IMPROVE UK-4

IMPROVING UK-4Machine 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.

THAT IS NOT RUSTED CAR

SO AS NOT RUSTED CARRust… 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.

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.

IN THE RACE – MNOGOYARUSNYI

IN THE RACE - MNOGOYARUSNYIThe 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.
