Saw blades help us to reduce a lot of physical strength. Although many machines are highly automated now, there are still many hand tools. Hand saw blade is one of them. There are many kinds and specifications of hand saw blades. Different kinds and specifications can be used to saw different things, and the scope of use is still relatively wide. So, what are the specifications of hand saw blades? What kinds of hand saws are there? Where can I apply it? Now Bian Xiao will give you a detailed introduction.

What are the specifications of hand-made saw blades?

The number of teeth per 25mm length is indicated by the model of hacksaw bar. Usually it goes like this:

1) serrations, and the corresponding pitch is (0.8,1mm); The number of teeth within 25mm is 24 to 32.

2) Middle serration, corresponding to the tooth pitch of (1.2,1.4 mm); The number of teeth within 25mm is 18-22.

3) Coarse serrations, corresponding to the tooth pitch of (1.8 mm); The number of teeth within 25mm is 14- 16.

How to make hand-made saw blades

1. Prepare clean materials, drill and saw button holes.

Sawers need net material size. Based on the mortise wood surface, perpendicular to one side. Proofread with a square if necessary.

Key points: drilling the saw buckle hole based on the mortise wood surface can ensure the verticality of the saw buckle hole and the accuracy of the saw beam tenon and mortise.

2. Saw buckle and saw beam mortise

The saw buckle is made of wood or metal, and its length is 10- 12? Cm. What is the diameter of the wooden saw buckle 1.2? Cm, the diameter of metal saw buckle is 0.8- 1.2? Centimeter.

3. Sample modeling of saw handle.

First draw a basic straight line on the saw handle, and then draw it into a smooth shape with equal width. Enter the next molding and manufacturing process.

A tenon saw with a saw blade less than 50 cm can be made into a saw buckle by fixing the lower handle. (The center point of the lower handle saw button is a 45-degree inclined plane)

Step 4: Saw the beam

Selection of sawing materials: straight and light wood such as Chinese fir, Korean pine and white pine are preferred. It is not advisable to use heavy objects (heavy objects for sawing beams or ropes), so that the original center of gravity on the saw blade moves outward and loses balance, and there is an uncomfortable grip when sawing. As the saying goes: light sawing means heavy planing)

Break your teeth.

Mortise and tenon saw: the tooth is broken at a certain opening (the sharp saw seam after tooth opening is about 1.5 times the thickness of the saw blade).

Tenon saw: The teeth are broken with a certain opening or a certain opening.

saw setting

It is best to clamp the saw blade on the file tooth. The file teeth extend from left to right along the direction of the teeth. The file and the teeth must be balanced and vertical, and there can be no seesaw phenomenon.

7. Saw blade finishing:

Both ends of the saw blade should be rounded, the back of the saw blade should be rounded, and the saw blade teeth on the saw buckle should be rounded to avoid cutting hands when using.

What kinds of hand saws are there?

There are many kinds of hand saws:

1, woodworking: woodworking saw (divided into vertical saw and horizontal saw according to the use function and sawtooth arrangement), woodworking knife saw, two-person band saw (also called fast horse saw or two-person grab) and edging saw.

2, gardening: knife saw, folding knife saw.

3, fitter: iron bow saw.

4. Handheld chainsaw: Handheld chainsaw and electric bow saw.

Above, Bian Xiao introduced the specifications of the manual saw blade for you. Including the detailed specifications and dimensions of fine serrations, medium serrations and coarse serrations, as well as the requirements of relevant laws and regulations on their dimensions and other performance requirements. We know that the original manual saw blade still has strict regulations. What kinds of hand saws are there? Bian Xiao also made a detailed introduction. Different types are used in different places. Consumers should be clear about their purpose before buying.
