I came across IBM's website on burr puzzles [http://www.research.ibm.com/BurrPuzzles/] and decided to make one.

"Burr puzzles are interlocking puzzles known in Europe and Asia since at least the 18th century."

I first picked "David Winkler's favorite level 5 burr". This is a "notchable" burr meaning you can construct it entirely by notching the pieces. I used a bit of red-oak I had laying around. This burr is 6 units long, 2 wide. The unit size in my case is 3/8" which I found a good size. The design in this case is a "5.4" meaning there are 5 moves required to remove the first piece, then 4 to remove the 2nd.
