A bit of history. I’m 48 years old. Twenty years ago with his younger brother built a sled “Idea-2” — material about him was published in the “Modeller-designer” №11 for the year 1991. Later, when I was Director of Заводоуковскоq station of young technicians under my supervision in her circles were made around 20 such structures with different bike engines of Soviet manufacture. I must admit that the construction of the snowmobile largely contributed to assigning me to this position.
Garden cart with a wide, roomy basket and grates to build sides for a variety of work in the garden, on the plot. However, every one dealing with the earth, primarily digging, is engaged in planting, sowing. The cart is easily adapted to perform these functions: to collect on its basis the processor, combining a number of tech or other operations. Of course, you will get a non-motorized unit that is designed for your own power.
Not always the sheet is bent along the marked line — this applies particularly to small details. The case will help the cutter, sharpened an old saw blade. Along the fold lines, make a small incision on the side where you will have to bend the part. To the strength of the tin not diminished, Read more…
models of gliders classes A1 and A2 must satisfy three requirements — stiffness, strength and low weight. The best results are obtained by the use of tapered thin-walled fiberglass or balsa tubes. But the technology of manufacturing these beams is difficult. Our proposed design is much simpler, the material for it is available to everyone. Despite its simplicity, such a beam is well proven in operation.
In the old days tresses are able to sharpen many, although it is not easy: before you bring the blade up to the ringing of the sharpness of the grindstone, it beat with a special hammer on a rounded anvil. Now, few people know the art of hitting. And it would be necessary. For example, in collective farm “Progress”, sponsored our Cuto, in the time of haymaking on the fringes of the forest and other uncomfortable for the Parking the grass mowed manually. KOs, of course, a lot, and the old man who knows how to discourage them, a few units do not have until the new dawn, the bot came to us farmers to help mechanize the process.
For years, the rubber motor due to its ease of use and low cost were the main engine modelers. But now, with the abundance of micro-motors boat and car with rubber motor find its ardent supporters, as evidenced, in particular, and editorial mail. Among your questions, dear readers, the most frequent two. So T zavgorodnego from Volgograd, E. Shcherbina from Semipalatinsk, A. Zhdanov of Moscow and other interested in how to calculate the number of turns of the rubber motor to maximize its energy, and what is its maximum energy efficiency.
It is hard to imagine the competition without rocketmodeler launches RC models. It is, along with the competitions models-copies, quite an interesting spectacle, including from a sporting point of view. Of course, impressive for the beauty of the start of the model rocket—glider with a rocket motor and control its flight using radio signals.
If you have a “no” trimmer, it will not break the neighbor… So, to paraphrase a famous song, you can start the story about the problems with manual lawn electromobility. Most of the models imported electrochimprom (from the English word trim — cutting, trimming) is clearly not designed for the Russian kolodong mowing lawns or weeds around fences.
The word “cultivator” has entered our lexicon relatively recently. In principle it is the same tractor only built on the basis of single-axle chassis and designed to actuate a replaceable mounted and trailed agricultural implements, and controlled by the levers behind the operator. In some cases, when the walk-behind articulated to the truck, he becomes the vehicle and the operator does not go and goes.
In the GDR skiing designed the lift with a drum on which is wound a pull cable. To do the same, you will need a moped engine with a working volume of 50 cm3, its exhaust transmission from the motor car, homemade rope drum and band brake to it.
