In the practice of the rally often faced with the necessity of soldering or welding. A few years ago I accidentally saw used for this purpose, benzopyrene production of the GDR, then had the idea to do the same, but running on gas. The result exceeded all expectations — and now gas-heated soldering iron is a decent place to set my tools. Exploitation it during body repairs, radiators, bits of copper cables with large cross sections confirmed the efficiency of the design. The main advantages before traditional “hammer” and a blowtorch are: the possibility of continuous soldering, the temperature setpoint, which is important when performing large volume of work, as well as the possibility of regulating the degree of heating.
GAS SOLDERING IRON
Once television was a popular program “you can”, where the craftsmen talked about their designs. Perhaps it first appeared the information about the pneumatic-tired machines. A publication in the journal “modelist-Konstruktor” has prompted many enthusiasts, including our own, Angarskaya (mostly fishermen) to manufacture such machines with their own hands. Pneumatic bribed his external simplicity, which promises a good performance. 
Wags say that invention, they say, are born from laziness. Maybe they’re right. I tired to cut the tops and chop the root vegetables for domestic animals manually — set about creating an electric shredder feed. Memory told where to find the prototype: of course, among the developments of the journal “modelist-Konstruktor”. Indeed, the number 12 in 1992 found a description and sketch Assembly “lubarsky for cows”. But the cone-shaped cups from the separator, which served as the basis of the unit in my possession was not. But there was a sheet of the stainless steel. Made from it a cylindrical “bucket”, which became the shredder feed. And the bottom are made with a flare — for a better connection with the side wall (welding face) and increase the stiffness of the whole structure.
Accurately process small parcel of land on which “serious” technology closely, except that the tillers. Therefore, the prudent farmers, deciding to get a similar unit, first choose the make and weigh its capabilities. And then think about the truck, mounted and trailed equipment that will be needed for your specific job. So was the case with me. The only difference is that I decided not to buy ready-made tillers, and build it yourself. For the sample took the industrial design “the meadow”, Podkopayeva its simplicity. But only a sample because I have assemblies and parts which are markedly different from standing on the prototype. They had to fit, and many components and parts — manufactured again.
Less and less will see on our roads a nimble scooter. This is not surprising: the main producers and their fates were abroad — in Latvia and Ukraine. So what else from this series is now sold in specialized stores, is cars. Accordingly, the price… To all that volatile MOTOmed gives the consumer a more convenient, more modern cars of the same class — scooters. Miniature scooters with 50-CC engine with automatic transmission and starter, can reach speed up to 80 km/h, providing comfort, who never dreamed of the owner of “Riga” or “Carpathian”.
