When removing the bark off a freash cut or cured stave, it is a good idea to seal it with shellac, elmers glue, Tite bond, whatever. Also it's a good idea to remove the sapwood and chase the first growth ring before sealing.
BTW, I've had cured staves check when I got them out here to a drier climate, now I wrap them in plastic for a while to slow the dring a bit.
