This is a well known 3 pieces wooden puzzle. This puzzle was published in a article by Jerry Slocum. Unfortunately this puzzle was difficult to make. Because most of the dimensions are related with material thickness and if you don’t have a thickness planer finding the right material was difficult. I decided to make a parametric design according to material thickness.
You can calculate your dimensions easily according to your material. I made mine from pine but I advise using a hard wood between 18 – 25 mm. (3/4 ” – 1″). You can cut holes easily with a scroll saw or a hand jewelry saw. If you want you can make pieces longer or you can change their end shape. You can make rounded ends etc. This puzzle isn’t very difficult to solve but push you to think, for this reason I like this puzzle.
