The removal of the short bearing sleeves required six hours of manual labor in the dark of the wheel-pit, the water from the tail-race shut off until the current trickled through the lower timbers like bleeding sap. Wat's apprentices worked with short iron wedges and heavy beech mallets, their breath rising in thick, grey plumes that hung beneath the wet joists. When the old lead pieces were finally pried loose from the oak sills, they were misshapen, their circular bores compressed into shallow ovals by the relentless downward thrust of the spinning manganese axle.
Thomas stood in the center of the courtyard, his boots caked with the white crust of slaked lime from the masonry trench. A low wooden bench had been set up near the crucible furnace, where Wat had arranged the new, extended sand-molds. These templates were twice the length of the original seats, built using a pair of three-inch iron gate-valves as a structural core to ensure the internal curvature remained perfectly uniform during the pour.
He pulled the device from his tunic, checking the status of the local text files.

He verified the pouring parameters he had extracted from the metallurgical cache during his previous night's watch. The guidelines were rigid regarding pure lead matrices under continuous heavy friction; without antimony to bind the crystals, the internal surface speed of the spindle could easily liquefy the seat if the lubrication layers failed for even five minutes. The text insisted on a deep, continuous spiral groove rather than straight channels, forcing the oil to travel the entire length of the bearing before escaping into the river-well.
"The lead is ready to run, Thomas," Wat said, stepping up to the bench with a massive iron ladle clutched in his thick, leather-gloved hands. The liquid metal inside the bowl was a heavy, shimmering mirror of molten silver, its surface skin changing from gold to deep purple as the cool morning air hit the rim. "We used the old roof-gutters from the chapel line to make up the weight. It's clean stuff, but it handles soft under the scraper."
"Pour it slow, Wat," Thomas said, his hand resting on the wooden rim of the sand-box. "If you drop it in too fast, the air will pocket in the bottom of the die, and we'll have a void that will crack the first time the water wheel hits a timber jam."
The blacksmith tilted his wrist, a thick, silent stream of grey-white metal sliding into the narrow throat of the sand-mold. The heat was immediate and dense, smelling of parched river-sand and roasted linseed oil. As the lead filled the channels around the iron valves, it began to shrink slightly, its brilliant sheen dulling into a leaden, stony grey that absorbed the daylight.
Victoria walked down from the storehouse lane, a basket of dried salt-fish on her hip, her linen apron dark with the blue ink of the new scrip validation logs. She stopped by the bench, watching the metal solidify with the quiet, skeptical focus of an auditor whose tallies were being altered by an unseen hand.
"The carters from the northern track have returned, Thomas," she said, her voice dropping beneath the steady, rhythmic roar of the primary boiler on the ridge. "They didn't go to the crossroads. They say three wagons from the lower valley are sitting by the boundary stones, loaded with copper wire from the coastal smiths, but the carters won't bring them across the salt line. They say the clerk from Oakhaven told them the King's men are seizing any beast found carrying goods for the Silver Hill."
"The clerk is using the sheriff's book to frighten the carters, Victoria," Thomas said, his thumb scrolling past the raw text files on his display until the interface settled on the financial logs. "He doesn't have the lances to hold the border stones if the Archbishop's proctor is with the teams. Did Brother William send his riders?"
"He sent two clerks with the cathedral seal," she replied, her face tightening. "But they are sitting in the tavern at the crossroads, drinking small beer while the Baron's men count the horses. They say they won't risk the Church's skins for a load of copper."
Thomas locked the screen, the green light vanishing against his leather jerkin. He looked toward the southern pass, where the watchtower on the bluff stood clear against the grey morning clouds. The bell was silent, but the air was changing, turning sharp with the scent of pine smoke and the cold rot of the lower marshes.
He sat on the overturned fuel bin and pulled out the phone again, checking the messaging queue against the dim light of the yard. A new line of characters had completed its journey through the twenty-four-hour drift, the letters appearing crisp and steady on the dark glass.
His mother wrote that the weather had cleared by afternoon, leaving the garden damp and smelled of wet earth. She had spent two hours in the basement clearing the old storage shelves that sat beneath the water meter. She found his old software engineering graduation cap—the one with the heavy blue tassel he'd left hanging from a pipe behind the furnace. She mentioned putting it in the cedar chest with his father's winter coats, noting that the house felt very still now that the neighbor's boys had gone back to school. She closed by telling him to keep his socks dry.
Thomas rested his knuckles against the cold timber of the bench, his mind tracking the simple, distant routine of her house. In Denver, his mother was sorting through the small, discarded textiles of an academic life that had already been overwritten by the iron and coal of Argenton. To her, his absence was a matter of a long semester or a distant field contract in the mountains; she didn't know that the graduation cap she was placing in the cedar chest belonged to a future that was being unmade with every strike of Wat's mallets.
"Thomas," Elias said, coming through the gatehouse arch with his long ash measuring rod over his shoulder. His fingers were black with the charcoal he used for his field sketches, his leather kirtle spattered with the pale lime-dust of the lower wall foundation. "The masons have finished the setting for the secondary flume. Hamo says if we don't drop the new axle into the housing before the noon bell, the mortar will go dry in the joints and he'll have to scrape the whole course back to the stone shelf."
"The axle goes in now, Elias," Thomas said, standing up from the bin, his cloak catching on a rough iron staple at the edge of the bench. He reached down and picked up one of the new, twelve-inch lead sleeves from the sandbox, the metal heavy and cold, its weight distributed perfectly across his palms. "Wat, get the boys to the pit. We're going to set these bearings three ranks deep, and if the Baron's men are still writing names at the crossroads by sunset, we'll show them how much weight this lead can hold before the water turns the wheel."
