also had a question.....if i wanted to build a 4x2 melamine rack could i run the heat tape as one big piece or would i have to cut it individually? I was thinking about running 11 or 12" tape would that give me enough heat for 40" tubs?
You can do it either way. I prefer to use a single piece.
There the 5 shelf units from home depot, 24x36. They cost about $50. I just bought one last night and will be assembling a rack out of just one shelf instead of two. I'm counting down the hours until my work day is over and I can get to the good stuff!
