Perchchaser,
Wrap about 4 or 5 coils onto the end of your rod tip so the majority of the spring extends out past the last guide. You may have to stretch the spring wire close to where it goes past the last guide so that it fits properly. You can use heat shrink tape, hot glue, or even electrical tape to secure it to the rod tip. You then run your fishing line through the last guide then through the spring so that your fishing line hangs out of the spring. Hope this helps.
