Adapting a used Steadicam Ultra Arm to fit a Proline Vest and gimbal with mismatched post sizes

What the thread found

  • The arm-to-vest connection should be purchased rather than fabricated, either used or new from the manufacturer.
  • A post adapter can be designed in two parts: a clamp that holds arm posts of various sizes while floating between the end block shelves, with Delrin or Nylon flanged bushings to maintain centering.
  • The manufacturer offers a ready-made arm post that is sized to fit both Ultra arms and gimbal types like EFP, 3A, and Pro models.
  • Using multiple standard-length arm posts with an adjustable adapter allows flexibility for different operator heights without requiring a single custom post.

Depends on

  • The specific part number mentioned may no longer be in stock or available.
  • The two-part adapter solution requires fabrication knowledge and appropriate materials.
  • The ready-made post solution sacrifices adjustability for convenience and speed to deployment.
