I don't think I've posted this before. It is an 18mm center tube inside a phenolic "ring fin". The only connection between the two body tubes are a series of bamboo skewers. The skewers are under slight tension, as is seen in a couple of pictures. I built it by first constructing a pair of centering rings. The front centering ring had radial cutouts to allow the skewers to pass through. The skewers were tacked in place with CA, then epoxied. I think I'm going to rebuild this with a 24mm ceter tube.

Very cool, nice original design. That would be fun to watch on a D12

Do you have an offset lug or something? Pictures 2 and 3 look kind of weird like that

The first was a pair of lugs, stacked, to clear the skewers glued at thenose. They were for a small diameter launch rod. I later glued a larger tube I rolled from paper next to the original lugs. The secong launch lug was much larger in dia.
