IS-3: THE LAST BREAKTHROUGH TANK

IS-3: THE LAST BREAKTHROUGH TANKDrafting of a new heavy tank, much superior to commercially produced is-2 on armor protection began in accordance with the decree of GKO No. 5583 on 8 April 1944 and had its prehistory. A group of researchers of the Military Academy of mechanization and motorization in the name of Stalin, led by engineer-Colonel A. Zavialov studied in the field of tank battles the battle of Kursk, the nature of the damage caused by the shells hitting tanks. It turned out that not all parts of the tower and was amazed the same: more suffering frontal part, while the number of hits in the tower was the greatest. The result of these studies and was the project of a new tank.

FROM THE RIVER TO THE SLIPWAY MODELER

FROM THE RIVER TO THE SLIPWAY MODELERGerman river motor yacht “bar-new” (Warnow) was the inspiration great procopii, equipped with an electric motor and two channel radio control equipment. She was repeatedly reproduced by modelers and enjoyed great success at competitions and demonstrations. In the absence of radio equipment with the model it is possible to speak in the classroom “bramahadev”. The design model is simple. With its manufacture and Assembly can handle every aspiring constructor of ship models. The case is of classic design, stacked wooden. Collect it on the epoxy. Mounting up the keel on a flat Board-berth with a fixed drawing with the layout of the centerline and locations of frames from the 1st through the 6th. All of the parts of the frame previously marked in accordance with drawings, cut out and treated.

YOUR WOOD-MACHINING

YOUR WOOD-MACHINING

Delivered to readers a woodworking machine I own was designed, personally manufactured and now successfully use when building a house on his land. See how successful the design: compact.technologically, it seems suitable to “replicate”. The machine is so simple that sverhusiliya detailing for its production are unlikely to be needed. For all the attachment here free access. So if you want the design can be easily disassembled and transported in the trunk of the car, collect in a new place for thirty minutes.

THE TRUNK PLUS CASE

THE TRUNK PLUS CASE

For the motorist the trunk of the car is not only convenience, but also a number of related problems. And first of all — observance of the required aerodynamics. The fact that in certain species, despite their seemingly openness, the trunk creates an additional “windage”, increasing wind resistance even at low speeds. This means additional expenditure of gasoline, the price of which today is “bite” harder. To remove the same and install it every time — the extra confusion. And should be placed in the trunk of even a small load — even larger impact windage.

RADIOPLAYER: HOW TO FIND THE OPTIMUM

RADIOPLAYER: HOW TO FIND THE OPTIMUM

Now we can safely say: RC model become the most popular in our country, turning from an object of elite hobby at a relatively affordable hobby for many athletes. The reason for this is the emergence of both simple and complex, and most importantly — reliable control equipment. Now, according to experts, the number of “cordovil”, “svobodnoradikal” and “radio operators” as a first approximation, equal. More important was the question of where to start entry into the most difficult class RC. The theoretical directions and schools here, there are many. But. it seems that there is no more reliable and “bloodless” (the number of broken during the development of radiobiology models) than the traditional, based on a gradual transition from simple gliders to more and more complex motor vehicles.

“BEETLE-42”: THE TRANSPORT OF HEAVEN AND EARTH

From experience we know that the appearance of ultralights “beetle-42” generates a lot of emotion and, of course, questions. Emotions lower, and all of the many issues leave one of the most significant: why is he not three-, and four-wheel chassis? Before you answer, remember that a vehicle with a tricycle landing gear and a forward driven wheel is unstable on turns and uneven ground and prone to rollover. The same can be observed in three-wheeled Beltelecom in the most critical modes of operation — the landing. And especially on unprepared sites. As practice shows, from tipping there, no one is immune: not a beginner, nor a master.

PRISTINA… TO THE BIKE

PRISTINA TO THE BIKE...It all started with the fact that we are a young childless family bought two “Kama” and became interested in Cycling. With the birth of his daughter had to solve the task: how to travel together? Did a little chair, and set it on the rear trunk. It has served us faithfully for several years But the daughter grew up, and sit in the car seat she was cramped, uncomfortable, the idea of creation of easy folding, durable enough trailer stroller, quickly attachable to the bike.

THE COMPRESSOR FROM THE FRIDGE

THE COMPRESSOR FROM THE FRIDGE

Dostoinstvo spray gun is known: it provides high-quality coverage. In addition, to achieve smooth transitions from one color or tone into another is possible only by spraying. And for that you must have in a home workshop air compressor. It will not idle and after apartment, and will be useful for inflating chambers of the bike and car, spray fertilizers on the garden soil.
Not necessarily the purchase. I read once in the “Modeller-designer”, because of the refrigeration unit, overage, you can make compressor. It said on the construction of serviceable electric motor. I also got burnt. So had to settle for a piston mechanism. To remove it, cut the casing in two places with a hacksaw. Then by unscrewing the four mounting bolts, removed one side of the stator and the pump rotor. Because the rotor is no longer needed, he was knocked to the crankshaft.

CUT AND WELD THE WATER

CUT AND WELD THE WATER

Device for gas cutting and welding a variety of materials including refractory metals, no agriculture, I think, not hurt. The more compact and completely safe to handle. But where to get one? Yes, and too expensive for many to acquire it.But the proponents of mechanization — lovers to create everything with their hands such a device is certainly there. Perhaps even homemade, made according to the sketches and taking into account the recommendations that have been published in the pages of “Modeller-designer” (No. 7 of 1980 and No. 10 of 1985).
