Joseph patiently explained to the old man:
"You see, the power of the water-powered forging machine comes from the water flow, and the speed and strength of the water flow are always changing, causing the output power of the forging machine to fluctuate, which seriously affects precision.
"Due to the unpredictability of the water flow, overly precise gear and crankshaft structures cannot be used as they can be damaged by a big surge.
"However, the steam engine can always provide a steady output, allowing each blow's distance and force to be accurately controlled.
"Moreover, by finely controlling the steam volume with very precise valves, the hammering force can be delicately adjusted. Releasing the steam stops the forging immediately."
Joseph glanced at the old man, who was already lost in reverie, and continued, "Ten tons is the limit for water-powered forging machines, but for steam forging machines, it's just the beginning.
