Rabbet cutters are the tits for foamcore work: http://www.amazon.com/gp/product/B001JSWKLO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

>Other boxes?

Game boxes or really any boxes can be put in and will be structurally sound to "raise the floor" of a section like you did in your build so you don't have to "dig for pieces". You might have to cut off one wall of the box to make it fit, but that's a great way to get a weight bearing "floor" that's easily reachable if you don't need the empty space in the box for storage. It is a lot faster than building structure elements if you can just cut up a small box you got from packaging at the grocery store, and if lining the box, no one will ever see it.


>Nested trays

I've done that. I have innovation in a bigger box, with one of the actual innovation boxes inside as a holder of play mats.

Use this on almost any cut over 1 inch
T-Square

Use this along the T-Square to make super straight, square lines. The reviews say "make sure and put some excess foam board underneath" but I've gotten by with cardboard and a self healing mat: Linear Foamboard Cutter

If you're making boxes that are to be structurally stable on their own, will be passed about, or will need to support an ailing box, don't skip using this. It makes a perfect glue surface and good looking (but not perfect) corner: Rabbit Cutter. This product packaging shows what a rabbit looks like.

This prevents your table from getting hurt. I believe they all use that chemical (phalates maybe?) to be soft and such, so keep it away from pregnant people and children. A self healing mat

This is more useful on paper itself than long cuts on foam board, as it doesn't stay against the T-Square well. But, for short cross cuts, I think it's superior than Xacto knives and utility knives: [Rotary Cutter](https://www.amazon.com/Fiskars-Comfort-Grip-Rotary-Cutter-45mm/dp/B00DD2W1Q8/ref=sr_1_9?s=office-products&ie=UTF8&qid=1492008006&sr=1-9&keywords=rotary+cutter](https://www.amazon.com/Fiskars-Comfort-Grip-Rotary-Cutter-45mm/dp/B00DD2W1Q8/ref=sr_1_9?s=office-products&ie=UTF8&qid=1492008006&sr=1-9&keywords=rotary+cutter)

I've become a bit of a foamcore junkie, and my designs have gotten much more complex as time has gone on. I keep meaning to post here, but always forget until my design philosophy changes again and I think "I need to wait until I get more pictures of X", then the cycle repeats.

Part of my evolution has been changing how I do joints. I want to start off by saying this -- unless you are a perpetually unsatisfied perfectionist like me, pinning and gluing is more than enough. In fact, I rarely find pinning necessary if you have a good triangle set in several sizes.

For the love of God, don't dove-tail. It is not worth the time you will spend on it and you will hate yourself after a while. I'm not saying this from direct experience, but given the experimenting I have done, just the thought of cutting dovetails makes me break out in hives.

The middle ground that I have found in both increasing attachment surface while maintaining efficiency is making rabbet cuts with the FoamWerks rabbet tool. Rabbets cut part of the foam board away, leaving an extension that consists of one papered side and a small amount of actual foam. You can glue each joint on two surfaces, so it's much stronger, and has the side benefit of hiding foam edges on all but the top surface.

The rabbet is not perfectly calibrated, so there is always 1-2 mm of excess that needs to be trimmed away, and it changes the way pieces fit together by a few mm, but once you get used to that the process of rabbet cutting your joints only takes an extra minute or so per joint. To me, the aesthetics of it make it worth doing.

ALL OF THAT said, if you just want something functional, and are not using it as some kind of twisted art/engineering project, then square cutting and gluing joints is perfectly fine.

I just found on on Amazon Prime for $11.69 for anyone else interested in doing this project!
