How Do You Make Air Duct?

The term 'air duct' describes a kind of equipment that is made of sheet metal and is used to carry heated or cool air to the area you want. If you want to make it yourself, it is quite a complex process and requires a lot of effort. But if you are still hell-bent on making it, we can suggest you a method.
       
What you will have to do is to take a metal sheet that is so thin that you can mould it yourself. After taking the sheet you should take pliers and with the help of them, you should give it a shape as you give to a duct. Then you can fit it at the place you want to and then can direct the air to the room where you want it to be.
