I'm building a new rack here shortly and I'm trying to figure out how I want to install the heat tape. Since I plan on enclosing the sides and possibly the back I think I want to try routing the shelves and sides so I can just run the heat tape through the rack. I've never done any routing so I was wondering if anybody had any advice or any pictures and videos. Also what is a cheap tool I can use, all I really own is basic tools and a power drill!
