No problem at all! I love hearing about people building and using this rack. I'm definitely open to suggestions, additions, etch! When I built the second rack I took advice from people who posted on here about weaving the flex watt through the rack. Definitely the way to go.
I haven't put anything on the sides, I just heat the room to 75 degrees and leave it at that. I have looked into insulation as the sides, like the aluminum stuff, but it's pricey and thus far I don't need it.
I used a miter saw to cut the poles. You can take the longer cheaper route and use a hand saw. It doesn't take much to cut through it.
