I was at my grandparents the other day and my grandma was showing me some things I can use for enclosers and one thing she showed me was an old locker, It came from University of TN in the 70's. Its made out of plywood and each locker measures 34" 1/2 long, 21" deep and 8"1/2 tall and it has 9 lockers on it. I was thinking about removeing the doors and cutting a window in each door and putting a piece of plexi-glass into the window. My questions are does anyone think this would work and how should it be heated? Its going into a heated room if that helps and would this be good for balls?
