I have a 3/4HP buffer and a belt sander. This combination works great when i can smooth steel part with belt sander first, up to 400 grit and then let the buffer take over. I am having a difficulty buffing concave geometries that i can not do on my belt sander. I can use a medium hardness wheel on the buffer and it will "flow" into concave geometry, however even the black emery is not able to remove the grind marks. Can anyone suggest a better wheel/compound combination? I also tried a hard wheel, stitched almost to the edge and that also was unable to remove grind marks from the concave geometry (curved chisel) i am trying to polish.
Thanks ahead
