Make a Secret Hollowed-out Book


I love hollowed out books. They make excellent hiding places or they can be used as unique and tricky double gift wrap. “Ah-ha, it’s a book wrapped up in a book!” I’ve built hollowed-out books before, using the time-honored, frustrating, and very time-consuming hobby-knife method. This time, I decided to speed things up (by hours!) using my Dremel Multi-Max oscillating tool.

Since this made cutting so much quicker, I was also more willing to cut multiple chambers inside the book. Use this method to build a hiding place for your electronics, jewelry, and secret plans for the midnight raid on the cookie jar. It could also be used to make a unique project box for one of your electronics builds.

    I found having a mask was also good for keeping all the book dust out of my nose. Perhaps this is more important for different types of paper.

    I have a friend who had a roommate. The roomate got into some “legal” trouble and the police came to search their house. Part of the search included fanning every single book in my friends 1000+ book collection. This project is very cool but don’t think you will use it to get away with anything. Apparently, people who search houses for a living know all of the tricks! Also, check out potiential roomates.

    Someone on reddit claiming to be a professional concealment designer described a way to make a hollow book that’s a bit harder to identify than this project:
