I just returned my Norton lapping plate in favor of sandpaper and a granite tile. The problem I have now is that my 1k stone is super smooth. It feels about halfways between my 4 and 8k stone for surface roughness.
Previously I was using a 120 grit paper to lap the hone, but just tried an 80 grit. Still very smooth, not really a noticable change in surface texture with the grit change. I've been using Norton 3x paper.
Anyone have any suggestions on how to rough up my 1k a little? What do others use for lapping their 1ks?
