DIY Hacks & How To’s: Make a Multi-Book Secret Compartment

DIY Hacks & How To’s: Make a Multi-Book Secret Compartment

You are probably already familiar with the classic “Secret Book Compartment” project. There are variations of this project all over the internet. There have even been a few version that been featured in MAKE as well as on the MAKE YouTube channel. The basic concept of a secret book compartment is simple. You hollow out a large book and you use the cutout space to hide stuff. Unfortunately, most versions of this project have one major problem. You can only hide objects that are smaller than your book. However it is possible to hide larger objects by combining multiple books into one large multi-book container.

Hollow spy bolts

Hollow spy bolts

Brian Dereu of Hollow Spy Coins showed us how to make this hollow dead-drop bolt for stashing secret messages back in MAKE 16. It’s not hard to do if you have access to the necessary equipment–a drill press, hacksaw, vise, grinder, and the appropriate taps and dies. But if you don’t have those tools, or you don’t have the time to use them, and you still want a spy bolt, Brian will gladly sell you one hand-made by his family and him for the not-unreasonable price of $37.

In the Makers Market:  Dead drop spike

In the Makers Market: Dead drop spike

For those of you who aren’t up on your tradecraft, a “dead drop” is a place where spies or other clandestine-y folks drop off items for later retrieval by other agents. A “dead drop spike” is a particularly ingenious little container devised for the purpose. Basically, it’s a hollow metal spike, with a threaded watertight closure at the top. You put your top-secret microfilm or whatever inside the spike, take it to your dead drop, and stomp it into the ground with your foot. Then you cover it up with a rock or a piece of trash or whatever. The lid has a pull-loop built into it, so that when your contact comes by later to clear the drop, he or she can grab the spike by the loop and yank it up out of the ground again.

When I first learned about dead drop spikes years ago, I had a bit of a nerdgasm and decided I had to have one. I scoured the tubes, but alas, no one was selling them. Imagine my delight when, a couple years later, I discovered that Brian Dereu of Hollow Spy Coins had added a custom-machined dead drop spike to his inventory. I ordered one immediately, and could not be more pleased with its quality. That was at least a year ago, and as far as I can tell, if you’re in the market for a dead drop spike, Hollow Spy Coins is still the only place you can get one online.
