RE: Supporting carbon push rod - and vibration
the best way to kill the vibration, if I understand this problem correctly, is to put some foam rubber, similar to what the radios come packed in, inside the carbon fober rod (assuming that it isn't solid). This is what is done with golf clubs to reduce the transmition of vibration. It reduced vibes in steel about 98%, Sensicore if any of you play golf, and I'm sure it will do the same for carbon fiber or graphite.
