After all, the drawings are only calculated, and in the case of not even doing the strength experiment of the material, they basically rely on the empirical parameters they have written down to design, and Xia Lin is also very drumming in his heart about whether his drawings can be converted into real objects.

This is also the reason why he wants to organize a research team to carry out a research plan.

Dividing the 40 senior employees of the research team into ten groups of 4, appointing each dwarf master as the team leader, directly under his own leadership, Xia Lin immediately began to act.

In the order of the easiest and then the hardest, the first is the problem of the gravity crusher, which consists of a closed table, a metal gravity hammer, a clutch device and a gear mechanism.

This is actually a simple forging machine, but such a clumsy equipment, in addition to the relatively large consumption of steel, is also relatively easy to manufacture.

Once the steel was in place, the finished product was quickly crafted by the dwarven masters, and the conclusion of the trial was that the efficiency was low, but acceptable.

The first breakthrough was successful, and this result inspired many team members.

Then there is the manufacturing of the conveyor belt, which has to lift hundreds of heavy materials ten meters high and put them into the feed port of the blast furnace without stopping every day, which has very high requirements for all aspects of the conveyor belt.

The best material for making conveyor belts is naturally rubber, Xia Lin found the bicycle research and development team led by Master Holguin in a corner of the machine factory, and found that Master Holguin was happily riding the bicycle they built by hand according to the drawings provided by Xia Lin in the open space outside the wide flat workshop.

"Yo, Xia Lin, your bike is really good, but it's useless in the wild! In the wild, it's better to have horned goats from our tribe, and those old fellows can take us to jump on them, no matter how rough the terrain is!"

Seeing Xia Lin and his party, Master Holguin happily rode the bicycle to their side, straddling the ground with his thick short legs, and patted the mount under his crotch with satisfaction and said to Xia Lin.

"Master Holguin, the main purpose of our bike was not originally designed and built for backcountry riding, it just needed to be able to drive on the road.

If there is a need, we can also make certain changes to the design of the bicycle, such as adding some shock absorbing equipment, widening the width of the tires, enhancing the stiffness and stability of the frame, so that it can be driven in the mountains and forests.

But even then, it's impossible to compare to the Horned Goat mounts of your dwarven tribe.

The tires of the bike you've got now are even wooden, which is a far cry from the horned goat. Master Holguin, haven't those raw rubbers yet been made into molded tires according to the process I provided you?"

Xia Lin said and carefully looked at the bicycle under Master Holguin's crotch, the basic frame is made of bolted hollow high-carbon steel steel tubes, the seat cushion is cowhide and natural sponge, the wheels, spokes and chains, and gear wheels are all handmade by dwarf masters, except that the seat height has been lowered a lot because it is a birthday gift for Hurley, and the shape looks no different from the old-fashioned bicycles produced in factories that Xia Lin has seen in his previous life.

….

Considering the skill level of the dwarven masters, the error of these delicate parts may be smaller than the 0.1 range that Xia Lin had previously requested.

However, one of the most critical components of the tire is the rubber tire that Xia Lin expected, and it is still a maple wheel that the dwarven masters have thought and made by themselves.

"How can it be so easy, we follow the process you said to bake those strange raw rubber and chop it, and then add carbon black, rosin, paraffin, kaolin, alkaline earth and other things to it, and then roll it with a rolling mill, but those tire pieces that we get after trying to roll more than a dozen times are easy to break, I'm afraid they won't meet your requirements."

Through the back door, they came to the machine shop, and in the corner of the back door, they had set up several small ovens, and a few newly built machines and equipment were placed aside, where more dwarves and employees were working on various tasks under the strange smell of glue.

"Look, these are the fetal tablets we've been making for a while!"

Master Holguin handed the bicycle to a dwarf, and then took out a chest from under the table beside him, in which various small compartments were separated by wooden boards, and in the numbered compartments were placed rolls of black leather-like objects.

Xia Lin touched these rubber tire pieces one by one, the unvulcanized rubber sheets still looked a little dry and hard at room temperature in early spring, frowned, and took out a few rubber sheets, Xia Lin used a little force, and the rubber sheets that should have been tough were slightly bent for a while and then broke, if there is only this quality, it is indeed not good to use it to make tires.

"Maybe there are too many compounding agents, you can consider slightly reducing the amount of carbon black, kaolin and magnesium oxide, forget it, just let me adjust the formula dosage for you!"

It's not a few days before Hurley's birthday, Xia Lin is not going to take that wooden-wheeled bicycle to the errand, that kind of wooden tires are fine to ride on flat roads, if you really want to go out to ride on the roads of the current imperial capital, I'm afraid that Hurley's butt with cushion cushioning and shock absorption will also be turned into four petals.

According to the recipe that Master Holguin had tried, Xia Lin reduced the amount of compounding agent by half and asked the workers to reopen the furnace to produce the rubber compound.

After adjusting the formula, the color of the rubber compound produced this time is obviously much lighter than before. After the cooling was completed, Xia Lin tried to break and stretch a few times, the toughness and elasticity were good, but the surface was quite sticky, and a slight drop on the table could leave clear black marks, obviously this quality could not meet Xia Lin's needs.

「…… Try again with this recipe!"

Xia Lin pondered for a while, and took a value from the rubber formula that Master Holguin tried last and the formula he had just made to continue the ingredient production.

Finally, after a day and a half of trying, Xia Lin got a compound compound formula with good strength, toughness and elasticity, and after calendering, this rubber compound became a layer of tire film two or three millimeters thick.

….

The roving mesh is padded between the film and the film as the skeleton of the tire, coated with the leather glue used by the tanners to bond and compact layer by layer, and the outermost film is printed with anti-skid lines through a printing machine, and finally the finished solid tire is obtained.

After a period of vulcanization, Xia Lin finally saw the first rubber tires in the world, accompanied by large strips of film, which were used to make conveyor belts.

"Is this the finished tire you want us to make?" It doesn't look like a big deal."

Master Holguin curiously stepped forward and pinched a solid tire that exuded a strong sulfur smell, pouting and saying, the dwarven master was obviously not as interested in metal and smelting as rubber was a strange thing that only alchemists would deal with.

"But with this tire, a bicycle is a bicycle!"

Xia Lin patted these vulcanized tires that were still exuding a slight heat with emotion, looked at the bicycle on the side, and immediately asked people to install two tires on the hub of the bicycle with great interest, and after adding these two gray-black tires, this bicycle finally fits perfectly with the bicycle image in Xia Lin's memory.

Although the bicycle was basically handmade by a group of high-level craftsmen, it was still a luxury handicraft in the strict sense of the word, not the industrial product that Xia Lin had in mind, but it was enough to make him happy.

Riding the bike around the open space at the back door of the machine shop a few times with great interest, Xia Lin experienced the feeling of getting back on the bike and nodded with satisfaction.

The shock absorption effect of solid tires is naturally not as good as the hollow pneumatic tires of the previous life, but it is still quite comfortable to ride on such a relatively flat ground, and this level is enough to take it out

Hurley is a birthday present, and when the roads in the imperial capital are almost repaired, Hurley can occasionally ride a bicycle to school and experience Xia Lin's student life in her previous life.

After instructing Master Holguin to use the remaining raw rubber raw materials to continue to try to make better quality rubber compounds, Xia Lin returned to the base of the research team with the rubber belts produced in the same batch to continue the manufacturing of conveyor belts.

According to his own design, Xia Lin uses a rubber belt as a conveyor belt, sticks leather strips on the front and back sides to enhance friction, and also sticks a wrought iron rod with leather strips as a roller, and adopts a screw tensioning device to ensure that the conveyor belt is not relaxed, and then assembles these parts with hydrodynamic rollers and brackets to obtain a formed conveyor belt.
