Pendulum saw for wood with their own hands
What is the convenience of a pendulum wood saw?
The pendulum saw is an electric tool used to perform work on wood or metal. With the help of this device can accurately and quickly cut the workpiece into the desired number of pieces. The tool cuts by reciprocating movements of the saw blade on the wood part.
Pendulum wood saw with their own hands looks like a small machine, on which the sawing disc is fixed in a perpendicular position to the surface on the pendulum. Models vary in size depending on the power of the unit. With the help of the pendulum the cutting blade lowers or raises while cutting wood or iron.
Fitting saws
Mounting saws are a special type, they are used in construction and during repair work. They are characterized by high comfort and abundance.
But the construction of the assembly saw is greatly simplified. The pendulum mechanism makes cuts only at right angles, not being able to change degrees. Working disc of ordinary metals, without the application of hard-alloy coating.
Belt drive is used in such tools for convenience of use, it allows to make the work smoother, without jerks.
Working with such a tool has a number of features:
- Due to high torque the saw has to be held firmly and start smoothly to avoid sharp jolt.
- The workpiece must be secured before sawing.
- The place of sawing should be additionally cleaned, because in the process of work a burr is formed on the workpiece.

Cutting tool
Abrasive blades are used as cutting tool. Diameter of such a wheel depends on the model, its performance and working requirements of the owner.
Such saws are most often equipped with 12-diameter discs with 60 teeth. And the manufacturer of the discs does not necessarily have to be the same as the manufacturer of the tool. The main thing is that the dimensions of the circular saw blade must correspond to the recommendations in the technical documentation. To increase the strength and performance of the discs, the manufacturer usually applies carbide inserts on the tips of the teeth.
How these saw models work?
The tool can be categorized as a circular model. Cutting disc is installed on a special fixed frame, and the machine itself is powered from the electric network. The name “cut-off saw” is explained by the fact that the cutting wheel lowers down while cutting, and returns to the initial position after sawing is completed.
Powerful saw blade is able to cut not only wood or metal, but also faor, glass, plastic or tile. A blade removed from a circular saw can be used to cut wood.
Handmade mechanical metal saw
Since metal is very strong, not every saw can handle it.
The pendulum saw is popular because it does its job effectively, whether you bought it in a store or it’s homemade. If the price of a suitable saw does not suit you, it is possible to make the tool yourself.
To assemble the saw with your own hands is not difficult: in this article you will learn about its main functions and how to make it.

The blade of the circular saw, 150 mm long, is stretched with a metal frame in the shape of an arch. Saw is used for sawing curved surfaces in both solid wood and man-made wood materials.
Blades (15-17 tooth tips in 25 mm) are too narrow for sharpening and must be replaced if blunt or broken.
How a pendulum compound saw is constructed?
Pendulum wood saws are similar in principle to circular blade saws. The only difference between the two types of saws is that in pendulum saws the cutting blade moves during the operation by means of a pendulum device, while in the circular model the blade remains stationary.
This saw makes a precise, clean cut at a 90-degree angle. Some models are able to cut at different angles, with the saw blade tilted.
An abrasive saw blade can be used when cutting metal or hardwood. Different blade configurations are available for different applications. Universal circular blades are also made to work with any part material.
All saws are equipped with safety features that reduce the risk of damage from the rapidly rotating saw blade.
The main disadvantages of these cut-off saws:
- Sawing by hand requires a lot of effort and fatigue;
- the cut-off model, like the jigsaw mechanism, can cut a limited thickness of workpiece;
- The device has a small capacity, so it is used as an accessory or for domestic purposes.

Any pendulum saw, regardless of whether it is handmade or made by a well-known manufacturer, has the following units in its design:
- frame;
- powerful electric motor;
- saw blade;
- The blade guard;
- return mechanism;
- clamp for clamping the product to be sawed.
Composition of pendulum saw assemblies
The massive, heavy saw frame is made of cast metal to ensure the stability of the tool during operation. It carries all the other components of the saw. Above all, it is a pendulum lever, on which is mounted a powerful electric motor, an extended shaft with grooves and screw threads for mounting the saw blade. The arm has a spring mechanism that resets it to its original position after the cut is completed.
The handle of the lever has a trigger for the saw. For ease of use, there’s an added latch on the button that locks the tool shutoff when the button is released. Cutting tool is fully enclosed by a protective guard to protect a person from injury while working. On some models manufacturers install two guards. one stationary, the second. sliding, completely covering the cutting zone.
Unit with description of assemblies
Pendulum metal saw is not only used when working with metal products. It can work with wood, ceramics, plastic. But for cutting other materials a different blade must be used. Various cutting attachments can be supplied as a kit, but can also be sold retail.
Two-piece clamping base for clamping the workpiece to be sawed is attached to the frame. The first part is pivotable, which can pivot by up to 45°. It has a pointer and a scale, graduated. The second part is a screw-adjustable nip. The clamping jaw on the second part is hinged, which allows you to firmly fix the part at any angle to the front of the product, ensuring a precise cut at a chosen angle.

Working with such a tool has a number of features:

- Workpiece must be secured before sawing.
- The sawing area should be additionally deburred, because a burr will form on the workpiece in the process.
