This took me 3 months to complete. I started with small pieces of 18-gauge sheet metal and hammered them into the right shape, then migged them together and ground as I created the body.
The dorsal fins were created using welding rods cut in half and then migged on top of shaped 24-gauge sheet metal. I used large metal ball bearings for the eyes - cut them in half on my chop saw.
I used oil paint for the finish. None of the patinas I used looked even decent, so I kept grinding them down until I started to grind through the metal. Good thing the last finish worked. Used Eastwood Diamondcote for the final. It's sealed it very well.
The stone that I used as the base was one that I backpacked out of a Canadian lake years ago.
The sculpture is 53" high, 28" long.
