7. Attach the remaining three interior shelves at the top, bottom and 48-1/4 inch marking to complete the tower base (figure A).8. Flip the unit over and attach the backing with staples.
9. The two front trim pieces will have a rabbet cut for a nice, tight fit. Attach the two front trim pieces and two back trim pieces of the tower with glue and 1-3/8 inch brad nails. The pieces should be flush with the top shelf, leaving a 3-1/4 inch under-hang at the bottom for the legs (figure B).
10. The linen tower will have adjustable shelving, so grab a shelf-pin jig thats set to drill 1/4-inch holes. Drill two columns of holes on both interior sides of the tower at the top compartment of the unit.
11. Nail the trim pieces along the exposed edges and on to the sides, continuing the trim on the middle shelves (figure C).
12. Attach drawer slides on to each of the 12" sides of the 21 9/16 x 12" piece of birch plywood, flush with the edges.
13. Attach a drawer pull to the 22-3/8 by 1-3/4 inch clear pine tray trim. Attach the trim piece to the 21-9/16 inch side of the tray (on the side where the drawer pulls are closest to the edge) using glue and 1/2-inch brad nails (figure D).
14. Miter the edges of the 10 by 3-3/4 inch back pine and one 3-inch side of each of the 12 by 3-inch side drawer pieces.
15. Attach drawer glides to one of each of the drawer sides. Make sure the wheels face the mitered edge of each side, and the glide is flush with the non-mitered side.
16. Secure the mitered edges of the sides and back together with glue and 1/2-inch brad nails. Staple the bottom of the drawer on to all three sides.
