I found one at a salvage yard. They had taken a demolished high tension utility pole and cut it into 16" pieces. The wall is about 3/8" and my section is about 60" across. Weighs around 250lbs. I then dug a hole and rolled the piece into the hole. Works great and I really like having the fire down in the ground. Air draw does not appear to be an issue.
