Step 1: Materials
Two metal plates cut to the same size.
A Bi-Directional Ratchet
A place to weld
Pages to put inside your book
(potentially you may also need a wrench and a needle or awl)
Step 2: Cut down the metal
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
