A contractor had me build an artsy surround for a zero clearance fireplace. The homeowner liked to fish so salmon made perfect sense. I started with a 1”x4”x16” piece of mild steel. With my Nazel #1 power hammer, I hammered one end (the head) down to a blunt point. This created a cold shut that began to form the mouth. The head is rounded with a hand hammer and the lips and eyes were punched or chiseled. The tail is formed next and then the body is widened and lengthened simultaneously to an acceptable scale. The fin areas were drawn out further except where I had to weld them on.
