It’s safe to say there is not a single sector of the economy of our country, where would be a creative contribution to the implementation of the decisions of the XXV Congress of the party, the tasks of the five-year plan Komsomol members and youth. Tens of thousands of engineering developments of young enthusiasts of technical creativity, innovators and inventors, is introduced in industry, agriculture, construction and transport, contribute to the acceleration of scientific and technological progress, the early implementation of the plan. The best of them were presented at the Central exhibition NTTM-80 in Moscow.

Equipped lover of winter fishing among other people, it is easy to distinguish by special box-seat, which many call a modern wardrobe trunk. Because angler-“podsednik” without a box, like a tourist without a backpack, like a mushroom without the boxfish as a hunter without yet feels. But because each of them seeks to acquire such equipment.
The functions of the boring machine can run, and milling. Of course, at a lower level of precision, but for many works this is not essential. For such conversion we recommend you to use developed in Valuyskiy young technicians universal boring head: it impresses manufacturability and simplicity.
Draw the circuit diagram, weathering adopted the proportionality of graphic symbols electronic elements, it is not as simple as it might seem at first. Great help here can have a stencil plate of thin transparent material with holes and slots corresponding in form to symbols of parts adopted in the Unified system for design documentation (ESKD). This stencil need not only for Amateurs but also professionals working in this field of technology.
Versatility — the main advantage I have developed multi-operational machine for working wood. Him “on the shoulder” turning, pugovka, cutting the material, drilling, milling, tenoning operations. In the end, it is possible to sharpen a tool or make it into a joiner’s workbench.
Perhaps it can be called the first and most accessible for a child flying a model made with their own hands. And really to make a paper dove will not require any tool or special materials — just take the conventional typewritten sheet and some times it is to bend. Here’s how the baby should be show at least once: the second time he will easily repeat these simple steps for himself. When the child firmly mastered the original version — he wants the dove to fly better. And then let him in on a little secret.
On the ridge of the roof of the house I made a weather vane Carlson. The design is very simple to manufacture. The “Carlson” produced from a metal sheet thickness of 2 mm. the Figure and the rod from the rod Ø8 — 10 mm rigidly riveted together. As the rotation unit used the wheel hub of a Bicycle wheel with bearings. Below is rigidly secured large fishing bells (indicated on sketch). The same bell in hand “Carlson”. From the natural vibration during the rotation of the propeller and in the wind all the bells are ringing.
Usually on the surface of stored paint forms a film or crust, when removed often remain in the container its particles: once on the brush, they can spoil the work. Take the time to look for an opportunity to drain the contents of the can. Please cover it with a piece of rare fabric, for example, old nylon stocking, and a little indentation its the same brush: the paint will show through an improvised sieve and be pure as strained.
