In the cramped conditions of the home, whether in a small apartment or in the country, the offered sofa is convenient because during the day he takes up very little space, and in the evening can turn into a normal comfortable bed. Such metamorphoses are explained gem that the sofa is a structure able to fold to fold, being depending on the need in one form to another. The whole structure is assembled from three separate wooden platforms, connected by hinges, allowing the platforms to change mutual arrangement. Two of them absolutely identical and the third differs in that it is bilateral. What caused it, it will become clear from a more detailed consideration of their device.

Utilities are widely used shut-off valves — they are in all water inlets in the house and each apartment. Earlier these devices were made of iron or steel: casing — cast iron, and the remaining parts (except seals) — steel. Such gates are still many in the water supply systems, although most of them are not working: their thread has long since rusted and the stocks firmly rooted to the heads. And these are “rarities”, playing only the role of coupling, but unreliable, as the water through the hole in the head stem still leaks.
When a small room for a student or a student does not establish a standard store-bought furniture because of its size, the solution may be compact and simple construction, proposed by the French magazine “System D”. It is small but large enough bookcase, in the traditional “classical” style of furniture, structurally subordinated exclusively to functional tasks and therefore devoid of decorative elements, which makes it available for self-production.
The journal “modelist-Konstruktor” I love since childhood. In Kazakhstan we have now it is not for sale, but I regularly read it in the library. Responding to the call of the editors to be not only a reader but also an author, I want to share my little experience performing turning operations on a tree without a special lathe. To do this, at the right time are available to me elektrotochilo and grip, adding to them two auxiliary elements: the Trident and the back area with a small thrust bearing (they then shall say more about). Bench grinder with a Trident causes a wooden block into rotation and vise play the role of the tailstock.
This stove I installed in the bath at their summer cottage. For ten years I use it and is very happy. The furnace body of metal, is welded from a steel sheet with a thickness of 5 mm. From the same sheet made and all other elements of the heating device in contact with the fire. About the same thickness and have the flame tube. The remaining flat parts from steel sheet of thickness 2 mm. Metal variant of the furnace design is selected for several reasons: first, for such stoves do not require massive foundations; second, it can be manufactured in a different, more adapted place and then transported and mounted in the bath; third, it quickly heats the room that country bathhouse is highly desirable.
On the Sunny balconies in a city apartment or on the green lawn of a suburban area nice to sit in a comfortable chair-a lounger. The design proposed by the Hungarian magazine “Earmaster”, different from the traditional schemes of sun loungers by the fact that the chair is not just foldable and detachable. Actually it’s two independent frames, one of which, the seat is inserted into another, playing the role of the back. Each of them has its own characteristics, to ensure the reliability of a reciprocal link in position without additional fastening elements. Consider each frame separately.
