What is the easiest and fastest way to sand and polish out embossed and incised bronze or brass type metal to give a smooth, mirror finish, such as machining pre-1982 pennies to smooth copper disk to be used as a heat spreader?
I'm mainly interested in pure copper, brass, nickel silver, and maybe aluminum.
Coarse grit paper takes away the incision fast, but it leaves streaks that takes a long time to polish out, so I would use finer paper, but it takes a long time to take out the incision/embossing.
