I've got a privet sapling that I cut a couple months ago. Two weeks after cutting it, I debarked and roughed out the stave. Afterwards I sealed the back with polyurethane, but I accidentally left it outside in the sun for a while, and the back checked pretty bad. I know checks aren't too big of a deal if they stay within the limb ( these do ) But since this was a sapling it has a pretty high crown, some of the cracks are on the side of the bow. Could these cause the growth rings to come apart when I start bending the wood, or am I over thinking this? I'm open to backing it, if that would help, but if it's a lost cause then I don't want to waste that much time on it. Thanks for your assistance.
