A little of last night's work.
Eventually the hull top will be secured to the lower. So for access to the innards, the cargo deck, crew compartment and possibly the engine cover will be removable. This is all .060/1.5mm sheet, the ribbing underneath is simply for strength since most of the middle will be removeable. Some will need trimming as the lower and innards come together.
By the way, my 0.060 sheets (6x24") were remnants from a sign/graphics shop a friend gave to me. He said they usually end up in the trash can, so he saved me a couple weeks worth (around 50 of them). I have bought full sheets of styrene 4x8 feet at a plastic company/dist. in Denver. .080 was about $44 per sheet. So if you don't have a plastics distributor near you check with your local sign/graphics shop. FAR cheaper than the paper sized stuff available at the hobby shop.
I have used these styrene sheets for about seven years. It works with model, epoxy and super glues. I built a dash pod for a famous Honda S2000 here in the states known as the Big Bad Wolf. And a custom gauge pod for a custom truck (and to hide a hole in the top of the dash where the speaker used to be). Both have seen heat and the race car a bunch of abuse are are none the worse for wear.
The triangles and double wall around the cab are filled with epoxy. Probably over kill, but one of the weaker parts of the hull when cab and cargo deck are out.
