The primary processing of wooden materials often consists in cutting them. Several types of tools can be used for execution - from manual to electric models. The most effective is a stationary circular saw, which you can do yourself.
Circular saw design
At the first stage, it is necessary to understand the design features, to determine the optimal manufacturing scheme. It directly depends on the characteristics of the work performed, the dimensions of the workpiece, the type of wood. Only after that can a circular saw be made with your own hands.
The main component of the saw is a disk, on the end surface of which the cutting teeth are located. They can differ not only in geometric dimensions, but also in the angle of inclination relative to the plane of the disk. To perform cuts, an electric motor is provided in the design. It can be connected to the disc directly (through a shaft) or with the help of a drive torque transmission system. This tool is designed to perform longitudinal and transverse cuts, in some models it is possible to make angular, relative to the plane of the workpiece.
Before you make a circular saw with your own hands, you should choose the depth of processing. To do this, you need to familiarize yourself with the classification of equipment:
- small - from 40 to 46 mm;
- medium - from 55 to 55 mm;
- large - from 65 to 70 mm;
- professional - from 65 to 140 mm.
For housework, it is enough to choose a model with a small or medium cutting depth. If complex processing of materials is necessary, a hand-held circular saw is required. To make vertical cuts, you can make a homemade sawmill.
For woodworking, it is necessary to choose discs with a positive sharpening angle. Otherwise, the wood fibers will not be cut, but torn apart.
Table design for a circular saw
The main component of the future design is a do-it-yourself table. It will house the power unit, cutting tool, control unit and additional components to get the job done.
There are two fundamentally different schemes for designing a table. In the first case, it is designed to work with a hand saw. The main task of the support frame is to fix the workpiece and the ability to change the direction of the cuts. Most often, wooden components are used to make a table with their own hands - chipboard sheets, slats and timber.
The sawmill is one of the varieties of circular saws. The difference lies in the lower location of the disc. In this case, the table acts as a bed. It houses the power unit, there is a disk attachment unit, as well as a control system.
During design, the following points must be considered:
- motor power. For housework, it is enough to choose a model with a specific power of up to 800 W;
- cutting depth. Depends on the geometric parameters of the disk;
- rotation frequency. To form an even color, this characteristic must be at least 1600 rpm;
- location of the control unit. It should be as far away from the disk as possible.
The dimensions of the homemade design depend on the dimensions of the workpieces. For the manufacture of a manual sawmill, it is recommended to use a metal sheet as a countertop. Additionally, stiffeners are mounted at its base.
When choosing a factory saw model for completing a do-it-yourself table, you should provide for the possibility of fastening at the bottom of the tabletop. To do this, you will need to make an additional transitional mounting block.
Making a circular saw with your own hands
Drawing up a manufacturing scheme depends on the actual availability of consumables. Most attention should be paid to the design of the table. In addition to functionality, it must be stable, withstand maximum pressure without changing its position.
First you need to make a countertop with your own hands. To do this, markup is performed on the sheet material. It is best to take a tool and mark the cutouts according to its dimensions. With the help of a milling cutter, a recess is made for mounting the tool. Then you need to install additional components:
- workpiece stop. This is a wooden rail that is attached to the tabletop. Its position can be changed relative to the disk;
- grooves for emphasis. They are milled on the surface of the countertop;
- yardstick. It is installed at the leading edge of the disk. It is necessary for the formation of blanks of a certain width and length;
- clamps. They are an additional component. With their help, the part is rigidly fixed on the table for processing its surface with a hand tool.
After that, according to the actual dimensions of the tabletop, it is necessary to make support legs. To do this, you can use wooden bars 40 * 40 mm or steel corners. To improve stability, stiffeners are attached between the legs. The saw control unit must be located at the workplace. RCDs and fuses must be installed in case the maximum load of the electric motor is exceeded.
Checking the performance of a do-it-yourself design must be carried out with a gradual increase in load. Small workpieces are processed first, and then large parts.
