I have used one flower pot and 6 bicycle tires spokes to make the barbeque. We cut a big square window to set fire on charcoal. Some big holes are there for passing air. Few small holes were made using a drilling machine to fit the spokes. It’s very easy to make and inexpensive. I spent hardly one dollar. Very easy to use and set fire to charcoal can be done quickly and easily using some new papers.
