“Unsportsmanlike! It is helpful to build models, not to bring equipment adult athletes! Not to allow for competition!” These indignant exclamations addressed to our children when they first presented their new microglossary in on a meeting of young modelers. We were convinced opponents and judges that the lightest devices built by the hands of boys, and not only built, but also well-designed by our sportsmen-beginners. Talked about how it was created, the new design scheme, how to construct the model. Gradually distrust, squishie in the eyes of the “enemy”, beginning to be replaced by sincere interest. But honestly, we left with the impression that to fully dispel doubts rivals failed. Especially after it started, when our gliders come with speed only slightly inferior to the results experienced athletes. And this is without the resonance of the exhaust pipes!

For the qualitative and rapid painting using airbrushes and spray guns, for many other works in the home Studio suitable table mini-compressor which can be assembled from the compressor unit of the refrigerator. Moreover, it is not necessary to use the new host is quite good and with a clogged pump valves. The main thing – would be a good motor. And you can check it easily before disassembly – using an ohmmeter, measure the resistance of starting and working windings (respectively 5 and 20 Ohms).
Good appearance good passport data, quality performance — these are produced in our country in large series compression motors CSTOM-2.5 D. But unfortunately, not every of them work confirms promised in the user performance data and the resource. Instead 0,34 HP at 16 thousand rpm with the standard propeller 200×100 mm we had great difficulty in achieve a 70-80% capacity, resources are often limited to running, bad engine run, requires careful adjustment.
High speed car with remote control and internal combustion engine for twelve year old boys? I will say, this is not serious? The creation of such machines is the “aerobatics” automodelisme available Only to qualified athletes? And then teenagers…
Do not rush to dispose of old vacuum cleaner: the motor will serve to drive crusher — indispensable assistant in the preparation of feed for poultry and other domestic animals. The principle of operation of the devices is the same as the electric coffee grinder: swivel high speed metal plate — knife slices through the grain for as long as their value will not be less than the mesh size.
Residents of the Armenian capital like cars and know a lot about them. This convinced us to visit Yerevan streets with design engineer ERISA by Stanislav Hopenosis on his makeshift Rover. Wherever we stayed, immediately gathered around the curious passers-by. Followed inevitable in such cases, the questions: what? how? from what? Stanislav patiently answered. For three years from the date of first departure on the new machine, he was used to these “press conferences”.
In different areas of our country the soil was treated in different ways. Soil and climatic characteristics, natural, imprint and on the design of small tools, which are developed by the owners of household plots. Some building microfracture and tillers, designed for the use of the plow, others motorize.
No doubt, the motor-plow or microtracker in the farm economy — assistant-all-trades. But where the plot-all small, and the garden trees and shrubs planted densely enough, the walk-behind combustion engine just to turn around. Here and come to the rescue of a simple, but very effective! the cultivator on the basis of the motor from the washing machine. Its working wheel with long narrow teeth perfectly reserves the loosened strip of land width of about 120 mm at a depth of pereopisanie to 150 mm.
Isn’t it tempting to make a motor-plow design which has almost no welds! That’s why published in the “M-K” № 3, 1985 article “the wheel of veloplugs” on how to build such a mechanism using a frame end-of-century bike, had a great response.
