Concrete drill: slot for fast hole drilling

In one of the issues of previous years, your magazine published a note — “Again — a dowel”. It should be said that the suggested versions of a metal combined dowel are rather complex to manufacture, but their use is justified for hollow panels and shield partitions, which in modern new builds are not that Read more…

Grinder made from a drill

DIY Flexible Rotary Drill: universal tool

I’ll probably be right in saying that most home hobbyists dream of having a universal rotary tool at their disposal. How many opportunities it opens for its owner! Engraving, abrasive machining of parts with complex shapes, making stamps and press forms yourself, drilling and countersinking holes located in places hard to reach with a regular Read more…

Tabletop saw

Combined Tabletop Circular Saw for a Model Club

A combined tabletop circular saw is needed by every model-makers’ club. It makes it easier to carry out a whole range of woodworking tasks; in addition, by replacing the tool on the bench, you can sand wooden parts, polish metal surfaces, and sharpen tools. To make such a machine, you need a single-phase electric motor Read more…

Snowkart for sports and recreation

Snowkart with T-200 engine: wheel-ski build guide

During the winter season, motor-sport enthusiasts experience a period of relative calm. The reason is the poor conditions in which the rider finds himself: once he rides his two-wheeled “friend” onto a snow-covered road, sometimes with ice patches. And off-road you can go only on a specially prepared motorcycle (with studded tires). Using the idea Read more…

Pedal surfer

Rowing attachment for a windsurfer with a pedal drive

A windsurfer, like any sailboat, needs wind. Meanwhile, on its hull-float it is possible to swim even in calm weather if necessary. In the magazine “Modelist-Konstruktor” there was once a mention of using the hull in a rowing version — with a two-blade kayak oar, or with an ordinary pair of oars (though in the Read more…

Drill in a harness

Self-propelled plow with an electric drill: winch

With a fairly powerful compact drive, the electric drill has long become one of the leaders of household tools. And with attachments and all kinds of fixtures, it is quite happy to get ahead in agricultural work: it already mows, threshes, and performs other operations excellently. It becomes a true universal tool! Moreover, thanks to Read more…

Bee house

Cassette Beehive: Construction, Assembly and Care

Today we introduce readers to two such works, interesting above all because they address an area of home farming that is still only weakly covered by technical creativity: beekeeping. For it, club members of the Palace of Pioneers and Schoolchildren of the Bauman District in Moscow have created a very convenient original hive for use, Read more…

Micro motorcarts

Micromotosleds with the D-4 engine: design

Before introducing the material below, we’d like to recall a short note in issue No. 2 of our journal for 1979 — “Folding sleds.” The reason is that the author of both designs is the same — our reader from Kazan, E. Zakharov. His technical creativity was prompted by a little son who every morning Read more…

Fetching firewood with a chainsaw

Motonarts from a “Ural” chainsaw: DIY snow scooter

Winter in our northern parts is long. There aren’t many roads, and even those don’t manage to clear snow in time. That’s why it’s hard for people here to get by without snowmobile machines, especially when you often have to ride completely off-road (for example, into the forest for firewood) — right across piled-up snowdrifts.
