She Became A Downfall Noble Lady

Chapter 520: Chapter 518: Is It Still Difficult? Chapter 520: Chapter 518: Is It Still Difficult? Previously, when testing the Chain Inversion Device, most of the parts were made by woodworkers. Even the strongest wood is still wood, which is easier to carve and polish. Ironworking, however, is different. Although at that time ironworkers still valued their craftsmanship, able to create delicate items, mass-producing mechanical parts was not an easy task—it could not afford the time-consuming effort of several blacksmiths hammering away.

Fortunately, the parts are still in the prototype stage, where issues can be identified and remedied promptly.

Wong Qiao had arranged for the craftsmen to produce the parts of the Chain Inversion Device. Ye Xinyan gathered Wong Qiao, Zhou Biyao, and the official in charge sent by Jinrong to the workshop to discuss the tools needed for mass-producing ironware.

After some discussion, under Ye Xinyan’s intentional guidance, Wong Qiao and the two craftsmen sent by Jinrong, who had worked at the court’s Imperial Workshops Bureau, proposed several solutions.

Based on these solutions, Ye Xinyan roughly sketched out two commonly used mechanical tools—the bench vice—along with several mold designs for something like a hand-cranked grinding wheel.
