Information stored in the computer, it is sometimes necessary to put on paper. The result typically looks like a stack of A4 sheets, stapled one side with a stapler. But easier would be to have a printout in the form of smaller format books, a small notebook of nested into each other bent sheets, or (if the pages of many) of several such notebooks, stitched together. How can that be?FLEXIBLE NOTCHED
Blanks of sheet metal with a thickness of 3 – 5mm will be more accurate and easier to bend at home if they are pre-trimmed along the fold lines using the grinder (and if the workpiece is not very long, and with a hand saw) about a third of the thickness of the sheet. And Read more…
In the multi-individual homes usually have Autonomous water supply system, which consists of a boiler, pipes, radiators and the surge tank. The inner walls of the tank is always wet from the constant evaporation and wetting with the expansion of water in the heating system. The reservoir is intensely rust inside and rust and fills the system, threatening congestion.
Even in the recent past 10АС9 sound system, each sound column which contains two versatile dynamic loudspeaker (one for low and medium frequencies and the other, with a diffuser of smaller diameter for higher), it was considered perfectly acceptable for a home stereo. And electrical parameters it was on a high level: power 10 W, impedance DC current 4 ohms, audio frequency response 40 to 18,000 Hz. With the advent of so-called Hi-Fi equipment these speakers have become increasingly depart among the almost Museum pieces.
The homebrew is often used segments of rubber hose as a flexible coupling when connecting coaxial shafts, particularly in those cases where the rotation speed is small, and the shafts are not strictly coaxial. This way I decided to apply when I built the frame of the greenhouse from the chimneys of the old clamshells.
