A machine or device for forming tubes or the like includes one or more cables or other elongated flexible members. An expanding forming device is positioned at an end of the cables, and the cables are inserted into a tube that is to be formed. The expanding device expands outwardly, and tension is placed on the cables to pull the cables through the tubes. This causes the tubes to be permanently deformed outwardly to a larger outer diameter.
