The automotive trailer discussed here was built by Dmitry Pekarev. In general, he is still a quite young man — he is 25 years old. In their family, which loves to spend summer vacations actively, there is an old VAZ-2101 car and a “Kazanka” boat with a motor. However, there was nothing to deliver the Read more…
We continue the story of the machines and mechanisms built by V. A. SVERBL — an amateur designer from the village of Zelenchukskaya in the Karachay-Cherkess Republic. In the publications “Walk-behind tractor — nothing superfluous”, “A reliable helper for the walk-behind tractor” and “A compact car with the character of an all-terrain vehicle” (“Modelist-Konstruktor” Nos.

In clouds of snow dust, unusual machines rush down from a high mountain — they look like bicycles, only with skis instead of wheels. On the riders’ feet are slalom boots and skis as well — short ones, with rigid bindings. The outfit is a dense leather jacket, stretch pants, a hard protective helmet, thick Read more…
Some models of the bicycle electric generator, better known as a “dynamo,” have serious design flaws. For example, the plain bearings in which the rotor shaft rotates need periodic lubrication. And their design is inconvenient to disassemble. Once the lubricant is depleted, increased friction appears, along with wear of the bearing bushings and of the Read more…
The proposed design is a five-section three-seat boat with a carrying capacity of 320 kg. On tourist trips, once hauled ashore, it turns into a fairly spacious “tent,” especially if a piece of polyethylene film is thrown over the top. The boat is so simple that even a person unfamiliar with boatbuilding and having only Read more…
When designing this all-terrain vehicle, amateur designer L. Antokhov from the town of Kirishi in the Ryazan Region aimed to create an all-season, reliable and highly traversable machine with small dimensions and mass, fitted with a closed cabin for three people — a driver and two passengers. The result of the work was an ATV Read more…
that we invite you to build are quite safe and stable, despite having a single runner. The basis of the design is a spruce or pine board measuring 40X300X650 mm. It is even better to take several boards 30—35 mm thick, joint them to each other and glue them together, applying plywood cheeks (4—6 mm Read more…
In one of the episodes of the Central Television program “You Can Do It” (“Eto vy mozhete”), viewers met the amateur designer Oleg Andreevich Ostapenko. We have already grown used to the fact that “EVM” introduces us to people whose technical creativity invariably arouses interest and surprises us with unexpected solutions to various design problems.

If your radio-controlled or control-line model has a non-removable landing gear or its size does not allow a hand launch, don’t be upset by the lack of a suitable runway nearby. A drag sled will help — it can be used both in winter and in summer. To make such “skis,” you will need a Read more…
When building small-scale sailing ship models, a great deal of work goes into making realistic chain plates. I use a simplified method of imitating these parts and fittings entirely from a single piece of metal. Using a special forming jig makes it possible to achieve good results both in accuracy and in appearance. At a Read more…
