    Default Lapping Naniwas

    I was just wondering if Naniwas need a special lapping plate for lapping or if I can just use the sandpaper method. I know Nortons are weird about that type of stuff, that's why I figured I'd ask before I do anything to my Naniwa 1k.
    Thanks

    320 wet/dry sand paper on a flat surface works fine,.
    If you have the funds and desire you can use 325 DMT plate

    I'd go for the DMT 325 plate for two reasons.

    The first is that you can use it as a hone for really badly chipped edges and the second is that sandpaper can leave little pieces of grit embedded in the hone.

    So if you do use sandpaper, make sure you dont have grit in the stone before you put a razor to it.

    Good luck!

    I have not had any problems with wet/dry sand paper, but I think that using DMT is more cost efficient and better overall solution than sandpaper

    I would agree on the DMT. In my opinion, it really is the best all around solution for the price and can be used on virtually every other type stone out there as well.

    I have the exact same issue (lapping a Naniwa 1000 stone), but I already own the smaller Naniwa 220 grit lapping stone. Is that stone ok to use for lapping the larger Naniwa? Also, just out of curiousity, the 1000 stone already looks to be as flat as a sheet of glass. So why do we do this lapping step first? Just wondering. Thanks!

    Draw a pencil grid on it and give it a few swipes with the plate and see how the grid is removed and you'll have a better idea of how flat it is by how much of the grid is gone.
    Be careful how you treat people on your way up, you may meet them again on your way back down.

    Based on the advice from Don I bought the DMT 325, and I find it super easy and efficient to lap with it. I wish I had used it for my Nortons. Besides you have the opinion of the master and I can only tell you that by brief talking with him and Don, my skills have improved 1000%

    I also use a DMTC for all my lapping needs. It will leave light scratches in hard hones that can be lapped out quickly with a barber hone or something similar, but for Nortons, Naniwas, Coti's, and BBW's that I have, the DMTC is great for lapping.
