i found this puzzle in a book, and made one from some scrap pine i had in the shop. it’s a nice little project to use up leftover pieces, as it doesn’t require much wood, and can easily be scaled to any size. it is constructed in the same fashion as this game by garyk. the six pieces go together to form a 3×3x3 cube. it sounds easy, but the puzzle lives up to it’s name. i’ve had about a dozen people try it out so far, and only 2 have gotten it (30 and 45 minutes). if anyone builds one and needs help, let me know and i’ll send you the solution.

Very cool—I think I will definitely be building one (if not more) of these … but I have to ask a very simple question … you build and finish the cubes first and then glue long-grain to long-grain, correct? I’m not sure why but at the moment I’m having a moment very similar to the one the ape men had when they found the obelisk in Kubrick’s 2001: A Space Odyssey

Given that you can bet I’ll need the solution!

Great puzzle. I may build some. One question. How did you edge the cubes? Once you cut them down to individual cubes they are going to have at least 2-4 edges that you couldn’t edge before you cut them. Did you do it on a router table? If so, what did you use to hold the cubes as you ran them across the table?

Nice project to drive me closer to the edge. I understand I’m very near it now.

i’m glad you guys like this so much. i guess i should have posted some of the production methods along with the pictures. i started with a 3/4” thick board about a couple feet long. i then cut it on the table saw into 3/4” x 3/4” x 2’ strips. just a little tip: put the board on edge against your saw blade, then set the fence up against the other side of the board. this will set your cut to the exact same thickness as the board’s thickness. i then cut the strips into 3/4” cubes on the miter saw. again, i placed the board against the blade. i then clamped down a stop block against the other side of the board. you’ll need a minimum of 27 cubes. however, i recommend making a few extra in case you ruin a few with the router or in glue up. to add the chamfer on the edges, i used a router table. since the cubes were small, i didn’t want problems with the gap between the bit and fence. to take care of that, i clamped scrap pieces of 1/4” plywood over the router table top and fence, and then with the router running, raised the bit up into the plywood so that just a small portion of the bit was exposed to cut the chamfer. after the cubes were all cut (and finished if you choose to do so), i just superglued them into the neccesary shapes. given shapes of the pieces, you can’t always have an end-grain to to end-grain glue up. it’s not really neccesary though, after they set up, i tested them and couldn’t break them apart by hand.

Did you cut these as individual blocks, then glue them up?

yeah, i cut the blocks individually then glued them together. i cut up a bunch of blocks and made 14 puzzles all at once.

Have your say...
