This exercise was to try my hand at hammer forming. The goal was to build a welding helmet that combined an industrial look with the technology of an auto darkening lens. I chose to use old school mechanical fasteners (rivets) to keep the steampunk aesthetic. I found the aluminum pots and pans at a local salvage yard and the head gear was scrapped from an old helmet. The cake cover was just about the right size and a toaster oven tray made a good lens frame. After a few thousand hammer strikes and a bit of riveting, this is what I ended up with.
