That hourglass buff would almost totally eliminate the problem of your buff grabbing the tubing. Looks like a perfect thing for tubing. I question whether a drill would turn it fast enough to do much on stainless though, the effective diameter appears to be only a few inches. I would think you would want to turn that thing at about 5 or 6 thousand. But then, why not try it with a drill? I can't imagine your rails have deep scratches, unless they got up against a concrete wall somewhere, so a drill might work fine. Stainless is hard stuff though. (I really hate it; that is until it's all done and polished. Then it's simply wonderful, and worth all the effort.)
