      "value": "1. Select a steel round bar (material 16MnCr5) with diameter at least Ø35.4 mm and length at least 70.5 mm to allow machining allowances.\n2. Mount the bar in a three-jaw chuck.\n3. Face the end.\n4. Finish turn the holding diameter Ø33.4 mm over length 14.4 mm (from Z=0.0 to Z=14.4).\n5. Mount the bar in a three-jaw chuck by the holding diameter Ø33.4 mm.\n6. Face the end and set Z=0.\n7. Rough turn the remaining outer surfaces leaving ~0.5–1.0 mm stock per side for finishing.\n8. Finish turn diameter Ø30.0 mm over length 51.1 mm (from Z=0.0 to Z=51.1).\n9. Break all edges (e.g., 2×45° where applicable).\n10. Remove the workpiece from the lathe."
