Hi all as part of a mini project into specialist techniques I carved a wax ring and had it electroformed. It was a very detailed carving and when it came back it was very bulky and is now too small to fit. I think 1mm of metal was formed over the ring and a lot of detail i carved has disappeared. Now I just want to know will I be able to restore the delicacy of the ring by filing back (its copper) or will I damage it by using files on it? The wax remains inside. I hope I can 'restore' it as I would like to silver and gold plate it.
