Starting with a template
for the base and the collar, I then used a 16" acrylic globe and cut holes into it for the eyes. The base is made with EVA foam.
The eyes were covered by clear spice-tin tops.
The gauges were made of spice tins and printed meters created in Illustrator/Photoshop.
Air hoses are made from wire-loom - (cable covers), painted with a aluminum paint.
Everything was painted with a flat black and then painted with a wax copper or gold depending on the piece.
Another layer of Metal Masters Copper Paint was added to the copper layers and then patina sprayed on. (The patina solution creates a real patina on the copper in a short time.)
Gloves are rubber blasting gloves painted, collared with EVA foam.
Boots are oversized Sketchers, with EVA foam and rope.
