Step 15: Constructing the rear section
* Rear side (C), 14 5/8" x 4½"
* Rear back (D), 39½" x 4½"
* Rear bottom (E), 38" x 5"
On the two side pieces (C), drill two holes 1½" from the bottom and ¾" from the end. Make the holes large enough for the 3/8" hangar bolts.
Drill two more holes higher up on the sides, large enough to accommodate the alignment pegs you'll be using. I used ½" dowels for strength.
Assemble the back section as shown in the diagram. Biscuit joints are best, but screws, dowels, or cleats are acceptable too. If you use screws, plug the screw holes for best appearance.
Be sure to attach one sliding rail to each of the rear rails before screwing the rear rails into place.
