Dear “modelist-Konstruktor”! In No. 9, 2004 your magazine published an article about made me the compressor on the basis of the motor-compressor from the old refrigerator. Have used it for years for various uses: for paint spraying, tyre inflating of wheels and other works. Just not enough pressure and air supply. And then came the idea.

Many developers will be the future homeowners or gardeners — you have to solve the issues of transportation for short distances of local construction materials such as soil, sand, stone.

Dear editors of the journal “modelist-Konstruktor”. Your journal I read from 1988 (I’m now 33). By profession I am a mechanic, own a welding business, and to all, a big fan of technology. Using published in the journal of the technical development of Amateur designers, he built three mini-tractors. It was found and used some of their technical solutions, for example, a tractor equipped with gidroksila.
