500mm 5,6 Arcaswiss tripod plate

Hello,
I use a Cotton-Carrier harness to carry a Lumix S1II + 500 5.6 Sigma + TC while hiking.
The tripod mount is too short to attach both the round Cotton-Carrier accessory and the whole assembly to the tripod/monopod (Arcaswiss/Gitzo).
The screw centers of the mounting bracket (TS-151) towards the lens are 11 and 25mm (measured with a ruler ;) )
I'm looking for an idea to be able to mount the lens on a tripod/monopod without having to disassemble the round Cotton-Carrier accessory...
Thank you in advance for your suggestions.
 
This is the answer from Gemini:

That's an excellent question that often comes up with the Cotton Carrier system!

The round accessory you're referring to is likely the Cotton Carrier Camera Hub (or similar hardware like the Flat Hub or 10-Degree Hub) which screws into your camera's tripod mount.

Since the Hub is designed for the Carrier's vest/holster system, you generally cannot attach it directly to a standard tripod head.
To use your camera on a tripod without removing the Cotton Carrier Hub, you need a specific accessory from Cotton Carrier called the Universal Tripod Adapter Plate (or similar adapter).
Steps to Attach to a Tripod

The general solution involves adding an intermediate plate, essentially creating a "double quick-release" system.
Method 1: Using the Cotton Carrier Universal Tripod Adapter Plate
This is the most common solution recommended by the manufacturer, as it integrates the system.

* Mount the Tripod Plate to the Adapter: Take your tripod's existing quick-release plate (e.g., an Arca-Swiss dovetail or Manfrotto RC2 plate) and attach it to the Cotton Carrier Universal Tripod Adapter Plate using the 1/4"-20 screw hole provided on the adapter.
* Mount the Hub to the Adapter: Screw the Cotton Carrier Camera Hub (the round accessory already on your camera) into the dedicated central hole of the Universal Tripod Adapter Plate.
* Attach to the Tripod Head: Now, the entire assembly (Adapter Plate + Hub) functions as your camera's quick-release plate. You can simply clamp this assembly onto your tripod head.
* Result: Your camera now has two attachment points: the Hub for the Cotton Carrier harness, and the Universal Adapter Plate for the tripod.

Method 2: Using the Hub's Tripod Thread (Less Ideal)
Some versions of the Cotton Carrier Hub hardware have a 1/4"-20 threaded hole milled directly into the side of the hub (the circular part).
* Unscrew the Hub: Temporarily remove the round Hub from the camera body.
* Attach a Standard Quick-Release Plate: Screw your standard tripod quick-release plate into the camera's tripod socket.
* Screw the Hub onto the Tripod Plate: Screw the Hub into one of the available screw holes on your tripod quick-release plate.
* Result: This allows the Hub and the Tripod Plate to be on the camera at the same time, but it often makes the entire assembly off-center, potentially losing the quick-release functionality of your tripod plate. This method is generally avoided in favor of the specialized Universal Tripod Adapter Plate.

In short, if you want the best integration and functionality, you will need the specific Universal Tripod Adapter Plate accessory from Cotton Carrier.
 
Thank you very much. I can see this intermediate Cotton Carrier piece. The assembly of the 2 Cotton Carrier pieces on the 500 mounting bracket is quite ugly ;). I wonder if I should not simply buy this Arcaswiss Cotton Carrier intermediate plate and drill it (with the 2 necessary diameters: crossing and shoulder) with 4 holes respecting the center distances of the 500... This could improve comfort with the Cotton Carrier (material closer to the body) and lower the assembly onto the tripod/monopod, but there would no longer be room to pass the fingers to make a handle...
