I made this 14 identical piece puzzle from a pallet I found behind Pier One Imports. My guess after microscope review of the grain is Burma Padauk. It has a very crazy grain, possibly reaction wood, definitely pallet quality. One of the boards basically exploded in the planer. The puzzle itself is very easy to make and a great way to break in a new dado set. I used the lowest cost dado set I could find and it shows but only when dis-assembled.

This project is also great to experience how wood warps when sections are removed. Even with all my precautions many of them noticeably warped. I made 18 pieces total and kept the best 14. To be fair one of them got eaten by the radial arm saw; a definite near miss.

The puzzle itself is quite easy to remember how to put together. I made it at first very tight fitting but realized it was too easy to solve, so a little more sanding loosened it up. Now if you pick it up like a ball there is a good chance it will partially crumble in your hands.

Interestingly there is an alternate solution to this puzzle that only uses 12 of the pieces.
US Patent No. 430,502 was granted to William Altekruse in 1890 for this puzzle.

Very nice – interesting too that people were making puzzles like this back in 1890. Did you find the plans on line? My son likes puzzles like this – might make a great gift. Thanks for posting.

As you say, all of the pieces are identical and I would guess that the notches and tab are the same dimension as the square sticks? I would also guess that the cut depths are half way tru. Hummmm. I think I could figure this out. now assembling it is another matter.
