During the execution of repair and construction work, it is often necessary to cut the material at different angles. You can do this with a stouch. But the choice of corners in this instrument is extremely limited.
Forest saw device.
Under any angle with great accuracy, you can perform cut, using a special tracing saw. With the help of this unit make window frames, door and window boxes. How to choose a tracing drink so that she worked qualitatively and for a long time?

General information about the ending saw
Fantasy saw, which in the people has the name of the ending, is used for cutting blanks from wood (drawn No. 1). But sometimes it saw plastic, laminate and even metal. This tool is easily, very accurately and at high speed cuts the material at a given angle.
Image 1. Furious saw is used for cutting wooden blanks.
This ability has found its use not only in construction, but also in the production of furniture. Similar tools are often used in the manufacture of plastic windows.
Fantasy saw consists of a motor equipped with a gearbox, and a working disk. They are installed on the basis along with the activation button. These are the main details and nodes. The main load when working is experiencing a cutting disk (ed. No. 2). For its manufacture, high-quality heavy-duty materials are used.
The engine can be used collector or asynchronous. Asynchronous makes less noise and serves much longer. The collector does not have these advantages, but it does not require maintenance and special attention to yourself. Most often, it is placed on the basis of the right side of the disk, sometimes it is put in the back of the saw.

Rotation from the engine to the disk is transmitted by means of a toothed or belt transmission. The gear transmission does not slip when the load. The belt makes less noise and vibration, prolongs the service life of the engine. But the belt itself is gradually subjected to wear and requires periodic replacement. In some cases, at high loads, it can simply fly from pulleys.

Tool selection criteria
How to choose a permeable saw to serve for a long time and proper? When choosing tortowk, the following points should be considered:
When choosing a permeaker saw, it is recommended to use a tool with a disk, the diameter of which is 20 cm.
- The purpose of acquiring the tool. For infrequent use, a tracing saw that performs standard functions is suitable. For more frequent and complex works, it makes sense to acquire a professional version.
- Security. Be sure to be a casing, fully closing the work disk. During work, it is removed. The saw should be equipped with an automatic shutdown system if the disk strokes. There must also be a system of quick and durable billet on the table. The safest saws produce firms: Corvette, Makita, Bosch, DeWalt, Metabo, Hitachi.
- Overall dimensions and weight of the instrument. Too heavy saw will make it difficult to work. The operator will experience fatigue.
- Ergonomic. Fantasy saw should provide maximum amenities when performing work.
- Diameter of the work disk. It is recommended to select a tool with a disk from 20 cm. The maximum diameter is specified in the instructions for the engine. Discs with thin cuts and wavy lines make less noise. The seating hole is a diameter of 25 or 30 mm. Larger teeth will give a rough cut. They can not be purely cutting laminated products, as well as blanks covered with expensive varnishes and paints. For their processing requires a disk with small teeth. Small-grained disc can be cut even aluminum blanks.
- Width and depth of the recent.
- Quality of base and swivel block. The most durable fabrics are made of magnesium alloys and aluminum.
- Additional highlighting of the working area makes it possible to perform work in conditions of weak light.
- Fantasy saw Some manufacturers are equipped with an electronic system that supports the turnover of the saw disk at constant values, regardless of the load.
- The speed of rotation of the saw disk. What it is higher, the cleaner turns out. The function of adjusting the number of revolutions allows you to cut a tree, plastic, aluminum, plexiglass, cement-chip materials.

The advantages of some models drank
Sanding "Makita LS 1040" saws, a compact size and low weight equal to 11 kg.

Slipping the blanks with a thickness of up to 95 mm at an angle of 90 degrees, up to 67 mm at an angle of 45 degrees. For the processing of long blanks, the installation of special stops into the holes of the aluminum bed is provided.
The swivel mechanism is easy to stop and locks out and fixed with the screw mechanism. It has a special fixation with a characteristic cluster when installing the angles of 15, 22.5, 30, 45 degrees. The disc can be tilted vertically up to 45 degrees. The quality of the device is very high, the cut is accurate and clean.
The protective casing automatically shows the cutting disc when it is lowered to the workpiece. It is made of a transparent high strength material. There is a device to protect the disk from the jam. The smooth start system accelerates the disk without jerks. For a set of complete revolutions, he need 2 seconds. The tracing saw of this model is equipped with an electrodynamic brake, which quickly and smoothly stops the disk after turning off the engine.
