3:05 if you think that the door isn't water tight first inspect the gaskets for cuts or tears and remove any paint you might find on the gasket, which is common with a careless/lazy paint detail (which is all of them). Now do a chalk test: run chalk (Marines might try to use crayons) around the knife edge and shut the door and dog it down like you mean it! Open the door and if it is correctly adjusted you find a nice even line of chalk running round the surface of the gasket. If there are gaps in the chalk it means that the dog nearest the gap is out of adjustment. You and Smitty (there is a rating on every US Navy ship who is named Smith/Smitty) need to bust out a wrench and a hammer, remove the handle and pull the dog. There are shims on the shaft: removing a shim moves the dog closer to the door and will correspondingly compress the gasket tighter. Resemble, dog the door and inspect. Success! Never mind the smoke-break. The Chief said not to take all day, so move on and speed up!
I went to damage control school in 1970. Treasure Island San Francisco had a mock up ship that could flood, turn out lights and sound like you were in a war. We were told that no one had ever saved the ship. The sea always won, it was fun and wet trying to save the ship.
it’s a simple action that addresses a bigger problem first, they wouldn’t plug the holes before preventing spread of flooding...but this isn’t as photogenic to Hollywood so gets ignored in favor of plugging holes
overhead and onto the deck is a basic physics move: it forms two diagonals, with the loads being equally distributed rather than both on the single bracing cross piece
One problem there, Ryan. The angle you cut for end sitting on the deck is wrong. As you start hammering the end against the door, the sharp point on the deck will simply push under the the brace on the deck. The end should be cut one of 2 ways: 1) So that the bottom end is at 90 degrees to the deck and square to the deck brace, 2) a compound angle with 1/2 being 90 degrees to the deck and the other 1/2 being parallel to the deck.
about one Kamizaze, and few others but very rare. One took its first shell hit in the Korean war. The north Koreans caused a few shrapnel wounds and damaged deck wood. paint etc. they returned favour with 9 16 inch shells... no more shots fired.

Is it true that a navy ships have a keel plate? The first piece of the keel laid with the date and yard weld written? A urban legend I've always been curious about.
Untreated wood burns cleaner than coated one (not sure if its makes a difference on boat) and also wood soaks up in water and swells hence tightening and closing any gaps around.
It swells up when wet, a wooden wedge crammed in will expand, tighten and lock in even more if wet putting even more force against the damage and make a tight fit.
Those hatches are the old WWII and maybe Korean War era doors. What you're thinking of is a QTD, or QAWTD if you are feeling extra fancy. Quick acting watertight door. Those didn't come about until later in the ships career
I mean I didn't work in dc or anything so call me crazy.... But the angle of the cuts on the bottom end of those wedges.... Shouldn't that angle be reversed? Looking at it it looks like the board they are braced on would simply ride up them as they get pushed back. And it looks like it's be aweful hard to nail them together as well.

Only if you can stop the marine eating said crayon

As I am a minder of small details, I love the way you guys cover off the beaten path type topics!

It's all fun and games until someone reports flooding in the superstruture
Insightful vid, really looking forward to visiting this beautiful old warship one day!

quick and informative. great details, thanks for bringing up things rarely discussed

Love all your content, hope to visit the ship one day
How much battle damage did the Iowa class battleships sustain during WW2?
Very little.
about one Kamizaze, and few others but very rare.
One took its first shell hit in the Korean war.
The north Koreans caused a few shrapnel wounds and damaged deck wood. paint etc.
they returned favour with 9 16 inch shells...
no more shots fired.

Is it true that a navy ships have a keel plate? The first piece of the keel laid with the date and yard weld written? A urban legend I've always been curious about.
Not all ships have it, but many do. The new submarine New Jersey does. The battleship does not, as far as we know.
Were the Iowa's the only US battleships to participate in Korea? i.e., the South Dakota's and North Carolina's all gone by then?
Yes they were the only ones.
Is there any particular reason to use untreated wood for the brace?
There are also metal mechanical shores but I like these better for this sort of thing, they give you more flexibility for the weirdness of a space.
they're not being used for long term repairs, so don't need to have em treated. untreated is lighter and stronger.

only need them in place for a short period of time, once they can get a crew to plug the hole they can pump the water out
Why don't those hatches have a wheel to dog them? It seems during battlestations, it'd take too much time to dog each hatch as is.

Ryan and Co. did a video that covers the different types of doors in a video you can watch here: ua-cam.com/video/DmaTJTPfXA4/v-deo.html

The trick is you have to wedge a block behind it, then it works really well
Yeah, there is no chance the shore they put on that hatch would even help a little. A nice thought, but not at all what a real shore would look like.
Love your videos.
But in this one your helper really doesn't look like he wants to be there at all.
Not everyone likes to be in the spotlight/on camera
Seams like a design flaw. The door latches cant handle the pressure?
This system is for if the door or s bulkhead fails due to an explosion or other cause
water is heavy, especially under pressure...eventually latches can give way from the pressure so the bracing takes that off
Why are historians on museum ships know more about damage control then the current war fighting navy?
Libby's explanation of the bullseye is way better...
way nicer on the eyes too! No offense Ryan!
My guess before you tell us is deck 7 comparment 111
