Case wobble during rotation does not necessarily indicate a problem. The neck of a cartridge case is, in essence, a narrowed section of an extruded component and is not always perfectly coaxial with the body of the case itself.
The motorized neck-turning tool manufactured by 21st Century Innovation is specifically designed to handle this scenario. A flexible joint functions much like a human wrist, allowing the system to compensate for any misalignment in the case body while keeping the neck perfectly aligned with the steel pilot rotating inside it.
This ensures that the turning operation follows the axis of the pilot, promoting consistent concentricity and preventing any misalignment from causing uneven material removal around the circumference of the neck.
What matters is not so much whether the case body appears to wobble, but rather how the system manages that movement—maintaining precise alignment between the pilot and the neck throughout the entire cutting process. This explanation should clarify things for those who might fear a defect, as well as for those who do not perform neck turning—or perhaps perform it incorrectly.
Use a Delta No Oil Neck Turning L**e , water based L**e,non-greasy, non-fouling l**e that doesn’t need to be washed off and helps facilitate consistent bullet seating. The goal? Better process consistency and lower SD, where every detail matters.
That’s what I’m talking about. I shoot F-Class, where precision and consistency are everything. I’m not out here hunting turkeys. 😉😁😁😁
