    Bill Morris:
    
    Further correction (I was not being precise enough):-
    
    I can only conclude that the very slight leeway in the shaft end-float is the
    problem still, being completely convinced (though not proven) the sector to
    worm gear is adequate....
    .... and that friction of the gearing, particularly of the the helical gear on 
    the worm shaft,  keeps the shaft slighty one way, then the other depending on 
    the direction of rotation.
    
    I also note my e-mail address did not transcribe (?).
