    Dunc,



    I had this very problem. I agree with Ian and Jon.



    The force on the lower shaft might well be distorting the fan frame a little, and it only takes a bit of movement in the frame to give an amplified movement at the pulley - the 3x effect.



    Have a look at the pictures on my website:

    to see the extra diagonals I added on to brace it properly.









    Regards,



    Richard E.
