Small red-hot spiral, fed by electric current, in skilled hands becomes a kind of pencil, which is burned on the tree. This elektrovyzhigatel. For its production you will need a transformer, step-down the voltage to 220 V to 2-4, 1.5—2 m stranded wire (cord), electrical tape, nichrome wire Ø 0,5—0,8 mm with a length of 60-80 mm, wood 30 mm 0 blank or cut of the PCB [plywood] with a thickness of 7-9 mm, screws and M3 nuts, small screws, strips of brass of 1 mm thickness, twine. We offer our readers two versions of elektrovyzhigatel, and each is characterized by simplicity, reliability and safety in operation.HOT PENCIL

In one of the shows can viewers was submitted to design a universal machine, designed by the engraver of the suburban town of Troitsk Y. M. Orlov. Not only a discussion of a design program participants, but also by the numerous letters received by the author, editions, TV and the magazine “M-K” showed how great the interest was this table versatile machine capable of performing a number of operations for machining a variety of materials. To meet numerous requests, the editors asked the author designs to tell more about it.
Designed for parts that are in processing it is necessary to fix in an inclined position. Clip design is simple: to steel base welded corners-brackets; on a coaxial screw-clamps rotated box, which can be installed in a wide range of angles.
The design intent of the car-Roadster FOX was born in 2004 from his youthful ideas to build an open sports car with an original appearance to satisfy personal design ambitions. During my school years I was engaged in self-similar sports, a multiple winner of the Championships of Russia. Studied at Yaroslavl Polytechnic University at the Department of internal combustion engines. There’s also graduated from the graduate school. Now I’m chief engineer at a firm which deals with composite materials (fiberglass and carbon fiber worked in high school, being a modeller). Design various non-standard equipment.
Circle carting of the Palace of pioneers of the Bauman district of Moscow one of the leading in our country. The team of the Palace is constantly among the strongest kart USSR. But a good reputation in the circle is responsible not only for his sporting achievements. He is known for his homemade racing micro cars. It would seem that anyone today could surprise card build in any more or less equipped laboratories. However “kruglikovsky” (by the name of the head of the circle) of the machine compares favorably to similar.
In the modeling practice is often necessary for the creation of ellipses of various sizes, with different ratios of semi-axes. There are several ways of constructing such figures. But they are not without drawbacks. Well, I offer reliability and simplicity. However, the required pantograph is a device well-known to widely used. Moreover s requires no change in its design.
In the cottages to place a convenient staircase to climb to the loft difficult. And the output, it turns out, there is. He is to use long-known designs parallelogram mechanism which is sometimes used for attachment of the wall lamps. Only in our case we need two such devices, connected by rails. It is convenient to use as rungs of a wooden rolling pin. At their ends, holes are drilled where the glue is placed on the metal studs. The ends of the amplified thin aluminum rings. Step of the steps is selected so that would the stairs were easy to climb and big and small.
The wing of any aircraft should be smooth. It is clear. But how to achieve this? Each athlete solves the problem on its own. Beginner difficult — AA he has no more experience, eyes ve learned to distinguish the slightest variation from the ideal planes, but random twists and curvatures of the wings should not be.
