Oda Nobunaga probably had some swivel guns.

I've been researching Vietnamese firearms recently and the Le dynasty imported and designed their own breach loaders. The earliest cannons were likewise a mix of Portuguese, seized Dutch, and Chinese cannons.

Thats correct!

​@@JYFMuseums Great Work , how many hours does it take a Smith to make a Swivel Gun?

That's going to depend entirely on the smith, to be honest @@samparkerSAM

@guypierson5754 I always liked the Film from the 1970's showing the creation of a Long Rifle. I rebuild Civil War Musket and rifles down here in New Orleans

And probably dangerous

Like the swivel gun featured in the video, the earlist artillery to appear in Europe, generally known as bombards, were also forge built iron breech loading guns that fired stone shot. These early breech loaders suffered from gas loss at the point that the breech chamber and barrel's breech mated together. To prevent gas loss and maintain the increasing energy of the burning gunpowder, one of the first real technological advances in artillery was the transition from forged iron breech loaded guns to cast bronze muzzle loaded. And it will not be until the mid-19th century that artillery begins the return to breech loading, once a breech can be locked and gas loss prevented. Mind-boggling to know that artllery transitions from breech loaded, to muzzle loaded back to breech loaded.

Ian on forgotten weapons has shown a Wheelock rifle from I believe the 1600s that actually has a remarkably similar "cartridge" system. Very interesting as well.

I think this gun had modern tolerances in construction and back in the day a whole lot more flash would escape at the breech/ barrel. Still fantastic! I love cannons and still have never seen this rapid fire with pre loaded breeches. Great content

She also makes a stellar appearance in our video "Going to the Source | John Smith's Equipment List (Part 1)" and we are hoping to feature her in more content going forward.

This explains the speed issue. Women should never be gunners, as their reduced physical strength makes them ungainly with these tasks.

​@@mrfarts5176 Makes sense

​@mrfarts5176 Seemed like she did just fine to me. Get over yourself tool 😂

The missing are some approaching small boats of primitive inhabitants of distant lands.

Missing the load too, I don't think the rail could handle a loaded gun.

Most of it is only on films

With a load of shot considerably raising the chamber pressure you could expect a greater amount of gas blow by.

There is a similar method used in the earlier Dreyse needle gun

@@pauldavidson6321 Was going to post this. Probably some designs and units made had near perfect seal if wedged hard enough even with actual projectiles being fired, not that it really matters all that much for the terminal performance of the weapon, just consider how well recoilless rifles work and they are basically totally open at both ends, all that matters is that pressure being generated in the deflagration is mostly used to drive the projectile, average pressure is more important than peak anyways.

One of our staff just returned from a trip to England and a visit to the Mary Rose Museum in Portsmouth, where he had the opportunity to handle one of the stone shot recovered in the archaeology of the ship. What an amazing museum!

what replaced the forge welded seam in the 1800s, if you dont mind me asking?

They were still using 'forge welding' for the outside of huge cannons right up until the early 1900's - see Armstrong and Whitworth cannons. The shift started to come in when they developed better steel refineries and big steam hammers and hydraulic presses that could forge a single billet of steel into the liner - they started with a homogenous block of steel, drove a rod through the middle, then used shaped striking surfaces to draw the billet out into a long tube - every so often they had to drive a 'drift' through the center hole to help keep everything in the desired shape. Once it was long enough it would then be lathe turned to shape . Then the outer layers were shrunk on - the liner was cold and each reinforcing layer was heated well up towards yellow then forced over the previous layers until there were 2-3 layers of forge welded coils built up. That was then cooled, machined and the next layer forced on. Again, eventually metallurgy advanced enough that they could make and forge the huge billets in one piece, but up until quite late in the 1800's the outer layers were made from long strips of wrought iron (negligible carbon high iron silicate inclusion) coiled up around a former then forge welded into a cylinder before being machined and 'shrunk' onto the core. Guns were still in service through WW1 that were made with partly forge welded barrels. The change from black & brown/cocoa powder to nitro cellulose powder was another driving force in improved design - nitro powders could reach much higher sustained pressures so the barrels needed to be stronger much further from the breech, so gun founders developed wire wound barrels with layers of high tensile wire between the liner and the outer casing to make stronger and lighter barrels.

wait, what do you mean by pirates in 1970's?

@@karlez7664 What I mean is, Pirates ... being attacked at sea or at anchorage by a hostile vessel with criminal intent. The drug smuggling was in full swing back then and many parts of the Bahamas in the 70's were not safe.

@@karlez7664 fun fact, pirates are still a problem in 2023!

@@FishyBoi1337 On the US shores?

@@karlez7664 No, not in the US. The problem was in the Bahamas. It was and is a popular place for Yachting from the USA... in the 70's and 80's it was a popular place for drug smugglers too.

Having multiple breech cans preloaded is a game changer for speed, I never knew a swivel gun could be operated this way. In battle I expect another one or two gun crew members would be loading the cans in rotation.

Hey, thanks!

wrought iron is made by smelting iron ore with carbon monoxide gas, in that form it is pure iron, mixed up with the ashes of the fire. cast iron typically contains various other elements that alter its physical properties. the folding and hammering - fire welding in fact- drove out the ashes leaving puer iron in malleable form, a very fine material

Cast iron is generally infamous for having way more voids in it than forged things do. Even in WWII, rolled homogenous steel armor was preferred whenever practicable to cast armor (i.e. if the shape needed allowed it), because rolling (type of forging, basically) helped squeeze out voids, but casting would have those voids more often and be less reliable. hammering on an anvil does roughly the same thing, much more laboriously. A modern gun is probably usually made of rolled steel which is then machined in fancy ways for both the consistency and the shapes at the same time.

The last barrel welders are on movie from the 1920s on youtube

@@JYFMuseums If we ever meet, we can drown our mutual sorrows in some ale ( or sangria)

We cheat with ours ( a bit larger than this one) and slip an O ring in there as well (mostly for safety's sake to prevent powder burns). That completely eliminates any blow-by and is good for a dozen or so shots before needing replacing.

That's known as a "screw barrel". The system was used in everything from Turkish siege cannons firing huge stone balls to slender "pocket" pistols.

At this timeframe loggerhead was a slang term for a stubborn or hardheaded man. Neither John Smith in "A Sea Grammar" or Sir Henry Manwayring in "The Sea-Man's Dictionary" uses the term loggerhead to name or describe tools.

@@JYFMuseums I had come across the word before but Patrick O'Brian explained it in one of his books, which is how I heard the explanation of "at Loggerheads". I suspect from the name Loggerhead turtle that the shape was like the head of the turtle. Here is an explanation, that says nothing about using a loggerhead, of how drinks were heated in Taverns. kzfaq.info/get/bejne/jNh6driA15i5eWw.htmlsi=wHulqVx2-NbCn9sb loggerhead, n. An iron instrument with a long handle and a ball or bulb at the end used, when heated in the fire, for melting pitch and for heating liquids. This above from the Oxford dictionary
