260 mm instead of 60.
Rust… the number one enemy of almost any metal. “Red plague”, with an enviable tenacity and persistence, transforming hundreds of thousands of tons of sparkling high grade, high strength, alloy steel in the piles of brown powder. Disease for which there are no barriers… But there are medicines and from her: electroplating, Lani and paint, bitumen and mastic — all they basically have to protect the metal. But the reality is not so simple.
There are various electronic devices to locate hidden wiring. However, at home the need for them arises relatively rarely, when, for example, produce the repair of the apartment or change the interior.
British military shipbuilding has centuries-old experience of development and combat use of the most advanced designs and technologies. On the eve of the Second world war-the British squadrons were surface ships: battleships, battlecruisers and aircraft carriers. Therefore underwater vessels by the Admiralty was not honored. However, the attack on Gunter Prina 15 Oct 1939 in Scapa Flow, when he crept into a German submarine sank the battleship right into the main base of the British Navy, put squarely the question of creating subversive underwater vehicles.
Free energy wind has long serve man. Question about using it is urgent and now, especially with the ever increasing shortage of natural fuel. There is a “demand” for it and the private sector, as evidenced by letters submitted to the editor.
Simplicity of design “Harp” is perhaps unique. In the car a total of six main parts: frame, engine, rear axle, wheels, ski with the steering rod and steering wheel. Reliability and simplicity of the snowmobile complies with the standards that apply to vehicles intended for Autonomous runs over a vast and desolate regions of the Arctic. “The harp” easy to disassemble and in the back of a truck or in the baggage car to transport to the launch site, and there is to collect hours. and a half and to travel.
The appearance on the competition models of sailing catamarans and trimarans was the natural result of the development of a very interesting class of ship models — radio-controlled yachts. First I gotorussia was built in our country in 1974 almost simultaneously by three athletes from Kiev, Valeriy Bondarenko, a Muscovite Valery Efimov and the author of this article. All mini yachts was created on the basis of requirements for models of class F5-S (with an area of 0.5 m2 sail). The best results showed catamarans. In the future, on the basis of their group Kazan modelers have worked a few designs, which already could compete with the traditional single-hulled yachts with moderate wind and have a distinct advantage with strong.
