But, how exactly helps that with a drill? i mean wouldn't they wobble  
around a bit, break the drills?
I can see how someone would take a shock absorber and modify it into a  
short travel linear slide, but i don't see how the air cushions can be  
used.

By the way, train carriages here use a similar system of very large  
pneumatic cushions for shock dampening - the kind of train you are in  
danger of falling asleep and missing your stop because the ride is so  
smooth.
