PLOW: LOOK FORWARD AND MAKE OURSELVES

PLOW: LOOK FORWARD AND MAKE OURSELVES“The walk-behind paired with the transport carriage (thanks to “M-K”!) made. And now to get-to bring something on the farm for me, as they say, no problem. But good plow still on the road. Wait till the pages so my beloved journal will appear in-depth material on how this plow to calculate and do it.” Similar requests requests come to the editor a lot. Apparently, from those subscribers who failed to see the previous performances of the journal on particular topics (see, for example, “M-K” 1’88, 3’89, 9’90, 5’91, 10’91). And so — a new publication dedicated to the ancient and, as evidenced by life itself, timeless tool of the husbandman.

CURLY SAW

FIGURE SAWTo complete the profile of woodcarving, offer readers a “M-K” to assemble a simple machine based on the electric drill IE-1036Э with electronic regulator of frequency of rotation of the spindle. This mechanical almost universal, it is suitable for cutting curly proraso as wood and metal. To make it simple saadeldin, with experience on machine tools drilling, turning and milling. To jigsaws will need a pair of gears (Z1=14 and Z2=40), bolts, bearings, pipe pieces, a piece of steel channel, steel plates of various sizes.

HOW TO MAKE “ZIMMERIT”

HOW TO MAKE Anyone interested in the history of armored vehicles is well known that highly characteristic feature of the external appearance of the German tanks since 1943 was an anti-magnetic coating of armor — so-called “zimmerit”. Originally this coating was intended only for the Eastern front, but soon became an integral part of all tanks of the Wehrmacht. “Zimmerit” with a rather complex chemical composition, in simplified form, is represented as a mixture of latex with cement. The idea of such a coating is rather controversial, since the magnetic mines were used only by guerrillas, and after application the tank was still “clean” place (rollers, tracks, etc.). In the end mine was “to stick” and to railway platform, and downhill equally flew echelon with tanks, as with the “Cimmeria”, and without it. But nevertheless, the Germans did it quite costly.

COFFEE? SEEDS? 10 MINUTES!

COFFEE? SEEDS? 10 MINUTES!For those who like roasted seeds or coffee beans at home, but do not want to waste time to stand at the stove with the continuous turning of the upcoming Goodies, I recommend a simple and reliable technical solution. Its implementation will require microelectronical, a double reduction from some broken mechanical toys, self-made metal tray is a sieve and a couple of strands of steel wire. And yet, ten minutes of patience to put it in a workable structure, as shown in the figure.

ANTI-THEFT – IN 5 MINUTES

ANTI-THEFT ALARM FOR 5 MINUTESAfter reading No. 1 “M-K” for the year 1989 description electronic switch-off “weight” of the car, decided to use it as a simple anti-theft tool. However, the replacement of toggle on the button (as advised by the project author V. Arapov) or reed switch occurs very undesirable moment when the voltage produced by the generator will be equal to the battery voltage, the transistor closes. And in the future on-Board vehicle network will be powered by only one generator. And as for fuel economy the engine is regulated to the minimum idling speed, the voltage generated by the generator in this mode, will be low. Therefore, at the moment of starting off (as in a “weak” generator, and when the light is turned on) the engine may stall. But the main danger occurs when emergency braking, as when the engine stops, the on-Board system is de-energized and the brake lights do not burn!

NEW TECHNOLOGY

NEW TECHNOLOGYWith all the advantages of fiberglass hulls for model rockets the traditional process of production is highly labor-intensive and unsound. Meanwhile, the conversion gave the modelers a new and very interesting material is heat resistant fiberglass gasket STP-4. It is used widely and, having a small official shelf life, often charged and often goes to the shops “Junior technician” or “Do it yourself”.

FLIGHT ELECTROLET

AEROBATIC ELECTROLET

Judging by the letters from our readers, the interest in the model aircraft with electric motor is not reduced. Comes a lot of questions about the challenges of producing interesting flying machines and development of specific projects. One of them we want to acquaint the followers of electroperu. Very effective control line aerobatic model created by A. SUHANOVYM from the city of Astrakhan. In addition, they built “nilotica” interesting minimal use balsa, which gives the possibility of playing in almost any conditions. If necessary, balsa items without much damage to the mass of the model can be replaced made of lightweight Linden (in this case, TopMenu blanks should be reduced in half to two times).

TWO FIGHTING WING

TWO FIGHTING WINGDeveloped in the circle of aircraft modeling station of young technicians of the city of Berezniki of the Perm region and the following proposed model of “air combat” is designed for mid-level athletes. They are distinguished by a good performance, sufficient strength and manufacturability. But for some modelers who do not have experience with foam lomikami or do not have access to the material of the required quality, it may be advantageous to use as the main material lime veneer (which, as a rule, can be made independently). Both bouzouki built on a “flying wing”, dominant in the Junior class and sports the “air battle” of the last decade.
