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.
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
10) Tape
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)
