kleebtronics CNC Coffee Table

Chessboard Coffee Table

During my Designing For Digital Fabrication class at ITP, I decided to construct a coffee table using a CNC machine and use the top of it as a game board for Chess and Go.

Fabrication

The table was designed with a storage compartment in mind. I used a variation on dovetail joints to hold the sides together, and cut out small half-circles in the top piece so that the game board could easily be lifted out.

The game board was etched on the CNC router. I used a jig to make sure both the chess board and go board were centered on each side.

Instead of acrylic, I decided to use liquid plastic to ensure that the surface was entirely smooth.

Unfortunately, my pouring skills were not exceptional, and I had to sand down the spillover plastic afterward.

After a few coats of finish, the table looked great!

Chess Pieces

Each chess piece was modeled after a specific percussive sound wave. I used Processing to capture a snapshot of each sound wave and saved them as PDF files. From here, I could import the files into Illustrator, trim it down to the size I wanted, then use VectorWorks to extrude the line three-dimensionally.

The only pieces I modified were the knight (bent forward to reflect asymmetrical knight shape) and the king (added a cross to the top). All of the pieces were printed on a Z Corp 3D printer, one set in white and one in black.

For the carrying case, I roughly measured the contour of each piece and created a template for the laser-cutter. The case is made up of two sheets of acrylic held together with standoffs.
