USS Nautilus - Final Edition

[DrSchmidt]

Mark the deck openings, roughly cut them with the diamond wheel and the file it to end dimensions:







I decided to make the limber holes on the lower side closer tot he original (in contrast to the 12 mm hole depicted in the manual). For marking I made a styrene stencil. Drill the holes out with a 1 mm drill and file them to their final shape using a diamond file.









Mark the position oft he bow plane shaft. Here precision is mandatory as precisely positioned shafts make the assembly oft he mount absolutely easy. If everything fits, it’s just a snap together job. Note that the mount was adjusted to the inner contour oft he hull near the seam:

We start with the bow section. Limber holes, deck openings and the holes fort he bow planes have to be defined. The bow planes will be fixed which proved sufficient on the prototype. The bow planes are tilted upwards 30° with respect tot he horizontal. That was not the original state, but during the test runs oft he Nautilus vibrations occurred at the bow planes that disappeared when the planes were tilted 30° upwards. So this was adopted. I work forward along my self-made manual:







Clean the seam with 400-grade sandpaper and flatten the base plane:



Same with the PU resin bow plane mount:



The mount is further hollowed out to reduce its volume above the waterline:

After successful test runs with the prototype, I've decided to incorporate my experiences with it in a second, improve version of the Nautilus. This time it will reach its design waterline and will have a higher battery capacity. I start with a complete set of parts that would also make a kit (in case I do it):
