Thanks, everyone. Consensus seems to be that I need to wait a few more weeks. I've kept the stave clamped to a straight 2x4 next to the return air grille in the house where the air movement is the greatest. When I had it in the garage in the beginning I had a fan on it continuously, but soon moved it into the house when the humidity rose after some rains. When I put my $12 moisture meter on it in the garage, it did read 11% MC. After I moved it into the house for a while, it now reads 6 to 7%. Just did not want to get it too dry. But keeping it in the house for a few more weeks won't hurt it.
