I'm just getting ready to start my first saber with the kits from the css, but I have a question that I haven't found answered in the tutorials, or anywhere else. After you run the el wire through the polyE, and put it in the polyc, do you put anything on the tip before the plastic end piece, like closing up the end of the polyE? Otherwise, wouldn't you be able to see the wire sticking in the polye if you looked at the tip? Thanks for any help.
