Sawing and stuff.

With the spine cleaned the book is split into the 3 volumes.
Narrow grooves are sawn in to the spine. The first cut is vertical, being careful not to cut too deep.



Once the depth has been cut (just deeper than the binders cord - 3 ply) I saw at an angle, first one way.....



.... then the other. Creating an inverted V which will lock the binders cord in place.



PVA (or Fevicol for my Indian Chums) is then applied to the spine, ensuring that the adhesive has gone in to the grooves. It is important not to over do the glue.



It is then a question of waiting for the glue to dry.

This is just one method of securing the spine of an adhesive binding, as with everything, practice is the key.
