Step 2: Cut down the metal

Sorry I don't have a lot of photos for this intractable. What you want to do here is cut down the front cover of your book so that there is space for the rachet to fit comfortably above it.

Optionally, if you want to make a more secure book, you may want to have a second ratchet on the bottom side of your book, if so, obviously you will have to cut down your front cover even more
