Secret Pencil

Introduction: Secret Pencil

This is the easiest secret compartment project I know of. Depending on the depth of the hole, you can store a $20 bill, short message or anything that will fit.

Supplies

1 pencil
3/16 drill bit
Drill or dremel tool

Step 1: Remove Metal Eraser Cap

Carefully pull off the metal eraser cap. Grab it firmly and wiggle it a little as you pull. It takes a little effort but it will pull off.

Step 2: Drilling the Concealment Hole

Use a 3/16 inch bit and drill a hole in the center. Any larger size drill bit and the wall thickness will be too thin. Drill an inch or more depending on your needs. A lathe works best for drilling but a hand drill or dremel tool will work fine. Even a finger powered hand drill will work.

Step 3: Fitting the Eraser Cap

Align the small crimps in the metal to the original position of the cap. Push on till the cap is back in place. Pull on and off a few times to create tiny tracks in the wood. The cap should remain snug for several 100 removals. Eventually the tiny tracks will wear out and the cap won't stay on very well. That's when you make a new one. Another 10 minutes!

Step 4: A Finished Secret Pencil

This project took less than 10 minutes. Have fun!
Secret Pencil tip. Make one from a shorter old pencil with a broken tip. Keep it with several new pencils that are freshly sharpened. No one will want to "borrow" an old broken pencil.

    Thanks mangoes, I actually was making these in high school for myself and friends. The original concept is probably 5,000 years old.

    Don't think that didn't cross my mind. Several years ago I made one that I kept on the dash of my car. After a few days I decided to keep a handful of other pencils and a few pens with the secret one. And here is a great secret pencil tip. Make one from a short and used pencil with a broken tip and place it with a few freshly sharpened new ones. If someone wants to borrow one, they will choose one that can write.

    Thanks Unbeatabob. Please see the Secret C-Clamp which is sort of a spinoff of the Secret Pencil

    Wouldn’t a bill get stuck and not be able to come out ?

    I would just use a pair of tweezers and out it comes! Since this is basically a disposable secret compartment, if you have to break it to get your $$ or message, no problem. Make a new one in a few minutes!
    Several years ago I had one on the dashboard of my car for at least 2 years. No one ever gave it a second glance. Then I needed some emergency $$ and there it was! I have a new one there right now.

    Not only that but there were similar secret compartments in Victorian era writing Instruments. Now go way, way back in time to ancient Rome and even they had a version (a contemporary writing instrument and probably for poison). Go back even further in time and the Chinese had their own version (once again, probably for poison). I prefer a more peaceful use and will send my sweetie a love note!

    this was done in WW2 by the Derwent pencil company ( UK). They hid maps inside the pencils that were given to troops who were to parachute into Europe. The maps showed the area they were being sent to and were for use if they escaped the enemy. The germans did not work out that this was happening during the war and did not take the pencils away from the prisoners.
