Hi Dave,

 

If you remove the boom and find the balance point of the boom you can
re-attach the support wire at or very near that point.  This will remove the
vertical force on the pivot and allow it to sit in place.  Another option
would be to remove one weight.  Removing the weight would also help to
increase the damping effect.  With 4 pounds of weight in my experience you
will not get enough damping with the 1 small magnet.
