Circular saw with own hands: features of the construction

A table circular saw is the dream of every owner. Such a tool can be bought in the technical department of the shopping center. However, you can do it yourself. You do not need to spend much time and money for this. The machine can be made from improvised materials.

First of all, it is necessary to make the basis of the saw. It must be stable and strong. For the construction of the case you can use wooden bars, the cross-section of which is 80 * 60 cm. The frame can also be sewed with wood materials. It is better to use self-tapping screws or large bolts for connecting the elements. Thus it is necessary to make so that the nut is not untwisted independently as a result of vibration.

A circular saw with its own hands is being built fast enough. After the body is delivered, cut the countertop of suitable dimensions. For this, you can use thick plywood. Under the top and will be located the main mechanism. It has several nodes: an electric motor, a spindle and a disk.

A circular saw with its own hands provides for the selection of a sufficiently powerful power source. It depends on how big the installation will be, what kind of performance you need, and also what possibilities your electrical network has. If you are not connected to a three-phase line, then you will need a motor designed for a standard power: 4-6 kW / h with a voltage in the 220V network. It can provide a disk rotation speed of about 3500 rpm. Such a machine is suitable for cutting a board, the thickness of which is 70 mm.

A circular saw with its own hands is made according to a certain pattern. If the engine is selected and the base is made, proceed to the next step: making the spindle. It is a body with bearings and shaft. It is on it that the disk will rotate. As such a mechanism, you can use a bicycle pedal assembly. Instead of the standard sprocket, you can install the element from the engine.

Now select the cutting component. The diameter of the disc must match the dimensions of your machine and the thickness of the material being processed. The standard value is 12-13 cm. The main part of the disk is inside the machine. On the surface you can see only a small part of it. The disk is put on the shaft attached to the engine.

Thus, you will have a mini circular saw that you can install on the street or in the garage. It can satisfy all your household needs. If the amount of material being processed is very large, then a more powerful unit should be made. And more, the engine should be constantly blown with cold air, so that it does not overheat.

As you can see, a circular saw with its own hands is done quickly. You do not need to spend a lot of money on its construction. The main thing is to adhere to the mandatory safety rules both in the manufacture and when using the unit. When assembling the circular, check that all fasteners are tightened, as bad connections can lead to severe consequences. Follow the instructions, and good luck with your endeavors!
