I would love to know why my comment was down voted. I'm making a fair point that nobody else has yet made, and thus I would argue that it adds value to the conversation. Sure, my comment was short but I believe it was as long as it needed to be to make the point. To clarify though, in case I was wrong on that assumption, I'm stating that simply because one can't spot any breaks doesn't mean there aren't any. Maybe Eng did a really good job of splitting the wood along the grain and piecing the wood back together once he slipped each piece inside the bottle. And then he could have finished the wood in such a manner as to hide any cracks still visible.
