What can be done with the board? For example, to saw. Measured out all that way just seven, tagging, sawing. Sawing, of course, a saw, but what? Saw, as we know, there are manual, electric and gasoline. Let's first look at what is a hand-held saws. In shops and markets of this good enough, and domestic specimens do not yield similar import.

Finally, we have learned how to make a strong fabric and more or less comfortable handles that work does not rub blisters on your hands. By the way, priced at "our" and imported saws do not differ very much. In one of the following numbers, I must tell you about hand saws in detail, but now I want to give a couple tips that you'll first need to know when buying a handsaw. First, never buy a hacksaw or replaceable blade (especially metal) in China. Sawing them poorly, and break down a well - probably because of infringement of tempering technology. This is - money thrown away. Secondly, there are now on sale so-called "self-sharpening" saws. How to explain the sellers saw "when working on its own to sharpen by friction of the material being processed." Therefore, they say, such a drink is always acute. Do not believe it - there are no miracles. It's like your car while driving will not only consume fuel, but also by its own produce. "Secret" of these "miracle drink" is ridiculously simple: cloth made of harder material than usual, so stay sharp several times longer. But remember: when the saw still becomes blunt, you will be very difficult to sharpen it again - because of the hardness of the material! (Incidentally, an ordinary hacksaw to sharpen with a file and needle files is simple - technology. Describe the process on paper - a thankless job. In every village there is a skilled craftsman, who will be happy to explain it to you "on his fingers.") Go ahead. Next on the list - electric saws. There are many models from different manufacturers, which naturally differ in price and quality. It is clear that the main difference between the available types of power saws - the principle of action, but almost all of them (to some extent) are interchangeable. We now turn to their classification. Saws, like everything else in this world are imported and domestic. Imports are divided into the disc (circular), jigsaw, miter (the principle of operation is the same as a disk), saber, chain and joinery elektronozhovki. Domestic share on disc, Jigsaw and chain. Other species, at least to me, is unknown. Let's start with the disk power saws. Cutting tool in them - a metal disc with sharp teeth, which rotates at high speed around its own axis. Circular saw is used to execute long straight cut. Saw can handle and move relative to the cutting surface, and can be mounted in the bed and saw myself moving treated material (for large volumes of work is best to act accordingly). Circular saws are very useful for dacha construction and repair. For example, a particular case. I have one friend - a man with "golden hands". He earned a very good idea - "work hard" from dawn to dusk. A long-awaited vacation spent in a stuffy Moscow. Sometimes, of course, must choose a resort, but .... Do not lay a human soul to such a relaxation. And he decided to build a house in the suburbs. Bought a plot, set frame, was to attach the veranda. And then - to the pain all the familiar story: the crisis, job loss, incidental and insignificant earnings ... In general, the frame is made under the terrace, and upholstering nothing - no "golden reserve. And then a miracle happened! Had the possibility of a peasant "privatize" Unedged in sufficient quantity for studding terraces. Well of course he still "slab" privatized, and then what? Upholstering terrace "slabs"? Ugly. Such a structure would be more like a shed, and need, as we know, terrace. And then it was bought in good stead in the best of times "circular saw" (which model - I do not know). In short, napilil man of the normal wood-edged boards - not "super", of course, but it is "at". Studded terrace, more and shed remains. And in his spare time, my friend took up the count. It turned out that in the end it is fully paid for the cost of their saws. This summer, a man quite well, "moonlight" through its "circular saw", that is, receives a net profit. Here's a story. But just in case I warn you: the circular saw pretty quickly pays for itself if you are doing construction in earnest and for a long time. When you perform a piece "works is to buy a saw consumer class and cheap, can be used. Now about the different types of drives for circular saws. First of all, the discs are carbide tipped and without napaek. Disks without napaek are usually used for obtaining pure and beautiful cuts in soft wood. With hard wood, and even more so with the metal, this disc will not cope. If a sawed board accidentally gets a nail, the disc will be "no teeth". Reanimate it is impossible: "false teeth" for these purposes shall be issued. In this sense, much more interesting model with carbide tipped. Such a disk is easy to saw those caught "on a tooth and nail peacefully continue their (your) work. But there have to live with the fact that working with such a drive drunk is not very clean, even the slightly "shaggy". The shape of the teeth: they are not afraid of the word, active (positive edge angle) and passive (negative edge angle). Let me explain: if the tooth is bent as if in the course of rotation of the disk - it is a positive edge angle, and if against the course - no. Positive angle can cut wood, wood with nails, plastic, etc. Negative angle can cut, for example, tin and copper. Theoretically, such drives can be cut and the tree, but the cut can be very "hairy": teeth are not trimmed, and torn wood fibers. So before you select the drive, you should determine which papers you need it? And sellers prompt a specific model. Now about the specific models. I am pleased to note that in Moscow, made circular saws that are not inferior to foreign analogs of any design or reliability. 1200 W, the disc 200 mm depth of cut - up to 65 mm, equipped with a protective cover.

Here, I brought the most interesting ones, but this does not mean that they can be seen in all the shops and on construction markets. There are usually sold copies of the simpler and cheaper. But with these simple, cheap power tools, we decided to put the kind of experience or, as they say now - had a "rating of". The essence of the process is this: we have two models of each of these manufacturers (one of those that can be purchased on the market), equipped them with exactly the same blade (domestic production), was dragged to the editor several identical spruce planks length of 6 meters and a thickness of 50 mm. And then we had chosen "a group of friends" among the editorial staff (including beautiful women) and asked them to take turns sawing the board along, using existing in the presence of electric saws. Then each model was evaluated on a five-point system and displayed an average score. Here are the results of this test. Black & Decker. Overall impression is good, although there are some drawbacks, especially marked by the weak half the editorial staff: not very comfortable handle (for a man with a little hand - not easy), a high level of vibration - it's hard to keep the saw exactly the cutting line. The result - 3.75 points. Bosch. Saws amateur class considered more suitable for holding in their hands, rather than glorious representatives of professional saws. The noise level is slightly higher than the Black & Decker, but the vibration is low. The result (in all amateur / professional class) - 4 points. Makita. Very good impression. They decided that the only drawback - a rather high price for this model. The result - 3.75 points. DeWalt. This model is like, perhaps more than all the rest, good design and comfortable grip. Noise and vibration levels low, the model is suitable for comfortable extended use. Price of the power of this class - quite acceptable. The only drawback, noted by our ladies - yellow body color. Say, got dirty quickly and will be ugly. But, on the other hand, a tool such bright colors readily visible in the grass - do not lose it. The result - 4,5 points. Skil. Here opinions differ. On the one hand, very much like an amateur model of firm Bosch, but are too "clumsy" handling the case, on the other - quite reasonable price. The result - 3,5 points. Milwaukee. Extremely rare guest in Moscow markets. I caught this instance, by the assurance of the seller, quite by accident. Impression is good, but the price is unreasonably high. For what we overpay - it is not clear? Declares that paying for quality, but this brand for Russian market - the new, and customer opinions on this subject has not yet happened. But in general - quite comfortable in the electric saw. The result - 3.75 points. Electric saw production of the Moscow Radio Engineering Plant (MRTZ) for its price a very good impression. Of course, certain disadvantages are (at whom they are not), but for the money they are all very small. The result - 4.25 points. Atlas Copco. Models from this manufacturer nor the markets, not in the shops I have found. However, in the office or representative told me that I'm bad looking, but agreed that the emergence of the brand in retail trade - a phenomenon often. Therefore, we have not been able to experience these saws, but in the future must test and tell. Speaking of circular saws want to emphasize: each model is designed for disk usage of a particular diameter. Larger diameter disc you just can not install it, and drive smaller unacceptable for safety reasons: in this case between the disc and guard a gap, which may accidentally get a finger. Given the speed - no thumb will stay overnight. No less useful in the economy could be jigsaw power saws, and saber elektronozhovki, and the chain saw can be useful, but more on that another time. www.material.ru
