I haven't really done much hand-finishign in the past, so this was just a guess. I have Norax polishing belts X65, X45 and X30, but nothing finer, so I stop at about 320 grit. I know that one has to drop one level down on sand paper so I figured start with 220, then 320, 600 and either stop there or go to 1200. I do most of the grinding with 60 grit belt and some of those scratches are deep, and hard to remove.
How do you guys avoid overpolighing the edge of the heel? A friend suggest I hand-sand with tip facing me.
Thanks for your response. This is a new territory for me.
