Compressor com motor de geladeira

In this video I show my compressor, which was made from scrap parts and was very cheap: cylinder 30 reais, pressure switch 100 reais, pressure gauge 1 real, refrigerator motor 10 reais, safety valve 25 reais, a total of 166 reais. However, making a very useful tool from parts that came from the trash is priceless!! Haha
