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”).
Heat the water to 50-60° can setting developed by the participants NTTM special design Bureau No. 1 of the Institute of power engineering Institute imeni G. M. Krzhizhanovskogo. Interestingly, there is no furnace or heaters. Replaces them… the sun. This setup is especially desirable in those areas of the country where local fuel is missing, and the cost of imported quite high.
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.

When connecting parts of the piping or hydraulic system, connect the tool to the pneumatic system or an irrigation hose at the joints not to do without special connector — threaded couplings, a special cartridge or fitting.

Along with the usual flowerbeds and green lawns are increasingly lined with durable, beautiful tile paths, erecting ornamental fence and wall, comfortable Lounges with sun-gazebo-pergola and relevant fittings, arrange a miniature pools.
Yes, on any lathe with a hollow spindle it is possible navit spring diameter up to 12 mm from the wire thickness of 0.1 to 2 mm. More than that — of any length. All this is provided by a simple device introduced by NTTM participants at the Leningrad order of the red banner of Labour plant of lifting and transportation equipment named after S. M. Kirov. Unlike similar devices, there’s a knot in the wire feeding thanks to the ingenious solution available for self-production in rural workshops.
In the household of great assistance can have a miniature electric drill. Easy to make on the basis of the motor WCT-1, is designed for EPA of the store and radios (see figure). The cartridge is made of steel round or hex bar. In the center of the drill a through hole Ø1—2 mm (depending on drill diameter).
The kids, happily folding cubes and collecting of the pyramid, and did not suspect that this so-called educational games designed to develop quickness and coordination.
