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…
Maneuverable, compact vehicles are vital, especially in snow-covered and forested areas. In some countries, such as the USA, Canada, and Japan, this problem is solved by producing compact machines like snowmobiles. Our industry has also started producing such equipment: snowmobiles “Buran”, “Amurets” and others have appeared. However, these machines are more for recreation; they don’t Read more…
Many readers, after the editorial board asked them what amateur constructions (for water, land, and air) they were interested in, sent hundreds of letters to the editorial office requesting the publication of drawings and a description of a light foldable boat for amateur fishermen, tourists traveling on blue roads, for all those who love nature Read more…
