This project is part of the hidden door bookcase.
To me, the book-opener is what puts the magic into a hidden door bookcase. When I ask a client to pick a book to use as the opening mechanism, they will undoubtedly pick a well-known or vintage title, or perhaps a book with a pleasant color scheme. Whatever book you choose, ensuring that it has ample height clearance to fully open hinging outward and that the page thickness is a number that can be divided in quarter inches will save you some headaches later on.
A book with a page thickness of 1 1/2″ is ideal for use as the hidden means of opening the door. This is because you will be cutting out some pages to use solid stock or make a glue blank to fill them back with. This keeps things disguised while creating a sturdy place to mount your hinge and anchor your cable out of sight below.
Prepping the Book
Using a square, make a mark across the pages a little over halfway up.
