Going back to the ships now...
Hull damages:
Here begins a fascinating part of this project (the very part which determined its choice, I must confess): this is entirely based on the so called “Damage Reports” the US Navy produced throughout the War for every damaged ship.
A large number of them are available on Web and they show real "autopsies" of every ship.
Thanks to Tracy White at:

Minneapolis suffered two main damages this night:
1- Her entire bow, forward of capstans was demolished and bent downward to an angle of 70°.
Damage description:

After cutting-off the bow:

In dry-dock, showing the damaged section:


And « Minnie » underway for Mare Island with temporary steel plates bow:

2- A torpedo hit in the no2 boiler room vicinity :
The damages:

A spectacular opening to the Sea:


The opening is right under the armour belt (of which one full plate is missing). It will show easily through the diorama transparent resin.
Now the build:
Scribing the damaged areas:

« THE » frightening moment… was cutting out the bow:

Both halves are shortened up to the next undamaged bulkhead.
Those sections are then scanned to get the correct shape and dimensions to design a PE bulkhead section.


And there goes another custom PE!
First I designed the PE simply by directly CAD drawing on the original plans:
Same for boiler room area: (I’m using USN official plans of Tuscaloosa as a guide)


Building (!) the damaged areas (PE, plasticard and cyano glue bonded paper -thanks to Jim Baumann for this later trick)
First comes the #2 boiler room structure:



Digging the hole into the hull:


Dry fit:

Et voilà !
