Many leather craftsmen may not have thought that they would make a name for themselves. They are comparable to the rewards of senior craftsmen, and their monthly income is at least several hundred trump cards.

If merchants are willing to invest in the leather industry, they have a market. Cotton spinning companies and breeding companies that have purchased hundreds of sets of equipment mainly engage in shoe making.

With sewing equipment, the speed of making leather shoes is accelerated, and the finished soles produced with rubber processing work can be increased by at least three times.

This is based on the fact that you are just starting to use sewing equipment, and after a period of proficiency, the production efficiency may be improved.

The news in the leather workshop in Youzhou is still very influential. Businessmen have already searched for craftsmen to make leather goods everywhere.

The salary offered was very high, so the city guard's mansion specially checked the newspaper to spread the news, in order to attract talents to Youzhou.

When the people of Ningzhou, northern Liao received the news, they immediately sent representatives to Youzhou to order equipment. Ningzhou is a big city for leather shoes processing, and at least 60% of leather goods processing are completed in Ningzhou.

After not knowing that the company was spread by Youzhou, the city guards of various cities and counties sent representatives to Youzhou for business trips to understand the situation. They all wanted to make some achievements for local development.

Many businessmen also came here just to understand the situation in depth.

Even businessmen who were not involved in the leather industry came to join in the fun, and the staff of the city guards in various places were very supportive of this.

It is a good thing to pay attention to communication at all times in business trade, so when the Youzhou City Shoufu attached great importance to it after the meaning of communication, Youzhou held another commercial exchange meeting.

The time will be settled in two months, and the merchants will provide communication platforms and will also conduct technical exhibitions.

The development of the city county cannot rely solely on the city guard's mansion. The investment of the city guard's mansion can only play a leading role. If you want to develop, it depends on the merchants and the people.

Therefore, it is necessary to publicly promote some technologies so that the people can know the importance of knowledge.

The Houcheng Shoufu, a native of Ningzhou, sent Tong Fu to receive it himself. Li De also attached great importance to Ningzhou's representatives. He proposed to develop the farms and leather processing plants in Ningzhou at the beginning.

He must pay attention to workshops that occupy at least 60% of the market, and he does not want chaos in the industry.

The key is that Ningzhou's leather workshops are very powerful, so how can we not pay attention to them as a local pillar industry?

They wanted to purchase a thousand sets of hand-crank sewing machines. Li De's suggestion was that they could purchase a batch of internal combustion engines to provide good power, but production equipment that needed modifications might be much more complicated.

However, if you invest, the advantage is that you can sew and make it faster, and the disadvantage is that you may need to change the entire processing workshop room.

The idea of ​​an internal combustion engine driving hundreds of sewing equipment is to use multiple bearing gears and iron pipe long gears to connect them to the sewing equipment.

When the internal combustion engine is working, it can drive each extended gear rod to provide kinetic energy. As for the transformation cost, it will definitely be a lot. Whether it can be realized in technology is still uncertain. This requires discussion with the craftsmen.

However, Li De would not really interfere with the other party's choice. If it is customized hand-crank sewing equipment, it will only take half a month to produce one thousand hand-crank sewing equipment.

Ningzhou representatives were not in a hurry after hearing this, and they were more inclined to develop small internal combustion engines to drive single-body sewing equipment.

As for the strange ideas given by Li De, they were surprised, but in fact they didn't understand them at all.

But this does not mean that Li De has lost his prestige. After all, he also said it in advance that it was a suggestion for technical matters.

When Li De proposed his idea, the craftsmen thought it was feasible, but the methods of use were different. The power provided by the internal combustion engine was mainly connected flywheels. As long as the number of flywheels was increased on this basis and the gears connecting the flywheel provided power to multiple equipment, the conditions could still be met.

The only disadvantage is that it takes up some space and the number of connections may be reduced to twenty.

This is also for the stability of power provided by the internal combustion engine.

After cost calculation, the cost is much higher than the cost of a hand-crank sewing machine. According to the cost, it is better to directly purchase a thousand hand-crank sewing machines.

Li De felt that not all equipment needed to provide things with internal combustion engines. After all, he might be more anxious when he thought about it to quickly improve production, so he decided to let the craftsmen develop foot-type sewing equipment.

Using rubber belts to drive the flywheel to provide power is the type of sewing machines in later generations, but this kind of power is still not enough to make leather goods.

But it does not prevent him from giving suggestions, and these can only be achieved after further development of new sewing machines.

However, the suggestions given by Li De were enough to make the craftsmen work hard. In the end, the representatives of Ningzhou directly customized a thousand hand-crank sewing machines and also applied for ten heavy-duty cars from Chengshoufu.

The car workshop has never given up production, and it is a matter of time to popularize cars to various cities and counties. Ten heavy cars were directly approved and then returned this time and could carry a large amount of goods back.

Not running empty cars is the best way to save car costs and make the best use of everything.

The craftsmen's efforts were all about seeing whether the craftsmen in the blacksmith workshop were lucky or not, and after many experiments, they really developed steel.

After testing, the craftsmen are very enthusiastic about their work.

All the weapons and armors before the new steel will become past styles after it was produced, and Li Deke does not allow steel to be used to make these things.

Craftsmen can only choose to use new steel to make internal combustion engines. With stronger materials processing, it is no problem.

The following work all began to devote themselves to the technical breakthroughs in the production of materials on internal combustion engines, which also changed the technical upgrade of the firearm workshop.

A large number of firearms made in the firearm workshop began to be replaced by steel.

During the development of iron smelting technology, but welding technology has also been developed. For example, old-fashioned welding has become the mainstream welding method.

In addition to the embryos formed in one-time, the internal combustion engines need to be connected by bolts.

Another project under development in the Blacksmith Workshop is about welding air gun production. If you want to provide welding requirements, you need to heat up at the connection.

According to the current firing and heating, only some simple iron products can be heated in old-fashioned ways, and there is no random welding level.

Therefore, the project team is developing a method of using sealing boxes to introduce the furnace into the ignition tube for centralized heating to facilitate welding.

However, due to restrictions on materials and other aspects, the research and development of kerosene welding guns has not been successful so far.
