Why not put some rubber inside the rod to dampen  it? That's that is done on 
golf clubs and it works well.

Jerry,
 
I had two servo gears stripped from the harmonic vibration  using the 
MK elevator bellcrank. A support of some kind (foam,  balsa) halfway
along the rod is a must. First time I was able to save the  plane, not so
the second the second time. And it was inverted  too.

I’ve mounted the  bellcrank and will use Central’s carbon fiber push rod.  
The pushrod  length from servo to crank is about 28”.    
Is it necessary  to install a support of the rod  halfway down the fuselage 
to prevent  flexing.  And if so does anyone have a simple way of doing this  
inside a fiberglass fuselage? 
TIA 
Jerry
