Reconditioning stones

    I found a couple of Suehiro stones at a garage sale this weekend. Badly used and abused.
    I usually flatten my stones (take out any dish) with a Shapton glass 320, but these seemed beyond that. They had fairly deep chisel marks as the guy was a wood worker.
    I figured I needed something coarser than the 320 to make any headway in my attempt to resurrect these stones, so I came up with the idea of using my granite plate and some 180 grit paper, wet.
    It actually worked very nicely. Very satisfied with the results, and it was not overly difficult to take out the deep dishes and scratches from these two stones. These are 1200 and 4000 stones.

    Nice job! Next time try doing the "heavy lifting" with a concrete block, and then finish with the wet/dry.

    The gloves: It was just really chalky sanding it down. The paper wasn't too bad Rick. It went pretty quick. But good tip.
    I tried these stones out yesterday. Not too impressed. The Shaptons seem much better.

    I'm at the point where I'm using a disk sander. If I ever find an old school belt sander (6"x48" type) that has a detached motor I'm going to dedicate the machine to stone flattening duty. I hate flattening stones.

    I've got a soft spot for Shapton. They just get the job done and at a very reasonable price.
