For many, it's all about the size of the gun, but for me, it's the little details of how it works and the engineering involved. A terrific animation, well done.
That breech mechanism is an engineering masterpiece. Also, the graphics here are beyond measure. I am a machine designer who works in 3D CAD but I have never gotten to the stage of making animations. I am immensely impressed at the work here.
Absolutely outstanding series about RN 15"turrets. The graphics are clear and precise. Many thanks for making a monumental effort to produce this and to bring this to RUclips.
My dad sent up the cordite through the floor and up to the 15" gun enclosure. He spent the second half of the 2nd world war on HMS Malaya mine sweeping. The stories he told were fantastic and some were funny. Happy memories for me, thank you❣
Sometimes the internet gets me down, each time when looking for some obscure online information you're confronted with SO much utter rubbish and irrelevant nonsense.... and then every once in a while you stumble on something of truly OUTSTANDING value, a veritable work of art. THIS is one of those moments. This is the sort of illustration that shows me what all the books in the world could NEVER convey, and what the internet is truly capable of when used to its full potential by a master. Thank you VERY much for this work of mechanical art.
I'm very impressed with the animation graphics that shows great research and understanding how the breach works! All this was engineered with a slide rule and a lot of calculations! Good job 👍👍👍
I always thought that the breeches used some sort of a full tapered thread, and at one point was confused as that would prevent them from being opened on a swing. Stepped interrupted threads make much more sense of course :) Thanks for the video!
Great work of art! I can't believe how these stepped breech blocks were processed without CNC machine tools 100 years ago. Sir, can you make a video about how ordinary lathes can process stepped breech blocks? thanks.
This type of cut was made by specialized machines, either a milling machine that has various axes connected through gears, or a shaping machine with several axes moving at once. The magic of CNC is not that they can make unique shapes, it is that _a single machine_ can cut all these various shapes by only changing software. For example, an engineer recently made a mechanical setup to cut a scroll thread: ruclips.net/video/OqwnOn-XhQI/видео.html. Similar set-ups were used to cut these interrupted screws.
@@TheEvertw Thank you for your suggestion. I am worried that the craftsmanship of 100 years ago will disappear, and it is easy for CNC to do it. However, I have imagined a method of processing 16-inch breech blocks with ordinary lathes, which will be verified with industrial software in the future, thank you. I think 6:13S cutting speed is not high, it should be easy to process. ruclips.net/video/TowYdhn8AeI/видео.html
@@华天上 That film does not show the machining of the actual breech, just the ring to receive the breech. A stepped thread can not be machined on a lathe, because the cutter would need to jump very quickly to the different radii. But a very interesting video, thanks for the link!
There was a world full of resourceful and skilled people before the invention of the CNC. Now we have a world of idiots who don't know how to do anything without a computer. Because of comments like this, people do not believe that the Egyptians were able to build the pyramids without the help of aliens. Because the ancients were stupid, as we all know...
Very interesting! A story that may be of interest comes from my grandfather who served on a turret crew. Their gun happened to be consistantly good during firing exercises. Better than others in the fleet. Boffins (being boffins :-), found it hard to accept that they JUST MIGHT be a bloody good guns crew, and thought that the TURRET might be somehow better than others. To this end they removed the whole turret from the ship so they could find out. It was a standard turret. However, when they refitted it into the hull, they buggered something up such that a gland in the mechanism that rotated the turret kept failing. Sooo. . . They got VERY good at replacing this gland, for obvious reasons. Now:- The powers that be decided that they were going to test the abilities of all guns crews in the fleet, with regard to repairing an obscure item that rarely failed. Yup: That gland! No surprise, they aced that test as well! My grandfather (Con Cahill) passed some time ago, and I do not know which ship he was on at the time, but I believe they had either 15 or 16 inch guns. That tail has always remained in my mind! Respect to all who served, we are here today, thanks to those who are not.
Thanks for posting - very interesting story. I found a service record for a Cornelius James Cahill (born Portsmouth 1909). If he's your grandfather, he served on HMS Hood in the early 1930s. Direct link to record is below: discovery.nationalarchives.gov.uk/details/r/C14811077
@@rnbreech4194 That is indeed my grandfather! I recall him mentioning that he had served on the Hood when discussion came up about her sinking. He would talk about his peace-time experiences from time to time, but like many who served during the war, they may talk to others who have been through it, (although mostly a 'nod' to shared experiences), but if you are lucky enough NOT the be in that select group, you do not have the . . . . inate understanding that comes from being under fire, and seeing comrades die in front of you. Then, every body had some understanding, what with the bombing on the "Home Front." Today it must be a very surreal experience to be fighting one day in Afghan, (for example), then back home the next, where it is a footnote in the news. Thank you for finding his record.
Fantastic animation, brilliant work, well done for making a very complex machine so clear. I would very much like to see a similar animation explaining how the interrupted screw for the breech was machined since this must have been a fairly complex operation in its own right, involving specialist machines employing "Geneva mechanisms".
Thanks a lot. I did find the following film while researching for this animation. It dates from 1918 and shows some machining processes for breech screws. Timestamp 0:22 shows the machining of the step thread for a 4 inch breech bush - not the clearest of films but there isn't much available online. www.iwm.org.uk/collections/item/object/1060022750

excellent vedieo amazing detail down to the nuts a bolts an excellent production makes me want to go out a build my own gun and put it in the front yard to keep the neighbors dogs out!
there are 6 narrow slots in the breech screw. 1.50. that seem to align when open and closed. any ideas what they are for? Amazing looking technology and great vid :)
This is just terrific. No idea what effort it took for this animation,other than lots,but well done. Two questions,please. What is the voltage,and maybe the amperage, of the firing circuit ? I am presuming a DC generator not AC. Also,I do see the compressed air rating of 750 psi. The powder charge going off is going to be way more than that. I suppose a one way valve stops gas flow back in to the air system. Did I miss an illustration of that or did you not include that ? A ball bearing,spring and seat works for the model railroad guys,but such is relentlessly a sealing problem,thus unsatisfactory as a safety item here. Any idea what was used ?
Thanks! See link below for firing circuit diagram used with 15 inch guns: www.dreadnoughtproject.org/tfs/images/4/49/ARTS1915Plate116.jpg Voltage is listed as 15V. The air blast path into the gun chamber (09:35 in the animation) is behind the obturator pad so wouldn't be exposed to the powder igniting.
@@rnbreech4194 Aha. Got it. The Germans stuck with a length of brass cartridge for obturation, but USN and RN went with Bang system. So here anyway,there are other benefits than the immediate.

So whether a grenade in a hole,or a turret full of guys,powder gases are a lot more than just an unpleasant experience. Possibly NO,but I should have made note of it. Anyway,thanks for the reply.
