As for things like shovels and pickaxes, it's not a problem, the sea wolf is now concentrating on the limited blacksmiths in the shipyard and the cannon and the gun, and the production of firearms and ships, like this ordinary tool, the sea wolf has stopped producing for a long time, but these things are indispensable, so in the form of orders, they are customized in some iron yards or blacksmith shops on land, and then directly transported back to the sea wolf's territory for delivery.

Even now, even the cold weapons, knives, axes, spears, hooks and guns used by the sea wolves are secretly ordered on land, and then transported back to equip the sea wolf tribes.

In doing so, the limited blacksmiths were basically freed from the work of crafting simple tools and devoted to more important work, so that the production of guns and cannons of the sea wolves continued to increase, and greatly improved the equipment level and combat effectiveness of the sea wolf people.

Moreover, this kind of work is handed over to the ironworks and blacksmiths on land, which also allows the sea wolf to establish business ties with many places on the land, reducing manpower consumption and not affecting the normal use of the sea wolf.

However, there are some troubles with the problem of vehicles that are indispensable in road construction projects, and the Seawolf now has a carpenter, in addition to construction, furniture and weapons, it can also produce some vehicles, and even include some gun carriages, and the Seawolf can also produce its own.

But at present, the vehicles made by carpenters are mostly some clumsy and heavy two-wheeled ox carts, which are strong enough, but they are heavy, and the road requirements are also higher.

However, these ox carts need animal power to pull them, and they inevitably occupy ploughing cattle, and if they use manpower, it is very laborious, and it is not possible to enter the construction site during construction.

Therefore, if you want to carry out road repair projects, it is indispensable to use some light manpower vehicles, which must be easily pushed by manpower, and the carrying capacity can not be too small, and must be able to walk a very narrow road, and the road requirements must be low.

After thinking about it, Yu Xiaotian only thought of the wheelbarrow, so he asked the carpenter's workshop to try out a few wheelbarrows.

The carpenter's workshop was not ambiguous, and immediately started to make a few wheelbarrows and sent them to Yu Xiaotian for Yu Xiaotian to inspect.

After Yu Xiaotian saw these wheelbarrows, he was quite disappointed, because there are not many unicycles in the south, and the unicycle styles made by these craftsmen do not meet his requirements, and when these unicycles are actually used, they still look very clumsy, the center of gravity is not easy to grasp, the balance is not very good, it is more laborious to push, and the user will soon be tired enough.

Even if most of the users are slaves and slaves, but in such a project, Yu Xiaotian still feels that he can provide some convenient tools for them to use, which is not sympathy for those slaves and slaves, but can effectively improve efficiency and repair the road as soon as possible.

So Yu Xiaotian had no choice but to go into battle in person, with the help of a kind of chicken bus that was more commonly used in the countryside before the seventies in memory of the countryside, he drew a few structural drawings of the wheelbarrow, and adjusted the center of gravity as much as possible, so that after the wheelbarrow was loaded with goods, it was easier to be controlled by the user, and at the same time, it consumed less energy, and this chicken bus itself is also a kind of wheelbarrow, which is easy to manufacture and is more suitable for use on rugged roads.

Originally, bearings in this era have not been invented, like this kind of wheelbarrow, axles are reluctant to use iron to do, are made of hard iron pear wood, or made of lychee wood, relying on a little oil to lubricate, the friction itself is very large, it is very laborious to push, if the center of gravity is not well controlled, not to mention the effort to push, it is easy to overturn.

So the carpentry workshop according to Yu Xiaotian to draw a few patterns, and rushed to make a few wheelbarrows out, this time basically reached Yu Xiaotian's satisfaction, although this thing is a little simpler, but it is still lighter than the previous batch of wheelbarrows, but also easy to control, and after the test, this kind of wheelbarrow according to the deformation of the chicken car, can carry 200 to 300 catties of goods at a time, by a person can be pushed, basically met Yu Xiaotian's requirements.

Listening to the squeaky friction sound made when the wheelbarrow was pushed, Yu Xiaotian felt that it would be great if he could make a bearing now!

Not to mention these civilian vehicles, after using bearings, it will become much lighter and faster, if used on the gun car, the gun car will become more convenient, and the movement will be much faster.

Originally, the sea wolf lacked animal power, and the Ming Dynasty used to introduce some Mongolian horses to meet military needs when the Eastern Tatars were not in turmoil, but now Liaodong has been occupied by Jiannu, and the Mongols have been subdued by Jiannu, which has made Daming lose an important horse supply area, and now Daming's horses have become very expensive, and most of them are used in the army.

The south has a dense water network, which is not suitable for cavalry sports, and because of the climate, even the military is rarely equipped with horses, and the rich are not willing to serve such animals, making it difficult to find suitable horses in the south, and even if they are sold, the price is ridiculously high.

Therefore, the sea wolf has always been very short of horses, and can only use cattle as the animal power to pull the vehicle, but the artillery of the war battalion is obviously not suitable for using cattle as the animal power to pull the cannon.

Therefore, the artillery of the sea wolf can only use manpower instead of horses to pull the artillery.

Even if Yu Xiaotian now led the carpenters and blacksmiths to make a gun carriage that was much lighter than the gun carriage currently used in the Ming Dynasty on land, and greatly reduced the weight of the cannon, but such a gun carriage still looked heavy and clumsy when used.

Even if they are currently equipped with this kind of light twelve-pounder mountain howitzer for the use of the barracks, the weight is not large, every time they march in the field, each gun must be equipped with thirty gunners to tow these cannons, just like that, it is not possible to let the gun carriage keep up with the team, a little farther down, the artillerymen are tired of the fart, and once the battle, this kind of cannon still belongs to the erection of the artillery, pushing the cannon is also heavy physical work, and the artillery can be said to be very, very hard.

Therefore, the bearing is also a very urgent need for Xiaotian, once the bearing is manufactured, then the friction between the wheel and the axle when the gun carriage is moving, so that the gun car can reduce a lot of manpower consumption when it is moving, save the physical strength of the artillery, and make it possible to have physical strength to put into the battle.

There is no way to use people to replace animal-powered war horses, you must know that in the Napoleonic era, an artillery company was only a war horse that pulled a cannon, there were one hundred and ten horses, such a number of war horses, now Yu Xiaotian can't think of it, even if all the horses on the territory he currently controls are concentrated, I'm afraid there are not thirty or forty horses, and even one artillery platoon is not enough horses.

Looking at the wheelbarrow, Yu Xiaotian took out his notebook and recorded the bearing, but if you want to produce bearings, you must at least solve the problem of bearing steel, and the steel used in the bearing, at worst, must use high-carbon steel, and it must be quenched.

Thinking of this, Yu Xiaotian couldn't help but sigh again, when will he be able to produce steel by himself! It seems that this steelmaking problem must be solved as soon as possible, and only by solving this problem can we break through the various bottlenecks formed by all parties at present and make new breakthroughs in its industrial development.

As for the too high-grade steelmaking furnace, he will definitely not be able to get it now, so even if it is a blast furnace on the soil, the pollution is a little bigger, the waste is a little bigger, and the product quality is a little worse, it is acceptable, it is a big deal to step by step, and after the industry has developed to a certain extent, it is not too late to upgrade the technology.

I thought that after the chicken bus variant unicycle came out, the problem would be solved, but the carpentry workshop gave Yu Xiaotian feedback back a not very good news.

Making this kind of chicken cart is not too difficult for a carpentry workshop, and the frame can be made by even the clumsiest rough carpenter, and it is guaranteed that one or two hundred cars will be made quickly.

But in the production of wheels, but encountered a problem, this era of making wheels, is a special craft, not all carpenters can do, to make the wheel is durable, and the roundness is good, must have a special wheel craftsman to do.

The wheels of this era are basically made of wood, and there are very few wheels made of iron, at most some wrought iron sheets and iron nails are used to reinforce the wheels, but the main material is still made of wood, and the requirements for wood are relatively high.

If you ask an ordinary carpenter to make the wheels, the wheels will not be durable, the load-bearing capacity will be poor, and the axles will be easy to break.

So to do this, you have to use a craftsman who specializes in making wheels, but the problem is here, Seawolf does not have enough craftsmen who make wheels, and among the carpentry workshops, there are two who can make wheels on Nanri Island, and there is only one who can make wheels on the side of Tamsui City, including the chicken coop, and there is only one craftsman who specializes in making wheels.

These craftsmen who make wheels are usually not too busy, mainly to make some wheels for gun carriages, and the wheels used for the gun carriages of naval guns are all small wheels, which is easier to do, but the wheels of gun trucks used by soldiers and vehicles used to transport goods must be large wheels, which is more troublesome, and must be made strong, with strong load-bearing capacity and good roundness.
