I finished the parts on the Arizona tonight, which leaves photoetch and detail painting, and wanted to summarize things so far.
3-D printed parts
The biggest addition to the model was the mid-build decision to switch out the kit fighting tops and gun shields for 3D parts. I had been very impressed with the 3-D printed Pearl Harbor mooring quays (shown painted at left), and was able to located 3D printed fighting tops , gun shields, and shields for the quarterdeck 1.1 inch mounts.
The tops and shields came in orange plastic (an odd choice) and the difference between them and the kit parts is striking. The new tops are in front - the kit parts are on the ship and behind. The photo also shows the size of the kits gun shields, which are short, thick, and without vertical bracing.
The last photo shows the boat deck sanded smooth of the old gun shields,
and with the tops and shields painted and ready for installation.
Again, I was able to finish with the kit parts tonight. The next steps is installation of the kit's photoetch, which consists mostly of railings, but also has some gangway and crane detail. Then it's detail paint and install flags.
I am hoping to finish off the ship's Pearl Harbor appearance by adding the white awnings and extending the boat booms. The ship's boats really ought to be removed, so I'll probably do that as well.
