Re: Cutting geodes
Doug, My method is to replace both wooden contact surfaces of vice jaws with replacements made of 3/4 inch plywood. The ends closest to the blade are elongated to extend out past metal vice jaw about 3 inches past saw blade and new "jaws" are tall enough so blade cutting through leaves about 3 inches of wood untouched above the cut. Let the blade cut through new wooden vice jaws far enough to create a cut where the blade will always pass through. A round geode can now be positioned in the new vice jaws in any direction you prefer where the blade can pass through the exact center of even the roundest geode. While positioning you can rotate the geode in the correct axis to take advantage of any flat surface, but usually just the rough outer surface of the geode biting into the wood will hold it just fine with normal pressure on the vice jaws. I cut nothing but geodes and this works very well. Regards Ron Shearer, Loveland, Colo.
