That picture looks like the deck spot for the Raid launch.
Can someone help me on this: I think I remember that one of HORNET's design changes was to allow for the forward-fit of Quad 40mm Bofors to replace the 1.1" quads and so the forward two quad tubs were spaced further forward, #3 quad tub was lowered to the flight deck level, and #4 was lowered to the gallery deck. In the latter two cases, this lowered the CG. So the question is: if true, did the HORNET get built with the actual quad Bofors tubs, or the smaller quad 1.1" tubs. And what size was the tub for the Mk 44 director for each quad 1.1" for HORNET?
Thanks (Dick?)

Hornet's 1.1 arrangement was modified from the original Yorktown config to allow for the quad 40MM. However, the size of the installed tubs does not appear to have been intended to allow a direct substitution of quad 40MM for quad 1.1's. I am not even sure that the precise size of the quad 40MM mount was known at the time Hornet's tubs were fitted. But it was the anticipated size of the mount, rather than topweight, that lead to the repositioning of the #3 mount from the top of the clipping room to the gallery deck further aft. A tub large enough to accommodate a quad 40MM would have interfered with the operation of the large crane, so it was moved. When Enterprise upgraded to 40MM, her #3 quad was relocated as well. But in the big 1943 refit, a twin 40MM, with the same footprint as a quad 1.1, was fitted atop the clipping room. Sorry, but I don't have the dimensions of the tubs for the MK-44's.

Dick -
Thanks for the reply. I was pretty sure you'd say the tubs installed on HORNET were not the quad Bofors' size because the blueprints show a smaller diameter for the 1.1" - by more than the thickness of the drawing pen - when compared to Bofors tubs I have laying around. Was hoping I could use the clip racks inside the Bofors tubs in the 1.1" tubs for detail effect. Some pictures showing 1.1" clip racks may be more like a shelf than a perforated rack, one ammo clip per hole. Any thoughts?
Am really getting into the weeds I know, but am making enough progress where I have the biggest things done or figured out, and the smallest ones remain. I am smooshing several manufacturer's products together to get to HORNET, and they do not all agree on size and fit requiring some crafting at every turn. (If only Merit would do HORNET. $#1^!!, but I have heard directly from a Merit source why they probably never will.) For the record: hull carved from BWN resin (tried several other ways to get accurate hull first, spending lots of time trying to save time), A lot of the Merit YORKTOWN kit (found Trump kit totally unusable for my purposes), Model Monkey island w/o catwalks, P/E from Pontos, Infini, various 3D printed AA weapons, lots of scratch-changing of parts.
Endeavoring to persevere.
John

Does anyone have a more accurate picture or information on this bunker hose support? Is it an articulated arm?

My project:

The primary purpose of this structure was not as a hose support. It was one of 10 "outriggers" that were designed into the Yorktown class - 4 to starboard and 6 to port. The actual purpose was to support the tail wheel of an aircraft. The outrigger would be positioned perpendicular to the deck, the tail wheel would be attached to a slide on the outrigger and then the aircraft would be pushed back until the tailwheel reached the end of the outrigger. This increased the deck-spot capacity of the flightdeck and allowed some "ready" aircraft to be stowed out of the way of the remainder of the deck load. The numbers of outriggers were reduced as the 20MM fit was increased and eventually, all were removed from Enterprise. Yorktown and Hornet still had a few when they were lost.

Ok, Thank Dick!

I remember this system, I must have seen a photo some time ago. I only found this picture of the USS Intrepid, I'll look into it.

I can see from your work that you are a man for detail and I thought you might like this...

Thank you, it's the picture I was missing for the pivot axis. :thumbs_up_1:

This outrigger is drawn, I simplified it a bit due to the constraints of 3D printing at 1/200 and my railings already in place.

Tks Guy's! :thumbs_up_1:
