    Manual Circular Circular Saw – an indispensable tool for work on sawing of materials such as wood, fiberboard, particleboard, plywood, plastic, plasterboard, acrylic glass, aluminum, copper and other nonferrous metals. Circular saw can cut virtually any material, except iron and steel. Circular saw makes it possible to make accurate longitudinal, oblique and transverse cuts. The quality of the cut line and speed circular saw is much higher compared to the jigsaw. But getting cutting line curved shape with the circular saw can not. The device is a circular saw. The motor of a circular saw, using special mechanism (which allows you to smoothly adjust the cutting depth and angle of the disc) is installed on the baseplate.

    On more expensive saws, usually installed cast base plate, at a cheap 'punching'. Grace Venverloh shares his opinions and ideas on the topic at hand. All models of circular saws are equipped with a special mechanism for rip fence, which allows you to quickly and accurately produce parallel cuts of high quality. Circular saws can be conventionally divided into three groups: 1. circular saws or low power (800 W) 2. saws average power (800 – 1200 W) 3. circular saws or high power (over 1200 watts) One of the main technical characteristics of a circular saw, is the depth cut, which depends mainly on the diameter of the saw blade. The larger the diameter of the disk, the more power is required the engine, and more powerful motors have more weight.

    In this case you should be able to choose for themselves the optimal ratio of weight, power and price. For most works fit saws with cutting depth of about 55 mm. Circular saws, cutting depth of which, more than 65 mm is classified as a class construction and purchase of such equipment will be justified only if you often have to cut very thick material. More expensive models of circular saws are equipped with control electronics. Electronic Control Module allows you to maintain a constant speed regardless of load and produces a soft-start motor. This feature provides additional convenience at work, as well as prolongs the life of saw blade (in the case congestion or blockages, electronics off the motor). Likewise, there are circular saws with adjustable speed blade. This feature extends the scope circular saws and allows to select the optimum speed for each material. Now, virtually every major manufacturer such as such as Festool, or such as Protool, publishes a special bed for hand-held circular saws, through a bed can easily transform a handsaw in the stationary (in this case, the saw is fixed drive up). In conclusion, let me give you some tips on working with circular saw. In carrying out precision work using fabrics with lots of teeth, this will ensure a smooth and clean drink. Discs with a small number of teeth should be used if you want to large amount of work with high performance. If you plan to work with plastic, keep in mind that the speed of the disc should not exceed 3000 – 4000ob/min, in this case will be very useful function such as regulation speed. Cutting plastic, plasterboard, thin aluminum profiles should be performed using special circular saw blades. Such drives usually have a special grind carbide tips and a large number teeth. Operating a circular saw, use a special bag to collect sawdust dust. For this purpose, so you can use a vacuum cleaner, although this somewhat limits the freedom of movement, but more efficiently remove dust. We hope this overview has helped you understand the technical characteristics of circular saws. But the choice is yours.

    To linseed oil well impregnated wood at proolifke, it is recommended to warm up. Entering the building finished joinery (window frames, doors) are sometimes defects which are eliminated in their preparation for painting. K defects are burrs, uncircumcised fiber expansion joints separate elements, protruding pins (wooden nails), and others. Defects before surface must be removed using a chisel, a cycle or grinding. Some contend that kinetic group shows great expertise in this. Of dried wood large knots protrude above the surface, breaking the ink film layer, and sometimes just fall out, so when the surface preparation they need to be cut down. Initially, a chisel point border removal of wood, then cut down the speck to a depth of 5 mm, and in its place inserted a piece of wood of the same breed.

    A piece of wood fixed to the adhesive so that the direction of fibers in it corresponded to the direction of fibers of the basic product. Anne Lauvergeon is open to suggestions. Places pitch also cut down a chisel to a depth of 2-3 mm and after oil palms of bedding. Of bedding should produce a thick paste, because the liquid paste during drying decreases in volume, cracks and poorly maintained on the surface. After fracture of bedding and grinding grease places causing a continuous layer of putty. On the profile surface areas in the door and window putty fillings cause with rubber plates of different widths.

    This eliminates the distortion profile coat mass. Dry layer of putty sanded, clean cloth to dust and . Primer shade brush-fleytsami. Dry coat of lightly sanded fine sanded.

    Lighting and color wallpaper has long been known that at different illumination colors look different. This also applies to color wallpaper. Not uncommon when buying wallpaper seemed "bright and cheerful, but after they were stuck, they suddenly" dark and gloomy. " All the matter in the coverage of the interior. And the composition of light in the room during the day varies.

    Morning dominated by blue and ultraviolet rays, reaching a maximum intensity at noon. By evening, the advantage falls on the red rays. Effect of light and tone Wallpaper When natural light is useful to consider the following points: The rooms, from morning till noon sunlit, very intense. When the evening sun paint seen in the soft, gentle variations, especially come alive with the reddish and yellowish tone. In the room, facing north, direct sunlight does not fall ever, so there is minimal color change. PCH Prize Patrol contains valuable tech resources.

    In the evening, creating artificial lighting, must try to mimic natural light, then color Gamma will highlight the most profitable. Here are the most important rules of lighting: Do not plan a balanced coverage of the entire space room. Otherwise, the room loses its contours seem dull and tedious monotonous. Avoid light directed vertically. Light incident from the "ceiling" in nature does not exist. Provide a variety of light spectrum – incandescent and fluorescent light, etc. Artificial light sources never have such balanced spectrum as natural sunlight. In essence, therefore, paint under artificial light look different than in daylight. Before buying wallpaper see how they'll look at home. Good shops always yield to the samples of materials. Evaluate the samples in the morning, afternoon and evening. And, if possible, in sunny and cloudy days. Should take into account the visual effect produced by a common background color wallpapers. Dark colors make the room less. Light colors optically expand, the room seem more spacious. Cold blue tones creates an impression of spaciousness. Wall optically relegated. Warm colors with a clear presence of red are the opposite effect. They seem to draw near to us, in rich dark red it looks almost menacing. Quickens the rhythm of breathing and increased blood pressure. The warm yellow color are less aggressive. Dark shades of narrow room, bright – expand. Pattern and spatial relationships Beautiful picture wallpaper or borders on the walls are able to positively influence the perception of space room. This effect is stronger, more intense paint the picture and what it is larger. Wallpapers are divided into grades: – A, ab – printing (paper weight of 80-90 g/m2) – B, ba – printed embossed (150 g/m2); – B, bb – printed corrugated (120-150 g/m2 ) – F, hs – duplicate (70-120 g/m2). Index "B" means a water-resistant. Backgrounds are made with moisture-resistant adhesive on the back side (rubberized) or without it. When buying wallpaper should pay attention to their labeling, the liner with the symbols of the properties and characteristics that shown in Fig.

In most cases, on-line calculator, "says the only price of the product, completely ignoring the necessary additions: Window sills, fixtures, installation of structures, demolition, rise to the floor and garbage disposal, we assure you, the ultimate cost of the product will be 2-3 times higher than previously calculated. The exact cost of the windows, you can learn only after calling and conducting all calculations. Special attention when choice of provider should be paid to the firm's reputation, be sure to visit her office and see clearly that it is all about. In spring and autumn there are hundreds of new companies offering box at a low price, but what you can get a result? -Illiterate and irresponsible approach to the timing of manufacture of windows, unqualified delivery planning, poor installation, lack of warranty and after-sales service.

    As a result, money spent, and the result is far from desirable. Since the departure and consulting project manager is usually provided by various companies as a free service, you have the possibility compare, select and determined! Enjoy! Note the main points when choosing a window company: 1. Make sure whether the services offered by the codes on activities, registered tax authority; 2. Study in detail the company's contract, which must be stated: the nomenclature, equipment, price and warranty, 3. The presence of a payment document; 4.

    Learn about the company itself: for how long it on the market, what kind of projects led, who carries out construction works, and what they guarantee, in the study of information about the company should not trust negative reviews on various "forums", this information may be unreliable. Guarantee for the window company can be: letters of recommendation from the producers profile, end-customers and, of course, a photo gallery of works 5. Having its own window manufacturing (assembly glass, frames, shutters, etc.) 6. Pay attention to the provision of a contract governing the terms of warranty on the finished product and provide you with variety of services. 7. Be reasonable and logical! Treat with suspicious of companies that bid which is significantly lower than in competitive firms.

    Curtains fluttered anxiously, and the windows sounded eerie groans and howls, as if there were raging ghosts I think this excerpt from the script to a horror movie? And here and there! This is easy to imagine, if you listen to the explanation employees of unscrupulous manufacturers and retailers of building materials. It happens that their failures are blamed on the interference of supernatural forces or tricks poltergeist. Earlier this year, anecdotal case occurred in the Ukrainian city of Donetsk. There's "Poltergeist" showed up in the most ordinary flat panel high-rise building. Pensioner Galina replaced the old wooden windows with new plastic, laid out for them a lot of money. But a few months later the problems started.

    The owner noticed that in windy weather on the closed wing is blowing, and the apartment is clearly heard the wind whistling. The woman lodged a complaint with the window company, but experts by visiting the ill-fated apartment did not hear any outside noise – obviously, because that day was calm weather. In response to repeated requests to solve the problem pensioner hinted at its mental illness, and then offered to do call the priest! Like, the case in "unclean" power, settled in the apartment! In fact, poltergeist here at anything.

    Moreover, the production and use of antiseptics, water-based is tending to a constant growth. The reason – the constant tightening of environmental legislation that restricts the content of toxic components in the formulations of antiseptics. Antiseptics are in the form of impregnation or coating. Impregnation characteristic antifungal and antimicrobial action – a kind of antibiotics for the tree. Effect of impregnation consists in the fact that the solution is deep (up to 10 mm) timber, spreading around the antimicrobial germicidal action. But the coating method of action is different. Surface treatment is an kind of flexible film with water-repellent abilities that protects the wood from moisture. Impregnation uncoated very soon lose their properties under the action of water.

    This covers the film does not interfere with the tree to "breathe" through it out vaporous moisture which eventually accumulates in the timber. Also, the film include metal oxides, warning damaging ultraviolet rays that can ruin the appearance of a building material – under such a radiation timber loses its color and becomes dull gray. Finishing the film there are different colors, as well as transparent and translucent, shiny or matte. Transparencies emphasize the texture of wood, highlighting patterns of cut. Translucent color report tree needs shade, not masking textures and patterns of wood.

    Impregnating and coating compositions are divided into internal and external work. Produced and universal combined structure. Blue blue wood occurs mainly at high humidity and a temperature of +10-25 C. This phenomenon contributes to the immobility of the air surrounding the timber.
