Nomex is tricky stuff to use. It plays all sorts of tricks when you try and do curves with it.How they get it into a Tornado shape I don't know! Maybe heat will make it stretch a bit?
Also its easy to overdo the resin and start filling up the honeycomb which kinda defeats the point in using it.

you can get over expanded (ox) nomex that will bend nicely in one direction and not too bad in the other. with a 10 mm core, it should not be too bad to get it into a small beach cat hull.
when you are applying nomex to a part that is not to be cooked (non pre preg) you take a flat work surface and secure some plastic film to it, coat the film in a thin layer of epoxy, pat the bonding side of the core into the resin then stick the core onto the part. you need a thin layer of bonding putty on the part. apply vacuum and voila.
