Bill, do you want a copy of the Glorious' Feb 1930 plans that include the hull sections?
I would make the bulges differently & the bow all plastic with no putty involved. take a look in this link.
1. On the evil auction site are plans by David C. Marlowe. "Simple" is a complement. His plans are about 1/400 so you'll need to scale up to 1/350.
2. Believe it or not the Lindberg HMS Hood has about the right beam. That's important.
3. The bow and stern of the Hood suck. The bow has to have stock or putty added to build it up. Get a good book on tape & make friends with sanding sticks.
4. How did I make the anti-torpedo bulges? I got two discount models of the 1/240 Lindberg Gato submarines and stole the side ballast tanks, seriously. Yes, I made anti-torpedo bulges out of submarines. The two front ballast tanks can be removed, glued together, then placed on the model, pre-sanded for good fit, glued into place, putty, and make friends with the sanding sticks.
5. Paint, check for imperfections, fill, and sand some more. (I'm now at #5)
6. Mark out the port holes, drill out, and add the deck. (note, technically the model of Glorious/Courageous has three main decks. There is the top most flight deck, former flight/storage deck, and the open lower deck.
6.5. make sure the lower deck is installed. Also, you would have to both cut down the front and build up the rear of the Lindberg Hood 's hull. I used 1/8th inch plastic card stock for the hull modifications.
7. Buy Friedman's British Aircraft Carriers: https://www.amazon.com/British-Carrier-Aviation-Evolution-Aircraft/dp/0870210548/ref=sr_1_5?dchild=1&keywords=British+aircraft+carriers&qid=1601419999&sr=8-5
8. Buy all the plastic 1/8th inch lattice that you can. You'll need it.
9. Measure out the superstructure of the ship above the deck. I still have not quite figured out how to do this. More than likely I'll measure, measure, measure and build a skeleton from the plastic lattice, add the 2nd deck, then add the bulk heads, and add the flight deck. I think this should be done in sections. Also, the stock I'm using will be very thin at only 1/16th inch. You should be able to see the skeleton of the lower hangar deck looking in from the stern.
10. I already ordered the 4.7", the Swordfish, and the 8 barreled Pom-Poms.
11. I'm scrounging every lifeboat in my spare's box. I hate to have to order expensive Shapeway's boats but will do so.
12. The "antenna masts" look way cool on British ships. I'll just eat the expense, buy some 1/400 Illustrious brass fittings, and live with the fact they are undersized.
Notes on Glorious/Courageous : The two long flight decks must have screamed "fire hazard". The lower hangar deck was open at the rear and must have been hated in the North Sea. The upper storage deck doors appear to have been permanently closed. Those two ships were as glass jawed as Wasp .
I'll be done in 2021 or 2022. When the project starts acting like work then put together a fun Esci or Monogram 1/48 Sabre. BTW, I keep on hoping Kittyhawk makes the FJ-3 Fury (not the FJ-2) in 1/48.
Sources for your plans for this conversion(?)
Not a cheap process. I cut down the deck but has to raise the back deck. A 1.5 inch pug has been added to get the correct length. Two "blisters" have been added to the hull (that was a nightmare). This weekend I go over to metro-Detroit and buy all their "lattice" plastic. The bow of Hood was reshaped with stock & putty to Glorious' bow.
In October I'll start adding the "flat iron" part of the flight deck.
The model is only going to get 12 or so Swordfish.
