Been working on the Yorktown for more than a month before I made enough progress for some pictures.
Most of the time was spent working on the fiddly little catwalk railings--measuring and cutting; painting; repainting; fitting them in and trimming; placement and gluing; having them fall off; replacement and regluing; having them fall off; re-replacement and re-regluing; and finally, they stuck in place. A few spots will need a touch-up with a brush.
The rails are a mixture of WEM's Enterprise/Hornet set and Artwox.
Yorktown carried quite a battery of .50 cal water-cooled MG's, which WEM kindly reproduced in PE. Unfortunately, they don't fit the catwalks very well, where many were installed on CV-5. I think the problem is that Tamiya underscaled the kits (info on the web indicates the kits are closer to 1/719 or 1/720 than true 1/700). In most places, I had to turn the .50's sideways to get them to fit. In one spot, port and aft, they actually had to overhang the flight deck to get them to point outward. I might not have bothered with them if I'd known ahead of time--but I guess they look OK.
Aft starboard--a battery of four .50's
Foreward starboard--another battery of four.
Aft port--a battery of three; a single .50 was located further aft on the catwalk, between the 5" mounts and the guntub (for another .50) at the corner of the flight deck.
Progess on the island. The .50's located there (there were five of them in place) fit better.
Assembled the PE CXAM radar. I started with WEM's from their Enterprise/Hornet fret, but couldn't get the sides lined up and boxed in, and my last attempt broke apart from too much bending, straightening and rebending.
I had a set of radar from fstar, and it went together perfectly the first attempt. It's also somewhat smaller than the WEM, which worked out well since the kit is reportedly undersized.
I still have to weather the CXAM and attach a piece of styrene rod as a mounting pole.
Also ahead are the eight 5" guns, eight 20mm's on the starboard side next to the island, and all the 20mm barrels for those molded in shields Tamiya kindly provided.
I found some 3-D printed 20mm's from Blue Ridge that I'm anxious to work with. They arrived this week, but I haven't unpackaged them to look at them.
