    Default Two part question about my new stone

    The stone is a 16k shapton ceramic on glass.

    1a. Do I need to lap the stone before I use it?
    b. If so can I use my 1000 grit wet dry paper on glass to do so?

    Thanks for all your help.

    you can use a ruler to see if the stone is flat.
    as far as what grit, I can't help since I have never used Shaptons.

    I have used the Shapton 16K without lapping when new and not had any problems. I use the DMT 325 for lapping though.

    I check my glass stones by using a reference granite block that is guaranteed dead-flat and some wet/dry sand paper. I take the stone and and draw zig zags from one end to the other, after which, I place it atop of the sad paper and give it a few back and forth strokes. After a few passes, you can lift up the stone and check to see what remains of the pencil marks. Uneven removal of pencil marks show an uneven surface.
