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…
Few car owners do not try to improve their consumer qualities. The most extensive field of activity for auto-rationalizers is the power plant. From time to time, publications appear about gaskets, attachments, or additives that increase engine life, optimize fuel consumption, reduce exhaust toxicity… Our Ukrainian reader proposes an aerodynamic attachment for the carburetor. He Read more…
Every DIY enthusiast regularly faces cutting sheet metal and non-metallic materials. Using hand shears is inefficient (especially for large sheets): with high labor costs, the cutting quality leaves much to be desired. At one time, I used factory-made lever shears for metal. However, unfortunately, they had a not very reliable design, and when trying to Read more…
To obtain hot water in a bathhouse, a tank-register on the stove pipe (or a boiler in the stove itself) and an external tank in the washroom are often used. Water circulation between them is carried out by natural convection due to the difference in specific weight of hot and cold liquid at temperature differences. Read more…
I am a long-time, or rather, hereditary subscriber to the magazine “Modelist-Konstruktor”. At first (since 1972), my father – Galkin Grigory Petrovich (he is now 80 years old) – subscribed to the magazine, and then I did myself. Since the beginning of the “Aviatscollection” supplement, I have been subscribing to it as well. As long Read more…
Many city dwellers would like to take a steam bath in their own sauna, but in most cases they don’t have such an opportunity. Even owners of dacha and garden plots don’t always have the conditions to build a full-fledged bathhouse: one lacks space, another lacks funds, a third lacks both. I considered myself one Read more…
The proposed machine is designed mainly for recycling dilapidated wooden structures into firewood. Due to the many nails sticking out everywhere, this waste material is beyond the capabilities of the “Druzhba” chainsaw, and therefore costs mere pennies. The cheapness, of course, is attractive. What stops you is something else: what and how to cut such Read more…
For more than a year, Stepan Ivanovich Gorshkov has been perfecting the bicycle design. His efforts, however, are not aimed at achieving high speeds. No! Let the racers do that! Comfortable seating while riding, easy transportation on trains — that’s what his efforts are aimed at. The main principle of all improvements by S. I. Read more…
Imagine this: you’re standing on the shore of Ecuador’s Lake San Pablo, with a view of the dormant Imbabura volcano before you, and parked nearby is… no, not a luxurious camper with panoramic windows and a rooftop hot tub. Next to you stands an ordinary Chevrolet Super Carry—the same van you’ve seen a thousand times Read more…
When setting off on a long journey, a skier typically relies only on their own strength. However, it’s quite possible to call on the wind for help by building a sailing tug for this purpose. Assembling such a tug is quite simple, using rigging from a sailboard — a mast, wishbone boom, and sail with Read more…
