May I take you are all as much in the dark about it as I am?

You may not. Get thee to a library, or consult with Prof. Michael
Chinnery of Brown University, Rhode Island, who wrote a brief analysis
of the Chandler wobble and it's possible causes many years ago for the
Open University course book 'Understanding the Earth' published by
Artemis press.
A further source is 'The rotation of the Earth', W H Munk & G J F
MacDonald, 1960, Cambridge University press.
I am aware that these refs are somewhat old but they come from a period
when my interests were less focussed.
