WoW !!!!!!!!!!!!!!

Does anyone have other ideas for waterproofing the castle? do you think verathane would work?

This is fantastic!!!! Well done.

I guess if you don't want to use the rivets??? Packing tape works just as good...
Then if you want to water proof it, you can paint it with fiberglass resin <- waterproofs almost anything!!!

I  have never heard of box rivits and think this is a win/win post!  Yes, a few sales may be made, but you've also given us something in return with the free plans. - Not to mention all the other fun things that come to mind that I could do with something like this (I'm thinking - giant cardboard maze!) 
No offense taken here!  I'm heading on over to buy  :-)

is that real or not?

THIS IS AWESOME!!!

dude, this is total spam. if you wanted to advertise your little rivets, you could at least try to do it discretly, like, make a username like "superawesomeguy" or something. you should be fired from your own company

I will not click on any of your spammalicious links. Sorry!

just to keep things commercial free can the collective list a source of fasteners from other than mr mcgroovys website???

interesting how he puts as little information as possible on the instructable so that you have to click on his links to get the rest of the information along with ordering instruction for his products.

my instructable following this "new" standard would be how to move earth, rocks and other materials using this ingenious gadget http://www.flickr.com/photos/8874816@N08/3405389433/sizes/l/

wow mine too

this is cool

I was going to say this isn't just advertising then I saw the username, spamtastic!

nice! i appreciate this, as finally I can have a good house, despite my living in an alleyway in san francisco!

I need to build a cardboard castle for a grocery store display for the floral dept. Dose anyone have an idea for a smaller one or maybe just a front? Crimsonpride2002@yahoo.com Any suggestions are welcome. Thanks.

Nicely done.

Oh wow, my son and daughter would have a blast with this. It would have to go outside however,so it wouldent last lond after it rained a couple of times. Is there a way to waterproof cardboard???

i built one like this when i was 10 i put it outside water proofed it and every thing , then the spiders came.....

I don't think this is spam but it does read like a giant advertisement. But the product seems pretty cool and I'll keep it in mind if I decide to make something out of cardboard. Otherwise, this is a really cool instructable and the castle reminds me of this big cardboard castle we had in my third grade class. :) Also... Psh. Duct tape looks cooler. :P Not to mention you can make so many other things with duct tape.

I think this is spam also. I did not see anything on how to actually build the castle, just the words telling you to go buy the connectors and follow the directions on another site.

I agree, this is spam. I love the product, but this kinda violates the spirit of the thing.

This isn't an instructable, this is a "buy this thing and you can follow the instructions online instead of the book (plus we get free advertising)"

This seems like spam....

it is to big for my school desk.

Tape the edges of the card board with duck tape to seal them, then spray the cardboard with an automotive primer let it dry and then paint with a outdoor latex paint like you would use on your house, it should last quite a while
