Many thanks DaveD .....
I went back to this as mine was already tight from factory.
While rotating the model - I detected a very slight movement of the arm indicating it was not seated right. i could actually rock the arm a tiny amount which to a camera would be huge !! I also saw a rubbing arc mark on the gimbal base showing the arm was not correct ...
I slackened the screw ...
made the arm seat fully DOWN and then tightened up ... all noise now dissapeared from gimbal - its silent now ! The arm does not move except as it should. All I need now is weather to improve so I can go out and test.
Many thanks DaveD and also to forum for bearing with my questions.
