The idea is to expand the capabilities of the lathe for matches, published in the journal “modelist-Konstruktor”, arose when it became clear that, first, wood is modern matches absolutely unsuitable for such work and, secondly, the size of matchbox blanks severely limit the choice of machined parts. As a result, fixing of workpieces on the motor shaft nipple rubber require replacement.
Since ancient times it was believed that one who follows the advice of an old Russian proverb: prepare sleighs in summer, and in winter the cart” without any doubt, can be considered a good, zealous master. Carried away almost ten years Cycling, I have always been fixing his “iron horse” and a complete set his spare parts in the winter.

if you increase the intensity of the heating installation in free areas of heating pipes for additional plates-clamps made of heat conductive material (e.g., duralumin), as shown on the drawings. I. PICHUGIN, Orenburg
Recently an increased interest among readers judging by the letters and calls to the editor, raise questions related to the bench scale models. It is caused, apparently, the increasing penetration of imported models to the Russian market. Hence the request to the editor: to tell you about a common, global scale bench models.
In the yard, on a personal part, in the country there is often a need for reliable stand — for example, for tensioning the rope when sosne linen.

What will you do if the sink burst the plastic nut connecting the trap with the exhaust pipe or a sink, and a new one in the store to buy failed? From the tan situation, I came, putting on the threaded portion of the siphon segments of Cycling cells measuring approximately 60 mm, and the Read more…
As is known, operation at a higher supply voltage, the mode transition processes (with frequent switching on and off) are light bulbs guidelinesin follows: ultimately burns out the filament. Meanwhile, the lifespan of light bulbs can be considerably increased if you connect them to the AC mains via a special adapter, each of which — your… rectifier. Of course, compact: solid-state, half-wave rectified without filter.
If you use as “inflatable fuel tanks cuts rubber catheters are recommended… not to throw away spent cartridges from under aerosol mixtures. The fact that after cutting of the cylinder is possible without damage to remove from the mounts the valve with the housing. And the valve is the ideal adapter for the production of “inflatable” tank. From the larger diameter valve has a shoulder, as if
the Stopper of a thermos under prolonged exposure to high temperatures over time, weakens and poorly kept in the neck of the vessel. A reliable lock can provide a strong thread or thin twine, if you skip through them made the top slot, so that the ends hung down to the threads on the body Read more…
Perhaps you will agree, that more accessible and useful for the health of stadiums than small and large rivers, lakes and reservoirs, and a large number are scattered all over the country, it is difficult to come up with. But today, they, unfortunately, are mostly deserted. In recent years, water a bit back from the sails of the windsurfers, but also this wonderful sport has not yet become widespread. Obstacles are the relatively high cost of the equipment and the small scale of its production.
