Remember PushPull fabulous animal which could jump not only forward but also backward, because instead of a tail he had a second head? About it can not help reminiscent of the original bilateral cutter, manufactured by the innovators of the Gorky machine-tool production Association. Tool on a conventional tool holder has two cutting inserts mounted on carbide lining and is mounted to the top clamps. Under the clamps located struzhkolomy.
During the Second world war, Germany was the leader in the development of heavy armored vehicles with wheel formula 8×8. After a good armored car Sd.Kfz.231(8 Rad), which was a frame structure, followed by Sd.Kfz. 234/1 with a monocoque body (see “armor collection” № 1, 2007). For these machines and their modifications was characterized by the presence of all eight of the steered wheels and two control stations. Four-axle, or, as they are often called, vosmiklasnica armored vehicles have been successfully used by Hitler’s Wehrmacht in all theaters of war until the last days of the Second world war.
There is no need to secure the dowel in the hole in the wall, screwed it in the screw firmly rasclient it there. Is it possible to use this principle in the connection of wooden parts using wooden studs? It turns out that you can. For this spike it is necessary to saw through the Read more…
If the amount of grinding work to be done is large, it is advisable to make a simple tool holder under the sandpaper: work will become much easier and more comfortable. The wooden bar are two oblique transverse cut, in which are inserted the ends of the skins. And in order that they don’t pop Read more…
Rationalization proposal Lyubertsy student of secondary school № 42 of Konstantin Shishkin. If you need to turn on a lathe a few identical parts rather complicated configuration, it makes sense to use a universal strap-holder which can be mounted a set of cutters. It is made very simply is a steel bar with a groove Read more…
Adjusting the temperature of the local heating using the original heating element. The idea of local heating of a small area is implemented with the help of available details that it will probably in the reserves prudent owner, including, of course, owned and hams. Moreover, as the heating element applied to ordinary fixed resistor with a power dissipation of 2 watts. Depending on the power and resistance of the constant resistor can be achieved heating limited site to a temperature of -40 °C or even 60 °C.
Design domestic car GAZ-21 “Volga” is haunted by the many fans of this car. Some create precise scale models-copies of this iconic sedan. Others meticulously and carefully recreate the published in the edition of luxury vintage cars, which today look better than the ones that came off the Assembly line 50 years ago. Well, while others using a fundamental design decision, so happily found in the design of GAZ-21, creating the “explanation” of this car an exclusive design.
In recent years, rakotomalala all levels are fond of a simple “building” material for flying model — plain paper. The journal “Modelist-designer” told you about the paper models on their pages. And if earlier to make the model only of paper required regulations, today this material is widely used “voluntarily”. The proof starts at the all-Russia competitions on the Cup of S. P. Korolev. About 40% of the participants in the classes SA and Ѕ6А used the paper model. Our story about the rocket champion in the class of parachute models (SA) Denis Gaganov (Sergiev Posad).
From circular knives, no matter where they worked in agricultural units, in the fields or in industrial plants, — wear out really fast sharp working edge. Therefore, innovators tend to find the most effective method of restoring the load of the tool.
Have trace modeling particularly attractive trait: despite the relative simplicity of the models, they give space for the creative work of the children’s thoughts, development of design imagination. An illustration of this situation can serve as our mug on the car model “Stratos” (Fig. 1). Recently Moscow plant “Young technician” started to produce the engine of DP-15. He has two obvious advantages: its capacity is sufficient to move the model, and it is quite affordable. Another plus: when calculating gear, you can focus on the spur gear for electric shavers that are sold as a spare . parts. Cons — size and weight — when novice modelers can not be ignored.
