What the thread found

• When a gimbal maintains balance in one orientation but tilts after rotating 180 degrees, the problem is typically misalignment between the pan axis and tilt axis rather than poor dynamic balancing technique.
• Pan axis misalignment can sometimes be corrected by installing shims between the pan housing and yoke to move the axis into proper alignment.
• Worn or improperly adjusted pan bearings can cause balance problems that shift depending on gimbal orientation, as opposed to consistent tilting which suggests axis misalignment.
• Over-tightening the retention pins on pan bearings can pinch the yoke and distort the gimbal alignment; gradually backing off and retightening these pins to remove slop without binding can restore proper centering.
• After correcting gimbal axis alignment through shimming or bearing adjustment, the sled should maintain consistent balance regardless of its rotational position during panning.

Depends on

• The thread discusses home-built gimbals and lower-cost commercial models like Flyer LE; alignment procedures may differ for higher-end professional gimbals.
• Specific torque specifications for bearing retention pins were not provided in the discussion.
• The solution of using shims and pin adjustment worked for the participants but may not apply to all gimbal designs.
