Gluing the hull sides to the frames was a bit of a challenge, as the bottom has to curve up at the ends, and the hull sides have to curve inward, so that the ends meet. It would have been nice if this kit had been designed with some sort of building jig, rather than relying on tape to hold things into place while the glue dries.
However, I did find that taping, plus the heavy use of small spring clamps did the trick. Be sure you have plenty of these on hand before you start gluing the hull sides onto the frames. This step is so important that I thought I’d post this image again of the gluing process, showing all the tape and clamps I needed to use.
