I've been making a lot of silver cuff bracelets and hand polishing them is quite hard work. I have a tumbler which helps finish them off but I have to polish the stamp bruises off them before I tumble them so was wondering about getting a polishing motor..

For eg, I saw this one on Cooksongold but don't know what I'm looking for really and could do with some advice http://www.cooksongold.com/Jewellery...prcode-999-AX8

Also, I don't know much about using polishing compounds etc, what and how do you use them? And how do you clean any residue off the piece afterwards?

Any advice appreciated.
