They stood talking for another twenty minutes. Roy asked about record keeping, testing, and how Jonah decided which castings to reject, while Jonah asked what manufacturers considered most important when they evaluated damaged components. Each realized the other had knowledge worth hearing. When Roy left, he did not apologize for the jokes he had made at Earl's yard, but he shook Jonah's hand and said he would remember the shop the next time an obsolete casting threatened to keep a customer out of the field.
The call came sooner than expected. An older customer owned a tractor whose replacement component was delayed with no dependable delivery date, and Roy wanted to know whether Jonah would inspect the damaged part before recommending a much more expensive solution. Jonah told him to bring it by but made no commitment over the telephone. Silas smiled when he heard the conversation, because the man who had once dismissed the work as homemade repair was now using nearly the same cautious language Jonah had learned in winter.
The casting arrived with an older farmer who had driven two counties to reach the shop. He told Jonah how the machine had failed, what repairs had been made previously, and how much of the season depended on its return to service. Jonah listened without interrupting and asked questions about the operating conditions before examining the damage. He eventually concluded that the component offered a reasonable repair candidate, subject to inspection and testing, and the farmer left it with him.
Jonah approached the job with the same care he had used on the family tractor. He mapped the crack, reviewed the surrounding material, and prepared the repair only after checking the damaged region with Silas. The work held its controlled test and passed the subsequent checks agreed upon before the farmer put it back into service. When Roy telephoned a week later to say the tractor had returned to work, his voice sounded more relieved than surprised.
"You saved him some time," Roy said. Jonah answered that the part had been suitable for repair and that he was glad it was working, though he reminded the representative to have the farmer continue watching it during normal inspections. Roy laughed softly. "You really can't just take a compliment, can you?" Jonah looked at his grandfather, who was listening from beside the stove, and said he had learned to trust a test more than a compliment.
