Paul,
The CN link will give you a rough idea. In your case the closest match on the table looks like 48 inch high, 8.4 inch ID results in a 1.5 arc sec deflection if you push on it with a 5 pound force.
Bump it up to 10 inches = 0.6 arc sec
Bump it up to 12 inches = 0.0 arc sec.
Of course this is very rough, but it gives you the order of magnitude which is all you need to know when deciding how big the make the monster.
