Every year our industry produces more and more cars. Today while driving to meet a man of almost any profession — the engineer, doctor, architect and worker, farmer and teacher. On how to properly operate the vehicle, i.e. when to change the oil, how to choose candles, what to do in case of certain faults, see the respective manuals and instructions. About the little things, facilitate the daily care of the motorist, they write, unfortunately, is not enough. The purpose of this publication is to some extent fill this gap.

Domestic micro-motors RITM respond well to tuning and boost. This is evidenced by the experience of the laboratory of auto modeling sport of the Tyumen regional syut. The results of the control runs and competitions brought the engines showed that the power of engines increased, easier to run them in winter conditions. Models equipped with these engines, developed more speed. To Refine selected and tested engine with good compression, giving the stand 12 000-12 500 rpm with a propeller Ø 180 mm and a step of 180 mm.
This publication, we discovered in our magazine the best models of the competition “Experiment 78”. I hope that our readers are using these materials, prepare an interesting model for the competition “Experiment 79”, which will be held in Izhevsk in July of this year. To participate you must hold a qualifying competition. The winners of these meetings will form the team “Experiment 79” your area, region. Look forward to hearing about how he held a local competition in experimental models.
In the Arctic tundra and in Antarctica, the snow-capped mountain slopes and in the forest most of the year working tirelessly snowmobiles — reliable support person. The combination of a lightweight gasoline engine, V-belt CVT and rubber tracks — that is, essentially, the whole wisdom underlying most of these machines. At first glance, not too difficult combination. But it took a lot of time and labor to make this “Troika” to work together.
Many model airplanes-students dream to provide their own model gliders hooks for dynamic start. Designs that have already been published, quite complex for the manufacture of novice modelers.
holiday cottages or dwelling houses of the manor type of water is generally pumped from wells or boreholes. Heat it for domestic use often in electrotechno (pass-through or cyclic action) is a relatively inexpensive and convenient thermal devices. However, offer the industry’s elektrolitny designed for “soft” water with low salt content. And well or borehole water is usually “hard” (and therefore delicious) because it dissolved salts of various elements, particularly potassium. When heated, this water (especially boiling), the Heaters (thermal heaters) in the titans quickly covers the gray “fur coat” — scale, which impedes the heat transfer.
The disadvantages road bike in the first place I take them is small compared with the sports speed. But it would be nice to have a universal machine that could confidently move around the track at the same time not yielding at speed on the highway sports. To that end, I put on the bike “Ukraine” of the speed switch (see figures). In the final version of my bike has got five gears: sprocket 48 teeth driven by 21, 19, 17, 15 and 13 teeth. The car has already more than 4000 km of Any of the positive qualities of a road bike she lost, on the contrary, lowering the first transfer of the eased motion on the lane. The speed on the highway has increased significantly.
In recent years, increasingly popular among young people acquires a new exciting sport, something akin to the classic surf art of the slide with the crest of the wave on the Board. It is also used Board, however, somewhat smaller. At its bottom secured four rubber-coated roller. As you’ve probably guessed, the slide on this Board with ocean waves and asphalt, using the natural slope.
Manufacturer of air screw requires special precision and accuracy. The proposed device will greatly facilitate your work: processing of the pressure surface of the screw with sufficient precision and surface finish takes no more than 10 min. Fixture mounted on the lathe TV-4, common in school workshops and on suit. The mounting base of the copier fixed with two screws and the caliper longitudinal feed of the machine. Copier consists of base, gon and coperni line, bolted. The copier is moved right and left against the part and the fixing bolt screwed in the back.
