Introduction: How to Make 3 Simple Hardware Store Puzzles
I've made my fair share of puzzles over the years, but most take expensive tools and costly materials to make. For this project, I pushed myself to find and build puzzles that could be made from inexpensive off the shelf parts and that don't need any fancy tools to make or solve. If you have a love for puzzles and a lack of tools, these simple-to-make puzzles are for you.
Step 1: Ringleader
This is a simple puzzle to build but is the most difficult of the three to solve. It features four rings bound by paracord. Can you build and solve it without needing to cut and replace any of the paracord?
Step 2: Tools and Materials
Step 3: Prepare Paracord
Cut the paracord into four 9 in. lengths and remove the inner core of the paracord. The core can be discarded as it's not needed for the puzzle.
Step 4: Melt Ends
Melt one end of the paracord and pinch to a point with your fingers. It's best to wet your fingers before doing this as melted nylon can stick to your fingers and burn. Melt and pinch a little at a time.
On the other end, open the paracord a little bit and melt just the edges of the cord. This end needs to be open but melted to prevent fraying.
Step 5: Create Loop
Feed the first end through the metal ring and into the opening of the second end. Similar to how a snake would eat it's own tail.
The inner melted end needs to pass though the inside of the paracord once and should meet the opening again while inside the paracord. You should be able to feel it under the cord at the visible end. Once at this location, verify that the loop is small enough that a ring will not pass through it. If a ring passes through it, you need to make your loop smaller.
Step 6: Fuse Paracord
Fuse the exposed end to the body of the paracord by melting it with a lighter. This will prevent the paracord from coming apart in the future.
Repeat these steps with three more rings.
Step 7: Solution
The solution to this puzzle is not easy. It's actually so difficult that I cannot accurately describe how to do it. The video linked here is how I discovered how to assemble and disassemble the puzzle. The steps on how to reassemble the puzzle (where you will be starting from) start at timestamp 3:21.
Step 8: Nut and Bolt
The Nut and Bolt puzzle has a simple objective of assembling the nut and bolt together. With the nut on the wrong side of the bolt, solving this will surely make you scratch your head.
Step 9: Tools and Materials
Step 10: Drill Hole Through Bolt
Clamp the bolt in a vise and drill a 1/4 in. hole through the center. This should be done slowly and as straight as possible. A drill press or lathe can also be used. Using cutting fluid will aid in drilling and will reduce the stress on your drill bit.
Step 11: Paracord
Cut the paracord to roughly 24 in. in length and remove the core of the paracord. Melt the ends of the paracord in the same manner as done in step 4 above.
Step 12: String Puzzle Together
String the nut and bolt on the paracord and then place both ends through the washer. String the paracord through the ring as shown above.
Step 13: Fuse Paracord
Feed the closed end into the open end of the paracord about 1 - 2 in. Fuse the exposed end to the body of the paracord by melting it with a lighter. This will prevent the paracord from coming apart in the future.
Step 14: Solution
To solve this puzzle:
- Grasp under the loop as shown on the ring
- Slide that loop through the washer
- Move the closest object through the loop (nut in this picture)
- Pull the loop back through the washer
- Grasping the loop with your left hand and the nut and bolt with your right hand, rotate the entire paracord counter-clockwise until the loop has move back through the washer
- Once the loop is on the other side of the washer, pass the nut through the loop and pull the paracord tight by the ring
- Twist the nut onto the bolt
To solve in reverse, follow the exact same steps, no reverse order needed.
Step 15: Ring and Spring
This deceptively simple Ring and Spring puzzle shouldn't make you scratch you head for too long. It can be assembled from off the shelf parts. The following steps were only taken to make the spring more presentable and pleasant to hold.
Step 16: Tools and Materials
- Spring (3/4 x 7 in.)
- Metal Ring (1/8 x 1 ID in.)
- Sand Paper
- Disc Sander
- Buffing Wheel
Step 17: Flatten End
The end of the spring as it came originally was sharp and not enjoyable to handle. I fixed this by grinding it flat on my homemade Disc Sander.
Step 18: Sand and Finish
I used increasingly fine sandpaper to remove the dull look of the spring.
Once sanded up to 600 grit, I turned to my buffing wheel to really make it shine.
Step 19: Solution
The solution to this puzzle is quite easy. From the assembled version of the puzzle, rotate the ring clockwise by 90 degrees. The ring will now easily lift off the spring and slide off the end. To put the puzzle back together, simply slide the ring back on and rotate the ring counter-clockwise back into the original position.
