[QUOTE="Keen Ken, post: 314415, member: 211"] Just take care cutting the Thunder Eggs. If you use a saw that is not cooled you may fracture the centre. Also a dry saw will tend to over heat the surface of the cut resulting in thousands of tiny surface fractures that will be nearly impossible to get out if you should decide to polish them on a flat lap. Lapidary clubs are the best and safest option. The geode is best held in a secure rock vice, free handing with an angle grinder is fraught with danger. Hope this helps [/QUOTE]
