I had a brainfart this morning that transformed a $10 spare scrap of plywood into a really cool 5' tall, designery bookcase that some yuppie idiot would probably pay a few hundred for.

Warning: this procedure involves extensive lame woodworking techniques such as glueing and stapling with nailguns. If you're a dovetail joint purist, you probably don't want to read any further.

Step 1: Ingredients

Tools you will need:
- a table saw
- a nail gun

Material you will need:
- at least a quarter of a plywood sheet, 96" long x 12" wide x 3/4" thick.
- at least 60 1.25" brads for the nail gun
- wood glue
- sand paper
- pabst blue ribbon, to help you channel your inner bubba.

Note: User earay indicates that MDF might be a better substitute for plywood, as it is cheaper and easier to paint when complete.

Step 2: Cut Boards

In this step, we're going to create our 16 6" x 12" boards.

How you create these boards isn't important. Keeping to the exact specified dimensions isn't necessary either. What is important is that all the boards be identical to fairly tight tolerances. One way to get there is the following procedure for cutting these boards out of a quarter of a 4' x 8' plywood sheet.

First, cut a 12" x 96" plank out of your plywood board. Set the rip fence of your table saw at 12" and pass the board through the saw once. You will only use that plank for this project -- use the remaining 3/4 of that board for something else (or else, build 3 more of these bookcases). (Actually, feel free to adjust this width to your taste).

Next, adjust the rip fence of your table saw to a little bit less than 6". Rotate the plank you just created 90 degrees, and subdivide it into sixteen identical 6" x 12" boards. Remember to pass the last board through the table saw, just to ensure that it's exactly the same size as the others.

Also: always use a push stick when moving wood through the table saw! I don't want to hear no complaints from any of you fingerless whiners. "I used to program computers for a living." "I was an artist" Wah wah wah. Use a push stick.

Step 3: Assembly: Layer 1

Pick three boards, and attach them together to form the first layer of the bookcase, as shown in the diagram below.

To attach the boards, first lay down a line of glue. Then, holding the boards in place, fire brads up through the bottom of the bottom board into the edge of the joining board. These brads will staple the joint in place while the glue dries. About 3-5 brads per board should be sufficient.

Note that the vertical boards are stacked on top of the base board -- not alongside it.

Grevious bodily harm warning: it's easy to "miss" when firing the brads up through the bottom board into the edge of the vertical board. Make sure that your fingers aren't anywhere near the place where a brad might unexpected appear. Protect your fingers! You only get ten of them, and then they're all gone forever.

Step 4: Assembly: Layer 2

Now, place two lines of wood glue atop the vertical boards from step 1, and glue another horizontal board on top to make a box. Fire some brads in from the top to pin the board in place while the glue dries.

Once the board is in place, glue two new vertical boards atop the horizontal one. In the previous step, the two vertical boards were placed along the left edge and the back-right edge. This time, place the boards along the right edge and the back-left edge. This should give you clearance to place the nailgun beneath the newly glue boards, and to fire brads up through the horizontal board into the vertical boards, pinning those boards in place.

Step 5: Assembly: Layers 3, 4, and 5.

Repeat the previous step for the next three layers, alternating the placement of the vertical boards for each layer. In this manner, an "S" shaped pattern should emerge.

Step 6: Assembly: Put a Lid on It.

Finally, take your last remaining board, glue it to the top of your structuer, and pin it in place with brads.

Step 7: Finishing

Wait for the glue to dry.

Sand the rough edges off the plywood.

Finish the bookcase to taste (stain, seal, paint, etc.).

Some variations:
- turn the bookcase on it's side, and now it's a bookshelf suitable for mounting on your wall!
- build a bunch of these units and stack them together. It's modular!
