a friend of mine has some vented disks for his car he wants to use. they're kinda grubby and rusty. anyone know anything about turning vented disks?? i know the stylus that is typically used is small. like a parting tool. even though this is a small surface area tool, can it still be used to turn a vented disk?? it doesnt make sense that it would catch but maybe it would. anyone know about this stuff?? just wondering.
