With the narrowness of the frames, you should arrange the pieces so the screws are to the outside of the unit. The drill, with the square drive installed, is too large for the inside of the frame. You should also attach the center support, the piece that runs from front to back and is centered along the width of each frame, through the outside with four #8 x 1V4" wood screws.

From this point the construction of the frames differs. In order for the top and base units to fit the design of the bookcase, the top unit must have a catch rail while the base unit receives a front and back flat rail.

The catch rail of the top unit fits between the frame's side rails, with a V4" extending beyond the side rails, and attaches to the center support with two #8 x 1V4" wood screws.

Make sure that the catch rail is aligned to fit into the top rails of any of the bookcase units - they are all consistently positioned, making them interchangeable.

In the base unit the front and rear flat rails are set flush with the top edge of the frame and attached using the pocket-screw method. Remember that the front rail is only 3" wide, whereas the rear rail is 3³/4". Each of these flat rails also attaches to the center support with #8 x 1V4" wood screws.

The mouldings are next. Mill the material for the crown moulding, the base moulding and the bookcase top to size and thickness. The top edge of the base moulding has a ³/8" chamfer. Cut the edge with a router equipped with a chamfering bit, then fit the pieces to the base. Because there is a solid frame backing the mouldings you can nail the pieces in place with brads. Add a small bead of glue at the mitered corners as you assemble the mouldings for added strength.

The 3" rail in the base unit is toward the front while the wider rail is held to the back. Each rail is not only connected to the frame sides, it is also attached to a center support.

The chamfered base moulding is fit to the base frame on three sides. The secondary wood of the frame is hidden when the bookcase is stacked.
