Steampunk Arm Final

"The first is a device I call the Scald. It's like an iron sphere that fits over the hand like a glove (padded and insulated on the inside). The sphere has holes in it that vent high-temperature steam outwards, supplied by several pipes which strap to the back of the arm, leading to a shoulder or upper-arm mounted boiler tank. Again, there's no need to draw it being worn by someone, the picture just needs to focus on the device"
