  Post subject:  Adding portholes to a pre-war Yorktown?  Reply with quote
Thanks for the info on the director.

Looking at plans and photographs, I have a lot of portholes to add to my Fleet Problem XX
Yorktown...

What would the recommendation of people who've done it be vis-a-vis adding portholes; is
photoetch the way to go? And, I would guess, for uniformity's sake, replace ALL the portholes
with photoetch? At one point, someone made resin-decal portholes (similar to Archer's products),
which I would have considered, but they appear to be no longer available.

curious,
Doug

Actually is is the same size rangefinder in the birdbath of the New Orleans class CA's. For LA control of the 5" guns

I was curious about the range finder on the roof of the pilothouse. Wiper refers to the other
director (AA, I think) as a 'Mark 33'.

David,

Thanks again. If I have to scratchbuild it, that drawing will help. The drawing simply refers
to it as 'range finder'... anyone know what the designation for that model was, i.e. a 'Mark __'?

curious,
Doug

  Post subject:  Late 30s pilothouse roof gunnery director on Yorktown?  Reply with quote
Another 'known unknown':

If I'm modeling the Yorktown as she appeared in Fleet Problem XX, I need to backdate the pilothouse
roof with the gunnery director that was there in the late Thirties. Comparing photographs, though, I've
been unable to come up with a model number for that director. And, going through products from L'Arsenal,
Shapeways, etc., unable to find anything that matches. Anyone know the particulars on that director, and
if there's a resin version out there somewhere? Easy enough to scratchbuild, if I had dims, too, I suppose.

thanks,
Doug

David,

Thanks! That pic taken during Fleet Problem XX, in February of 1939, really clinches it for me! I've seen that
pic before, but IIRC it was undated. I've discovered that the NHHC site is a great resource, and sometimes
has dates on pics that are undated elsewhere, as well.

cheers,
Doug

I haven't seen anything that suggests otherwise, but I'm also the one pushing a theory on no official evidence. :big_grin:



Yeah, but it's a rational, educated hypothesis ;) And the photographic evidence is compelling.

Any idea on the 'Y' on the funnel? 1940? Or, perhaps, earlier?

Hi,

After putting it off for several years, waiting for new/better sources, photos, etc., I've decided to start
my pre-war Yorktown build, using the Merit 1/350 Yorktown, a pile of photoetch, aircraft sourced from
various places, Evergreen plastic, etc. I have (at least) two questions that I was wondering if the brain trust could
help me with: (1) what year was the large 'Y' painted on Yorktown's funnel?, and, (2), I subscribe to the
idea (Tracy's research, IIRC) that the hanger deck walls/bulkheads and ceiling should be represented with a silver metallic
paint, but am I gathering correctly that the flooring on the hanger deck should be Deck Gray?

thanks,
Doug

The radar as well - Enterprise with the CXAM-1 rather than the Yorktown's CXAM.

It's enterprise Jeff. If you compare that pic to the one of Yorktown in drydock after Coral Sea, you can see the difference in the degaussing cables.

I'm no photographer, but here is a top down view of the Trumpeter and Toms Modelworks hulls shot more or less from a point above and between the two hulls. I placed the Trumpeter hanger deck piece in the hull just to make the two shots a little more comparable, but the Tom's kit has the sidewalls of the hanger deck molded into the hull and they're separate pieces in the Trumpeter kit (and obviously not installed yet), so the matching along the port and starboard edges isn't "apples to apples". Still, it's easy to see where the five inch platforms are going to be, for example, and how closely aligned they are. The relative placement of the three elevators can also be judged (though the Trumpeter hanger deck is loose and I think it will shift a tiny bit toward the stern during construction).

Thanks David for your input. When you made the comparison, which hull was slightly larger/longer? I’m assuming the longer one was the overscale Trumpeter Yorktown hull.


No, the Trumpeter kit hull was slightly shorter (in my opinion) at the waterline than the resin kit, although aligning the stern ends is a bit tricky because there's so much curvature coming down from the hanger deck to the waterline at the stern. The Trumpeter flightdeck is also slightly shorter than the resin kit (although the resin deck is in three pieces, and I haven't glued them together yet, so they were just pushed as close together as they would go on my work bench when I laid the Trumpeter deck on top of the resin pieces). Don't ask for too many more hull details, because the resin kit has some flash or over-pour at the hull waterline that I haven't begun to trim/sand yet, and which might reduce the waterline length slightly after that's done - I think the bottom was "up" when the resin was poured. Anyway, I'm not a big one for splitting hairs, and it looks like both kits would build up nicely.

The Trumpeter roll up metal doors on the side of the hanger deck look pretty good (you can't expect these to be accurate at 1/700 any more than you can expect deck planking widths to be accurate. The corrugations in the roll up doors are maybe 2-3 inches wide in real life?).

Since we're comparing: The Trumpeter hull is about 1/4" longer at the waterline than the Tamiya hull - very obvious, but I think everyone knows that the Tamiya kit is in the 1/720 neighborhood in addition to the other issues with the Tamiya hull shape.

Dave

PS The Trumpeter kit molded the bridge/stack structure as one piece (as opposed to port and starboard sides), although there are still lots of platforms, funnel caps, masts, etc that have to be added to it). I noticed this because it was one of the heaviest pieces in the box (since it's solid plastic, not hollow like I'm used to making). That, and I'm not used to seeing injection molded parts that have molded detail on at least five different sides (fore, aft, port, starboard, and top).
