When I first starting working copper, I over clad with copper, a 5 foot by 2.5 foot sculpted wood form, with a granite base. So that when I was finished, I had a piece of art that weighted 210 pounds. Don Q was my attempt to lighten the finished project. After applying the copper to the finished form, I removed it and reassembled it using copper rivets. It went from 24 pounds to 4 pounds. After I mounted it to a sandstone rock that I picked up in Arizona, the weight was back.
I really didn’t carve this with the intent of making this look like a waist coat when finished, but what can I say … it just does.
