Whilst an artist in residence at Instructables, I took up playing chess at lunch times against Dave. With chess on the brain, when I went home at night I noticed that the black and white tiled kitchen of the family I was staying with would be PERFECT for a game of giant chess.

Looking online to see what was already available, I found three problems:
1) Size: none of the sets advertised as giant, were actually very big
2) Ease of storage: all of the sets I found online were injection moulded plastic. I'd need a lot of space to store them!
3) Price: for a truly giant chess set I'd need to shell out $300+.

My solution was a simple laser cuttable giant chess set made from a light and strong plastic material called Coroplast, it's the stuff used for political and housing signs. The pieces would be comprised of two parts each that when slotted together would stand up and give a good representation of a chess piece, while being quick to disassemble and easy to store.

Anyone with access to a laser cutter with a bed size of 24" x 36" can use the included files to make their own copy of this giant chess set.

Step 1: Design & Prototyping

All of the pieces were designed in the free trial of my preferred CAD software, Alibre Design.

I first laser cut each piece from cardboard with a 6 inch base. Upon taking them back home to test them out I found I'd guessed the tile size in the kitchen wrong and so quickly scaled them up to a 9" base, giving me a king with a height of 27".

The 12 Alibre files are included in this step should you wish to modify them.

Wonderful guide! Thanks so much for sharing this.

One question: Is it possible to open this file in another CAD program other than Alibre? We don't have that program. Or could you save the original file in a format compatible with Vectorworks?
Jayefuu (author) in reply to gubbins4everMay 20, 2013. 1:16 AM
Step 2 has vector files (DXF) that you can open in Inkscape (free) and most 2d CAD programs.

Anybody know of cheap places to acquire coroplast? Would love to recycle rather than purchase new. Seems pretty ubiquitous with all the politicians, etc.

Ya might try out yardstore.com they have some really random stuff for sale.

Ask around during local elections, they might be willing to give you their old signs.

This is amazing! I'm sharing this info with the guys who run the chess clubs at the three schools, well done!
Dusk Shadows says: Oct 20, 2012. 10:15 PM
We have these at our school only HUGE!! like 3x the size of these and no1 ever uses them so it was kinda a waste of money

Thanks for this - we don't have CAD or a laser cutter, but adapted the designs and made a similar chess set. Works well (except when windy - thinking on solutions to that!) - thank you.

This is so totally cool. Somehow I missed it. Thanks for all your hard work making this and sharing it here! Hope your day shines!

Thanks, it was a lot of fun to make.

cool!

Nice! Great job. And I like Rimar's story, too!
kinetike says: Mar 30, 2012. 11:12 AM
I am so going to use this idea in my classroom, however, I will make the students redesign the pieces to be sea life as I teach design at a marine science based school! How fun! I can teach them the use of CAD to create their pattern and then teach them the use of some hand tools. Thanks for posting this!

Amazing! If I promise not to boobytrap the TP will you let me play a blitz game?

totally cool.

@Jayefuu; Hi! Tweeted and sent to my chess-fanatic relative. Cheers! Site

When you're down to a few pieces, how do you remember where the board starts and finishes?
Jayefuu (author) in reply to KitemanMar 25, 2012. 12:05 PM
Lay tape around the outside of the board. Or argue about it :p
Kiteman in reply to JayefuuMar 25, 2012. 12:10 PM
Nah, drink beer and then argue about it!
Jayefuu (author) in reply to KitemanMar 25, 2012. 3:10 PM
Awww you made me miss British beer. It's all fizzy and cold here. :(
canucksgirl in reply to JayefuuMar 26, 2012. 3:14 PM
... so you guys drink flat and warm beer? o_0 ?

BTW, Canadian beer is better than the yanks. ;)
Kiteman in reply to canucksgirlMar 27, 2012. 7:41 AM
Not entirely flat, just not pressurised and frozen.
Jayefuu (author) in reply to canucksgirlMar 26, 2012. 3:32 PM
Yup!
canucksgirl in reply to JayefuuMar 26, 2012. 3:41 PM
Ok, I'm sorry, but.... eeeeeeeeeeeeuuuuuuuuuuuuwwwwwwww... :-\
Jayefuu (author) in reply to canucksgirlMar 26, 2012. 3:44 PM
Ha ha. We say warm, it's just warmer than US beer. Cellar temperature rather than fridge temperature.
agis68 in reply to JayefuuMar 26, 2012. 10:47 PM
beer is drinked ONLY when is well frozen in 4C and in well frozen glasses...anything else is peeing....at list that we say in Greece...hehe. Once i tested this british beer and immediatly I had a puke.
Kiteman in reply to agis68Mar 27, 2012. 7:40 AM
Too much flavour for you? Or just too strong?

;-)
agis68 in reply to KitemanMar 29, 2012. 5:11 AM
i didn't liked the flavor of dark warm beer...no offence!
Jayefuu (author) in reply to agis68Mar 27, 2012. 7:10 AM
"beer is drinked ONLY when is well frozen in 4C" - that's because it has no flavour :p
canucksgirl in reply to JayefuuMar 27, 2012. 1:47 PM
Not only that, but 4C, is "4 degrees above zero".... In Celsius, zero is the freezing point. "- 4C" would make more sense. ;)
canucksgirl in reply to JayefuuMar 26, 2012. 3:48 PM
Oh, ok. That's different. ;)

You know we have a brand here that comes with a fancy chill label. When its cold enough (for those hot summer days), it changes color to let you know its chillin'. ;)
Jayefuu (author) in reply to canucksgirlMar 26, 2012. 3:55 PM
Those damn marketers.
canucksgirl in reply to JayefuuMar 26, 2012. 4:06 PM
I know. Its a bit of a farce actually.
Kiteman in reply to JayefuuMar 26, 2012. 4:53 AM
Oh, I have a nice bottle of St Peter's Ruby Red waiting for me at home...
Jayefuu (author) in reply to KitemanMar 26, 2012. 10:33 AM
I hate you. :)

I have a week or so to wait before my next 23l batch of home brew IPA is ready to drink.
I have a London Porter kit that I will start making tomorrow.
CarolAnn525 in reply to yellowcattMar 30, 2012. 4:56 AM
Oh you guys are making me miss the pubs of England!

I could go for a pint or several pints of scrumpy.
agis68 says: Mar 26, 2012. 10:39 PM
nice work...I guess you already had the black/white tiles at your space and then you said..."so i have it why not take advanceof it playing my favorite game" anyway is cool
rimar2000 says: Mar 26, 2012. 5:29 PM
Nice work, James!

In the little town where I was born, of 12k people, was a pharmacist –Don Cecilio Errasquin– who became very famous during the 20th century by the witty banter that made ​​many people fall.

One of them was: chatting with one of his friends, doctor, told him that his favorite sport was chess, to which the doctor said that chess was not a sport but a game. They discussed a while and then it ended.

Weeks later, the pharmacist called the doctor to play a game of chess at home. To the surprise of the guest, instead of taking him to the room took him to the backyard, where he had built a giant chessboard and the pieces were made of hard and heavy wood. The game ended by physical exhaustion!

The above parts are now in a museum in Buenos Aires.
