Mould precision parts - turn sugru on a drill bit

With my satellite antenna taken apart by a rampant car wash and us not using satellite radio anyway, I replaced the bare antenna with a sugru covered screw. I placed the screw in a drill, applied sugru, and spun it while forming with soap covered fingers, as if on a potter’s wheel. I also used the turning drill to carve a concave shape for the base with an exacto knife. It was amazing!
