I noticed in one of the tutorials a peice of pvc pipe. Can you use it as a mold? If so will the pr release from the mold without any release agent?

yes you can and yes it will. PR shrinks when cured. You may want to try the round ice trays from Walmart...they make cylindrical shaped sticks of ice for dropping into water and soda bottles. They work really nice but not for the very largest of our pens.
Do a good turn daily!
