i haven't figured out how i'm going to cut the groove yet. my father is a carpenter so i'll have to ask him and see if he has any ideas on how to do it.
It looks like it is possible to use a router on PVC sheets. Now the question is, how wide of heat tape do I need to buy? I know i can use a plunge router to route out the track in my shelves for the tape.... But how wide?
