This instructable shows you how to make a game board for chess, draughts (checkers in American) and backgammon from duct tape.
Step 1: Bin bag foundation
As a foundation for the board cut a black bin liner up so that you have a square of plastic at least 12 times the width of your duct tape (60cm in my case).
Duct tape the plastic to your work bench so that it is lightly tensioned.
Then stretch alternate colour strips of duct tape across the plastic as shown in the photo.
Make sure that the edges of the tape are as close as possible without overlapping.
Step 2: Slice'n'dice
Next mark the edge of the outer two bits of tape at regular intervals the same distance apart as the tape is wide (about 5cm in my case).
Then using a ruler and a sharp craft knife slice the strips across the so that you have separate strips of alternate colour tape.
You should end up with 8 strips.
Step 3: Shuffle the deck
Rotate every other strip through 180 degrees and replace it where it came from so that you have alternate colour squares.
Step 4: As if by magic
Duct tape the stips to the workbench again so that they line up with the edges as close together without overlapping again.
Necessary usage of another material other than duct tape... Magic tape the internal edges and across the strips for strength.
Add some strips of a third colour of tape to either end so that the board is rectangular - about ten percent longer than it is wide. 45cm by 55cm is tournament backgammon size so if you're picky then this is your target size.
Step 5: Flip reverse it
Carefully remove the board from the workbench leaving all of the tape in place and turn it over.
Tape it back to the workbench this with the underside face up.
Step 6: The invisible step
If you're a real duct tape ninja then you might be able to skip this step. Since this was my first duct tape build I used clear sticky back plastic to fix the parts constructed so far into place. Difficult to see in the photo but it's there if you look closely.
