Sharing mounting the sinar copal shutter on arca swiss cameras

[mhayashi]

I’m now preparing for mounting a barrel lens on my arca swiss metric.
Just for sharing, I bought the following adapters made by a Chinese manufacturer called Luland on ebay.

Luland Produced Arca Swiss 141mm to SINAR Shutter Adapter Plate

Luland Arca Swiss 171mm to Arca Swiss 141mm Lens board adapter

My standard is the older 171mm, so I needed the adapter of 171mm to 141mm standard.
You don’t need it if you have the current 141mm standard.

I fitted all the parts. Overall, everything is fine except the extra space between the sinar copal shutter and the shutter adapter.
I need to tape the adapter rim(the rightmost pic in the first reply) to thicken the notch of the sinar copal shutter, otherwise the shutter and the lens tilt downward a little bit, then the focal plane isn’t parallel to the film plane.

I will post the lens mounted on the camera when I receive the TTH series IIe cooke f4.5 325mm lens.

If you mount a sinar copal shutter on arca cameras by any other means, let me know just for my interest.
