I spent the afternoon playing with ways to finish a cast bronze anchor. It would appear that a medium stiff wire brush wheel on a 6 inch bench grinder does a pretty good job of getting rid of the casting coating. Flash if present, needs to be ground away first. Brushing is then followed by a cloth buffing wheel using buffing compound available at Sears. It's important to get any imperfections ground away before the wire brush wheel, or you'll have polished imperfections. I use a "roto zip" tool with a carbide burr for any big metal removal and a common dermal tool with smaller carbide burrs for detail grinding. The dermal tool with a small white polishing disc does well on polishing tiny spaces. There are lots of recipes out there on how to keep you copper things shiny. Linseed oil is one and is cheap.
