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”).
“Shoemaker without shoes” — this old Russian proverb current to this day.

You never tried to bend metal sections “area” or “channel”? If you had, then you probably know how hard it is, especially if the profile is lengthy. Simple drawing mill, made by me, allows you to run a variety of shaped metal profiles with a thickness up to one millimeter in almost any length. In the case are plastic and metals 3 steel grades and the stainless steel, aluminum alloys and brass.
Paper is the most affordable and “compliant” material for the manufacture of all kinds of toys — from boats-boats and pigeons until such unexpected figures as a jumping frog, about which we want to telling detail: how it is folded from a sheet of paper and through which it becomes movable.
In the manufacture of printed circuit boards have to drill a lot of holes. This is best done on a drill press. But many radio Amateurs it is? But it is not so difficult to do.
In the manufacture of personal watercraft, hidrocaribe and other small-tonnage vessels to protect the surface from moisture and make the case the mechanical strength is widely used fiberglass. However, faced with the complexity of the processing surfaces having a large area (an average of about 8 m2). In this rational use of mechanized tools (electric drill, grinding machine, type “Electra” etc.).
The diversity of forms imparted to the curved legs of furniture can be applied to various modern types of furniture, and not just on the products vintage style. While the home worker is the most attractive is a simple model notched legs homemade furniture offered by the French magazine “System D”.

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.
