This all started with an idea. Totally motivated by this website when I saw that there was a secret department/door contest. I've always wanted to make a secret compartment of my own. But it wouldn't just be satisfactory to have a secret department that somebody can't find I wanted to invent a trick to getting into the secret compartment a special combination that Only I would know, well at least not until I showed you know I made it. If I need to I could always change the combination of the pieces.
This is a chess table that I had made with a secret compartment underneath that is 8" x 9.5" x 3" deep. To unlock the secret compartment you have to move the chest pieces in a very pacific pattern to be able to unlock the door. I have chosen nine moves in all to complete the sequence. The moves are used by chess pieces that coordinate with their moves in the way they play in the game .
To make this all happened I have bought a cheap chess set for about $20 from target. I have a nightstand that I keep a couple books and chose to put The Secret compartment . The unlocking mechanism is is made with two dowels., PVC pipe, string, weights, seven pulleys of various sizes, 16 magnets .
Hot glue gun
All kinds of screws
Stick on cork board
Cabinet door hinges
Step 1: The Plan
First need to learn how to play chess. If you know already then you need to choose an opening or sequences of moves that you want to build your combination to open your secret compartment. This is how I started this project. After I figured out the sequence of moves I started to build a track on some foamboard. Not going to be measurements because that would be a waste of time. Just know it would be smart to measure and then remeasure then remeasure just about everything in this Instructable.
