Making polished wheels look machined?

[aggie91]

I have seen the scotch brite done to a polished wheel, it just looked dull, not really like a machined wheel. To get the machined look, I would think you would need to do it with 120-180 grit paper. Getting all the sanding scratches to stay true to the wheel would be hard imo if it is not done on a lathe or something to spin the wheel at a constant speed...
