What the thread found

• Hollow aluminum posts with 1/8 inch wall thickness eventually bend or crack under heavy loads, particularly when using long handles or flying heavy sleds in low mode for extended periods.
• Stainless steel arm posts bend under load but do not crack or fail suddenly like aluminum does, providing predictability in failure modes.
• Solid arm posts offer better strength than hollow posts and can be designed with a shallow drilled cavity at the bottom end to allow mounting on arm dock hangers.
• Material choice involves tradeoffs between weight and durability, with hollow aluminum being lightest but least durable under demanding use.
• Precise diameter tolerances matter for proper fit and function of arm posts across different gimbal models.
• High strength aluminum alloys like 7075 present an alternative middle ground between standard 6061 aluminum and stainless steel.
• Carbon fiber tubes represent another material option for arm posts.

Depends on

• Discussion focuses primarily on Steadicam PRO arm compatibility and does not fully address other gimbal systems.
• Specific weight limits and torque requirements for different configurations were not quantified in detail.
• No comprehensive testing data comparing all material options under identical load conditions.
• Solid post drilling specifications for dock compatibility require confirmation of exact measurements.
