To create a small machine capable of sawing iron and wood, you need to find a 12-volt engine. Due to the voltage, the saw will be able to work from a car battery, which is very convenient when there is no power supply. For the installation of cutting wheels for metal and saws for wood, you need to install a special adapter with standard landing dimensions on the motor shaft. When the electrical part is ready, the bed with the lowering mechanism and the spring for return is mounted.
The universal saw is a very useful tool because of its size, power source and the interchangeability of abrasive and detachable nozzles, this craft is useful in construction and in the country.
