Interesting method, thanks for sharing. I just came across another one I like (though not very scale): Cut fuse formers like you would when making a build-up frame, but only the ones perpendicular to the length axle of the plane. Make them with, say, 4 inch spacing. Then make a stack; 4" foam, former, 4" foam, former, etc. Sand / cut off all foam that sticks outside the formers. Once done, glass the lot. When ready, disolve the foam with aceton (English?). This way you get a nice glass fuse, with formers glued in. No molds, so no reproduction, but I'm not planning to produce a series anyway.

Back to the frame, the idea does not look good now. Making fittings to the frame is difficult, and heavy. All in all, the weight becomes a real issue. And I would like it to fly when done...
