No like a boom you use to make some blow up
I hope what you mean is how to make a camera boom. You can make a camera boom out of a number of things like wood planks or even junk that you find around your garage or around the bin. You just need to know the mechanism and go with you camera requirements. You must know a few things before you start off, make sure the camera end is 3 to 4 times longer than the boom pole. You have to make a cradle with holds the boom around 2.5 to 3.5 feet from one end of the pole. Try not to use a video head as they move a lot, use Monster balls heads instead, they work very well. It is a wise idea to mount your boom on something else, bigger the boom, the farther you will want to go from the tripod.
