Further to massive vibrations, your mount has back lash if your system actually generated enough dynamic or sinusoidal action like that of foot fall on a large concrete plate enough to make it "vibrate" it would affect your system irrispective of if you had a 1x1m titanium pier...
Further more to this if there was that much "vibration" then how the hell do us mear mortals that rely on a set up every time with a tripod get away with the images we do.... Mike sidonio sure as hell doesn't have a bolted down pier...... Neither do I and i can show you alot of photos taken on a pier i design and built that runs a RC... its clear of the ground by a long way on bolts..... it doesn't suffer from vibration. The only time you might even take a punt at figuring something else out is if your running at the F15+ focal length.... how many scopes you see around that people are using at that F ratio
unless you can quantitively show me your vibration apart from the old hammer on the side test which means nothing because it doesn't happen then I stick by what i say!
