{ "id": "s1", "narration": "Every part I have ever held off a press was born fighting the weather. A forty-eight inch fixture of 6061 aluminum moves a little over seven thousandths of an inch when the shop air swings twenty degrees, and I am held to five. The metal does not want to hold my numbers. It wants to breathe." },

{ "id": "s2", "narration": "Coefficient of thermal expansion. A material property, studied by mechanical engineering, that describes exactly how a part changes size with a change in temperature. Steel stretches about six and a half parts per million, per degree. Aluminum nearly doubles that. My stock is a lung, expanding with every degree of heat that rolls in at noon." },

{ "id": "s3", "narration": "So we do not fight it blind. We machine to the shops temperature, not the blueprints. Warm-up passes on the spindle, so the thermal steady state is my baseline. We measure the part warm, because warm is what it will be when it goes in. Cool on the press, not the counter, or it twists." },

{ "id": "s4", "narration": "The same law that drifts a bolt snug in July and strips it in January is the law that steams the enamel off a sous vide bath. Precision is not a static number. It is a conversation with the temperature of the room. Get the room honest, and the part, and the dinner, come out true." }
