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…
Ordinary hand rakes for hay collection are an ancient tool familiar to every rural resident. As a rule, all parts of this tool are made of wood to make it lighter—after all, you have to hold it almost always in the air during work. The width of hand rake capture is small, and accordingly, productivity Read more…
The first homemade motorized helper appeared in our family almost 20 years ago. We built it according to V. Ilyichev’s design, published in one of the issues of the “Modelist-Konstruktor” magazine. And we were convinced how good it is to have a universal motoblock in the household, which won’t let you down in any task, Read more…
Bolts, nuts, washers, cotter pins, and other small items are necessary in any household. Or, say, jars and bottles with spices, seeds, chemical reagents… It’s good when all of this is not in “working disorder,” but at hand, in a homemade glass storage rack, the square cells of which are quite capacious and compact. The Read more…
The proposed mini-farm is designed for breeding and keeping rabbits of any breed in both private and public subsidiary farms. Its basis is a two-tier cage-module (if necessary, there can be several of them, united by a common roof). The farm’s design and maintenance regime are thought out so that it can be used even Read more…
The proposed plow originated, one might say, from a shovel. One spring day on my garden plot, I was making furrows for planting root crops. The soil had been previously plowed, but I had to work bent low, and therefore suffered quite a bit. In the yard at that time, my first-grader grandson Igor was Read more…
In recent years, foam catamarans have begun appearing on the water bodies of the Urals. They are unsinkable, convenient to operate, durable, and simple to manufacture. The figure shows the design of such a catamaran. Its dimensions: 3750X1600 mm, plate thickness from 40 to 150 mm, float height 200 mm and width 400 mm. The Read more…
This wheelbarrow was designed (if you can call it that—the process of thinking through the design and estimating dimensions) and built in a few hours after my brother and I received a message from our father in the village asking us to help him build an access road to the house. It was clear that Read more…
“Potatoes are often called the second bread. But this bread is not easy to come by. Especially without using prohibitively expensive tillers and mini-tractors, relying only on a shovel and a hoe. About a year ago, “Modelist-Konstruktor” decided to help, publishing a good development about a tracer-potato planter made from water and gas pipes. But Read more…
Many youth technical clubs and stations (КЮТ and СЮТ) have karting sections. The small machine not only helps kids learn the general concept of how a car works and master the basics of driving, but also paves the way for many of them into big-time motorsports and reveals their potential in technical creativity. The karting Read more…
