Each self-respecting man in his collection of tools necessary for the farm has a hacksaw for wood. Without it, it is difficult to do without construction and repair. A hacksaw for wood is also indispensable in the care of a personal or country plot. When choosing this important tool, one should be guided by its basic characteristics: the length of the blade, the size of the tooth (small or large), hardening of the teeth or its absence.
Hacksaw on wood should be quite long. This will allow to saw wooden products of almost any thickness. Hand hacksaw for wood, which is about 30 cm in length, is suitable only for sawing small bars and rails. For the work with boards and logs, the saw with the canvas of 45-50 cm is optimal. The size of the saw blade affects the speed of cutting and the cleanliness of the cut. As a rule, the smaller the teeth, the smoother and cleaner the cut is. The fastest sawing is facilitated by a hacksaw blade with 6-8mm teeth. Such a saw is best to work with conventional logs, boards and wherever it does not matter what the cut quality is. For work with furniture plates, decor elements, and where a smooth and clean cut is required, a hacksaw with small teeth (up to 3 mm) must be used. Such a tool requires more time for sawing, but the cut will be more accurate. There are also varieties of saws on wood, on the canvas of which there are both small and large teeth. Such saws are called "Kremlin hacksaw". In addition to the distance between the teeth, their shape is still very important, since it determines the direction of sawing. Saws with straight teeth are used for lateral sawing of wood, and with slightly inclined forward - for longitudinal. Hacksaws with teeth sharpened from both sides well saw when moving forward and backward. Such differences of this tool lead to the fact that experienced masters always have several of their kinds.
Also, you should carefully consider the degree of hardening of the teeth. So, roasted serve much longer, and at the same time they are not blunted for a long time. When using such an instrument several times a year, it can serve as a faith and truth for life. Such teeth are simply impossible to sharpen, therefore they are considered disposable. Unblocked hacksaw blade allows you to sharpen teeth many times. Such saws are best suited for permanent use. The calf teeth differ from the simple ones with their black color.
Sharpening of the hacksaw on the wood is a crucial moment, as it is incorrectly produced, it can completely ruin the tool. For her use special files with a small notch. They are usually marked with the letters "road accident", which means "for sharpening the saws." To completely restore the sharpness of the tooth, you need only a few movements of the file. Abrasive wheels are used for quick grinding . To distribute the teeth of the hacksaw, a special device called "wiring" is used. In this case, each tooth is bent to the side (alternately right-to-left) along the entire length of the saw. The quality of the teeth can be easily checked during operation. Correctly bred hacksaw on wood almost never gets stuck in the wood during its sawing.
