7. Building the case

  • The bookcloth should be at least 1 1/2" more than the length of the boards and at least 1 1/2" more than the measure of the book taken from foredge to foredge around the spine (2 widths plus the thickness of the textblock). Glue up the entire sheet of buckram with the glue machine.
  • Place the first board on the glued-up bookcloth on the left side of the glued cloth with at least a 3/4" turnover left at the top and left side of the board. Any extra book cloth can extend from the bottom edge.
  • Place inlay on book-cloth. To determine the position of the inlay, lay the textblock onto the already placed board such that the textblock aligns with the board as it would when fully cased in. The foredge should be placed about 1/16" of an inch away from the board’s foredge thus allowing for a foredge square. This will leave the textblock’s spine extending beyond the board’s spine edge the width of the hinge. Place the inlay onto the bookcloth such that it is about a board’s thickness away from the spine and aligns lengthwise with the textblock’s edge. Remove textblock and check to ensure that the inlay is both paralell to the board and aligned with it at the top and bottom edges.
  • Place second board on book-cloth. Lay the second board on the book-cloth with a space between the board and the inlay equal to the space on the opposite side of the inlay.
  • Trim the excess bookcloth from the boards leaving at least 3/4" for turnovers
  • Trim the corners at a 45 degree angle leaving at least 1/8" off the corner of the board. It is better to initially cut too little rather than too much. If the corner is trimmed too close to the board there will not be sufficient material to cover the board
  • Turn the top and bottom turnovers onto the board as follows. Starting in the center, turn the bookcloth onto the inlay and begin by working in the hinge areas between the inlay and boards. Next, working from the center out, turn the bookcloth onto the boards and work it down tight over the board’s edge and onto the board
  • Pinch the bookcloth at the foredge corners and turn the foredge turnovers onto the board. The turnovers are best worked onto the boards from the center out toward the ends
  • With the case finish-side up use a bone folder to work the edges tight along the sides of the inlay and the boards at the hinge areas
