I have recently pulled up the carpet in my sons room and wanted to refinish the wood floors. His room is 9'x9' and I was wondering if anyone ever tried to so a floor with a hand belt sander? I am just trying to get off cheap because over the summer I am doing his room, my room and maybe the living room and hallway. I don't want to spend the money for rentals every time I want to sand the floor. My living room may be the only room I have no choice because of size.
