How heavy was it? Did it seem to roll/change sides easily?
It rolled great. It wasn't as heavy as I wanted it to be, since I could only get 1/16in sheet metal on short notice. I wanted to build it with 1/8in metal plate to give it a bit more weight, though still since it was made of steel, it had some decent weight to it. I could feel the vibration of it rolling on the convention floor through the stage I was sitting on, so I suppose it was decent enough.
I suppose I could actually weigh it when I get home to find out, but my guess is around 4 pounds.
