Lest we forget, the Rodenstock behaves quite differently on the Z system cameras. Infinity focus is a breeze.

Adapting the Rodenstock 100/1.6 to the Z system is very simple. I just added a 65-65mm helicoid (17-31mm extension) with a Z mount on the rear end and a 52mm thread in front, since my Rodenstock already had a 52mm thread adapter fitted. Alternatively, I could have used the rear stock threads on the Rodenstock which I believe are 2" (48mm).

It looks simple.

But I made the most fatal error possible.  I glued the mount on the wrong side of the helicoid.    Nothing is possible any more.  The glue is too strong to correct the error.  And it is not possible now to connect the lens, to the moving part of the helicoid...

 I gave up...

Tried heating in an oven at say 200C? Most epoxy glues break at high temperatures.

I tried that before.  Will give it another go.
