This is a pretty straightforward jig for binding books. It consists of a plywood leftover with a metal bar that is compressed by two bolts. Finally there are two stoppers to align the pages.
Regarding the binding itself, I drilled holes in the paper, then I used nylon string to bind the pages together. Wood glue is applied to the back of the book and to give the final touch, a piece of duct tape is placed over the glue.
