Plow disk made into a wok

Several years ago at a friends house in New Mexico he had a Wok that he used to cook outdoors for a large group of us. The wok was made from an old cast iron plow disk with the hole welded shut and horseshoe handles welded on. It was great. When we left he gave us all the parts we needed to make our own Wok. We took it to a welder and Carol used it a couple times outdoors. Now that she has a gas stove she wanted to try it out again. It worked great.
