I've found a piece of 6 inch diameter steel pipe, three-eighths of an inch thick. I am thinking about welding a piece of half inch flat steel ,eighteen inches square,to the lower end and bolting this to a cubic yard of concrete in the ground. As to the pipes length, it can be cut any length I need.

What diameter of pier would be proper, if I use reinforced concrete to support a c6r-gt,5 to 6 feet above ground and 3 feet buried? My yard has more aggregate in it than Sea-Tac International's runways.
