I'm sorry I didn't save the Fulcrum progress photos.
But you may see in this 1/48 F-16i Sufa project, I used the very exact same technique. Still a scaled-up Bruno's addictive template by the way
.
Assembled with the same 1 mm thick brown cardboard, sanded carefully to get better shape and proportion, then coated with clear resin to get extra rigidity. Sanded lightly between layers.
(Sometimes I use melamine lacquer instead of clear resin).
Finished with spray paint
