Building A Tic-Tac-Toe Bookshelf

The Challenge
I'd spent some time searching online for the perfect bookshelf, one that was not only sleek, modern, and clean in design, but also had those just-right dimensions. Well, I did finally find such a bookcase (see below) that met the design requirement, but lacked the dimensions and all-wood constitution (it was wood veneer). And since I fancy myself a bit of a craftsman wannabe, I  decided to take upon the challenge of replicating it for much cheaper, using real wood.

Tic-Tac-Toe Bookcase, Challenge Piece
The Materials 
  • (4)  1.5-inch-thick, 60-inch-long, 11.5-inch-wide wood planks/beams
  • (15) 1.5-inch-thick, 15.6-inch-long, 11.5-inch-wide wood planks
  • (6)  3/4-inch-round, 3ft-long (36in) threaded rods (option 1)

    (12) 3/4-inch-round, 1.5ft-long (18in) threaded rods (option 2)
  • Drill and appropriate bits
  • Wood finish
  • Electric sander and sandpaper 
  • Wood glue (carpenter's glue)
  • 12 Metal T-brackets 

The Dimensions
60W x 11.5D x 84H inches

The Schematic
Before any construction took place, I created the schematic (see below) so that we would have something to follow. It's always good to have a diagram of some sort.

The Construction

Initial Goal
The goal was to build the bookshelf by having 6 threaded rods travel  from top to bottom inside the vertical supports to ensure stability.

Augmented Plan
Because of our wood selection, using 2-by-8s rather then plywood, we soon realized that we had to deviate quite a bit from our initial construction goal in order to support the bookcase. Rather than use the 6 long rods, we had to use 12 shorter rods, wooden pegs, wood glue, and t-brackets both to support and reinforce construction. 

Our Steps 
  1. We went to local hardware store and had the wood pieces cut to size, according to the dimensions specified above in the Materials section. 
  2. We center-drilled a 3/4-in round hole, 12-in deep in the top of three of 15.6-inch-long vertical planks.
  3. We threaded a 1.5ft-long rod into each of the first three vertical planks. 
  4. We followed that by drilling three 3/4-in round holes (about 13in. apart) in each of the 4 horizontal planks.
  5. We assembled the first shelf by threading the rod in each of the first three vertical planks into the appropriate hole in the first horizontal plank and reinforced with wood glue. Once assembled; this left three exposed, vertical threaded rods that would be used to attach the second row of vertical planks (see photos below). 
  6. We took six more vertical planks and center-drilled a 3/4-in round hole, 12-in deep in both the top and bottom. Then threaded a 1.5ft-long rod only into the top, as we'd done in step 3. 
  7. We threaded the bottom of three of those six vertical planks into the exposed rods from the first row we assembled and reinforced with wood glue. 
  8. We threaded the second horizontal plank in place, matching the three holes in it with the three exposed rods from the second set of vertical planks. 
  9. We could and would now attach the third row of vertical planks and follow that with the attachment of the third horizontal plank. Keep in mind that we are still reinforcing with wood glue.
  10. We would assemble the forth row of verticals and forth horizontal plank in a similar manner, leaving all the final three vertical planks to attach.
  11. For the final three verticals, we center-drilled the hole in the bottom of each and threaded each into the final three exposed, vertical rods, reinforcing with wood glue.
  12. We attached t-brackets to each joint (12 total) in the back of the bookshelf for even more reinforcement. 
  13. We seals any joint gaps with wood finish and applied sanding where needed.
  14. Staining and varnishing are the remaining tasks. Note: We've not gotten around to this task, so the bookcase remains in its natural state for now.

The Results
So, without further ado, here's the semi-finished product:

  1. This is so great! I've been trying to figure out how to build one of these forever! Your measurements are actually almost exactly the same as I need and the pictures are a HUGE help. Looks great!

  2. Wow, thanks for stopping by, and I hope your project turns out nicely. You might also want to use a wood that is thick, but also pliable. The boards we used were imperfect, but for me, that's what gives the shelf character. Good luck!
