What the thread found

• A bare aluminum arm post can stick when inserted into a gimbal under load, preventing smooth swiveling of the gimbal.
• Using a post collar with a delrin washer instead of locking the post directly on the arm allows the post to move freely within both the arm and gimbal.
• Polishing an aluminum arm post with brass polish can give it a metallic appearance similar to stainless steel.
• A locking collar with an adjustable screw can hold the gimbal at a fixed angle relative to the upper arm segment while still allowing rotation when unlocked, useful for optimizing operator comfort during low mode or running shots.

Depends on

• The discussion involves equipment from 2007 and may not reflect current manufacturing standards.
• The delrin washer solution was mentioned by one contributor but no detailed installation steps were provided.
• No testing or comparison data was provided to confirm the effectiveness of these approaches.
• The locking collar solution was described as an alternative preference rather than a direct fix for the sticking problem.
