Why do some yoyos have vibe, even if they don't have any visual damage? Is it that the metal is denser in some areas, or the machining makes an elipse and not a circle?
Machine error, human error, material problem....any number of things.
Something to note: machining a return top does not remove the human element...it's as much of an art as it is a science. Which is why some machine shops get it (One Drop) and other's don't (the ones we used in Canada).
