>When you refer to insulation I assume you mean the box itself.
>What is your box made of? Is it just black painted wood?

This image shows the box cooker here >>963313 in progress. The layers of insulation in this one from inside to outside is: 1 inch of cardboard, 2 sheets of Celotex blackboard, 2 sheets of Styrofoam, outer cardboard box. Everything is bolted together and the bolt heads were covered with cardboard to help prevent thermal bridging. The door uses the same insulation with additional 1/4" plywood and a later-installed handle. A wooden frame was added when it was apparent it needed wheeled transport. It was painted black inside to help raise ambient air temps for baking.

>The tilt and allowing the oven to sit flat seems like a conundrum.

The bottom has a removable black-painted metal tray. Peg holes in the back wall allow the unit to be tipped and the metal tray to be leveled on them.

If I were to do this again, I would drop money on some aerogel blanket insulation for the sides and airloy for the bottom. That would allow for a very compact design, much lighter, and still have great temperatures.

>The petals are more or less similar in design regardless of the solar oven style?

Pretty much.

>Are the panels flat?

Yes. It is based on this design:

>Could I, say, elongate it into a rectangle?

Of course.

>Is there a certain angle they should be in relation to the oven?

Yes, see link above. When fitted together, they angle properly.
