How to choose a hacksaw on wood

Do not dying away their days hand tools today, when the spacecraft through the Universe? Shows the dynamics of sales and the competition of manufacturers - far from it. He is still irreplaceable in many cases. Should I pull the mains wherever you can go with a hacksaw and a hammer. And if there is no electricity at all? In the construction business relationship between hand and power tools as between the theater and film: there are parallel, not only disturbing, but sometimes helping each other. Do not dying away their days hand tools today, when the spacecraft through the Universe? Shows the dynamics of sales and the competition of manufacturers - far from it. He is still irreplaceable in many cases. Should I pull the mains wherever you can go with a hacksaw and a hammer. And if there is no electricity at all? In the construction business relationship between hand and power tools as between the theater and film: there are parallel, not only disturbing, but sometimes helping each other. Fighting for the buyer, the company improve its model series. It would seem, why reinvent the wheel? However, in practice, differences in products of the same class is so much that I have to spend some time on model selection. To help our readers in this difficult case, we conducted a test Hole Saw Timber. But before proceeding to a description of the results, you need to talk about some of them (Hole Saw) features. How to choose a Hacksaw's main provisions, which should guide the choice. The material being cut. Which material is your saw will work? What are the expected size of the processed billets? Of course, not every problem has a special drink, but the basic laws work here is very clear, and sensible counselor, knowing the range of your requirements, be sure to select the optimum option. Quality of cut. Where necessary the exact propyl (eg, furniture repair) is better to use hacksaw with a small tooth. For a quick (and rough) cutting saws are designed with large teeth and a long blade. The length of the blade. The convenience and accuracy of a hacksaw with a fine tooth blade length has virtually no effect. But the big tooth is effective only on the energetic propylene, so that the cloth should be long enough. For medium-sized tooth is also true. These saws have a length of 450 to 500 mm. Material fabric. Cloth, typically made from stainless steel. Simple test fabrics for durability - bend into an arc equal to half the circumference. "Correct" Saw then required to restore the original appearance. Teeth. Each of them - an elementary tool in the form of a wedge. Which of its surfaces, cutting, grinding depends on the form. This defines the range of tasks, and Sabre. There are special models for longitudinal and transverse cutting of timber. However, the most common wood saws with a universal tooth - they can cut wood in both directions. Dimensions of teeth determined by the height and width, but for simplicity has been introduced another parameter - the number of teeth per inch, or the number of peaks per inch (the second one more than the first). The more these figures, the saw blades less, and vice versa. Important point - the hardening of teeth: if it is, then saw a long time (5-6 times longer than normal) will retain its enchanting, without washing, even on materials that are not "in the teeth" simple hacksaw. But this convenience can not be used "forever": blunt hardened cutters are not re-sharpened. Plays an important role and wiring saw. It determines the quality of cut and ease of operation. Arm Saw. Form of the handle should provide a solid grip without slippage. Otherwise be difficult to cut, and you can easily earn corn. Most of arms - two with rubber inserts. Ergonomically designed handle effectively transmits force to the sheet, distributing it evenly across the surface. Test conditions for the test, we tried to pick the same Sabre, but to accomplish this task is not fully succeeded. Nevertheless, despite all the differences between each of them to satisfy basic requirements: the length of the cloth - no more than 500 mm, number of teeth per inch - 7-8 (exception: Brigadier - 6 teeth and Bahco - 9). All cutters - universal (for the longitudinal and cross cutting), and seasoned. Six such hacksaw we sawed wood eight samples of different geometry, moisture and hardness, making several visits to each material. In this case, chronograph was measured the total time of all cuts, including the installation of motion. By the way, the duration of the initial stage of cutting in different models of significantly different. All samples were cut transversely, and the pine and birch boards try to work with large and longitudinally to test the universality of instruments. TEST RESULTS Bahco 2500XT original technology applied in the model we tested 2500XT, is a firm geometry of the tooth - XT. In accordance with her divorce only every third tooth. He also has a three-plane grind, unlike the two undiluted, cloistered in only two planes. Tempered after this treatment, the cutting surface, hacksaw get increased productivity and accuracy. The canvas is her very carefully any material, since the friction on the lateral surfaces of the teeth and jam at the entrance to the wood to a minimum. Among other things XT-edge geometry provides a high removal rate filings. Ergonomic Hacksaw evenly distributes force across the surface of the fabric and fits in the palm: the capture of very dense. The quality of the surfaces will vary depending on the pressure: it is stronger than the more burrs. Despite the fact that the 2500XT is designed for cutting materials of medium size (according to the manufacturer's label), with large samples, it does a no worse Hole Saw with big teeth. When working with small workpieces same accuracy it is admirable - it can literally "catch" millimeters. And at the beginning of cutting no problems: cutting begins without a single installation of movement and right in the selected location. Saw a very well managed with a moist material, pilila even faster than dry, but on the solid rock a little "hesitated." It was more difficult to do, and longitudinal sections. SUMMARY: high-quality hacksaw with an excellent "working capacity". And although the manufacturer recommends using it for pieces of medium size, it copes with large and with small samples in the first case demonstrating the performance, while the second - precision. Brigadier Jetshark 63203 Big size of the teeth saws easily explains its performance when sawing large samples. In addition, handle shape and guide promotes a uniform distribution of effort across the cutting surface. So it is possible, without compromising ease of cutting, or work slowly and precisely, or fast, but with large burrs on the edges. Workpieces in small work it is almost as comfortable in what undoubtedly merit designers Jetshark. However, when cutting thin samples should not be too zealous in order to avoid problems typical for Hole Saw with big teeth - inaccuracy washed down, sticking tools, chipped in the final stages. For cutting parquet such hacksaw, of course, will not work. But for construction, for example, a bath - just right: with "rough" its performance is worthy of all praise. Solid wood and wet wood it cuts no worse than a dry pine. The only disadvantage identified was a significant decrease in speed and comfort of passage for longitudinal sawing (both hard and soft wood). So it is better if the solution of such problems will be a small fraction of the entire front of the work Sabre. SUMMARY: The model is intended primarily for sawing large materials, fit and work with the average samples. Good passes on the track any effort. At the middle and large push shows very high performance and a small flat leaves and tidy sawn. CK Senso Plus 947 Handle user-friendly design with recessed under the fingers in non-slip rubber insert makes the "management" hacksaw. She sits in the palm of your hand tightly with her touching, and effectively transmits force to the teeth. Angles of 90 and 45 degrees marked on the handle with a cloth handy for simple marking papers. According to feelings of cutting hacksaw "CK" can be recommended primarily for precision work. Despite the long blade and not the smallest size of teeth, it's more accurate than performance. Sawing her 7-centimeter bars rather tiresome, but "catch millimeters, on the contrary, it is convenient. In addition, the surface took to drink get a very smooth with small burrs, chips are rare and only when working with great effort. Best hacksaw showed itself on thin blanks: no problems with the primary "vgryzaniem" in the material, sawing began, without any installation movements precisely where the "ordered". Medium and large samples, it was quite bearable. With the wet and solid wood model of Senso Plus 947 coped less well, as with the conventional - the difference is palpable. A lot of effort required and resaw: Hacksaw almost does not produce material moving "over", so the cutting speed has declined substantially. In general, cutting with "CK" was comfortable and neat. SUMMARY: Professional handsaw for work on materials of medium and small size. Occasionally can be applied for cutting of large workpieces. Performance Sabre relatively low, but it is accurate and gives a very accurate surface without burrs and scrapped. Stanley Jet Cut 1-15-283 Jet Cut - one of the few Hole Saw, fully justified the name "universal". Regardless of the hardness of the material to make longitudinal gash it almost as easily as a cross. In general, the hacksaw was akin to a powerful race car - a large stock performance, which is not always possible to implement. Somewhere in the middle of the test had come back to the beginning and re-sawing all the samples, as has been proved by experience at first glance paradoxical fact: the model saws faster when the pressure on it is minimal. If you put extra effort, big teeth when moving from a permanent burrow into the tree, leaving unused near-third of the canvas. So one rule: to deter their energy, and work will be easier. Exception - a longitudinal cut. Here the stronger, faster. From my own experience indicates that psychologically difficult to cut without pressure on the hacksaw. But if you adapt himself, the performance of Jet Cut will be very, very good. Use a hacksaw Stanley is better than smaller samples. In this case, most of the time is not the process of cutting and mounting traffic. This is the reason for the 10 cuts of pine bar section 35h25 mm took so much time - 107 seconds. On the hardwood speed increases, because if you press on the hacksaw teeth stuck less. But the humidity of the material almost no effect. SUMMARY: Productive hacksaw for large and medium-sized samples. If you adjust to some of its features, can achieve high performance. When working with small workpieces low accuracy and a lot of bend at the cut. Hacksaw copes well with resaw any of the hardness of materials. Stayer Cobra Professional 1513-45 from the design features of the model to allocate larger compared to other saws handle. According to test results, it was very convenient - Saw tightly and comfortably rests in the palm, and rubber components that made the whole inner surface of the handle, eliminate slippage. Material blade is good - when bent hacksaw arc in a half circle the original form is restored. PCB raises no objections: paint marks on the canvas virtually erased (in case of bad wiring canvas "rubbing" would be a blank). "Cobra" pleasant to work with samples of large size, here she is "at ease". The average harvesting it, too, "the teeth", but for thin strips or, say, the baseboards do not recommend this hacksaw - to saw cut is a lot of chips and burrs, and accuracy of input into the material is not ideal, because a relatively large tooth. With varying density and moisture content of wood Cobra handles with equal ease. And for hard rock (larch, oak, birch) to operate it even better than the soft (pine) - accuracy is higher and smoother motion. For the majority of cases (particularly for soft wood and thin pieces) the main conclusion is as follows. And the performance of Cobra, and ease of use is much higher if the cut with little effort. Yes, and took to drink in this region will be more accurate. Commendable versatility saw - "Cobra" is one of the few to justify this title. Cutting wood in the longitudinal direction is almost as easily as in the cross: the accuracy and speed remain high. SUMMARY: Productive hacksaw for household and professional goals with a good quality / price ratio. Suitable for large and medium-sized workpieces, regardless of the material with small samples is more complicated. The test confirmed the universality of the "Cobra" - cut equally comfortable in both the longitudinal and transverse directions. Encore "Beaver" 9852 In the tests with the best hand proved to handle design - Hacksaw fits snugly in the palm of your hand without slipping and good passing effort on the cutting surface. While painting on reflection was somewhat different from other saws, the test is confirmed to the manufacturer high quality steel. Bending his arc in a half circle it always restored the original appearance, and during slid very well. This went a long way and quality wiring of the teeth. The speed of "Beaver" is not inferior to many hacksaw with a worldwide reputation. Dependence of the quality of the applied load is fairly standard: the more pressure the better the performance, but worse than the state of the surface (burrs, broken, etc.). Large timbers cut tedious, so it's best if the main activity of "Beaver" would mean cutting materials. This is supported by and good accuracy: to start sawing on different samples (large or small) can be easily and conveniently, in the assembly motions is not necessary. For small pieces "Beaver" is also quite suitable, however, if there are no strict requirements for quality saw cut: burrs still remain, and chips sometimes occur. With wet wood and solid rocks hacksaw handles worse than the standard bars. For longitudinal sawing performance drop is strong. So that the name of a tooth, "Beaver" - "universal" - conditionally: a hacksaw can cut along, but rarely better. SUMMARY: The hacksaw is designed for standard billets average and is characterized by precision obtained sawn. You can work on other samples: at least for large, often on small - accuracy allows. In general, "Beaver" is quite suitable for professional use: in the hand is reliable, hardened teeth are well separated, the cloth is moving freely. mastercity.ru
