Hello friends ! Today I will cast a Japanese katana sword from an engine piston. They sent me four pistons from the engine . They are made of aluminum and there are also steel and brass parts . I will melt the aluminum and pour the molten metal into a sand mold and leave the steel and brass . This is my most difficult project at the moment . I did the katana for a whole week , many of the works I did for the first time . Enjoy your viewing ! #making katana #casting #hotmetal Making a katana out of the piston .Aluminium casting Like, Subscribe & SHARE the video also comment your opinions. Hope you Enjoyed the Video.
