Meanwhile, I made new bullwarks from brass sheet, and filled any small gaps with superglue, sandings after hardening. I also heightened the aft part of the lower element of the island with plastic sheet. This will make up for a loss of height, because I will replace the kit platform here with a thinner one. I also already attached a couple of PE pieces.
Then, I glued the three pieces together, and filled any gaps with Magic Sculp. The 'chin' under the bridge needed a bit of extra mass so I can square it out properly like the real thing. I also added some Magic Sculp on top of the radar antenna base, because Amagi had a slightly heigher one than Unryu portrayed in the Fujimi kit.
After hardening, I filed, carved and sanded the Magic Sculp to get a square 'chin' and a round radar antenna base. I don't have my punch and die with me on holiday now, otherwise I probably would have used this to heighten the antenna base.
Now, I added the bridge windows. There is a very finely etched PE piece provided for this in the Lionroar set, but unfortunately it is much too wide. I also couldn't find any PE ladders or similar items with the right dimensions to use, so I reverted to stretched sprue. First I placed the vertical members one by one, then bordered them at the top and bottom with horizontal pieces.
The match shows how tiny this bridge and these windows are, which made it a lot of work to line up everything square. But at least the stretched sprue method enabled me to place the correct amount of windows...

I think it is anyway important to invest in this area, as the bridge is like the face of a ship and the windows are like the eyes, to use a figure analogy, so they will always attrackt the attention of the viewer.
Sorry for ther crappy phone-pics, which make it difficult to focus properly...
