You might want to post to woodworking ng as well Ken.

Dry the slice slowly. Most cracks occur from too rapid dehydration.
I'd put it on the north side of a building and cover it with plastic
for the first 2-3 months. Even that won't guarantee no cracking. You
may even want to put a damp (not wet) cloth over both cut surfaces to
slow dehydration.

Sorry this isn't more specific. But the problem gets much worse the
larger the slice.
