[QUOTE="Dughug, post: 50365, member: 157"] G'day diggerdave, your vibrator that you use for shells will work well with rocks. Use a silicon carbide grit start at no finer than 220 grade (coarser grits will eat your barrel) after about a week your stones should be ready to progress to the next finer grade grit a couple days to a week then on to polish. You can get the grit and polish powder from any gemshop or supplier e.g. Shelleys, Aussie Sapphire, Gemcuts, Rubyvale Cut & Slice to name a few - google them & have a look at their site. You can also get the grit on Ebay. [/QUOTE]
