You've seen it copied around the internet, but here's the original!

This is another SYAH (Stuff you already have) Instructable. In it, I will be showing you how I created a secret compartment for money or paper that fits inside a working pencil. It can also be used as a handy way to store a grocery list, reminders, or pass secret messages to friends. It may take a couple of tries to get one that comes out right, but it is pretty simple to do. I used a similar idea in a pen, but I was not as pleased with how that turned out. As a result, I have chosen to come back to give this one another try in a more effective, sleek, and clever design.

Step 1: Supplies

Okay, so the supplies list is pretty short for this one. You will need...
- A paperclip
- Something to put into the compartment (Paper, money, note) and of course, a...
- Pencil!
For tools, we will be using...
- Pliers
-Wire cutters
-Drill press (With a vice or some other method of mounting the pencil vertically to the press)
-Drill bits

this was done during World War 2 in the Derwent pencil factory in the lake district in England. <br> The pencils had maps of the areas in Germany where paratroopers were dropped to help them escape. The Nazi's never worked this out and the pencils were not confiscated. <br> There is a small museum at the pencil factory ( they still make great pencils) telling this story.
<p>That is so cool!</p>
Very interesting.
That's a fascinating piece of history... Thanks for sharing!
<p>? :)</p>
<p>I will do it ...</p>
<p>IT WORKS TRYD IT SO COOL!</p>
<p>this is awesome </p>
Nice idea<br>
<p>Awesome idea. Perhaps you could also use a tiny brush to cover the inside with a thin layer of paint, glue, etc. instead of cleaning out the inside?</p>
If you just put a small piece of paper in it the graphite wouldn't be a problem awesome idea too
<p>Thanks for the idea and comment!</p>
Quick tip: Put the pencil in the drill press and make the drill bit itself stationary below. Then the bit will automatically self-center the hole in the pencil.
Thanks for the tip!
Thanks for the tip!
Wow! Cool! Faved
I recently saw a product listed for purchase, and item supposedly employed by the former KGG. It's a variation on your idea but will almost certain require access to a mill or lathe, though some well chosen hand tools and a good vise and drill could make do in a pinch. I think the photo alone gives most of what anyone would need to understand about constructing a similar item, along with some understanding of basic tooling and machining. Beware hardened metals, if using such an item do some research on how to handle machining them before potentially ruining bits and other tools.
My family enjoys geocaching and this would be fun stocking suffers :-)&nbsp;<br> <br> Would you please point me to the web site that sells these bolts?<br> <br> A
Do not fall for those inferior Western Capitalist Pig fakes comrade! Accept only product Mother Russia provides, dah! <br>http://shop.sportsmansguide.com/net/cb/cb.aspx?a=1344362 <br>http://www.spyville.com/spy-bolt-hidden-safe.html <br>http://www.lockpickshop.com/SPY-BOLT.html <br>http://www.amazon.com/Spy-Covert-Hidden-Contents-Container/dp/B0036QVSN8 <br>http://www.amazon.com/Diversion-Valuables-Clever-totally-stealth/dp/B001IZ2VYE/ref=pd_bxgy_hi_img_z <br>http://www.amazon.com/Nut-Bolt-Secret-Diversion-Safe/dp/B007RZ3KXA/ref=pd_sim_hi_11 (Most convincing I see outside Mother Russia) <br> Many more found using simple search. One drawback, almost all are machined so that anyone trained to spot such things will easily see it for what it is. When I do my instructable, my method will make a nearly undetectable connection between screw head and body. I have also considered ways to secure the top so it can be threaded and unthreaded from an actual bolt hole without the top coming off and revealing interior. Two trick to this - One to make it look like naturally occurring damage/distress mark, and second, simple to get small object into it to remove the pin.
Actually, I did see a version of this available from the geocaching website store... here's a link: http://shop.geocaching.com/default/magnetic-bolt-geocache-container.html <br>:D
Thanks for finding that pointer.<br> <br> BTW I was amazed how big a drill bit you used without splintering the pencil body. <ul> <li> Did you choose s soft lead pencil ? <li> Do you think a pilot hole could let you get a clean bore hole ? </ul> <br> Obviously, I enjoyed your ible ;-)<br>
I did not specifically choose a soft lead pencil, and the pencil used is one of those ones you can get a box of 75 for 5$. I got them from staples, and they are plain old number 2 HB. I think a pilot hole is a great idea, and could make things a lot easier. The main way I was able to get such a big hole was by making sure the pencil was perfectly vertical, and I drilled slowly to ensure a clean hole that did not put too much pressure on the body. I did have one that I went to quickly on, and it created a noticeable crack all the way down. One method for creating a perfectly centered hole was brought to my attention by &quot;Matt2 Silver&quot; and he posted a link to an article explaining just that: http://vik-olliver.blogspot.com/2010/02/drilling-down-middle.html <br> <br>I am glad to see you enjoyed it!
I was just thinking what a great gift Instructables is. <br>People like you put a lot of effort into showing what they do, and how they do it, and what they use, and shoot pictures and write descriptions and tool lists and materials lists. <br>And they ask nothing from their students, but a kindly &quot;Thank you.&quot; <br>Well, <br>Thank you.
The Instructable makers would be nowhere without the viewers that enjoy the work they put into it, so Thank you! it is the thoughtful comments like yours that make Instructables such a great environment for thinkers, makers, and doers. I am glad to see you enjoyed, so with great gusto I reply, &quot;You are welcome!&quot;
brilliant!
Glad you enjoyed!
Another way to drill down the center of the pencil would be to use a spare block of wood and drill a hole with a drill bit the width of the pencil. This would give you a hole where you can insert the pencil and be assured it's lined up with your drill press. This also protects your pencil from teeth marks from the vise.
That's a very clever solution, thanks for posting!
an air duster with the long, red skinny straw nozzle would clean out the graphite nicely.
very nice 'ible, btw!
Thank you, and thanks for the suggestion!
You should enter this in the secret compartment comp
I actually can't because of when I posted this... Maybe I'll do an improved version of it, or something. Thanks for bringing the contest up, I never would have known otherwise!
Sometimes I need to take a note and I have just a pencil and no paper. Perfect
Glad to be able to help!

that is very cool, thanks for sharing!
I fully intend to make it one of my first projects when I get my new mill uncrated and ready for use. I'll be sure to &quot;ible&quot; it for the posterity of all. :)
I look forward to seeing it!
Excellent ! <br>But beware the pencil doesn't betray you by automatically, albeit unwillingly, writing or drawing the content of the hidden message when being put inadvertently on a shit of paper while you're not there !&hellip; <br> <br>Great spy stories ended up in the gallows for things as stupid as that&hellip;

This makes me think of something Light would do... (Death Note reference)
Better hope he doesn't read this 'Ible then!
Awesome!!!!!!!!!!!!!!
Glad you enjoyed!
Excellent! Note that if you place something between the vice jaws and the pencil, the pencil will not have &quot;tooth&quot; marks.
Yeah, I have used the trick before... doing it must have slipped my mind, thanks for letting me know!
