My "almost free" sort of portable fire pit. The 13" warped steel wheel and grill were rescued from a back road trash pile, the rocks were picked up here and there over a 5-6 months, I got the aluminum skillet ( with holes now) for a couple dollars at Goodwill. The 10" carbon steel and #2 potjie are mine. Pile the wheel full of rocks thru the center filling it up... You might have to rearrange a few rocks to "build" a stable surface for your fire pan I tried this with both the # 2 and #3 and it worked with both.. Or you can pull the fire pan and put the fire directly in the wheel while still leaving no burn mark on the ground... and use a flat bottom pan or Dutch oven. This will be helpful where there are not established fire rings and such and you can take it with you when you leave, use it again.
