Modified BDE Anticlastic Bracelet Die System to Set Stones

I have worked out an easy way to modify Lee's anticlastic bracelet system so a "platform" for a bezel set stone can be die formed simultaneously with the forming of the bracelet. I sliced a 3/16" "wafer" from a 0.5" diameter rod of delrin, rounded the edges, filed one side of the wafer to conform with the inside curvature of the anticlastic bracelet die and slid it into place between the die and a bracelet blank. The forming process creates a stone setting platform at the same time the bracelet is formed. The top pic shows the wafer set in place against the curvature of the die along with an inside view of the formed bracelet. The center pic shows an outside view of the bracelet with the platform. The bottom pic is a sterling bracelet which I textured in the hydraulic press with a "wire die system" I made leaving a plain surface in the center to set a stone. A system similar to the above discussion with the copper test bracelet was then used except the wafer was smaller and oval shaped to match the oval amethyst. I imagine multiple platforms could be placed in this manner but too many will use inside space and not leave enough room to get the urethane into place.
