A co-worker dropped off a small (key chain version) of this puzzle on my desk. I looked at it and thought with only 7 pieces, this should be a breeze. However, I soon found the puzzle very challenging due to the number of potential wrong solutions and the required order of operation during assembly. Anyway, his version was pretty fragile due to the size, so I thought I would scale it up. My version (3" cubed) was made from a scrap 2x4 and a 3/16" diameter dowel.

Here is video showing how it works.

Step 1: Tools/Materials

Tools:

  • Table, Hand or Band Saw
  • Drill Press
  • Drill Bits
  • Sander
  • Ruler
  • Pencil

Materials:

  • 2x4 by 2' Long
  • Wood Dowel 3/16" Diameter x 18" Long
  • Glue
<p>I really like these type puzzles even though I am not good at solving them without look at the solution. I need to build some now. Good project. </p>
<p>Thanks. I like puzzles as well. As for solving, I have to resist the urge to look up the answers on the internet :) </p>
<p>Your pictures are great. Looks easy to follow.</p>
<p>Thanks. Yeah, the pictures make it look so simple...it's not.</p>
<p>I think I will try it anyway.</p>
