Here a picture of my fire pit. Used a clamp on dual spacer for the ring. Supposed to cement the bricks around it but just have never thought it important enough to do. I can adjust the height of the cooking rack and swing it 360° around. Simple and not fancy looking but we sure enjoy what little time we do spent around it or cooking on it.

My fajita disk setting in the fire to clean the rust as I had forgot it and let it set outside.
