One of the most critical components of the machines crawler — tanks, all-terrain vehicles, armored personnel carriers, tractors, trucks is the suspension, particularly caterpillars. Their tapes, as you know, is assembled from separate parts — the tracks connected by fingers. Each track has a grooved surface — lugs deliver reliable traction. On the side of the track facing the rollers, is guide comb, preventing a descent of rollers with treadmill tracks the motion of the model, especially during turns.
We offer proven our ship mug method: to make propellers with electric current from foam. Simple device allows you to quickly produce a series of identical screws, which in appearance is no different from bronze, but do not sink in water.
the Conversation today will focus on the sailboat of a new type — light weight, affordable and versatile vessel-trimaran, which portable travel paddle with a soft shell. The merits of such a lot of trimarans, and one of the most important is the low cost of the kayaks and additional sailing arms.

All control systems work quickly and reliably, and steering is effective in any maneuver.
It was called hydrocardon, although it is more like a kind of water motorcycle. Built is sports microsode the Donetsk regional station of young technicians in the circle of “Small shipbuilding.” As reported in the editorial of the Director of the station N. Vladimir Vasilyev, the club celebrates this year its fifteenth anniversary. Initially, in the classroom young engineers studied the structure and purpose of a variety of sports and pleasure craft, have developed a new design .mostly motor boats. The work aroused great interest guys, but I felt that something still was missing. It soon became clear that the young “shipbuilders” I wanted not only to create a motor court, but also to experience them and more — to compete: whose machine was faster, so, technically perfect.
