Our pal Jimmy DiResta just posted this video of him creating a hiding place for a handgun inside of an old hardbound book. We’ve covered these book safes in the past, usually made by cutting out the hiding compartment with the book still intact. Jimmy disbinds the book, creates a cutting jig, and then cuts the shape out on a bandsaw. He used this to create a gun “safe,” you can obviously cut out any shape you want. Mister Di gets extra style points for using a book entitled Security Analysis.
