A table 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 a lot of time and money for this. The machine can be made from improvised materials.
First of all, the base of the saw should be made. It must be stable and durable. For the construction of the case, you can use wooden blocks, the cross section of which is 80 * 60 cm. The frame can also be sheathed with wood materials. To connect the elements, it is better to use self-tapping screws or large bolts. In this case, it is necessary to make sure that the nut does not unscrew on its own as a result of vibration.
Do-it-yourself circular saw is built quickly enough. After the enclosure has been handed over, a suitable countertop should be cut out. You can use thick plywood for this. Under the tabletop, the main mechanism will be located. It has several nodes: an electric motor, a spindle and a disk.
Do-it-yourself circular saw 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 capabilities your electrical network has. If you are not connected to a three-phase line, then you will need a motor designed for standard power: 4-6 kW / h with a voltage of 220V. It can provide a disk rotation speed of about 3,500 rpm. Such a machine is suitable for cutting boards whose thickness is 70 mm.
Do-it-yourself circular saw is made according to a certain scheme. If the motor is selected and the base is made, proceed to the next step: manufacturing the spindle. It is a housing with bearings and a shaft. It is on it that the disk will spin. As such a mechanism, you can use a bicycle pedal assembly. Instead of a standard sprocket, you can install an element from the engine.
Now select the cutting component. The diameter of the disc should correspond to the size of your machine and the thickness of the processed material. The standard value is 12-13 cm. The main part of the disk is inside the machine. Only a small part of it is visible on the surface. The disk is put on a shaft attached to the engine.
Thus, you will get a mini circular saw that you can install on the street or in the garage. She will be able to satisfy all your household needs. If the amount of processed material is very large, then a more powerful unit should be made. And yet, the engine must constantly be blown with cold air so that it does not overheat.
As you can see, a do-it-yourself circular saw is done quickly. You will not need to spend a lot of money on its construction. The main thing is that you must adhere to the mandatory safety rules both in the manufacture and in the use of the unit. During assembly of the circular saw, check that all fasteners are tightened tightly, as poor connections can lead to serious consequences. Follow the instructions and good luck with your endeavors!
