Maybe you've seen those wrought-iron cooking setups that the cowboys use to hang their Dutch Ovens and other cast-iron over the camp fire. A search on the Internet will reveal that they tend to be a bit expensive if not outright obscene in terms of cost.

In addition, you'll need two T-connectors (3/4 inch by 3/4 inch by 1/2 inch), perhaps 4 cheap 5/16ths carabiners or S-hooks, and 2 lengths of 2-foot x 1/4 inch link chain. See the photograph that illustrates all of these components. Total cost for all of these was less than $30.
