Reborn In 17th century India with Black Technology

217  Machine Tools Part : 2 (Hardcore, Technical Stuff)

Dakshin Bhartiya Empire, Vijayanagara state, Raya Machinery Company.

After a short celebration following the successful manufacturing of the turning machine, Vijay ordered the craftsmen to get back to work right away.

This time, it was a large machine, as it was decided that the rest of the machines would be powered by water wheels. Vijay also decided to establish special industrial areas along the banks of the major rivers in the empire. He had already sent people to scout out suitable locations for the establishment of such industrial zones.

Out of the numerous rivers in Southern India, Vijay singled out the six largest and most crucial ones: Godavari, Kaveri, Tapi, Mahanadi, Krishna, and Narmada. These rivers served as lifelines for the people of South India. While Vijay couldn't help but feel concerned about the potential environmental impact of industrial waste being disposed of in these rivers, he acknowledged the current reality. However, he resolved that when steam-powered machines were invented, he would never allow the water sources of the Empire to be contaminated, at least not to the extent that the British did with the Thames River, which turned into a sewer because of the waste generated by the world's most industrialized country releasing their waste into the water.

The next machine Vijay is leading to manufacture is a drill press, a crucial tool for the industrial progress of the Empire. It plays a vital role in machining, especially in tasks such as hole creation, countersinking, and counterboring. Therefore, it is evident that the hydraulic drill press is a pivotal machine to include in the Empire's industrial upgrade plan.

With the help of Hey Ram and his team, Vijay initiated the process of building a water-powered drill press. Similar to the turning machine, they began by constructing a sturdy wooden frame to house the mechanism. Hey Ram, along with the craftsmen, assembled a waterwheel shaft to a crank mechanism using gears and pulleys designed by Naveen Bhatt. Following this, Vijay instructed the blacksmiths to forge vertical spindles from iron and create a quill mechanism to move the drill bit up and down. A sturdy table was crafted to securely hold the workpiece. As a finishing touch, a chuck mechanism from iron was forged to hold drill bits of various sizes.

Next, it was time for testing.

Power Source: Waterwheel

Drilling Capacity: Up to 1-2 inches diameter holes (depending on wood/metal type). Suitable for drilling holes for joinery in furniture making and creating holes for rivets in metalwork.

Speed Range: Limited speed range, potentially adjustable through gear ratios on the waterwheel. Offers faster drilling compared to hand-powered options.

Material Compatibility: Wood, soft metals (iron, brass).

Main Advantages: Increased drilling speed and efficiency compared to hand-powered options.

Limitations: Requires access to flowing water, and limited control over drilling depth and precision compared to traditional drill presses.

After the hydraulic drill press was manufactured, it was time to produce the milling machine. A milling machine could be used to flatten rough surfaces of metal parts for forging or casting. It can also be used to create simple grooves or slots in metal parts for functional or decorative purposes and to square off the end of a metal bar or workplace. Although the milling machine Vijay designed was far from the functionality it had in the 18th to 19th century, it was already a few decades ahead of its time in the current era.

To construct this, a frame made of robust wood was used to handle the forces involved. Naveen connected a waterwheel shaft to a gear system that drives a rotating mandrel. Hey Ram forged a simple milling head from iron to hold the cutting tool. Vijay ordered the artisans to create a work table that could be adjusted for different workpiece heights and angles. Although the adjustments were limited, the design was still functional. Finally, a basic mechanism was developed to move the workpiece against the rotating cutter for shaping. With that, the manufacture of a hydraulic milling machine was complete.

As for its results after the test:

Power Source: Waterwheel

Workpiece Capacity: Relatively small due to the early stage of development (estimated 6-12 inches). Tasks include flattening the surfaces of metal parts and creating simple grooves or slots.

Cutting Tool: Single or limited selection of rotary cutting tools

Material Compatibility: Primarily soft metals (iron, brass)

Main Advantages: First step towards more versatile milling technology, faster shaping of metal compared to hand tools

Limitations: Very rare in the early 1650s, limited functionality and control compared to traditional milling machines

The next machine to manufacture is the hydraulic grinding machine. The grinding machine plays a crucial role in providing various aids to the tools used by the industry. A grinding machine could be used to sharpen tools and blades made of metals such as chisels, axes, saws, or swords. It can also be used to remove small raised edges or imperfections left behind from the metalworking process and to smooth and finish the surface of metal parts from forging or casting.

Similar to the previous machines, a sturdy wooden frame is built to support the grinding wheel and shaft. Naveen Bhatt connected the waterwheel shaft to a gear system to drive a horizontal shaft, and a large natural grindstone, such as sandstone, which was mounted on the horizontal shaft. A trough was created to hold water used for cooling the grinding wheel and workpiece. As a finishing touch, a simple work rest was manufactured to support the workpiece during grinding.

After the manufacturing of the machine, it was tested:

Power Source: Waterwheel

Grinding Wheel Size: Up to 12-18 inches diameter

Tasks: Sharpening tools and blades, grinding and finishing metal surfaces

Speed Range: Limited speed range, potentially adjustable through gear ratios on the waterwheel. Faster grinding compared to hand-powered options

Material Compatibility: Primarily metal tools and blades

Main Advantages: Increased grinding speed and efficiency compared to hand-powered options

Limitations: Requires access to flowing water, limited control over shaping and finishing compared to traditional grinding machines

The next machine which was up for production was the hydraulic screw press. Previously, manufacturing screws on a large scale was a challenge due to the intricate craftsmanship required for each screw. However, with the introduction of the turning machine, slight modifications can transform it into a screw-cutting lathe machine specialized for producing screws. Much like the screw-cutting lathe machine, these newly manufactured machines can supply parts to each other and work in tandem. Vijay wholeheartedly believed that with technological advancements, the Dakshin Bhartiya Empire would be well-prepared to harness the advantages of the Industrial Revolution.

As for the uses of the hydraulic screw press, it could be utilized in various applications. The hydraulic screw press could bend thick sheet metal into desired shapes for applications such as creating brackets, housings, or decorative elements. Moreover, it could shape hot metal by applying pressure to deform it into desired shapes. In the manufacturing industry, the screw press plays a vital role, as it can press metal components together or other fasteners used in metalwork. While only Vijay knew all the deeper uses of these machines, the scientists working on them considered them to be a faster way to accomplish their existing tasks. However, Vijay was confident that with his knowledge imparting, these ideas would automatically come to them.

As the deadline approached, construction began with the frame being built of a sturdy wooden structure to withstand the immense pressure produced by the screw press. Hey Ram forged a large screw thread from wrought iron to create a strong nut to fit the screw. It was Vijay who came up with this design. Next, Naveen Bhatt connected the waterwheel shaft to a gear system that he designed to drive a large gear attached to the screw. Following Vijay's order, a flat square platen manufactured from iron was forged to apply pressure to the workpiece. As the last step, a thick and sturdy base plate made from stone was used to support the press.

It was time for testing:

Power Source: Waterwheel

Force Capacity: Up to 2 tons (estimated)

Bending thick sheet metal, shaping metal parts through forging, assembling metal components with rivets

Operating Speed: Slow due to reliance on waterwheel rotation

Increased pressing force compared to hand-operated screw presses

Material Compatibility: Primarily metals (iron, brass, copper)

Main Advantages: Significantly increased pressing force for metalworking tasks

Limitations: Requires access to flowing water, slow operation, potential safety hazards due to large forces involved

The last machine to be manufactured, which Vijay invented at the last moment, was the hydraulic rifling machine. The sole purpose of this machine is to produce riflings for guns and cannons. Manual rifling is a labour and resource-intensive task, which even the Dakshin Bharatiya Empire could not afford.

To build a hydraulic rifling machine, a robust frame was constructed to handle the precise operation of the machine. Navieen Bhatt connected the waterwheel shaft to a gear system that drives a rotating mandrel. Hey Ram forged a specialized rifling head from iron to hold the cutting tool. This head would move along the barrel length, guided by a track, thereby rifling the gun. A mechanism was then created to securely clamp the gun barrel in place during rifling, and a specialized cutting tool was forged that could create the desired rifling profile within the barrel.

This was the easiest machine to manufacture as it had only one function, and that was to produce spiral grooves inside a metal pipe.

Vijay brought over a Muscat in order to do the testing:

Power Source: Waterwheel

Workpiece Capacity: Primarily for gun barrels (estimated 0.5-1 inch diameter)

Creating rifling grooves inside gun barrels for improved bullet stability

Cutting Tool: Specialized cutting tool attached to a rotating mandrel

Material Compatibility: Primarily gun barrels made of soft metals (iron, steel)

Main Advantages: Increased speed and consistency in rifling gun barrels compared to hand-powered methods

*Thud.*

Hey Ram fell down as he crumbled to the ground. Naveen was no different, as he decided to rip open his safety coat and prowl over the ground in exhaustion.

The craftsmen who were employed to help were no different as they collapsed on the ground with exhaustion.

As Vijay observed the scene, with craftsmen in safety coats scattered on the ground like tired pigs, a wave of nostalgia washed over him, reminiscent of his past life. He couldn't help but recall the days when he and his fellow researchers, much like the current situation, laboured tirelessly day and night to perfect the thrust vectoring in the imported Pratt & Whitney engine booster. Those were indeed fond memories, filled with camaraderie and the excitement of innovation.

* Clap! *

* Clap! *

"Everyone, well done! You have outdone yourselves. It would be impossible to finish the task on schedule without your skilled experience, So Expect a great reward from the royal family," Vijay said as the people sprawling over the ground, with great difficulty, got up to their feet and bowed down to Vijay.

"This is what we should do, Your Majesty. We are very honoured to be of use to Your Grace," an older craftsman said with humility, to which all the other craftsmen nodded their heads, including Hey Ram and Naveen.

"No need to be humble. This is what you all deserve. The reward is not only for the work you have done but also for maintaining the secrecy. You are all craftsmen and scholars from either the Bharatiya Academy of Sciences or the Bharatiya Academy of Military Sciences. Hence, I hope you all understand the consequences if this news is leaked."

Listening to the stern warning given by Vijay, everyone was momentarily panicked. But since they were already part of the Bharatiya Academy of Sciences and Military Sciences, they knew what they were prepared for since the day they signed up. Hence, they all collectively nodded their heads and made a gesture of shutting their mouths, signifying that they were willing to keep the secret.

Vijay, looking at the promises made by the craftsmen, was also relieved. Maybe the best option would be to kill all these craftsmen now. Although he was not averse to doing such a thing, he felt that it was too much of an overreaction if he did end up doing it, especially since Hey Ram and Naveen both were involved in the project. They were two of the best scientists Dakshin Bhartiya Empire had to offer, hence Vijay would never do an action like shooting oneself in the foot. Finally making his mind clear, Vijay said, "Alright then, I will not keep you any longer. The royal family has arranged a banquet for all of you tonight. Spend the night with peace of mind. You will be free to return to your homes tomorrow morning along with your rewards."

Listening to Vijay's arrangements, the craftsmen in the crowd cheered loudly as they were no longer reserved. They would very much love to taste the food made by the chefs in Bukha Youdha Street, the empire's most famous food street.

"Yes, yes, yes!"

"Thank you, Your Majesty!"

"Thank you!"

"God! I can't wait."

P.S. It's that time of the semester when you have to finish all the records within a few days, I finished a few pens already, and I fking Hate this.

P.S. Also each Experiment is 6-9 pages full of useless SQL code.
