Springback Binding

How to make a springback
2017-12-13
I just finished my first springback binding. I wanted to try it out to see if I liked the structure after attending Don Etherington's demonstration in October. As it is a trade binding, it is much rougher than a fine binding. There are a lot of elements that do not require the precision that is needed in a fine binding.
I made this springback for my boarding school friend who is getting married in a few days! The springback opens flat and can stay open for a long time without compromising on the structure, so it's perfect for a wedding guestbook. I have made a few other fine bound wedding guest books and they opened relatively flat. The photo above shows the spring and how the textblock is pushed up out of the spring to allow it to open flat.
I chose to make the colours because as I recall my friend's favourite colour is green and they are having their wedding in Hawaii. The photo above shows the joints, you have one joint on each side of the textblock, which is made of two sheets of marbled/decorative paper with a strip of book cloth in between. These are sewn onto the textblock as the first and the last signature.
The photo above shows the spring, textblock with the hinge and the split boards. The spring is made taller than the boards so that it can be trimmed and shaped to the height of the boards after both the spring and the boards are attached. The piece of cloth glued to the spring is first stuck to the hinge (the blue leather flap, that is on the textblock), then the hinge is glued up and inserted into the split boards.
In the photo above you can see how the spring is attached to the hinge. The cloth from the spring is glued to the hinge, but it is not glued along the spine of the textblock, this is what causes the springing action of a springback.
The photo above shows the springback before it was covered. I glued up the hinge (only the center part where the cloth is adhered, as you have to allow space for the turn-ins) and also glued the split of the boards and inserted the hinge into the split. The spring is then cut to be slightly taller than the boards and then hammered to get a tight headcap.

I think the springback is an interesting and fun structure to make and it's not as time consuming as a fine binding. That being said I'm not sure when I will make my second springback. Maybe I can challenge myself by making a miniature springback...
