Homemade cryptex from PVC pipes.
The cryptex works much like a bicycle's combination lock, and if one arranges the disks to spell out the correct password, the tumblers inside align, and the entire cylinder slides apart. In the inner compartment of the cryptex, secret information can be hidden.
Step 1: Materials
1) 1(1/4)" coupling (x1)
2) 1(1/2)" coupling (x4)
3) 2" coupling (x4)
4) 2" threaded ends caps (x2)
5) 1(1/4)" PVC pipe (x1)
6) 1(1/2)" PVC pipe (x1)
7) PVC glue
8) Bolts and nuts (x4)
9) Sand paper and dremel tool
The number of 1(1/2)" and 2" couplings, bolts and nuts, depends on how many dials you are making. (I used 4, because I made 4 dials)
Step 2: Tape
Take both 1(1/2)" couplings and tape them, so they fit into the 2" threaded ends caps, because they naturally do not fit inside each other. (I used the ugly Christmas tape, because you won't see it anyway)
When they fit nicely, glue 1(1/2)" couplings inside the 2" threaded ends caps.
Step 3: Glue
Glue the 1(1/2)" pipe inside one of the previously made threaded end cap (2" threaded end cap with 1(1/2)" coupling inside)
Step 4: Sand
Take other previously made threaded end cap and sand its inside, so the 1(1/4)" coupling can fit inside it.
When everything fits, glue 1(1/4)" coupling inside the previously made threaded end cap (2" threaded end cap with 1(1/2)" coupling inside)
Step 5: Glue
Take the 1(1/4)" pipe and glue it inside the threaded end cap made in step 4.
Step 6: Adjust
Make two pipes the same length, I made mine 5.7 inches and I made 4 dials. You can adjust your length depending on how many dials you are making.
Step 7: Sand
Sand the 1(1/4)" pipe, so it fits inside the 1(1/2)" pipe.
Step 8: Gap
Take the 1(1/2)" pipe and cut a 0.5 inch gap in it.
Do not cut it completely, so the pipe doesn't collapse.
Step 9: Base of Dials
Take the other two 1(1/2)" couplings and cut them in half, to make four.
Sand down their inside just a little bit, so they turn smoothly on the 1(1/2)" pipe.
Then also cut a 0.5 inch gap in each 1(1/2)" coupling.
Step 10: Stopers
Drill holes in between bases of the dials.
Then place and glue bolts and nuts in the holes.
Step 11: Dials
Take four 1(1/2)" couplings tape them, then fit and glue them inside four 2" couplings
Step 12: Almost Ready
Place your dials on the pipes and your cryptex is almost ready.
I also had to adjust a length of the dials a little bit so they fit nicely into the pipes.
Step 13: Stoper
Cut a little piece of 1(1/2)" coupling or pipe and glue it at the end of your dials.
This is needed so the dials don't fall when you open your cryptex.
Step 14: Finished
Your cryptex is finished!
Now just decorate it to make it look like an actual cryptex.
Place your keyword letters on the place above the gap on the dials, so they (key letters) will be opening the cryptex.
You can hide there anything you want to keep out of reach of your friends/parents/siblings, like document or money.
Hope you enjoyed:)
