[QUOTE="shivan, post: 183050, member: 194"] If they are already well river worn and you are happy with the shape you may be able to get away with just a polish, but I would still look at, at least one prepolish. Each polish stage will depend on what you want to achieve with your rocks. If there are lots of rough edges it will take longer than rounded rocks. Harder rocks like quartz will take longer than softer rocks. I normally leave the rocks for at least 1-2 weeks per stage. For my tumbler I fill it 3/4 with rocks/medium then add about 2 tablespoons if using cerium in polish, 2-3 for earlier stages. The medium I got for my tumbler is small hollow plastic pellets, but even small pebbles can be used. When using medium like the hollow plastic pellets, if you want to re-use them, remember what grit you used them with as if used with a different stage, it can contaminate. [/QUOTE]
