Song Yang was also speechless. The power of the musket was so small.
Although there is no rifling, it shouldn't be that bad.
Returning to the wooden shelf, I carefully inspected the musket.
There should be air leakage at the end of the barrel caused by the gap being too large.
There should also be a little less propellant.
The gunpowder in the medicine room may also be low.
I put the projectile back into the barrel and observed carefully, I found that there was indeed a gap between the projectile and the barrel.
"My lord...it's all because of the small workmanship..."
Wang Jinshi didn't know what the problem was, but the power of the musket was obviously not up to Song Yang's requirements, so he was eager to admit his mistake.
Song Yang waved his hand to interrupt him, shook his head and said: "It's okay, there's no need to admit your mistake, no one is wrong."
"It's normal for the first try not to be successful."
"Relatively speaking, this thing is precision equipment. It is a miracle that it can be made perfect in one go."
While reloading, Song Yang explained to Wang Jinshi where he failed and where he needed to improve.
This time Song Yang wrapped the projectile with linen cloth.
In this way, the air-tightness performance is greatly improved.
The amount of gunpowder filled increased, and the gunpowder was compacted vigorously.
It was doubled in the medicine room.
When everything was ready, Song Yang pulled the rope and backed away.
The trained Renaissance soldiers no longer have any interest in muskets.
Everyone was waiting there listlessly for the experiment.
"boom!"
Song Yang pulled the rope, and the musket made a louder sound than the last time.
"Click~"
After the explosion, the musket fell directly.
Song Yang hurriedly went over to check.
"Oh my god...it exploded!"
Song Yang was speechless. It might be that there was too much gunpowder, the projectile was too tight, or the quality of the barrel was not good enough.
"This... actually opened the barrel of the gun!"
Wang Jinshi was a little shocked when he saw the chamber exploded.
He hammered out the barrel with hammer after hammer, so he was quite confident in its sturdiness.
"Old Wang, it's possible that the barrel of the gun is thin."
Song Yang pointed at the cross section of the cracked gun barrel and said.
"Your Majesty, I will make a thicker one when I get home." Wang Jinshi promised hurriedly.
"Uncle Wang, if you're afraid of this pipe cracking, how about putting another layer on the outside?"
Song Chengwang also came over to watch the musket test, and now he actually put forward his own opinions.
When Song Yang heard this, he thought for a while and said, "This method should be feasible!"
"Old Wang. In this way, you make each layer of the barrel slightly thinner, and then wrap it with two layers."
"Also, make another gun barrel with a thicker iron sheet."
"Let's try both methods. In the end, use whichever one works best."
The encyclopedia only provides an introduction to the functions of each component of the gun, but no clear manufacturing methods and dimensions.
Song Yang has to explore everything by himself.
Wang Jinshi wanted to thicken the barrel of the gun, but Song Chengwang said to use two layers of iron sheets.
Song Yang felt that what they both said was reasonable, so he asked Wang Jinshi to try two methods.
After that, Song Yang checked the records of several other parts that needed fine-tuning one by one, and today's gun test ended in failure.
Returning to the blacksmith workshop, Wang Jinshi immediately took the materials and started hammering.
Because this test failed, Wang Jinshi felt sorry for Song Yang's support.
Seeing him working so hard, Song Yang didn't say anything.
Just watch him work and see what needs to be improved.
"Clang clang clang!"
Wang Jinshi took two apprentices and started knocking.
Song Yang and Song Chengwang were watching from the side.
"Uncle Wang, blacksmithing is quite interesting. But it's just too hot..."
Song Chengwang's forehead was covered with sweat.
Although the smelting furnace was moved to an outdoor shed, the August weather and the baking in the smelting furnace made the temperature unbearable.
Song Yang was also hot, but he didn't feel as sweaty as Song Chengwang.
Look at Blacksmith Wang and his apprentices, they are also sweating profusely.
It seems that my body's resistance to cold and heat has also improved.
"Clang clang clang!"
The iron piece is knocked to a certain thickness and then placed on a groove.
When the hammer hits it, the iron piece begins to dent and bend.
After gradually making a ring, use an iron rod as a cushion to continue beating.
When the two sides of the iron sheets are joined together to form an iron pipe, the iron pipe is returned to the furnace.
Then sprinkle a layer of iron powder on the fitting gap as welding material.
After the whole body is red-hot, pick it out with an iron rod and continue to forge it.
Finally, the entire iron piece was bent and turned into a whole iron pipe.
After the iron pipe is tempered, the shape of the pipe is corrected, and finally it is buried in insulation sand and annealed.
This was Song Yang's first time seeing the whole process of blacksmithing, and he didn't understand the meaning of tempering and annealing.
After looking through the encyclopedia, I realized that this is to increase the toughness of steel and reduce its hardness.
Blacksmith Wang just studied the barrel of the exploded gun for a while and felt that the hardness of the barrel was too high, so he took the annealing step.
After the barrel began to anneal, Blacksmith Wang brought another iron ingot and started making the second barrel.
The one just now was made of thickened iron.
This one is made of thin iron sheet and double-layered barrel.
"Clang clang clang!"
The operation is as fierce as a tiger, and the bending of the thin iron sheet is much easier than that of the rear iron sheet.
Although the beating wasted some time, the bend was completely recovered beforehand.
The two layers of iron sheets came down a little faster than thickening the barrel.
After the two barrels were annealed, they were taken to the hydraulic workshop together.
Fix the barrel in the wooden groove and install the drill bit.
As soon as the wedge of the water wheel drive shaft was inserted, the drill bit began to violently advance into the barrel...
"Your Majesty, I am confident that there will be no problem with the barrel this time."
Wang Jinshi looked at the gun barrel being polished and said.
By building the barrel this time, Wang Jinshi summarized some previous mistakes and omissions.
After some process adjustments, Wang Jinshi felt that there must be no problem with the barrel this time.
And he felt that whether it was thickened or double-layered, it would be much better than the previous test product.
"Yeah. I believe you too."
"Don't worry, let's not be in a hurry, just try slowly." Song Yang comforted.
Even if he still failed this time, Song Yang wouldn't say anything more.
When developing new things, failure is the mother of success.
It takes at least five or six days to drill the barrel, and it also needs to be trimmed by hand afterwards.
In addition, this time Song Yang also planned to have Wang Jinshi carve rifling.
Tell Wang Jinshi about rifling.
Wang Jinshi thought for a while and said: "Hydraulic drills should not be difficult to carve rifling."
"If you do it manually, it will probably take more than half a month."
Regarding time matters, Song Yang is not very tight.
Just tell Wang Jinshi to do it slowly and not to rush.
When we left the hydraulic workshop, it was already dusk and sunset.
On the way to the dining hall, Song Chengwang suddenly asked:
"Uncle Wang, do you think if the gunpowder is put in a larger iron pipe, can it launch larger projectiles?"
Song Yang looked at him and shook his head: "Don't think about this problem first. Although it can be launched, we currently have no materials to make artillery."
"Artillery? The small ones are called muskets? The big ones are called artillery?"
Song Chengwang immediately understood the key points of Song Yang's words.
"Then Uncle Wang, don't forget to ask me to come and watch when we are making the artillery."
Song Chengwang said enthusiastically.
Song Yang looked blank at this kid and said angrily:
"You still need me to call you? Which of these experiments have I called you?"
