To quote David
'The big ball (as Tony puts it) is adjustable. There is a serrated brass ring at the rear secured by two bolts. Removing the two bolts enables the ring to be turned to take up any slack. Make sure after adjustment that the mounting does not bind on the ball at any point. You can check this by releasing the lower mounting (cap nut and a very thin locking nut) and moving the top mounting to an fro'
There is often wear in the threads of the serrated ring such that after careful adjustment, when the 2 bolts are tightened the big ball locks up.
