Internal workings of Royal Navy battleship 15 inch gun breech mechanism 

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.

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.

Hard to believe this technology is 100+ years old. It’s a mechanical masterpiece.

The engineering, and machining to fine tolerances, back in wwi days. It's staggering. And beautiful.

The complexity, tolerances...design...all with paper and pencil...and lathe, handtools in the early days. Unsung heroes who made it all work.

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 RU-vid.

Stunning graphics - so clear and precise. Outstanding research and execution.

This is cleaver enough but think about the geniuses who designed the mechanism. Respect!

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 job! Please keep making videos like this, that would be awesome!👍

I'd like to see how the gun was conceptualized and the blueprints drawn back in the day of no computers.

Absolute perfect animation.

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.

Very well done. Impressive work.

Great job, thank you.

That is awesome! Thx

The fire control systems for firing the guns, were amazing.

Awesome video and explanation.

The same design and mechanism is used on Isostatic presses, We used to build them, Most were hydraulic operated and PLC controlled.

Another fabulous explanation.

Excellent 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.

awesome!

wow! most excellent! I hope you wil also do the us navy 16 inch rifle , the Bismarck and the Yamato. Then omg a video about the good and bads of all the rifles.

Absolutely excellent, a work of art each time.

Cool, a guide to building your own gun breech

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".

what intricate engineering!

RNbreech ... what a funny name :D impressive work by the way .... i am an engineer and can barely imagine how much work the research and CAD reconstruction took this video gave me a unique insight in this mechanism and i thank you a lot for this

Were the Bismarck, Iowa classes the same I wonder. Amazing war technology.

Riveting to watch!

The rendering style is unique.

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!

Very Great Job.Could you tell me how to get those blueprints.Thank you.

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 :)

It's really meticulous, how do you know so many details? Can you do a special issue on the breech block of the flak36 8.8cm artillery? very much looking forward to your show

Was these impressive images produced in Fusion 360 or SolidWorks perhaps? Great job that must have required many hours work.

When new this was the top secret of the UK.

amazing job! I'm curious where you can find good information on this mechanism and which cad software you used.

They should show how bismarck's gun barrel worked

What does the axial vent do?

Nice animation, must have been a lot of work

This is awesome quality! You should really add some audio to your videos though, nothing jarring just some light background music (maybe with a few audio cues to indicate the timing of events). Your channel deserves way more subs than you have right now.

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 ?

Great presentation. One comment though..............how is the shell actually fired ? Striker, hammer, shotgun shell ?

Try to design such a complex mechanism today without the assistance of a CAD software!

这是什么3d软件制作的呢？

I’ve never seen anybody explain how that breach block was made…

I thought that the French developed the interrupted thread design for big guns

4:00 "RETAING" should read "RETAINING"

This is close to being engineering porn 🤭

hi, put some music in the background, boring to watch

Rape oil, eh? Maybe proofread your carp before posting?
