Every self-respecting man has a wood saw in his collection of household tools. It is difficult to do without it during construction and repair. Also, a hacksaw for wood is indispensable in the care of a backyard or summer cottage. When choosing this important tool, you must be guided by its main characteristics: the length of the blade, the size of the tooth (fine or large), the hardening of the teeth or its absence.
Hacksaw should be quite long. This will allow sawing wood products of almost any thickness. A hand saw for wood, which is about 30 cm long, is only suitable for sawing small bars and battens. For working with boards and logs, a saw with a blade of 45-50 cm is optimally suited. The size of the hacksaw tooth affects the cutting speed and the cleanliness of the cut. As a general rule, the smaller the teeth, the smoother and cleaner the cut will be. The fastest sawing is facilitated by a hacksaw blade with teeth of 6-8 mm. It is best to work with such a saw with ordinary logs, boards and where it does not matter what the quality of the cut is. For work with furniture boards, decorative elements, and where an even and clean cut is required, it is necessary to use a hacksaw withfine teeth (up to 3 mm). Such a tool requires more time for sawing, but the cut will turn out to be more accurate. There are also varieties of saws for wood, on the canvas of which there are both small and large teeth at the same time. Such saws are called "Kremlin hacksaws". In addition to the distance between the teeth, their shape is also very important, since it determines the direction of sawing. Saws with straight teeth are used for cross-cutting wood, and with slightly inclined forward - for longitudinal. Hacksaws with teeth sharpened on both sides cut well when moving forward and backward. Such differences in this tool lead to the fact that experienced craftsmen always have several types of them.
You also need to carefully approach the degree of hardening of the teeth. So, hardened ones last much longer, and at the same time they do not become dull for a long time. When using such a tool several times a year, it can serve faithfully for a lifetime. Such teeth are simply impossible to sharpen, so they are considered disposable. A non-hardened hacksaw blade allows sharpening teeth many times. These saws are best suited for continuous use. The hardened teeth are distinguished from ordinary ones by their black color.
Sharpening a hacksaw for wood is a crucial moment, because if done incorrectly, it can completely ruin the tool.
For her use special files with a fine notch. Usually they are marked with the letters "accident",denoting "for sharpening saws." To fully restore the sharpness of the tooth, only a few movements of the file are needed. Abrasive wheels are used for quick sharpening. To set the teeth of a hacksaw, a special device called a "wiring" is used. In this case, each tooth is bent to the side (alternately to the right and left) along the entire length of the saw. The quality of the teeth setting can be easily checked during operation. A properly set wood saw almost never gets stuck in the wood while sawing it.
