Whether on forces to build a yacht for the beginner to sailing matters, having in disposal only the materials from the stores “Do it yourself”? The main problem that he faced at the beginning of their labors, is the choice of design of the future vessel. Once a few years ago in a similar situation, I decided that the easiest way is to make the sailboat of the tourist serial portable kayaks. And of all the published canoe designs the most attractive seemed to me project boat-trimaran.
TRIMARAN UNDER THE TWO SAILS
“When I recorded “Jisu” in the traffic police, major-inspector to find fault with the documents did not. I leafed through them and said: “let’s Go see your car”. Walked around it, looked under the hood, under the bottom, then sat in the cockpit and says, “let’s Go!” We got on the highway, ride. At the end of the major shows on the hill: “got it?” I’ll try, I say. Began to climb. Passenger my stiffened in the seat. Yes, and I was not myself — the slope is almost 45 degrees, almost lying on the backs… But “Jessa” — well, climbed to the top. Where now, you ask? Major briefly: “MREO”. Then quietly, as if to himself, said: “Here not even a single vehicle is not stopped. What else is there to check?!”… From the story of the designer of the vehicle V. A. VERBYLA
Advantages of welding machines DC before they “perimentally brothers” is well known. It’s mild arc, and the ability to connect thin-walled parts, and less spatter, and the lack of nepreverjenih sites. Even the annoying (and, as it turned out, bad acting people) cod is not. And all because there is no major inherent to the welding apparatus of the alternating current feature — intermittent arcing at the overflow of the sinusoid of the supply voltage through zero (Fig.1).
I recommend readers of the magazine is easy to count, easy to manufacture and very reliable electric soldering iron. At my house, for example, these range from “krohotulki” for work with microelectronics to powerful “ax” with which to patch a leaky metal tanks, repairing wells, filters and other large items. Moreover, the heating element of each electrical device is… the appropriate power resistor (type PE or PEV), powered by household outlet voltage is 220 V. the resistance, if they cannot be avoided, reactive, precise, capacitive, allowing to solve very complex electrical problem with the minimum dimensions of the devices.
It is not an exaggeration: the basis of all of these designs really stepladder. However, originally arranged, which allows to obtain the transformation. Like all sliding ladders, it consists of separate halves having a top swivel. But that’s where the similarity ends. Next come the features that make the ladder universal fit to build the structures that are needed. In particular, for children’s room or for the garden.
One of the inconveniences in the design of many cars is that the interior light goes out immediately when closing the doors. There are, however, a special device to delay the power light on 5-15 that the driver had time to explore the dashboard controls and to insert the ignition key. But these developments are usually complex and expensive. And reliability often leaves much to be desired.
