Jayne Redman® Slider Clamps for Rotational WorkRing System Jayne’s Slider Clamps are designed to securely hold materials of any size, shape, or thickness within the 4.5” WorkRing of the Jayne Redman® Rotational WorkRing System. These clamps also work with the 2.5” Large Ring Circle Clamp of the Swanstrom SawPlate System (available through Micro-Tools). Effortless, Secure Workholding Eliminate muscle fatigue by allowing the WorkRing System to securely grip metal, wood, plastic, or other materials while you saw, carve, texture, engrave, set stones, or use other metalsmithing techniques. Plastic and stainless-steel thumb screws or Phillips head screws hold the material in place. The slotted design allows the clamp to slide freely between screws, enabling easy adjustment for proper holding distance. Designed by Experts The Jayne Redman® Rotational WorkRing System was created by Tim Sheriff of Swanstrom Tools USA in collaboration with Jeweler-Educator Jayne Redman. ??
