If the ball needs to be thicker than all you need is super glue. Before you start be prepared. Have a rag with you for any dripping and wear latex gloves. Wearing protective eye equipment is not a bad idea either. Apply it lightly and MAKE SURE you continuously move the joint around untill the glue dries. Move it in every possible direction the joint will go. If you don't do that you have your self a solid arm that won't move. Keep applying little by little untill it's where you wan it to be. Have fun and don't hurt your self!
