The journal “modelist-Konstruktor” already published materials created by skilled craftsmen in Altai region opposed two-cylinder engines with integrated gearboxes (No. 3, 1987, and No. 8 for the year 1989). Now — the story of the machine for which they are intended, as well as an improved engine, M-40, assembled from parts motorcycle motors IZH-P-4 and Il-W-5 and tractor “poscache” PD-10.
A GIFT TO THE TEACHER
Daily Teacher have to write on the blackboard with chalk. Inconveniences that arise when working with him, related not only to the need every time to wipe or wash your hands. Chemical substances included in the composition of chalk, often cause skin irritation, and the nails become fragile and brittle. Make a nice gift Read more…
Steel sorokametrovoy a can (or jar) over time rust begins to leak, making it not suitable for storing not only food, but water. It is a pity to throw out, and not suggest. Because of the old jar you can make a good oven-“bourgeois”. However, for such a “metamorphosis” will need some more stuff, but about them later.
“The smoke of a fire creates a cozy atmosphere”, says the tourist track. Bring the magic of an open flame unites and unifies the audience by the fire people. In this sense, on a country site nor the grill, nor outfitted summer kitchen can’t compete with a simple campfire that you’d like to sit down young people and parents, and the neighbors come to the evening light. Conversations, jokes, soft soulful songs…
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. 
“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.
