I have no idea. Current plan is to build 2 of them. 1 is going to a guy I work, He doesn't want to spend much money on it and he wants it cheap as I can make it. There was one I was seen on this forum were a guy used large angle iron and made 4 legs when added a top and great, Thinking what would be super easy to lay out and keep the cost down for the guy at work. Then build a half cooking rack that lays on one side of the fire pit
