What the thread found

• Major stabilizer arm models like Pro Titan, Atlas, G-series, Master, 3A, EFP, Luna, Silverspring, and Sachtler are generally compatible with corresponding vest systems.
• The connection between arm and vest is standardized through socket blocks, though smaller rigs use different socket block sizes than full-size systems.
• Full-size socket blocks should not be mounted on smaller vests as they exceed the weight design limits of those platforms.
• Arms and sleds connect through pin or dowel interfaces that can be modified by machining different diameters to achieve compatibility.
• Tiffen and CP arms have some incompatibility issues with certain vests, though solutions exist.
• Building a complete rig from individual used components is feasible for those willing to invest time in research and potential modifications.
• Local operators and hands-on workshops provide valuable practical knowledge about component compatibility that archives cannot fully document.

Depends on

• The discussion acknowledges this is not a comprehensive compatibility list.
• Some equipment-specific incompatibilities exist but are noted as having workarounds rather than being absolute barriers.
• Exact compatibility rules for Glidecam and ActionCam systems were uncertain to participants.
• No detailed information was provided about which specific arm-sled combinations create problems.
• The advice emphasizes that direct experience through workshops and consultation with local operators is needed beyond what forum discussion can convey.
