Of course, its not new anymore as that post was in 2014 🤣
My observation with my mount has been slightly different from almost everyone on this planet. I
I notice that when I hand tighten the RA nut, the axis is way too smooth for clutch to hold it. With clutch locked with enough force (confirmed that it does not touch the stop), I can just pull a cable little bit and it would slip. Balancing is a nightmare.
Now the interesting part. As I would gradually loosen the RA nut, the axis rotation becomes more and more dragged. Ultimately, when its too loose, lateral play shows up.
I have tried setting the RA lock nut up in between too smooth and too dragged, but have been not been successful.
