Mark,

Last month I put the advice of the Porch to the test [1]. =A0I found
that it definitely helped to have a liquid to float away the debris,
that cloth-backed aluminum oxide flattened my medium India stone without
the deep gouges I got from the sidewalk (perhaps not all concrete is
created equally?), but a coarse diamond stone left the freshest cutting
surface. =A0My largest diamond "stone" was not big enough to properly
lap my India stone. =A0

A large DMT lapping plate appears to be a good investment, given its
utility and durability. =A0Once you get your stones lapped, I would
recommend regular maintenance (perhaps annually, depending on how much
you sharpen) to keep a fresh, flat surface with minimal effort. =A0Once
you rehab a deeply dished oilstone, you might not want to do it again.
