Got a friend who was shopping for burners for a forge, so I offered to build him one. I don't have a gas forge so I thought it was time to make a pattern. I like black walnut. Lineup dowels drilled and nozzle covering one. Paper line split Dowels made Painted and lettering added Two cast MIG tip installed. Manifold is turned far enough for tip to clear air holes. First burner finished. Tube is 1" 0.049 304 SS (what I had) with two 3/4" air holes. Fire time!! Nozzle has no step, just the 0.049 wall thickness, I need to make a larger step nozzle.
