Introduction: Twin Nut Puzzle

About: My hobby is make tutorials on electric projects.

In this tutorial I make nut and rope puzzle. Making this tiny project is enjoyable and simple.

For your friends and family, the solution could be difficult because it is not obvious. A Steps of the answer is in the stage 5 to 8 .

Supplies

We need following tools to make this puzzle.

  • Saw
  • Drill or Drill Press
  • Drill Bits
  • Sander
  • Ruler
  • Pencil
  • Lighter

We need following material to make this puzzle.

  • Wood: (8cm x 3cm x 1.5 cm)
  • Rope: 1/4" Diameter x 24" Long
  • 2 x Nuts ( M12 )

Step 1: Drill Holes

First, take a 1.5-cm-thick wood block and cut it into a 8x3-cm rectangle with a saw. Mark a centre using a pencil, and then mark two locations from the ends. Drill a 15-mm hole in the centre and two 6-mm holes in the other two locations, as shown in the photos. Use a sander for the proper finishing of this wood block. You can use cardboard if you don't have wood blocks.

Step 2: Feed Rope Through Wood

After you've finished the wood block, cut a 24-inch-long rope that's 1/4-inch thick. Cut this rope using scissors and seal the frayed ends of the rope with a lighter. This made it quite simple for the rope to pass through the little hole.

Then, as shown in the picture, take this rope and thread it through the center hole. Then make a square rope knot like the one in the picture by passing two ends through this middle rope gap.

Step 3: Pass Nuts

Then take one M12 nut and pass one rope end through the nut hole. Then pass this rope end through the left-side 6 mm hole of the wood block. Tie knots at the ends of the rope, and do the same for the second nut and rope end.

Step 4: Challenge !

You can see both nuts are on separate ropes. The aim is to combine two nuts without disassembling this puzzle. Give your friends or family the challenge of combining both nuts and enjoying them. Please follow the next steps if you don't have an answer.

Step 5: Tip 1

If you don't have an answer, follow all of the pictures step by step. First of all, make the middle rope loose and choose any one nut to pass through this as per the picture.

Step 6: Tip 2

Then flip the wood block over and pull the rope until the rope knot is on the opposite side, as shown in the last picture. 

Step 7: Tip 3

Then loosen this middle rope knot and pass the selected nut through this rope space. Pull the rope from the opposite side of the wood block. 

Step 8: Tip 4

Then, in reverse order of tip 1, pass out the chosen nut. Both nuts have now been integrated in one location. Reverse the procedures to separate the two nuts.

Great project! Question for the metrically challenged- Are the hole sizes important or can I use say 1/4” for the sides and 1/2” for the center hole? (I don’t have many metric bits). Also - does the center hole need to be large enough for the nuts to pass through? Thanks so much for the help 🙏

You can use cardboard instead of wood. Size can be change as per your situation. But centre hole must be smaller then nut . Because if hole is large then nut easily pass directly.

This is absolutely perfect for our St. Nicholas' Day / Santa's workshop, where our homeschool kids make gifts for their families on Dec. 6. Might be too late for this year, but I think we'll definitely make this next year! Thanks!
