Automotive pump, of course, performance bike, but they (if the pump is to the old bike) unequal valves, which eliminates the possibility of replacement. Small adapter to motor valve will allow you to easily and quickly inflate and voloshino. To do this the old autokamera cut valve, reams the lower end to 4.5 mm at Read more…
The first experimental coaxial helicopter construction.And.Kamov, who headed at that time, the Bureau of new technology of TSAGI, took to the air in 1947. In 1948 N. And.Kamov continued to work as chief designer of the specialized design Bureau. And in 1953 there was built and tested helicopter, which became a turning point for EDO— Ka-15. It was a double unit coaxial with the engine AI-14V power of 255 HP design A. I. Ivchenko.
The seaplane Kawanishi H6K and H8K. On the eve of the Second world war, Japan was among the few countries, which fleet was armed with large multi-engined flying boats ocean class.

In today’s production is no surprise micron precision. Moreover, in the manufacture of many devices, mechanisms required to “catch” a few hundredths of a micron. That’s why in our days precision, or as it is called in the industry, precision manufacturing requires a skilled worker, so he could work on modern machines, able to produce products of the highest accuracy class.
