I can see that, Khatfull, and the abrasive balls look very handy. I guess my only concern, even with a 4 inch ball cut down, would be the effect on adjacent surfaces. ie; the possibility of rounding over adjacent edges and/or losing definition where you might not want to. For instance, in polishing the flute in a Nuovo Record crank arm, where you want to polish the flute itself but not the corresponding edges where the flute meets the flat face of the arm. I find the small Cratex bits are very handy for details and crevices where you need more control, although I've never tried the cut down abrasive balls. Maybe you don't experience the effects I'm concerned about. How small are you able to cut them down?
