At present, the main artillery of the Seawolf is mainly six-pounder guns and twelve-pounder guns, and the twelve-pounder guns are divided into three types: long howitzers and short guns, and there are also some Fran machine guns, these guns have no problem dealing with pirates along the coast of China, and they can even be said to be quite powerful, but if they are placed on Western warships, these guns are all light artillery and can only be used as secondary guns.

This is also the reason why Yu Xiaotian has now decided to phase out the six-pounder gun from the fleet, the main battle ships, this thing is indeed too powerful, if it is used against the European sail warships, it is basically similar to itching, and it is impossible to penetrate their hulls.

The twelve-pounder cannon was replaced with a twelve-pounder gun, which was much more powerful than the six-pounder gun, and the standard twelve-pounder howitzer and twelve-pounder cannon were the cannons, which made the firepower of the Seawolf's warship go up to a new level, but it was still a little powerless to deal with Western-style warships.

Therefore, Yu Xiaotian decided to equip the Sea Wolf with larger-caliber artillery to make it have stronger firepower, so as to ensure that it could easily sweep its counterparts along the Chinese coast, and at the same time, it should also be able to deal with the warships of the Europeans.

In the past, the Seawolf had a set of twenty-four-pound naval guns, but only two were produced and equipped on the chicken coop battery, because this kind of cannon was heavy, and the Seawolf had no ships to carry at that time, which belonged to the category of cannons, with a long range and strong power, but it consumed a lot of iron and weighed too much, so it could only be used as shore guns, and it was of little use to the Seawolf fleet.

Now he had to think about increasing the caliber and power of the guns, and at the same time controlling the weight of the guns so that they could be loaded on his current ships, so before that, he had to prepare to continue to strengthen the structure of his own ships so that they could carry larger and heavier guns.

Now, these new ships have been modified and continue to significantly strengthen their structure, allowing them to carry heavier guns.

After looking at the structure and construction of these ships, Yu Xiaotian expressed his satisfaction, these boats are carefully made by the shipwrights, the style is a bit like Western ships, but the construction technique is a common technique used by Chinese craftsmen, many problems he feels are difficult to solve, but after handing over to Guo Fu and other shipwrights, they can come up with a way to solve it, at this point Yu Xiaotian does not dare to underestimate the wisdom of these old shipwrights.

These shipwrights were basically illiterate, but they relied on the oral transmission of the previous generation, and they memorized many skills, and they also possessed considerable creativity, if it were not for the habitual conformism, these craftsmen could have built better ships than the Chinese sailing boats of this era.

On the amidship deck of one of the ships, Yu Xiaotian stood still, this is the back deck of the mast, which belongs to the widest place on the ship, where the ship generally opens as a hatch to enter and exit the ship, but the upper and lower hatches of this ship are adjusted to the front of the mast, leaving this space.

And here is also the strongest hull deck structure, the bearing capacity is also the strongest, the underneath is reinforced with beams and reinforcing ribs, enough to carry a lot of weight, including the thickness of the deck, has been doubled, so that this piece of land, a fairly solid platform has been obtained.

According to Yu Xiaotian's design, this platform is now equipped with a circular wooden outline, and a gun carriage is erected above the outline, and there are small wheels under the gun carriage on top of the outline, which can easily rotate the gun carriage and point the cannon on the gun carriage in any direction.

The gun carriage is a slipway gun carriage, which cancels the four small wheels under the gun carriage, so that when the gun fires, the recoil is directly transmitted to the gun carriage slide rail, which drives the gun carriage to move backwards to offset the recoil, and then the gunner can push the gun carriage back to the firing position after loading, so as to make the gun operation easier and faster.

However, there was still a problem, this contoured rotating gun carriage occupies a much larger area than the average wheeled gun carriage, which makes it impossible to place more guns on the deck of the ship.

However, for this kind of sloop, its carrying capacity is limited, and if it is equipped with large-caliber guns, there will not be many guns on the deck, and the impact is not very large.

However, at present, the contour of the ship's rotating gun carriage has not been completed, and the artillery is not in place, but the structure has been preliminarily completed, and the next step is to continue to adjust.

Yu Xiaotian paid attention to this thing, this was a way he had thought about for a long time, so that this kind of sloop could be loaded with a super-caliber cannon and obtain quite strong firepower.

After seeing this rotating gun carriage, Yu Xiaotian praised Guo Fu for their craftsmanship, he just drew a picture at the beginning, drew the structure of this gun carriage, and let Guo Fu and them try it, but they didn't expect Guo Fu to complete the design modification and manufacturing of this gun carriage so quickly, it can be seen that these craftsmen are indeed good, but they were too rigid in dogma before, which curbed their creativity.

"Yes, that's what I want, you're doing pretty well, it's basically the same as I thought, and it seems to be improving, not bad! Hehe! Yu Xiaotian patted the gun carriage that had not yet been equipped with a cannon and smiled with satisfaction.

Guo Fu hurriedly said: "After the big boss sent someone to send this picture over a few years ago, the small ones didn't dare to delay, so they quickly pondered it, first during the festival, they made a model on the shore, tried to modify it a few times, and felt that it should be possible, so they started to do it on the boat, but I don't know if it is in line with the meaning of the big boss, and now there is this sentence of the big boss, and the small ones are relieved!" ”

Yu Xiaotian nodded and said, "Satisfied, it should be very satisfied!" You're doing a pretty good job, so let's wait for the shots! Once the cannon is made, it can be shipped over and loaded onto the ship immediately!

That's it, I've seen it here, Guo Fu, you're doing quite well, it's better than I want to do, but now the shipbuilding speed is still a little slow, you keep an eye on it, increase the speed of shipbuilding, these three boats can be launched within five days, hang up the sails, and hand them over to the fleet to test the water!

As for the matter mentioned today, you can arrange it as soon as possible, and start doing it! This month, there is a batch of hard materials, which will be shipped from the Nanyang side, which can ensure that you will not be short of hard materials in the next six months, in short, I want a ship, you give me a way to build more ships quickly and well, I will naturally not treat you badly! ”

The artillery work in Tamsui City is also similar to the cannon work of Nanri Island, a hot scene, but compared to the cannon work of Nanri Island, the construction of the field here is more regular and larger than that of Nanri Island, unlike Nanri Island, the initial shed is relatively small, and the production was expanded in the later stage, and another shed had to be built, and the pattern was messy.

At the beginning of the construction, the artillery here was taken into account to expand the output in the future, and three large wooden truss structures were directly built, and the outside of the shed was the molten iron furnace, several molten iron furnaces were lined up, and the chimneys pointed straight to the clouds, spitting out billowing smoke.

The wood resources here are abundant, not as shabby as Nanri Island, the large timber used directly is used to build, the load-bearing column is directly driven into the ground very deep, making it appear very solid, at least the wind resistance is very strong, the wall of the field room has a large window of communication, which can be opened at ordinary times, the ventilation and lighting are quite good, the day makes the shed bright, once it encounters a strong wind or typhoon, you can close the window, and the shed can still continue to produce.

In the shed, there is a casting table, in the past, Nanri Island, mainly rely on manpower to carry the crucible to catch the molten iron, and then lift it to the casting table, the molten iron is poured into the mold cavity for casting, the manpower consumption is very large, and there is a certain danger, there was an accident, two apprentices who carried the molten iron accidentally fell, and the molten iron spilled, and the person who fell down was burned alive on the spot, and the other person was also splashed with molten iron on his legs, and was burned to cripplement, and almost lost his life.

So when Yu Xiaotian was building here, he let people make several manpower cranes out of hardwood, and installed a set of pulleys on them, although they still need to be operated by manpower, but they are relatively much safer, and they can also hold more molten iron at a time, so that the continuity of casting is stronger, so that the quality of the artillery produced will be a little better.

Making pulley sets, for Yu Xiaotian, is really not a problem, this thing has been in junior high school, basically can, as long as he comes up with a sketch, the craftsmen can naturally make it according to the sketch.

So in terms of scale, the scale of the cannon in Tamsui Village is much more than the scale of the cannon on Nanri Island, at least two or three times more, but at present, the output here can only be the same as that of Nanri Island, part of the production capacity has not been brought into play, part of the iron melting furnace and casting table have not yet been used, the key is that the number of craftsmen is insufficient, and the number of gun molds is not enough, so it can only reach the current level first, but with the apprentices and the number of workers increases, the output here will soon greatly exceed the output of Nanri Island.

When Yu Xiaotian arrived at the gunning, it was in production, among the three large sheds, there were individual casting tables that had not started, and the animal power blowers outside the sheds were pulled by oxen, making a whirring sound, and a large number of craftsmen in the sheds were busy working around some casting tables.

Some people are placing gun molds in the pouring pit, and then burying them with sand to make it a stable casting platform, while others are shouting trumpets, pushing human cranes, and hoisting large crucibles containing high-temperature molten iron, moving towards the casting platform, pouring red molten iron into the casting hole, sparks splashing, very lively.

There are also some people who are digging up the sand under the casting platform, digging out the cannon mold that has been cast and annealed, hoisting it out with a row crane, placing it on the ground, knocking the iron mold open, peeling off the pieces one by one, revealing the iron cannon that has been cast inside.
