Even the person far from technicians, often have to Unscrew-screw the screws, bolts, nuts (hardware — so often referred to in abbreviated form these metal products) are designed for this tool — a wrench. Each key caused the size of its working parts, simply — throat. But the corresponding value is the size of the key — referred to in the technical handbooks by the letter S (the distance between the opposite parallel faces on a nut, bolt head or screw), is not listed on any of the fasteners. No, as a rule, these data and the attached to any technology operating instructions and repair even in the notation and in the drawings, although other information about fasteners in them abound: specify thread size, and her step sometimes the length and even the type of heat treatment, often tightening torque. But most of these data — structural, and they need to manufacture parts. When the adjustment, repair or Assembly work of the above settings thread, except the last one are not in demand. For a mechanic it is much more important to know what size front axle you need a key for the head of one or the other of the screw or bolt and nut (or, as professionals say, “the key is how much”).
THE KEY IS “HOW MUCH”?
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. On the pushrod and is an ill-fated piece is a small rubber ring that provides a reliable seal between the follower and the walls of the sleeve.
The aircraft belongs to those fields of technology which are developing particularly rapidly. In a historically short period of time, speed, altitude, payload, flight range of the aircraft has increased several times.
In the literature on model airplanes is not so much focus on radio-controlled models of seaplanes, although, in practice, many enthusiasts prefer them purely “land”, considering the “waterfowl” more interesting for manufacturing and piloting. Many of them also refer to the usability of such models compared to those that are equipped with wheel chassis, because “land” is not everywhere possible to find a large enough area with asphalt or concrete path for takeoff and landing. While any aquadrome — a pond, lake or river to find not so difficult. In addition, experts argue that take-off and landing in the water are not in the example easier.
Instead of installing switches ship modelers often put on the deck bare conductors or put the bulky switches. Naturally, these alien items spoil the appearance of the model. At the station of young technicians of the city of Sochi for many years put on an improvised model of the microswitches (see figure), Tali. Then put the spring and install the bracket-holder. The deck clip is fastened with copper rivets. The switch is ready. Connecting the wires, you can test the reliability of his work.
It is the lack of any drills often drill in the Chuck begins to rotate, especially when exiting from the drilled hole. And in electric drill drill bit you can still firmly hold a special knob in the manual is not easy to do. Therefore, readers will probably be interested in a little improvement which I have used for a clamping Chuck of the tool. The hall hand microdrile screw a regular nut (key 19) and secured it on the threaded pin M4, and on the cartridge with a handsaw and made two flats on turnkey 22. This upgrade allowed two wrenches to firmly secure the drill bit.
The creation of the original screen is of considerable importance in the design of light and music. Svetoteni fall primarily into two types with distinct colors and gammopathies — there takes place a combination of colors.
Where a person lives, there’s a crow look is not necessary — it is everywhere, including near our garden plots Ravens fly around, sit on a high place, the roof and, looking out edible, never miss a chance to steal something that is bad Gardeners have made peace with that and didn’t pay much attention to either the Raven or their cawing.
Post-war industrial crisis has forced automakers in many countries to pay attention to cheap minicar — just like she had at the time a steady demand. Was no exception to this process and firms of West Germany — in the automotive market of the country had at that time a lot of sidecars — a four-wheeled Heinkel Kabine and a Zundapp Janus, a three-wheeled Messerschmitt and finally, the BMW Isetta with the rear wheels close together.
