Every gardener strives to heat their greenhouse as efficiently as possible. One of the most optimal methods is utilizing solar heat accumulated by the southern or eastern wall of a stone house. Building such a heliogreenhouse is quite simple. First, a trench is dug along the wall of the house, 1.1 meters deep and 0.8 Read more…
“I read in Modelist-Konstruktor about the continuation of the “Small Mechanization” competition and decided to take part. I offer a simple and compact micro-mill. Its dimensions can be judged from the photo: the entire construction fits in the palm of my hand. It’s a universal device — designed for producing both coarse and fine corn Read more…
Dear “Modelist-Konstruktor”! In issue No. 9 for 2004 of your magazine, a material was published about a compressor I made based on a motor-compressor from an old refrigerator. I used it for several years for various needs: paint spraying, tire inflation, and other tasks. But sometimes it lacked pressure and air reserve. Then the idea Read more…
We have already talked about agricultural machinery that used an electric drill as an engine: mowers – rotary and with a cutting knife (see No. 9 for 1980 and No. 2 for 1981), a plow with electric traction (see No. 9 for 1981). Now we offer a new design on the same base – a Read more…
A moped is often considered an expensive toy for children. And in fact, a significant portion of these two-wheeled machines are purchased by young people for purely recreational purposes. And only a small share of mopeds are used as a means of transport for business trips. And what if suddenly there is a need to Read more…
The experimental winnowing machine-sorter is designed for selection work. The winnowing machine body is made of pine beams, to which the side plywood walls are attached. The beams are assembled into a tongue and groove in half a tree. The receiving bucket is equipped with a flap, the movement of which regulates the grain feed. Read more…
The All-Union Competition “Small Mechanization”, held by the editors of the magazine “Modelist-Constructor”, has gained wide popularity among the creators of small-sized agricultural machinery. Many of the designs presented by its participants were awarded (see “M-K” No. 4 for 1987), and a number of developments were recommended by the editors for display at the Central Read more…
I probably won’t surprise anyone by saying that preparing firewood for the winter is one of the most labor-intensive tasks for a rural resident. Of course, it’s not at all easy to cut several cubic meters of wood! Is it possible to turn my old motorcycle into an assistant? The idea seemed tempting, and I Read more…
Among the responses received to the All-Union competition “Small Mechanization” held by the editors together with the Central Committee of VOIR, there are many letters asking for the publication of designs for household installations using wind and solar energy. The interest in these devices is understandable. It is caused by the vital need for this Read more…
Mechanical saws produced by industry certainly make the work associated with preparing firewood for the winter easier. But most of them have one drawback: during operation, the entire unit along with the motor has to be held in your hands, which not everyone can do. In the proposed homemade design, the entire power plant is Read more…
