We read with great interest in the magazine the descriptions of the hydro-sleds “Pioneer”, “Dolphin” and “Pirate”. We should note that on the waters of the Ob Sea, such vessels can be seen every summer. These are “Typhoons”, the drawings of which were developed in the experimental mechanics laboratory of our KUT. Undoubtedly, the new Read more…
Musician D.T. KUDRYACHKOV is known among amateur constructors as the author of the unique amphibious car «Triton» — the only vehicle of its kind registered simultaneously with two state inspections: automotive (traffic police) and small vessels (GIMS). Our regular readers may recall the publication «Gliding… car» («Modelist-Konstruktor» No. 5, 1996), which contained a fairly complete Read more…
I live in Krasnoyarsk Krai. I have my own house and a small garden plot. Every spring, while digging the vegetable garden, I thought about how to ease — mechanize — this laborious work. So I decided to build a motorized plow. I had an engine — from a motorized bicycle. I made the frame Read more…
Rust is enemy number one of almost any metal. The “red plague” that with enviable persistence and constancy turns hundreds of thousands of tons of sparkling high-grade, high-strength, alloyed steel into heaps of brown powder. A disease for which there are no barriers… But there are remedies for it: galvanic coatings, varnishes and paints, bitumens Read more…
To avoid running extra wiring for auxiliary electrical appliances when using a portable lamp, it is enough to fit a homemade adapter into the lamp holder, as shown in the figure. To make the adapter, use a lighting socket in which three holes are drilled: one in the base—for the cleaned (glass and glue removed) Read more…
I read in the magazine «Modelist-Konstruktor» No. 12, 1992, A. Tatarnikov’s article «Obedient trailer». It suggested a solution to what at first glance seems a rather ordinary, but on closer look almost unsolvable problem: how to fit a motorcycle with a sidecar with a trailer that would follow it track-for-track? The idea of building a Read more…
A concrete mixer is constantly needed when building a house. A lot of cement mortar is required, and it also needs periodic mixing. A tub with a shovel are poor helpers here — you’ll tire yourself out to the point of aching all over, and the mix quality will still be low. Buying a branded, Read more…
Portable electronic devices with low-voltage power supply are often designed for batteries and accumulators. Among such devices, the most popular are electromechanical and digital clocks, radio receivers, flashlights, and… wireless doorbells operating on a radio channel at a frequency of 303 MHz (there are variants at 933.25 MHz). Digital cameras with a connector for external Read more…
When building amateur aerosleds, gliders and hovercraft, the greatest difficulty is usually choosing the right engine. Standard production engines often fail to satisfy home‑builders in many respects, particularly in terms of specific power. The most radical way to solve this problem is to build homemade engines using parts from serial motorcycle engines. Readers of “M‑K” Read more…
If a country house or rural home has a high roof — it’s a sin not to take advantage of such an advantage and not to arrange an attic there: it can serve as an additional bedroom, study, and even a children’s room. The under-roof space itself can be equipped both during construction and in Read more…
