I realize they do two different things! I was just stating there is a gap; it would be nice to have box tubing “roller” that could roll a circle smaller than 12-inches without a segmented look. I don’t see why you couldn’t roll a piece of 1/8-inch round stock in a rig roller and tack it in the center of the upper roller of the tubing roller, and do the same thing as the AZ bender. As AZ had stated you have to force the wall of the box tube inside it’s self to achieve a smooth radius.
