First, an overall photo of progress so far.
Construction step 7 includes adding ladders to the air intake assembly, so I did that first, using PE parts.
The aft deck parts come next, including life rafts, 1.1 guns, and gun director tubs. The directors in the tubs are PE, and very tiny. Actually, I regret not using the kit parts, which were more visible.
I replaced the kit depth charge racks with PE. The charges themselves have to be made out of 1mm long .030 plastic rod.
I also installed the PE deck rails at this point. The fore rails:
And the aft rails:
Also during the phase, the pillars for the catapults and some little block-like pieces go on amidship. I also put on the little pieces that were called for in construction step two, hoping I wouldn't knock them off during the rest of the build. I did knock the jack staff off the bow, so I'm not going to replace it till later.
