I have both types of Ruth Niles bottle stopper mandrels . I am having a big problem getting the stopper to release from the mandrel when I am finished. Today I turned two stoppers and both of them are stuck on the mandrels and I can't get them off no matter what I do. I am ready to cut them off. I hate to ruin them but I may not have any choice. Has this ever happened to anyone else and if so can you please give me a solution for releasing them from the mandrel.
