Mike,  I think if you support it from the ground it will vibrate the  
whole column.  In the early 90's we had a Amray 1700 Turbo system.   
It used a bellows and a thick rubber sheet that wrapped around the  
bellows fastened by hose clamps,  The orientation of the rubber and  
position of and tightness of the clamps would minimize vibration  
transferred to the column.   Owen Mills
