Looking good Si! If the rear elevator is in the up position, and the shutters are open, do you have to build any support (like guide rails and /or the lowering mechanism)?

Hi Thomas,

I will indeed, I have some etch guides and mechanism left over from my CVL22 build which it is plan to use as a basis.

It may take a little fettling, but it should work. (I hope)


Cheers

Si

Looking good Simon.
Watching closely to see your work on the hangars. It's giving me plenty of food for thought about how to approach E when I get that far.
cheers

Thanks Michael,

I am making this up as I go along, so I would equally be grateful for tips and ideas.

Thanks Russ,

Slowly but surely mate, lots to do before the flight deck goes down.

Cheers

The missing struts on the propeller shafts added from plastic strip.



etched detail strips / catwalk mounts fitted to the rest of the flight deck.

Port aft



stbd aft.



port midships



Parts for the side elevator guides, on the fret.



The "base" plates removed.

A bit further.



and done.



The instructions for these are not the clearest, but so far so good.

More soon.

Yesterday's progress.

The structure under the forward end of the flight deck.

The to fore and aft frames and the forward support test fitted together.



The 2nd and third supports have some structure on them, the production line under way, eight of these parts required.




the fitting to the second support under way.



Beginnings of fitting the parts down.



The big bits all done, just lots of little bits to do.

Test fitted in place.



More soon.

Cheers

Si

Hi Russ,

You aren't wrong, but it's not all there yet.

Sure do, not fixed down yet. I think I will put some anchor cable in as well, the lack will be visible from some angles.

Nice to see a start on the serious metal work. As Russ said, a whole lot of brass goes into the flight deck support, fore and aft. I think the challenge will be in painting it all.

cheers

I will indeed, I have some etch guides and mechanism left over from my CVL22 build which it is plan to use as a basis.



For what it's worth, the CVs and CVLs used totally different elevator mechanisms. The CVLs didn't have the space for the hydraulic rams below the elevators that the Essex class did and used cables and pulleys to lift the platform. The Essex class had two pistons fore and aft on the elevator's centerline with a vertical track ahead and behind of them that was designed to hold the elevator flat (so any unbalance would not be transferred to the pistons with their need for tight tolerances and seals). You can see these in "The Fighting Lady" on Youtube about 5:30 in. The pistons are the bright shiny things and the track is the dark column next to them.

*Generally* when the elevator was raised a secondary, auxiliary elevator rose up out of the pit to cover part of the opening to make moving aircraft fore and aft around the elevator easier. They show up in plans such as this one but I don't know of any web resources that have photos or video showing this clearly.

Be aware that the post-war modifications to the Essexes changed the elevators out to handle the heavier and larger aircraft, so they're not good references to use.

Thank you for the advice Tracy,

New plans then, The guides are shown in the AOTS book on the Intrepid, and the secondary elevator, but not the rams. have a decent selection of tube & rod, so I will give some impression of the actual mechanism.

Missing out the secondary elevator is deliberate, to show the pit, and I apologise if I am incorrect, but would it be deployed every time the elevator goes up, even if it is coming straight back down again. The will be an aircraft, wings folded on the elevator, and another waiting to come up.

Appreciate the advise and information Tracy,

Thanks for looking in.

Cheers

Si
