Flattening waterstones on glass?

I second the sidewalk suggestion, it has worked for me for years.
A friend just gave me a Lee Valley sharpening kit that she had never gotten around to using. For lapping the waterstones, it includes a sheet of tempered glass, a sheet of adhesive-backed PVC laminate, and a vial of 90X silicon carbide grit. The PVC is to stick on the glass as a wearing surface, and for the grit to bed in. Lee Valley sell a 2oz. vial of the grit for $3.95.
Of course, people also use peel-and-stick sandpaper for the purpose. Anything coarser than the stone should work.
Brett, that reminds me of something I read on a woodworking site a while ago. Someone made a wooden cradle for his badly hollowed stone, then turned it upside down on the basement floor with a concrete block on top for weight. He then tied a rope from the cradle to his son's tricycle, and got the neighbourhood kids to take turns riding around dragging the device. Result: a nicely flattened stone without all that tedious rubbing.

yep, i have used the basement cement slab for my water stones.
for my arkansas stones, what I do is this: rub each stone face to face after every sharpening job... this has seemed to slow down the roundess.
my new waterstone, by Global , is so friggin soft... it rounds in no time so I have now taken to a new leveling method: I have a 2 by 2 foot marble sample onto which I tabe wet dry sandpaper... say 220 grit.. and I rub the stone on that about every 3 rounds of sharpening (a round of sharpening at my house is 5 steak knives, 3 all around kitchen knives, a japanese cleaver, 4 folders).
yes, keeping your stones flat will wear them out sooner...
