Hi Randy,
                ahhh now there's some words of wisdom that I hadnt thought 
about
before. hmmm but the balance point would be probably right at the weights.
The other seismo's I have seen online  Chris C's one that I have sorta copied,
the SEP, and others, the support wires have been some distance back from the
weights.   Out of curiosity how much weight do you have on your one ?
what are other guys using ?   Gosh I was thinking 4 pounds was nowhere near
enough and would have preferred almost twice that amount.  Thats 
considering the
  Sprengnether I had in NZ had ~28 lbs os mass.

All that being said I could still take the support wires to the other end 
of the frame
holding the coil magnets and gain a bit more ib the balancing act  :)

speak up all   what weights are commonly being used ? and how many of you
considered the balance point of the boom when adding the support wires ?

cheers
Dave

Hi Randy,

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.
