I just finished my first burner and it is a winner.It is based on the Oliver-upwind burner.Found this site about a week ago and thought this is so simple a caveman could do this.Corny aint it. It does work really well. Wish I had a camera ,sorry no pics. The only thing I changed is the flair . I used a 1 inch coupling with three set screws instead . The flame looks just like the one in the picture, nice and blue with a little orange around the edges . Now I have to build the forge. I'm thinking of using a freon tank but I do have a 10 inch diameter piece of pipe 12 inches long. Anybody have a suggestion.
