I think there is a flaw in this cut and glue back together approach. You cut one of the pieces of the puzzle in half and then glue together. Doesnt that make the puzzle structurally weaker?

In the other, better, previous ible you use square dowels and then assemble them together. It gives you a much greater area to glue together, that won;t get torqued like this approach.
