This was done a few years ago so I don't remember exactly how long it took. It was done by myself and a JW. He did all the pipe you see in the photos. There is something in the pics I thought someone might pick up on and bust my chops for but it's probably not obvious because of the resolution of the pics. I have the answer but lets keep it interesting and see if someone can pick it out!
(Hint: The wall you see is 18 Gage steel studs and 5/8 drywall)
