Spearfishing in waters with complex bottom relief and limited transparency of water has its own characteristics: no time to restore the gun, nowhere to maneuver. Rifle, currently available in the sale, for such conditions uncomfortable. Which is preferable underwater guns. Of the known types of such weapons is most suitable — capsule. Their main advantage is that when fired the harpoon at the impulse of several hundred kilograms, in contrast to the guns of other systems where the force on the harpoon does not exceed tens of kilograms. Accordingly vary the speed of the harpoon. The advantages of cap and ball pistols can be attributed to the ease of loading.UNDERWATER GUNSHOT

That recumbent healthy, I think, nobody will argue. Well, for fans of technical creativity it doubly useful as it allows you to gain invaluable experience before the greater constructions. Recumbent, about which speech will go, was designed and manufactured in the workshop of young technicians (syt) of our city, together with members of the group. I must say that the idea of its creation have arisen much earlier, but because the materials and most of the parts (particularly wheels) have prepared himself, at his own expense.

Large problems sometimes arise because of the small details. Take, for example, the servo-mechanism, reduces the efforts on arms control such a powerful and popular tractors as Chelyabinsk Т100МЗ or T-130. They have the bushing hole (see figure), is pressed into the housing of the servo-mechanism, performs reciprocating movement of the pusher, the transmitting motion of the control lever rotate the spool getorcreatenode site.

How to be autoconstruction mug? What it should build cars? How to organize classes? These and many other questions were raised in the recent publications of M. Larkin, and L. I. F. Rychkova “Project — model — car” and “car Designer — car designer!” (“M-K” № 1, 1979). More of our readers interested in the technical side of things — the device is modular inputs to directly affect. Today we offer the latest development autoconstructor laboratory Cut of the Siberian branch of the USSR Academy of Sciences — the micro-car, only “Protein”.
