Dan Johnston like a lot of us get asked this question, so he put this together. "I thought your blog group/friends would like to see how tough wood boards can be. I had one returned with the nose snapped off, a 6" rip of the wood and glass on top/bottom and one side. The kid just said 'it broke'. All I know is he really did it hard against something that wasn't going to move. No water inside so his story doesn't match reality. It's fixed and looks perfect but maybe some day he'll tell us what really happened."
You take care.
