Not sure exactly what kind of outside stove you have that needs a leg, but if it's a grill of some kind, I made one once out of an old auto wheel rim, with a steel pole welded to the grill, which could be inserted into the center of the rim. I welded a short sleeve into the rim, so that the grill pole just slid down into it, and was removable for travel. Just a thought.
