Interest in homemade mufflers is driven primarily by the unsatisfactory quality of series products. It is quite natural for an amateur designer to want to improve the parameters of their vehicle. Of course, it is practically impossible to significantly increase engine power through a muffler at a given exhaust noise level, but eliminating some shortcomings Read more…
I have subscribed to the “Modelist-Konstruktor” magazine since 1985 and have never regretted it. I read everything: from the first page to the last. It is a very useful and interesting publication. And although times are hard now and the magazine is not exactly cheap, I will continue to subscribe, because I believe the value Read more…
For my first walk-behind tractor, I used the Vyatich as a basis; its technical description and sketches of its main assemblies and parts had been published in Modelist-Konstruktor magazine. However, my capabilities and material and production resources differed from those available to the designer of the Vyatich. The result was a homemade machine that bore Read more…
A filter is an important device that helps clean the water in an aquarium and, at the same time, saturate it with oxygen. Water is passed through the filter by means of a system of communicating vessels, and the motive force for pumping water from the bottom of the filter into the aquarium is created Read more…
The favorite car in the countryside is, without doubt, the full-wheel-drive, high-clearance VAZ 2121 “Niva”. Unfortunately, our industry does not produce trailers specifically for this model that have a high load capacity and can be operated off-road. And that’s a pity! Rural residents have an enormous need for them: they have to haul building materials Read more…
The quiet of a sunny spring morning was broken by the throb of an engine. A villager digging his garden with a spade straightened up and looked over the fence at the neighbor’s plot: what was that noise at the Ilyichyovs’ place? He saw a small two-wheeled machine emerge from behind the outbuilding into the Read more…
A car’s handling and tire wear, as is well known, depend primarily on the condition of the front suspension — the caster angles of the steering axes, as well as the camber and toe angles of the wheels. As a rule, all of these parameters are adjusted on special stands at service stations; however, even Read more…
In “M-K” No. 8, 1984, we wrote about an arched cold frame built by schoolchildren. Its main load-bearing elements — the half-arches — were made from gymnastic hoops. That circumstance strictly determined the size of the cold frame. Yet it is very tempting to build, on the same principle, a more spacious and easier-to-maintain structure Read more…
Over the past decade, motor all-terrain vehicles on light wheels with pneumatic inner tubes have become especially popular among amateur designers. The remarkable cross-country ability of such machines prompted sailing sports enthusiasts to use the unique properties of the pneumatic wheel when creating all-season sail craft. This publication introduces readers to such a vehicle. So, Read more…
Of the family of micro-tractors developed by students at the Kharkiv Institute of Mechanization and Electrification of Agriculture, the simplest and most accessible for DIY construction is the walk-behind tractor “Malysh” (KHIMESKh-2): it makes maximum use of units and parts from industrially produced machinery. This is a compact two-wheeled machine controlled by an operator walking Read more…
