I think that when you twist the tray it is hard to reach some areas of the bundle with the sandpaper. Maybe some don't get touched at all. That seemed to be happening when I was polishing the sci-fis. One side was polished but the other was not when I was twisting the tray. I might have reached those fibers more readily by reversing the spin direction and the twist direction, but I did not want to do that because it would also change the direction of the striations. | I think that when you twist the tray it is hard to reach some areas of the bundle with the sandpaper.
