Thanks Paul. Your guidance and support on these RCs has been really helpful. GSO owe you.
I've now eliminated the clips - as they don't serve any purpose. My baffle was very loose for these tests. As you know, the baffle makes no contact and applies no pressure to the mirror itself. It threads directly into the removable locking ring. I've seen no difference in star shapes based on a tight vs. loose baffle. That's been my experience...
P.s. now, if the locking ring isn't locked in place by the two grub screws, and further turns of the baffle result in further turns of the locking ring onto the primary - that would pinch for sure. The best way I can explain the baffle on these, is that it just threads into and essentially becomes an extension of the locking ring. It's the locking ring itself that makes contact with the primary and presses down on it, by way of an o-ring.
