safety he would be risking if the part failed under load. Jonah had no answer that satisfied either of them. They painted a broad white mark across the casting, wrote "REJECTED" in the notebook, and placed it on a separate shelf reserved for parts that had taught them why saying no was sometimes the right decision.
Those rejected parts were the hardest for Jonah to accept. It was easier to imagine that patience could fix everything than to admit a limit, especially when the entire point of his winter project was finding value in discarded machinery. Silas told him that skill did not mean believing every object deserved another chance in service. It meant recognizing the difference between a part that could be restored to a tested function and one whose remaining weaknesses made the risk unacceptable.
The lessons began changing Jonah in ways that had little to do with engines. At school, when a classmate's small engine project would not start, he listened to the symptoms instead of grabbing the nearest tool. On the farm, when a bearing began making an unfamiliar noise, he asked Dale to inspect it rather than insisting he already knew the answer. His father noticed that the boy was becoming less eager to prove himself and more willing to admit uncertainty, although Dale still did not connect that change with the mountain of broken castings in the shop.
One afternoon near the end of February, Roy Duffy visited the farm to discuss a replacement hydraulic component Dale had ordered. Roy was the regional representative for a farm-equipment dealer and had a polished way of explaining expensive purchases that made them sound like ordinary maintenance decisions. He wore a clean winter coat, carried catalog sheets in a leather folder, and knew the factory part numbers for the International almost as well as Silas did. On his way back to the truck, he noticed Jonah carrying an old engine block through the shop door.
"Still collecting those?" Roy asked. Jonah nodded and explained that he was studying crack patterns and mechanical repairs with his grandfather. Roy raised his eyebrows, looked toward the rows of damaged iron, and reminded him that replacement castings came with known specifications, manufacturer support, and far less uncertainty than a homemade patch.
He was not entirely wrong, and Jonah knew enough by then to acknowledge the point. "Some do," the boy said. "But some parts can't be found anymore."
