Does hammering copper sheet reduce its size?
I am a sculptor applying 26 guage, 16 oz, copper sheet to 3/8" stainless steel plate forms. The copper and the stainless will be cut in the same shape of human forms. I will then hammer texture to the copper sheet before adhering it with adhesive and rivets to the stainless. How much will the copper forms draw up in size? Should I cut the copper a bit larger than the stainless to allow for the contraction?
