How to Make a Cryptex




About: We are a group of Engineers, Tinkerers, Designers, Programers, and Nerds ! ---- and Since April 2011 We also have a Cupcake Maker

We know there are a couple of videos showing you how to make a cryptex, but we decided to make one since the other ones were made out of metal and the one made from PVC opened from the outside. The real Cryptex' actually opened from the inside, a bit harder to make but well worth it. Hope Yall like it

    Well, let's make sure he's using something fragile enough to be dissolved from vinegar. Otherwise, it's just a stink bomb.

    I like the design very much. I didn't follow your plans exactly because I had a lot of PVC scraps lying around.

    I like the idea and will try it but you are naming parts in the video that are not on the list and keep changing the sizes as you talk about them. I am having a lot of trouble sorting it all out.

    Here is the basic concept.

    You fit in, a 1 1/4 pipe inside of a 1 1/2 pipe inside of a 2" pipe.

    TO do this, you need to sand down the 1 1/4 pipe to fit the 1 1/2 pipe.

    there is a lot of Sanding since the PVC doesnt fit into each other the right way.

    This video used different sizes than in the materials list. so I went to your site and all the things there were video's. and more importantly the same video here, thus no extra help

    I agree with RedSoldier, your material list and voice overs dont match up, could you please re-release the correct material list, it would b nice :)

    Was a little hard to follow at times, but still awesome.

    Very nice instructable!  If PVC didn't cost so much in my country, I would build one of these.
