here is my newest one i have built. this was on test night. the overall size is 4' round, with a 3/8" thick bottom, the edges set higher and angle to the middle, in the center you have a 6" round 10" deep chute to act as a dump or charcoal holder to get the fire started if need be. there is a small handle that sticks about 2" out on the side that opens the chute to clean it out. i made trays that slide down the long poles and you are able to put them at any height above the fire. one tray can hold pots and pans the other holds a grill to hot dogs, hamburgers, steaks, etc.... i also put some tabs on it that hold a rotisserie so that you can adjust that accoding to height above the fire. when not cooking, you got a fire pit, tall enough to put your legs under and you can swing the trays out and they make a great beverage holder of you choice.
