Every self-respecting man in his collection of necessary tools in the household has a wood hacksaw. It is difficult to do without it during construction and repair. Also, a hacksaw for wood is indispensable in the care of a personal or summer cottage. When choosing this important tool, it is necessary to be guided by its main characteristics: blade length, tooth size (small or large), hardening of teeth or its absence.
The hacksaw should be quite long. This will allow sawing wood products of almost any thickness.
A hand saw for wood, the length of which is about 30 cm, 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 best suited. The size of the hacksaw tooth affects the cutting speed and the cleanliness of the cut. As a rule, the smaller the teeth, the smoother and cleaner the cut. The hacksaw blade with teeth of 6-8 mm contributes to the fastest sawing. Such a saw is best to work with ordinary logs, boards and where it does not matter what quality of cut. To work with furniture plates, decor elements, and where an even and clean cut is required, it is necessary to use a hacksaw with small teeth (up to 3 mm). Such a tool requires more time for sawing, but the cut will be more accurate. There are varieties of
saws on wood, on the blade of which there are both small and large teeth. Such saws are called "Kremlin hacksaws." In addition to the distance between the teeth, their shape is also very important, since it determines the cutting direction. Saws with straight teeth are used for cross-cutting wood, and with slightly tilted forward - for longitudinal. Hacksaws with sharpened teeth on both sides saw well when moving forward and backward. Such differences of this tool lead to the fact that experienced masters always have several of their types.
You also need to carefully approach the degree of hardening of the teeth. So, red-hot serve much longer, and at the same time do not get dull for a long time. When using such a tool several times a year, it can serve faithfully for life. Such teeth are simply impossible to grind, so they are considered disposable. An unhardened hacksaw blade allows you to
sharpen your teeth many times. These saws are best suited for continuous use. Red-hot teeth differ from simple ones in their black color.
Sharpening a hacksaw for wood is a crucial moment, since improperly produced, it can completely ruin the tool.
For her use special files with a small notch. Usually they are marked with the letters "accident", meaning "for sharpening saws." To completely restore the sharpness of the tooth, you need only a few movements of the file.
Abrasive wheels are used for quick sharpening
. For hacksaw teeth, a special device called a “wiring” is used. At the same time, each tooth bends to the side (alternately left and right) along the entire length of the saw. The quality of tooth breeding can be easily checked during operation. A properly bred hacksaw almost never gets stuck in the wood during sawing.
