Covering Leonardo Part II

After cutting out and marking up the cover, it is pared at head and tail of the spine to allow it to turn in and lie properly, otherwise the thickness of the leather will be too bulky. On this cover I haven't edge pared the turn-ins as it will look better to fill in the 'well' of the inside covers and that will accommodate the ends of the slips so that they don't show as ugly lumps under the end papers. I have pared the corners so that when they are turned they will also lie flat.
The lines are guides to where the boards will be positioned and will be checked and adjusted before actually adhering to the leather. It is important to ensure that the spine width is exactly right and that the boards are square, otherwise the cover will not be square. 
          I mentioned blind-tooling the flap and it is easiest to do this before attaching the boards. For this I used a double-line fillet wheel which I had made in a small size and is the centre tool of those shown below.

The tool is heated on a finishing stove and rolled along the place where you want a line to appear. Blind-tooling is done without gold, the heat and pressure of the tool make a permanent impression on the leather and darken it. The other tools shown are a single line fillet (above) and a dotted-line fillet below, both also made to order for using on small books. The dotted-line fillet was made from a cog wheel for a clock.
   After tooling the flap the prepared boards are adhered to the cover, edges turned in and corners made. After a light pressing, this will now be ready for the title to be blocked on the front cover. Here is a view of the inside of the cover, before the fore edge sides are turned in.

On the left edge of the left hand board (the front cover) you can see a small square where I have removed an 8mm x 8mm piece, this is to allow for the thickness of the ribbon which will be inserted through a slit in the turn-in and firmly glued down. By removing a little of the board the ribbon will not make a bump in the turn-in. 
In my next post I will show how the title is blocked onto the front cover.
