So I suppose I should have clarified. I agree that structurally the tube concept is overkill. It adds support the rail doesn't really need. We did this because we felt that just pressing the bearings into the rail would cause them to fall out easily. Is that not the case? Does 1/8" wall easily support bearings without them falling out? Because in my experience that hasn't happened. If someone could tell me how to put the bearings in without them falling out I would be happy to learn. (Because those tubes really sucked to put in...)
