Checking occurs from relatively fast drying of wood. It can be relatively little moisture leaving the wood after chasing a ring on dry osage, but if it is leaving the wood relatively
fast, then it can check. It is all relative man!

It has happened to me, so now, like others, I seal osage backs anytime I chase a ring.
