I am making my first vulcanized rubber mold today and I ran into a slight problem, I was hoping someone may have an answer!
I am making a silicone rubber mold of a silver wishbone, so I can eventually cast it into gold. I want to attach a sprue and rod to it so it comes out in the mold. Are there any suggestions how I should attach it to the silver wishbone? I don’t want to solder a rod to it because the piece is not mine and I don’t want to damage the original at all. Do I use wax? If so, how do I properly attach the wax to the metal so it will stay?
Thanks! I can use all the help I can get
