In last year’s fourth issue of the journal, I read an article about Razakhatskaya V. the machine “Skillful hands”. There is proposed a device for drilling. But it will have to cut off part of the shaft, and the remaining grind down under the cone, which excludes the possibility to use other devices.
Asphalt streets of towns and villages, even distant ribbon of highways — all of them like a layer cake, if you look in the context of: roadbed, sand cushion, bed concrete, asphalt. Each day of the five-year plan adds to existing roads new kilometers. And builders have a special road test: how firmly Packed surface, is it willing to stand under the infinite load of the modern transportation?
With the development of industrial building methods became widely used details of full factory readiness. However, there still remains an urgent problem mechanization of plastering and grouting works for the walls and ceilings of buildings, and especially in rural construction.
No, it will, of course, is not about the equipment of the dental office on a production site. However… picture this: a dentist, firmly gripping with two hands the body of the machine with the motor inside, trying to get to the tooth of the patient a thin boron fixed in the Chuck mounted directly on the motor shaft. Inconceivable, right! Everyone knows that the engine and boron spaced and connected to a long flexible shaft: hand of the doctor easy and comfortable to hold thin tip of the working head.
What would be a good tool or even the machine had craftsman in the house, just drill a hole or accurately process the workpiece by holding it with pliers, and even more in the hands of, quite frankly — impossible. Therefore, in the Arsenal of anyone, even a beginner DIY enthusiast, there is Vice. However, and this adaptation is not always thus, what is required, especially when high dimensional accuracy of the parts, strict parallel, or perpendicular to its surfaces, etc., etc.
To the two parts worked as a whole — they should be connected to. Where possible, use bonding, soldering or welding, but all these options are permanent fixtures. And here is the bolt to nut connection is universal: he is subject to any material, and if necessary disconnect them tight elements of the design — this fixture is easy to Unscrew. However, such a connection provides the necessary resistance only when the bonded parts are inactive; and in the event of impact, for example, vibration can fail because of such insidious phenomena as samothracian.
A variety of roller chain, like a Bicycle or a motorcycle, are used on many machines, including most agricultural units. With their Assembly during the repair of machines of great assistance can provide a simple tool offered by pioneer A. Yurchenko (see figure).

In most cases, the part is placed on the machine perpendicular to the processing tool. A simple device created by Odessa innovator, Tandit, provides a fast and secure workpiece at any angle with an accuracy of 1°.
Measure the bore diameter or roller to determine the size of the gap with an accuracy of 0.1 mm it is possible not only with the help of micrometer, Vernier caliper or feeler gauge. Each of the offered here for measuring instruments easy to make at home in just one hour.
