What the thread found

• Commercial hardmount adapters for Merlin/Pilot arms to Mitchell mounts include the Tiffen Flyer Vehicle Mount, though it is expensive.
• The Merlin and Pilot arm-side socket block is compatible with the Flyer vest socket block but not with professional socket blocks.
• A DIY hardmount can be constructed from aluminum bar stock with drilled holes to engage the arm connector and tapped holes for fastening, then mounted to extrusion and secured with G-clamps to vehicle structures.
• DIY hardmount installations require extensive safety precautions including operator harnesses, door wedging, and skilled vehicle operation.

Depends on

• The Tiffen Flyer Vehicle Mount compatibility was not verified in both directions.
• DIY construction requires machining skills and carries unknown structural and safety risks.
• Mitchell mounts are standard on camera cars but may not be present on all shooting platforms.
• The DIY approach described had limited testing and the builder noted viewing angles can be constrained by vehicle door positions.
