Did you ever find any resolve for this? I received my mount today and messed with it some and that azimuth clutch knob doesnt really seem to tighten up all that much. I wonder what others have experienced with it? does the knob bottom out against the mount body or is it supposed to show some threads when the azimuth clutch is tight? It just seems not as securely tight as it should be.
Thanks,

Yes I got some spare parts. The azimuth clutch is supposed to bottom out against the mount body. When you tighten the clutch it will reduce the inner diameter of the collar seen on the picture. The collar will in turn move a cone at the top of it upwards. This will tighten the RA axis construction. But as far as I can see the construction is such that the axis can be made stiffer but not fully locked.
