I don't see a thread about build-over jigs that can be used to form thin foam into a model aircraft design, be it real, or imagined. What I do is upcycle trash foam, often starting with foam drink cups and foam that has been used in a box to protect a product. The packing foam can come in very odd shapes, but it can be upcycled into a build-over plug with basic carving skills. Foam drinking cups, especially the large ones, can be upcycled into a thin foam shell fuselage, or wing and since they are easy to find, or rescue from the trash, make for some excellent thin foam skin panels. I am not sure there is an interest in making thin shell fuselages, or wings on the cheap, so I thought it wise to see if a new thread generates any inquires first. I have been posting most of my work in RC Groups over the years, but am a big Flight Test fan, so am thinking some folks might want to see some examples of what is possible using this construction method. There are a lot of projects that could be updated already posted in this forum, but they have boxy bodies, or fuselage that would be easy to round out.
