November 30, 2006 4:43 pm. Iâve made bookcases in different widths with no supports between the gables. The widest one Iâve made has 86â³ wide shelves and exhibits zero sag. I make my stuff entirely out of MDF and never use screws or nails. As you probably know, MDF has no grain and canât support its own weight.
1 Decide how tall you want the finished shelf unit to be and how wide. 2  Bookshelves are traditionally 12 or 16 deep; of course, you can customize to suit your needs. 3  Decide if your bookshelf will have an open or a closed back. 4  If you keep the back open, your books may lean on or touch the wall behind the bookshelf. Apply wood glue to the support blocks for the bottom shelf and set the shelf in position. 2  Drill and countersink pilot holes in the side of the bookshelf and attach the shelf with 2 wood screws. 3  If you decided to use support blocks for the center shelf as well, install it now as you did the bottom shelf.
