The playing board
Aluminum STOP Sign 2'x2' ( DON'T go out and steal it!!! )
Step 2: Chess Board
The sign I had wasn't in terrible shape with a few dents, no kinks and little corrosion from the years it was bolted to the post
I began by taking the dents out, sandwich the sign between 2 - 2x4's on a vise and strike it firmly repeat as needed... File off any of those stubborn high domes...
Aluminum is a soft light metal that sands fairly fast and easily, Sand the chips scratches and corrosion off the sign... I used a dual action random orbital sander beginning with 80 grit sand paper and successively finer paper. I used 2 sheets each of 80, 180, 220, 320, 400, 600, 800, 1500
Once the board has been sanded sufficiently you will notice that it has a smooth even finish nearly polished, I buffed with an electric buffer and a wool pad and a mild compound...
Clean the board thoroughly to remove any compound
I then covered the entire board with a single sheet of vinyl ( sign shops will have this type of vinyl)
On the vinyl I laid out an 8 square by 8 square grid with 2" squares, making the playing surface 16"x16". Using a razor blade cut out the grid pattern and remove half the squares. I embelished the sides with some engine blocks and wrenches and then cut them out and removed the pattern...
There are several ways to etch the board, you could sand blast the surface in a blasting cabinet or you could acid etch the surface. I chose to acid etch the surface using knowledge that can be found on several instructables and all over the web and I'll leave that to you to explore and take the best course for you.. Be careful and use all the safety precautions.
Once etched I removed the remaining vinyl and re-polished the entire surface with a wool pad and a mild compound then a foam pad with a fine compound followed by a high quality automotive/marine grade wax.
