Introduction: Wood Dowel Puzzle
There are eight dowel segments that you must fit into a box. You should be able to get seven pieces in with ease. What about the last piece?
This very simple project was built from scrap wood (minimal cost) and it took about an hour. I tested the puzzle on my two teenage children and both gave up after 5 minutes so I would say it’s slightly challenging.
I understand the originator of this logic puzzle was Tesa Timonen of Sweden in 2002. I reversed engineered this version from online pictures.
Step 1: Tools/Materials
- Saw (table, miter, band or hand)
- Wood Clamps
- Wood - 5.5” x 3” x .5” thick
- Wood - 1.5” x 19” x .5” thick
- Dowel – 1” diameter x 20” Long
Step 2: Drawing
You will be building to the drawing. Yep, I just gave away the solution.
Step 3: Base
Cut wood for the base as shown.
Step 4: Sides
Cut 2 long and 2 short sides as shown.
Step 5: Box
Use glue to attach the sides to the base. Apply pressure with wood clamps. Remove excess glue and sand as necessary.
Step 6: Dowel Segments
Set your table, miter or band saw to a 30 degree angle. Cut 1” dowels to the lengths shown.
Step 7: Finished Build
Stain or paint as desired.
Step 8: Walnut Stain
Step 9: Try to Solve - First Attempt
Step 10: Try to Solve - Second Attempt
Step 11: 5 Minutes Later...
Well, actually my kids gave up and went to play on their phones. So, I'm taking this to work on Monday.
Step 12: Solution in Pictures
If you plan to build this for someone, you might want to print solution instructions to go with the puzzle.
Hope you enjoyed the project!
