mine's just a little bitty thing, 1x4 but I'm having trouble with lapping it. I've got SIC from 80 stepped up to 12 micron. both times I've lapped it I've dished the center as the sic breaks down to dust and packs into the center area that doesn't get pushed outside the ark's surface area, with long axis ellipticals primarily.
how much SIC do you lay down, and how do you spread it out? I'm taking a smallish pinch and trying to essentially "salt" the surface as best I can, but it clumps.
and if there's any other threads with pictures or better descriptions, I'd love to see them, I couldn't find them.
