when i get stuck working on my backyard battleship this is where i go for advice
Bawahahahaha
Me too 😂
Yeah my neighbor keeps telling me to move mine as it's blocking part of their driveway. 🙃
Same here but only after a week or so has passed while I stubbornly tried to do the job all on my own.
*heading to Harbor Freight for a socket set and PB Blaster*
I'm waiting for the day when Ryan says the museum has partnered with Haynes for an Iowa class repair manual.
Haynes does have a battleship manual "Battleship Bismarck Manual". For US naval vessels I could only find "US Super Carrier Operations Manual"
I've got one for the Klingon Bird of Prey, so why not?! 🤣
I'd buy one.
@@target844I've got one for HMS Victory and all Royal George Class 104 gun First Rate Ships of the Line... I'd find it very useful if I could find a 2nd hand one! 😊
Yes, it will be in (49) volumes.
"hopefully this video can help you out when you have your own battleship at home"
That's good summation of the endless "bring her back into service" discussion.
'Yeah, just build your own!'
Sounds like an instructional video from Troy McClure.
I don't think I've ever seen Ryan happier than when he was holding that battleship-sized wrench.
"can i have a battleship?"
"only a wrenchfull"
*pulls out comically sized wrench*
Thats a slugging wrench i had my share of a hammer and swing lol
When I was an ironworker we called those knock wrenches. My granduncle was a merchant Mariner. He was an engineers mate early in his career. He told me they used those wrenches and sledgehammers to tighten bolts and stud nuts. Torque was either measuring the bolt stretch with a dial indicator, or snug plus a certain number of degrees of rotation
@@harescrambledIn Australia they're called flogging spanners.
@@hoilst265 Slogging spanner in the UK. Used a lot for plumbing.
The picture of the battleship in the floating dry dock is the USS Iowa at Manis Island during WWII. My father was there and assisted in putting it in. Big event for a 18yo Iowa boy.
So cool that a boy from Iowa was involved with the USS Iowa. I've toured the Iowa multiple times and these videos about New Jersey add much appreciated details to what I saw, and to what I didn't see, like these prop locks.
Now I know how to unlock the propeller shaft on my battleship. Really helpful video for do it yourself battleship maintenance.
For some fun support undo the couplings at the engine/gearbox, remove the locks and let those props spin. Perhaps some support stands with rollers for the loose end of the shafts so they don't flop around.
I am 55 and a Disabled Veteran, as a kid I visited the USS Alabama many many times and I found battleships facinating. Visiting the NJ is a bucket list thing for me Ryan and I wanted to thank you for making these videos. Best of luck during drydocking.
I’m 72. My wife and I visited the Alabama in June of 1974.
At that time, there wasn’t much to see or do. Almost everything was off limits.
Has that changed?
@johncox2865 My dad is 78. We're riding down to the USS Alabama on motorcycles this weekend. He hasn't been in over 30 years. Lots has changed since '84 when he first took me. But a lot has remained the same.
I remember sleeping on the USS Alabama on a weekend long Boy Scout trip in 1991. At the time they were filming "Under Siege" on it so some of the super structure was off limits but late the 2nd night me and another scout went exploring. It was raining all night and we went into a bunch of off limits spaces by ourselves. We were constantly afraid of getting lost and entombed on the ship and there were some really deep areas we wanted to go down into but the flashlights we had were shitty. I love the Alabama and I have not been to it since the '90s and would love to go see it again.
I@johncox2865 it's been better than 2 decades. When I visited. You could go almost all the way to the keel al the way up to emergency steering control, was a bit of a climb. Don't really know if what I did was actually legal. Visited during a week day, not only very many people around to tell me no. What few "Experts" that were there, didn't really know no much about anything.
Thanks for your service sir!
That shaft lock tool is called a Slugging Wrench. They tie a rope on the handle for one guy to keep tension on and the other guy smacks the wrench handle with a sledge hammer. The rope keeps the wrench from bouncing off or moving out of position.
I just watched Kindergarten Cop and in a scene with the bridge in the background at Astoria, Oregon, the USS New Jersey can be seen for a brief moment heading out to sea. I promise you there were no shaft locks engaged. The movie was filmed in 1990. I got so excited that I saw a battleship that I paused the movie and did a search and found that it was the New Jersey.
New Jersey was paid off in 1991, so that footage was probably taken one of the last times the battleship left port.
ah, the good ole Slugging Wrench. For when the torque spec is "hit that motherfucker one more time"
Flogging spanner .
in the uk we call it a flogging spanner
That wrench seems like it should end up on display on tour route, also would keep it out of a place prone to having condensation on metals, possibly get some rust removal and fresh paint to prevent further deterioration too.
or oil as a functional tool
Probably better to keep it near what it is intended for. Out in the open items can end up misplaced or stolen.
After 30 or so years sitting in the same location it seems to be in great shape.
Other than the history of that being the exact wrench thay did the job, it's an easily replaceable tool, and I'd be willing to bet it was accidentally left there. It's not a tool specifically made that is only used on battleships so I'm betting it was from the common toolkit for whatever unit mothballed the ship which means someone probably got yelled at for losing it
Very often aboard ships, tools like that wrench that have a specialized "purpose" are bolted or hung on brackets on an adjacent bulkhead. I have over 20 decades as an engineer in the merchant marine and for instance, on my last ship we had shaft locks and wrenches very similar to those in the video. I never saw them used, but both the lock and wrench were painted bright yellow and ther wrenches hung on welded brackets made for that purpose. The bolt holes in the shaft locks aligned with welded studs on the bulkhead and were secured with nuts (not same size as the shaft coupling bolts). While hardly, if ever used...they are readily available if needed. I am suprised New Jersey doesn't have a similar set up, but do understand why the wrench was located close by.
Reasons I like Ryan:
Passionate and knowledgeable about the museum in his charge
Drops maintenance tips left and right, which is important to me as I have a 1:1 fully functional replica of USS Kearsarge BB5 in my back pond and need this kind of thing
Says things like "chungus" and "these nuts" in videos
6:44 "You might ask..."
That's your basic "knocker" wrench. There's a sledge hammer looking for that wrench somewhere. We used those to break the couplings on large steam turbines in power plants for years. At least until they bought us our first Hy-Torque wrenches. Nothing like a hydraulic wrench to make the day go better.
Also sometimes called slugger wrenches
USN called them slugging wrenches. The problem was room for the sledge hammer and room to swing it. "Torque" settings by ear. When you couldn't get the wrench to move with a decent blow, it was torqued correctly. Practical technology.
Flogging spanners in Australia and probably the UK.
hy torques are cool and we still use them, but have you ever seen rad guns or hydranuts?
Okay,, I'll bite. Do you have a picture? I'm old tech. A trailer with a decent air compressor and a 1" drive impact wrench. Pull the trigger and if you could ride that thing for 8 seconds, you got take home the trophy. Practically, once the nuts were removed from the flange bolts, that didn't mean the joint would come apart. Now we needed a parting wedge, some come-alongs, and sometimes the realization that the night shift would arrive in an hour. Let them handle it. @@patrickwhitehead7584
Your channel and Troy McClure's "Mothball Your Own Battleship" have really helped me maintain my battleship.
"Hi, I'm Troy McClure. You might remember me from films such as 'Screw that Shaft' and 'Do you see torpedo boats?'"
@@hawkeye5955 * throws binoculars into the ocean *
It took you a while to find it, but through the magic of video editing we are instantly shown the results of your search!
This is one of those things about museum ships I'd never considered.
The "Pc 3" probably stands for "Piece 3" is how it was numbered on the yard's paperwork and drawings for the work on that coupling.
It is interesting that the nuts are also stamped NJ, as if there would be other battleship shaft coupling nuts lying about which might get mixed up with these. 😊
@@wtmayhew Maybe for the inventory control at the nut farm ...😂
@@donalddodson7365 Well stated.
@@wtmayhew I'd wager that those nuts are individually tested and certified to a high strength rating, so they'd have to keep track of where they are intended to go.
@@Orxenhorf Thanks for the reply. I believe you’re correct. I was making a bit of a joke there. It is better when everything is documented and nothing is left to chance. That is how to do quality work.
Yes, that's called a striking wrench, it's designed to be hit with a hammer, in the case of something this size it would usually be a sledge hammer. I used to work on rock crushing equipment, the crusher jaw bolts were even bigger than those and there was no room for an air impact wrench so the only way to get those loosened and tightened was putting one of those on the bolt and hitting it with a sledge hammer. And if the strike was not perfectly straight the wrench would go flying and end up is some awkward place inside the machinery.
A good job of Detective work Ryan ! Your knowledge of the ship grows by the day. Those steel locking plates look to be of 5/8" steel flat stock with good edge distance where drilled for the flange bolts. Just fits the old adage " Built like a Battleship ".
I know it's a pipe dream that would take INSANE funding that these museums don't have.... not to mention hundreds of volunteers and an armed security detail... but it would be so cool to see one of the four sisters move under her own power again and do some grand tour of the US and the outlying US islands.
Still, seeing the care the Navy took in putting her to bed is kinda sweet.
I love your idea I wish they would do that too but just as you stated it would be an insane amount of money and a lot of volunteers to make something like that happen but it would be cool.
My gues$ is one billion to just get a SoDak underway, another billion to do it safely and reliably, and another billion fully battle ready. Maybe 40% less on the Iowa's? The stuffs dreams are made of 🇺🇸
It’s in the agreement with the navy, that the ship can never be moved under it’s own propulsion..the Navy either removed or disabled components that would allow the ships engines or propellers to be activated..
Yes the Navy disabled her, in many ways, but listening to all the videos shows me she CAN be re reactivated if the need ever arises. It's like a long term insurance policy. It's there should you ever need it. I know the cost would be astronomical, but it can be done. I wonder if the Navy has a program in which Battleship-Era sailors are training select current or more recent retired sailors in the operations and maintenance of the Battleships. I also wonder if the Navy has stored away in some warehouse a full parts inventory for them including bags and shells for the main 16" guns. It wouldn't surprise me with all of the classified programs the government keeps.
@@Firefyta2 thing is to start up the NJ you need a trained boiler operator like myself. Now I’m a bit rusty but I can read and understand a steam engine manual. I’m 42 and probably among the last generation who understands how they work and operate. As a ship NJ probably uses higher pressures and probably superheat. That’s the kind of long term wear that’s got to be factored in cause you technically can’t shut off a boiler if you want to get it running right away. At Pearl Harbor does anyone remember the USS Nevada story? Nevada had several of her boilers still online, this allowed her to get her plant up and operating significantly faster than the other ships and it’s why she was able to get moving. NJs plant would require a significant inspection given it hasn’t run in 50 plus years. The boilers would need new everything and probably a computer to control the combustion of so many individual burners. Next would be fuel oil and a system to filter it and finally replacement of the trunking for the combustion or exhaust trunking to carry it out of the funnels. Boilers are a tough thing to keep running perfect and the computer would be vital to balancing NJs multiple units. Even with computers running certain aspects of the boilers they need constant attention and watching. A steam engine is a living thing
It is always fun to see ship size components. My roommate’s uncle worked at the yard in Virginia Beach in the 1970s and we went down from Fort Meade to visit. They had an aircraft carrier and a nuclear submarine in dry dock. The sub looked like a toy compared to the giant carrier. The machine shop was amazing. They had a bronze propeller with 12 foot blades up on a stand for balancing and well as huge lathes, etc. It felt like the Jolly Green Giant’s workshop.
Subs in dry dock are surprisingly large. But in comparison to carriers, they are toy boats (that also goes for the reactor capacity difference). Carriers are just a different definition of huge and having horse power rated in the millions....
@@goldenhate6649 Yes. You summarized what I was getting at. The scale is off the charts.
Remember lads always lock your shaft.
I'm good with mine in a cage and locked.
I always keep mine solidly locked in the proper docking configuration.
The wife has my shaft locked and in dry dock or is it moth balled? I can never remember!
Had a girl that insisted I do the same once.
If not, you will get shafted good and proper.
Ryan, the New Jersey holds a special place in my heart. I served on her during a training exercise in 1985. I visited her in Camden a few years ago. Thank you for preserving her and educating us on her history and amazing achievements.
I worked in a small boat yard and we built tugs that got to escort the USS Missouri from Bremerton, Washington to Hawaii. That was a special moment. Thankful for all who have served in our military and all who serve to keep us safe! God bless the USA! 🇺🇸
I've started construction of the USS Szymanski in my basement. I'm glad I have these videos for reference. It's been a real life saver. It'll be 1st in line of the Curator Class Battleships 😂
The UK Hecla class survey ships actually had a spare shaft in the engine room but a hole had to be cut in the hull to get em out
Makes perfect sense. Must have been some admin person who came up with that.
@@foamer443 If you have to replace the propeller shaft, cutting a hole isnt that much more of an inconvenience. Much more inconvenient it would be, if you had to wait weeks for a new shaft to arrive while you're on the other side of the big pond.
Be that as it may, if this was such a good idea why was this then not a uniform practise?@@Ganiscol
Not that a big a deal! Better than getting one sent halfway round the world in a UPS "jiffy bag" and then try to get down into the hull! @@foamer443
I believe they only prepped the Iowa to be able to sail to the west coast for the permanent repair and replacement of the shaft. The floating dry dock just locked the bent shaft and Iowa returned on 3 shafts.
dry dock was to remove the prop on the bent shaft
Literally called a "hammer wrench". Awesome find Ryan!!!
"Impact wrench?"
"Propeller axel #1 is seven sections long, don't quote me on that." 🙂
Also, if you hate acronyms there are two areas you should avoid:
Military and software.
Very cool, Ryan! IMO there's something very 'Star Trek TOS' about that inboard propeller shaft alley, the way it just goes off into the depths of the tail end of the ship.
If you thought finding the nuclear tomahawk permission to fire keys was a holy Grail, try finding the cotter pins that would normally go on those nuts if the locking plates weren't there? All the other nuts have a cotter pin that locks the nut in place so it doesn't vibrate off, and those cotter keys would need to be reinstalled if the locking plates were removed. It looks like the locking plates are thick enough where the nuts don't seat fully to allow the cotter keys to insert through the stud
I've always thought cotter pins were largely disposable.
@@russellhltn1396 They are a "once and done" item. Once you bend the tangs over, they are finished. Straighten them and you will be lucky if you can get them bent again without breaking.
The bigger the cotter pin the less it can be reused, these would survive a couple times ✔️
No cotter pins on those nuts. You tighten them and they stay put, a hole drilled in them would compromise their strength
Talkin' bout Shaft...and we can dig it
That rift will now be in my head for days.....
"Hopefully this video helps you out if you have your own battleship at home." 😂 Trust me i would like nothing more than park an Iowa-class battleship on a massive trailer next to my house. It would really make my neighbours jealous.
Hell yeah they will spin. That thing was built back when people gave a damn. I have no doubt it could sail.
Oh my god you are a riot in a safe for work manner! Teach me in your ways!!
I have the USS Hornet in my back garden and while it’s different as it’s an aircraft carrier, this video should carry over. Thanks!
Watch out for that Hornet. It really hurts when they strike. 😁😁
Good to know! Hmm need to add a big Sawzall to my steal and hotwire Iowa kit and thanks for having the slugging wrench handy Ryan.
Was just thinking NJ is well and truly locked down, ain't no one gunna 'jack her off the pier.
Thanks to your great tuition, my own battleship is progressing well. The people next door love it.😊😊😊😊😊😊😊😊😊😊
I was onboard the USS Massachusetts a few years ago. I was in awe at the amount of engineering and manpower it took to build this ship. I’m a welder and fabricator. Ive helped to build a few stone crushing and screen plants so I have a clue what it took. Just amazing
This was my home for 4 years in the 80's crazy
What rank ?
I wasn’t understanding how the shaft stop steel bracket was stopping the rotation until I realized the entire gray shaft and coupling all spin together! Those are big mammas! lol
thought the same. Thanks for pointing it out. This also answers why there is a red stripe on the casing so the shaft can be seen moving.
Getting tangled up in that = zero change to ship's speed 0.0
@@skipmountain9283 Which is why it had that protective cover over it he mentioned them removing to install the lock.
My grandpa would of loved your battleship, I think this stuff reminded him of ww2 and it might of sucked going to war but he loved being there in the ships he served on as a chief naval engineer. Great job on your battleship and your team that preserves it.
You do an awesome narrative. I've watched them all and need to binge watch again.
A vid on odd or large specialty tools for the battleship would be cool.
Awesome video Ryan. I don't know what if any Australian navy vessels are kept as museum ships so good that some great examples of US ones are still around.
HMAS Diamantina (River class frigate), HMAS Vampire (Daring class destroyer), HMAS Onslow and HMAS Ovens (Oberon class submarines) are preserved and can be toured by the public.
Plus HMAS Castlemaine (Bathurst class corvette) and HMAS Gladstone (Fremantle class patrol boat).
@@nerd1000ifyvisited ‘Vampire’, would recommend!
On Feb 9, 1984 when the New Jersey started Shore Bombardment I could understand how someone seeing that during WWII would think nothing could survive. That was one of the most terrifying and awesome thing I’ve ever seen.
My Company Commander in navy boot camp, was the Master Chief of Boatswains mates of the U.S.S. New Jersey. We were his first company of recruits, prior to his retirement.
You ought to stay in touch with the group website of former Philadelphia Naval Shipyard Workers and ask some of the old yard workers about things like this . I'm sure someone there remembered where the propeller shaft locking devices were installed prior to New Jerseys decommissioning or could tell you what other preparations may have been done before releasing her.
The ship was decommissioned in Bremerton, do they have a similar website?
@@BattleshipNewJersey Don't know , I worked @ PNSY . PNSY has the Drydock facilities directly across the river. Ask Bremerton ? No one did more work on BB-62 than PNSY so why not ask them ? You have real people with actual docking experience right here so why mess around ? Who is contracted to do the work ? I'm sure the procedures that we employed for the the mothballing of the USS Wisconsin and the USS Iowa were similar to the ones used on the USS New Jersey plus things like keel block placement are the same for all four Iowa class battleships.
The easiest way to define the differences between ships of a class is which ones were built at which yard, there are some major differences between the yards and how they do things. Each of the Iowas was mothballed very differently, thus Iowa being able to rotate a turret and we cannot.
What i would like to see is these ships made operational again.
These videos are absolutely fascinating
My father served on the battleship USS New Jersey in the Korean war from 51 - 55 and was a Seabee. He told us kids he was one of the crew that during drills would go down and wait for instructions on which way to steer the ship manually and how many degrees. This was incase they lost control from up top if the steering was damaged. After he received the command he had to repeat it back. The cannons had to be set atleast 15° from horizontal otherwise it would shear it off the deck. I believe he said it could take five packing which shot the missile the farthest. I've been wanting to take a tour of it and if there still there lay in his bunk.
I'm going to hazard a guess that the reason the fasteners are labeled is that they're of a special alloy, and they didn't want that hardware to be taken off and end up used somewhere else. Since they're labeled as something special it should be easier to both confirm that what's on the shaft is indeed rated for the application, and if the hardware was installed elsewhere to see that it was.
As for the second shaft-lock, that looks similarly to how a "motor plate" is installed in a race car. Instead of using soft motor mounts, they'll install a huge piece of plate steel between the engine and transmission using the bellhousing bolt pattern. This plate can be attached to the race car in many more places than conventional motor mounts. The car feels the full vibration because there's no isolation, but it's not going to come out short of the entire car being destroyed.
Elephant ears
I'd wager a guess more that they're labeled because the US military has an absolute obsession with labeling EVERYTHING they possibly can.
How do I know?
They tried to label me at MEPS when i enlisted in the army. The only reason they couldn't was because i broke the tattoo gun and told them no.
Ship’s propeller shaft bolts are machined (ie fitted) to the specific hole in the couplings and aren’t interchangeable in another hole - or at least the modern navy destroyer ones aren’t.
You want the shaft locks to be secured to something meaty enough to prevent turning - that way the tidal currents or even the way caused from being under tow could cause the propeller to free wheel and without lubrication could wipe the line shaft bearings, main reduction gear and LP & HP turbine bearings because they are all attached and spin at the same time. That also why they don’t engage the turning gear so someone can’t accidentally turn it on with no lubrication and cause the same damage.
Those prop coupling fasteners may be balanced to be the same weight, hence the marking to ensure they don’t get lost and replaced with some random nut that could throw off the balance.
At only 200RPM max I doubt the weight of a few nuts would be enough to make a difference on something that size, and when the shaft itself weighs several metric tons. That's only a little over 3 revolutions per second, not fast enough for the centripetal force to make a difference.
@@rudolphna54 you bring up some very good points. I wasn’t sure how fast the ships screws were turning.
Great Job at keeping history alive!
Thanks this information really helped me with my backyard restoration of a battleship.
Is there anything on the ship that is still classified that you can’t show or have been asked not to?
I know its covered later, but rooms such as radio rooms are classified one rating above secret clearance, can't remember what the rating is called (been awhile). The equipment in those rooms is what is considered secret, so they always remain classified.
There’s an excellent chance that the Tomahawk Missile Control Center is still classified. The Navy still uses these missiles on warships today.
Years ago you touched on forward diesel in the catacomb video. Perhaps you could get into the detail of aft diesel and how everything is arranged around the shafts? Thanks Ryan and Libby. You keep things interesting.
The New Jersey is a beautiful-looking ship. I was aboard the Heavy Cruiser Saint Paul CA73, just off the DMZ of Vietnam
when I saw her for the first time. The New Jersey was our sister ship. When we started our tour in the area of the DMZ
the New Jersey would leave and (typically) return to the US. Thanks for keeping her safe.
Got to call in a fire mission from the NJ when it was offshore of Vietnam when it was there a short time. Awesome when those shells came over. And the effect was nothing short of devastating
The stern tube shafts do not use a flange like you are pointing out, they use a muff coupling - look it up. One of the viewers stated the flange couplings are welded, they are not. The flange bolts are a precision taper fit type, hence the specific identification. That wrench is called a "slugging wrench" and is a common size and type, nothing unusual about it. Nowadays a hydraulic bolt tensioner or hydraulic torque wrench is used instead of a slugging wrench and sledgehammer.
I'd like to ask if the shafts are solid or hollow and also does the flange come off to slide shaft out of the hull?
The shafts are hollow. A hollow shaft is stronger than a solid shaft of the same weight - which would be much less diameter but weight was more important for many reasons. The flange is not removable, it is forged as part of the shaft itself. The tail shaft (or stuffing box intermediate) will have a muff coupling that is removable so the shaft can be pulled inboard to remove if a removable coupling is not fitted forward of the stuffing box but none of the videos show or describe the current configuration. It is possible that NJ shaft is pulled forward and since that part of the shaft is relatively short it is possible that it could be removed without having to cut an access hole in the skin or decks. Considering a shaft replacement or repair is a major task requiring heavy shipyard work and time, cutting a side port is very likely. The Navy has records of the Iowa shaft repairs somewhere waiting for a researcher to definitively answer the questions.
@@oldtugs Thanks for the info and helpful for this old guy. I did figure they are probably hollow for reasons you state but never knew. I did look up the Muff Coupling and found them very interesting but still wasn't sure if we are looking at a muff coupling. I was a fresh air snipe so never made it down to the engine room on the USS Vulcan, Building #5.
The video does not show a muff coupling, only flange couplings. If you look at photos of the outboard shafts you can see a cylindrical object a few feet from the hull fairing of the stern tube shaft. That is a muff coupling that connects the tube shaft to the tail shaft that is connected to the propeller. The muff coupling allows the tail shaft to be removed aft without disturbing the strut bearing and the tube shaft to be pulled forward. A flange coupling can not be pulled through a stuffing box and stern tube, it is too large in diameter. Be careful when listening to some of the descriptions on these museum ship sites, this one is better than some or maybe even most but still suffers from a desire to put a video online more than a desire to spend the time to research the topic and provide valid information. The real value to viewers lies in the details and the history behind the what and why that is so casually ignored. It is a real disservice to the viewers who come to learn something about the technology because the presenter is almost always lacking in the subject matter knowledge or experience required to provide reliable information. I wish that museum ship organization would develop a set of standards to ensure the technical content of videos is beyond the level of fund raising clickbait. The role of a curator is to help people understand what they are looking at, and that is, sadly, rarely the case in the museum ship fraternity.
@@oldtugs I don't think the IOWAS have muff couplings.. If they let us down by the stern tubes on WISCONSIN I could go down & verify. I was on a RORO merchant ship back in the 90's that had a muff shaft coupling and that ship had a pretty small stern tube seal assembly - but I've been working navy vessels since 2005. On the FFG's & DDG's I've docked they had flanged propeller & stern tube shafts. The stern tube assemblies are large enough for the flange to come through. The stern tube & strut bearing assemblies (hard rubber staves in split bronze holders) also come out which gives you a little more room to work. As for the what the cylindrical object that is a few feet from the hull - If the navy shaft design holds consistent - that is the mating flange between the propeller shaft & the stern tube shaft - which is then encased with a watertight enclosure called a rotating fairwater and it's shaped like a football. It's watertight so the flange bolts don't corrode. Also - if you see any BB drydock pictures from astern you'll see the rudders are just inboard of the two inboard propellers so once you take the propellers off the propeller shafts should slide right past the rudders.
I love how you’re STILL discovering new things. How long are the individual pieces in the shafts? Are they all the same length? Would the ship be launched with them in place?
There's a photo of the ship on the blocks prior to launching with the shafts clearly visible but the screws and rudders not yet installed. So it definitely launched with the shafts in place. navsource dot org/archives/01/062/016232 dot jpg
Never launch with shafts and props in place, lest they hit the bottom and get bent...
Id like to see everything unlocked and the boilers fired up!!
Watching these videos is time well spent
By the way, that kind of wrench designed to be hit with a sledge is technically called as slogging spanner.
They got a ton of different names, this is the fifth different name I've seen in this comment section alone lol.
@@thecrowcook that is usually the case.
When my old ship went into drydock, I was in charge of inspecting the zincs, installing a new corrosion monitoring system, and supervising the install of a few new pieces of gear - a log, and (i think) a depth transducer. Everything that had to hold back water was bedded in 3M 5200, applied by yours truly. White-knuckle frightful time when we went back in the water, if anything leaked it was on me. I would love to see some details on underwater fittings, any electrical? And is there anything making water currently that will get addressed?
From the UK have really enjoyed this series of this beast
This was very helpful for working on my backyard battleship! Much appreciated!
the wrench you found is called a hammer wrench they will take nuts off that even an impact will not do
I've heard the Navy is rethinking bringing back the battleships since the shells are immune from electronic jamming.
There's no way. They don't have enough people with the expertise to run them, and they are horribly inefficient with resources and would need tons of resources to even get operational, not that they'd be worth much against modern weapons. These were made in a time before guided missiles. This meant for it to be attacked, it would either have to be attacked with a long range shell, or a bomb dropped on it by an aircraft. Guided missiles changed all of that, making these old behemoths pretty useless except against other things of the time period. The next great war won't be like last wars. It will be swift and decisive. That means things will be attacked by missile like dams and other critical infrastructure in key areas, almost simultaneously.
The last time we had an all out no holds barred war, the world was very different in many ways. There won't be creeping engagements, it will be all or nothing, as swiftly as possible, because things are much swifter these days and the world is much smaller due to technology. Back then if you wanted to attack something, you needed to either fly planes on a suicide mission across the ocean (Pearl Harbor) or send a ship on over to attack it, which could take days or weeks. Now missiles can be sent around the world in minutes and hours. That leaves no time to hit something and wait for a response, because you know there will be a response that can come from almost anywhere at any moment, targeting any number of things.
The next great war won't be about invasions or on the ground manpower either, it'll be solely about decapitating leadership and everything they rely on, as swiftly as possible, while crippling civilian infrastructure at its core reliances. Especially when we're talking countries that have huge population disparities. If an attacking country is 5 times your population, you need to at least take out more than 5 of theirs for every 1 person, and that's just to break even, which they can sustain in the long run. Which means what's really necessary is 10, 20, 100 times per 1 of yours to actually win, which means bringing devastating force to bear, as swiftly as possible. You simply can't achieve that with a slow roll war where each vessel has to win 100+ battles to have a chance at victory, because no vessel really lasts that long.
Never :/ (But watch 'Bismark' by Sabaton as a tribute to these mighty ships:)
@@peoplez129 no offense, have you met our government?
Excellent! Informative information.
I'm sure you've been following Texas' drydock, LOOK SO GOOD NOW. I can only hope Jersey come out as good as Texas, looks like a brand new ship, hope you guys have a drone to film the process, I love the shots from Texas, so neat to see the repairs underway.
I've fallen behind schedule with my backyard Iowa class build. My backyard is about a mile away from any significant body of water, but the darn Corps of Engineers won't give me permission to dig a canal so I can float my battleship there. I'll keep up the pressure campaign though.
Just cut the shaft before the lock and boom you got screw rotation!
Fascinating, keep up the great work. Thank you Ryan!
Thank you for the tutorial! Been looking for this video for years! This was perfect guidance for loosening the shaft of my battleship.
I want to see a battleship modernized with nuclear powerplant, all the bells and whistles in electronics and auto loaders for every gun and then in action and operating. Now that would be a sight to behold.
Honestly I'd rather see a brand new BB, I'm not sure exactly how effective it'd be and I believe there are problems with nuclear reactors and the shock from firing something like 9 16 inch naval cannons but it's certainly doable if they navy had a role they needed filled that was worth the money.
My vote is Big Mamie just like ,,, say ... steaming out of Bremerton in '44. That would be Amazing
@@skipmountain9283 yeah, that would be a sight worth seeing. But picture it with a modern power plant, modernised guns, GPS navigation and targeting system. Completely automatic loading systems every bell and whistle of new and improved doodad that one could mount on it without changing the looks. I think that also would be worth watching while set's out to sea.
@@skipmountain9283 sorry I was repeating myself here. To my defence I answered while on the toilet.
Didn't you watch the movie? No high tech to jam
Are you planning on being open the day before you're pulled into drydock? I'm hoping to get down there to watch the pull.
That picture of the Iowa in floating drydock is so cool. I assume none of them have been preserved, but I think a mobile dock that can accomodate the largest battleships ever made is almost as cool an engineering effort as the ships themselves.
Take a bow, dude who did that welding. Nice work.
I want to see the captains quarters.
Me: I need a wrench.
Dad: What size?
Me: 7.
Dad: 7mm?
Me: No, 7in.
Dad: Dafuq you working on.... a battleship?
Me: 👀
This is beyond cool. Lets get a few thousand people together and get the Battle ship working again.
My late Step Father spent several week adrift in the Pacific in WWII with a seized up prop shaft on a Liberty Ship that had been converted into a water distillery. It was single screw ship. They got it fixed and spent the whole Pacific campaign following the Marines island to island making water and had 4 .50 Cals for on board defense. It was a tough war for him with very little time off ship and they had Kamikaze attacks at several points. He mustered out at the end of the war, got on a train back to Texas, and never went to sea again. My mother wanted to go on a cruise but he would not go.
A lubricated shaft is a happy shaft.
No puns intended lol
Have you shown how the 5" gun mounts are locked into place or the 16" gun turret locks?
Yes there is a video on how the locking pins on the 16in turrets are welded in place
on the Iowa, they actually got turret 3 to rotate again! they posted a video on their CZcams site last year
Ryan has the best job in the world. HEY RYAN! If you fancy becoming a hill farmer on the Scottish Border I'll swap! 😂
I had the pleasure of working the USS New Jersey on the final refits at Ingall’s Shipyard in Mississippi. Also went on sea trials on a four battle ships. Very interesting. The piece on the deck is the coupling guard for safety during operation.
Fun fact the tool he holds at 7:16 is beeing called ``Schlagringschlüssel `` in germany ! I know cause i used to be a mechanic working with these!
"Brass knuckles wrench"
Since you're gonna go into a drydock can you do a short video on how much asbestos is still on the ship? I see the signs every now and then (right above your head here actually on the shaft...) and I'm always concerned for your health being in those rooms.
as long as the pipe lagging is not disturbed, it poses zero risk.
@@leftyo9589 pipe lagging, boiler insulation, floor tiles, switchboards, and the list goes on...
Very interesting, many thanks!!
Ryan: I was assigned to the shafting engineering group at a naval shipbuilder in the 1990s. IIRC, propeller shafts were machined on lathes that were about 70 ft. long between centers so that's the longest shafting section that can be made. If there are longer lathe beds today I don't know about it. The length of shaft section is also limited by the size of ingot that it's forged from. Any number of "sticks" can be bolted to make a shaft line, limited only by the torsional stiffness and strength needed for the application. Pillow blocks spaced at the appropriate span will support a long shaft line and keep it nice and straight. Think about old-time freighters that had the machinery amidships. They had long, slender shafting, and they worked just fine.
I think the shaft lathe at BAE (formerly Norshipco in Norfolk might be longer than 70 feet or is about the same. I know they do navy shaft work there & I’ve had 55’ shaft sections in their lathe getting sleeves replaced & new fiberglass wrap applied. Amazing to see!!
TMAS. Too Many Acronyms Syndrome.
Initialisms are superior
Really neat history of the USS NJ.
Super cool video!! Thank you
You guys take Great care of that ship. The drydocking and repair of USS Texas and the recent drydocking of USS New Jersey indicate that these ships are in the best possible hands. Thanks!
Tried starting my new preloved battleship I got for cheap off eBay this morning it didn't quite turn. So happy to find your video now I know what to do!
I would love to see them move again🎉
Ooooohh that wrench is so cool!
Im really glad Ryan found the wrench, because yes, I was wondering
I really needed this one for getting my Iowa class battleship back to sea worthiness
Ah, thanks, I have an old battleship that I've been trying to get running again but the engines have been jammed up. This is immensely helpful.
The old sonar tech deep in my brain from 3 decades ago can still hear the sounds of props turning.
Very Interesting Thank You
