Chapter 69 Cannon System
Four days later in the backyard
Two deep holes were dug in the ground Each hole was in a circular shape, and the deeper it went, the narrower its radius becaround level, its diameter was around 40 cm but its deepest part expanded to only 26 cm These holes were the molds that Roland intended to use to produce his cannon prototypes The inner walls of the holes were baked and hardened by Anna She burned it so long that its surface ithout any flaws, just like a shell She began to harden the shell at the bottom and took all the air bubbles and scu history, there were several sizes of cannons; Roland roughly reht pound cannons got their naht of their shells Roland’s first step for producing a cannon was to produce several twelve-pound balls, and then calculate their sizes according to the diameter and the wall thickness of the cannon’s shell
In the absence of measurement tools, Roland simply created his own custom standard He took an iron rod and separated it into many s finger, hoping to come close to one centimeter After that, he created many copies of the iron rods
The diameter of a twelve-pound iron ball, when measured with the new iron ruler, was around twelve centimeters Because of this, the thinnest wall of the shell had to be four centimeters, and the rear end which was used as the detonation chamber would need to be seven centith, there were many different kinds of cannons, like the cannons used on battleshi+ps,artillery, so he really did not knohich to choose
Taking into account that the shorter the tube, the lighter the cannon would be and the more materials could be saved Roland dismissively waved his hand, I will just build a cannon with a length of 15 meters; if the tests results aren’t satisfactory, I will adjust the length later
When the cannon was originally invented, it was built with a wooden core and strengthened with iron rings, just like a barrel Roland still re and self-explosion, thus it would be better toout the cannon with a stea a 6-pound cannon or a 12-pound cannon
The so-called caliber was just a concept to differentiate between their sizes If thebeyond that couldn’t be used as field artillery But the exact weight of the shells or the cannon balls wasn’t iht line After all, he was only getting ideas fro it
Roland took a deep breath, then he gave Anna the signal to start “start now” The latter nodded her head, took a steel ingot, and placed it over the hole Under the power of her green fla a small waterfall out of lowed red-orange and becaht that it was hard to look at In order to protect Anna’s eyes, Roland specially set up a support fraood position first and then she could lean against the support fra into the hole
The ingots were normally only used up slowly After all, Anna alone couldn’t start the era of hot steel, but producing a s problem – the most difficult problem to solve was to hold the temperature at the same level, but with Anna’s help he was able to produce a small batch of excellent quality steel
This was also the reason why Roland dared to produce a cannon of the size of five meters Compared to the cannons produced out of bronze or iron, the cannon er Even if Roland built the cannon in the wrong size, the probability that it would self-explode was much smaller
The a torise within the hole, but the nu this, Roland couldn’t help himself but feel some heartache In the end, he only could wait until the time when he would beable to build some blast furnaces on his territory The nuots a noble could produce was one of the criteria used tothis time
When the two ht red because of her effort So, Roland took out his handkerchief and gently wiped the sweat fro care, Anna showed so, but after a few seconds she obediently closed her eyes and let Roland take care of her
Her face had a red shi+ne froRoland to think about taking a bite out of her However, when he looked further down her neck, her exposed, slender clavicle entered his view The both of theether that Roland could srance
“Ahem, well …” Roland e to control his restless e for today Well done! I will tell the kitchen to specially prepare a pepper steak for you”
