Lapping a benchstone?

[Jason B.]

Not hardly what?

The stones grit cannot get finer. It's the grit found on top of the concrete which becomes ground finer. After leveling a stones surface can 'feel' finer. Should this occur merely work it a little more on the coarse concrete until it returns to it's original feel. Otherwise, it takes sharpening many knives to return the stone to it's original feel.

Smooth like a sidewalk, not like a garage floor.

Figure 8 will produce a more evenly ground surface, circular may induce a angled pitch on the stone.

Never heard of sand being used, I just use water.

This process is really simple, if it takes you more than 5 minutes your doing it wrong.

This was what I was replying to. DM

Are you saying it takes you MORE than 5 minutes to flatten your stones? Velvet or corduroy don't make good stone flatteners...
I 'scrub' 'em just the way I'd scrub a dirty frying pan.
I've never spent more than 3-5 minutes flattening any stone. Of course, I don't use a micrometer to check edge-to-edge measurements. I just put a couple of pencil marks criss-crossing the the stone, and when they are gone, hold the stone up to an aluminum straight edge with a bright light behind. If there is no light, the stones are flat.

Still don't understand.

So it takes you longer?

If the comment was toward the way of scrubbing a stone I would recommend re-reading my post.
