Thanks Martin and Rob!
But don't give me too much credit; I'm just doing what everyone is doing here.
Meanwhile, I finally got a bit of workbench-time.
First, I tackled this 'wingy' platform at the rear corner of the flight deck:


The PE item included in the Lionroar set for Unryu does look like what is visible on photo's of Katsuragi, and on plans of Unryu, but unfortunately doesn't resemble the structure visible in the photo's of Amagi:

My first plan was to cobble it together with different bits of PE, starting with some parts of the above piece. But I couldn't get this to work… Guess I have to buy me some more PE!
Next plan was to scratch build it with 0,1mm nickel silver wire. It started out ok, but I quickly found that on something this fine, even the slightest build-up of CA glue on the joints shows too much. Gluing with CA lacked adjustability too. I abandoned it at this stage:

Then I resorted to stretched sprue, glued with Tamiya extra thin (green cap). This took some time and care, but worked very well!
The trick is to start simple, and keep one piece too long so I could use it as a handle:

I worked on top of piece of paper. This soaked up excess glue, so the stretched sprue wouldn't stick to the work surface too much. It stuck a bit to the paper anyway, but not so much that it was easy to pry loose with a scalpel.
Next, I started adding piece by piece, letting assemblies dry in between:






I have been told that a match doesn't really show how small these kind of details really are. So now I'll try with my index finger:


And before someone comments on my finger: it is actually very fine and elegant, thank you very much!

And the piece in it's place. Well, more or less, as I left it loose with the 'handle' still in place for painting.


Cheers,
Marijn
