POUNDING, SO GOOD!

Many models can be made to forgotten the method, by squeezing the sheet metal. Extortion is used for any thin-walled parts (e.g. fairings, cowlings, shrouds, wings, wheels, and similar). Often they are made of brass or aluminum alloys. The material is pre-annealed with a pair of scissors and cut the workpiece with considerable allowances. The tools serve as a mandrel, anvil and various hammers. The process of knockout s is the stretching of the material when its thickness decreases, and in the sediment, which implies an increase of the thickness.

Tugs and spare wheel

I suggest the owners of motorcycles IZH a simple design of the towing device is constructed as a single unit with a mounting bracket, a spare wheel. Despite the fact that between the sidecar and the bike is not too much space, “reserve” does not interfere with passengers on the rear seat.

FLYING WING “JUNIOR”

In our circle beginners-students who have gained initial skills training cord model engine MK-17, traditionally entrusted with the Assembly of models of air combat with the same engine. In this sports class is most often used layout type “flying wing”: lomikami wing and Elevator on the trailing edge of the wing. Spar-wall this model is made from spruce, pine, aspen or lime plate thickness of 2.5 mm, and the rear edge of the wing—rails section 12×3 mm. the Latter consists of centroplane and console parts. Joints edge definitely wrapped thread and impregnated with glue, or with rough landings inevitable failure. The wing tip is made of plywood or wood plates with a thickness of 2.5…3 mm is recommended to facilitate Their holes. If the rib is cut from plywood, the edges are not required.

FROM THE RIVER TO THE SLIPWAY MODELER

German 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.

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

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

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

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).

WINCH: PLOWMAN, KARCZEWSKI AND… MINESWEEPER

“Harnessed… the winch” — under this title was published in the “Modeller-designer” № 8, 1995, the material on the system that I designed of selectresponse. Not the last role in it plays a towed plow, the design of which proposed to make a very lightweight (less tired during the transfer to the beginning of each furrow). And now I propose readership new variant of the plough-“feathers.” A lot of it is really small — 13.7 kg (excluding handles), plus optional (for a better entry into the soil, cutting and turning layer) and 4.5-kg weighted. From my earlier designs and prototypes, the author of which is G. Odegov from Nizhny Tagil (“modelist-Konstruktor” N9 6, 1990), the proposed design is the presence of a deep notch in the working body, significantly reduces the resistance of the soil, and a number of other technical solutions.
