The bicycle is probably the most widespread means of transport. And there is no doubt that it is also the most economical: two buttered sandwiches are enough to pedal for two hours. But can the efficiency of the human “engine” be increased? Reducing “fuel” consumption will not help. Friction and the weight of the machine Read more…
It would seem that driving a nail is about as simple as it gets. Still, even this seemingly straightforward operation requires a calculated approach and some experience. 1. Long nails are best driven with a 400—500 g hammer, and small ones with a hammer weighing up to 250 g. 2. To find nails driven deep Read more…
I offer home craftsmen (and not only them) a tool for welding plastics. However, it can also be used for a wide range of technical creativity tasks — for example, to blow solder off dismantled electronic boards. After all, the temperature of the air coming out of the nozzle tube will reach 300°C, and it Read more…
On his own land, the owner erected a two-storey shell of a “Canadian” house on a strip foundation. The adjacent plot had long been for sale. At last it found a new owner, who invited a surveyor for an accurate layout of the plot. During that procedure it turned out that the neighbour had built Read more…
We continue to introduce our readers — owners of garden and country plots — to nontraditional designs of cottage furniture published in the Polish magazine “Zrób sam”. SWING CHAIR There is probably no one who does not like a swing. However, while a rope and a piece of board are quite enough for children’s swings, Read more…
If you recall that cross-country racing skis are designed mainly for travel on a prepared track, while wide hunting skis handle any snow, it becomes clear how the proposed homemade sled design differs substantially from store-bought ones: above all, it does not require packed snow slopes. Even the fairly popular three-ski snow scooters “Chuck and Read more…
Improving drive efficiency is a problem that concerns not only bicycle designers, but also the owners of these machines. Since the invention of the bicycle, the pedal drive has been brought, one might say, to perfection. Increasing its efficiency without complicating the mechanism is hardly possible. On sports and touring bicycles, for example, multi-speed transmissions Read more…
The times of treasure hunters are back. “Black” and “green” searchers look for artifacts of past eras, dedicating all their free time to this pursuit. All in the hope of finding a coin hoard or a weapons cache. One cannot condemn them — times are hard. Better, if possible, to help. One of the main Read more…
When furnishing a country house — whether a small garden cottage or a solidly built dacha — many people bring there the furniture that has outlived its usefulness in a city apartment. And most often this makes the whole setting mismatched, bulky, and at odds with the idea of a place for rest. Meanwhile, it Read more…
This machine can indeed be made from an old table, and it really is a whole workshop: our reader, engineer B. Popov, who built it, provided for interchangeable working tools — here you will find a circular saw (1), a grinding stone (4), a planer rotor (3), and even a lathe setup (2). Replacing hand Read more…
