You will need:
- A bookcase. I built my own, but virtually any sort of furniture will work: bookcases, china cabinets, dressers, whatever. Just be sure there is a clear amount of space underneath, and the surface for the hatch is at least half an inch thick.
- Magnetic Child Lock
- Concealed Hinges
WOW! Thank you so much to everyone who has commented and checked out my instructable! I had no idea people would find it this interesting! Keep experimenting and sending me your thoughts and variations on my design!
Also, Cousin Eddie wanted to see if neodymium magnets could open the lock, instead of the key, here are his findings:
"Anyway I checked to see if I could open a latch with simple neodymium magnets & found that it took at least 3 small (watch battery size) neod. magnets to open it. BUT you have to have the polarities of all the magnets (including the one inside the latch) lighted up.... otherwise it wont work. Simple to do though. Think I will mount the magnets in my own "key". "
Thanks for the findings!
I received a request for some pictures of what my bookcase looked like as a whole. I put it them in at the end.
Step 1: Cut Out the Hatch...
Step 2: Install the Hinges...
Check the movement of the hinges, and adjust them if need be. Ideally, the hatch should still be flush with the shelf.
Install a small block opposite the hinges, to keep the hatch from falling into the compartment below.
Step 3: The Fun Part...
Step 4: Build a Box Below and Complete...
Here is a photo review of the entire method of opening the compartment:
