Construction of this puzzle was...interesting. Tom's idea was to glue the pieces together out of flat stock, but where's the fun in that? I decided to mill them from solid stock, a decision I later questioned. The protrusions are several thousandths undersize relative to the grooves to insure smooth, non-binding movement. Those of you who make things will immediately understand that doing so creates a lot of headaches and a lot more work. In the end it was worth it...this puzzle moves smoothly all the way around with no binding. The frame is oversize by 25 thousandths to give the pieces room to expand and contract with humidity.
