Three types of hand saws: what are the differences
For those who did not know, we inform you: hand saws are divided into three types. Some of them are designed for cutting wood across the grain, others for working along, and there are universal saws that can cope with both tasks. It is the universal ones that are most common. And it is quite simple to determine the type of saw: the teeth of the cross-cut tool have the correct shape, for longitudinal - a strong bevel in one direction, universal have one face at a right angle, and the other - beveled. Cross-cutting is carried out in two directions, that is, the saw blade moves back and forth, with a longitudinal saw, the saw only works in one direction. Accordingly, when sharpening teeth, these nuances must be taken into account.
How can you sharpen a saw
Hand saws are made from corrosion-resistant alloy steel. This material perfectly retains its sharpening during constant use and does not lose it, even if the hacksaw is not used for a long time. The exception is some modern models, in which the edge is hardened, this cannot be diluted or sharpened without preliminary annealing.
With a certain skill, you can sharpen a saw and an electric sharpener with a circle up to 8 mm thick made of white stone on vulcanite with a grain of 120-140 and a diameter of 120-160 mm.
How easy it is to spread the saw teeth
Before starting sharpening, the teeth must be returned to the working position, that is, diluted. The easiest way to do this is with a regular hammer, nail or self-tapping screw and a softwood plank.
The spreading must be done before sharpening, so that later not to damage the edge of the tooth and so that the setting is even, which is difficult to achieve later.
How to conveniently attach the saw for sharpening
To work with a file or a file, the hacksaw blade must be in a strictly vertical and firmly fixed position with the teeth up.
