leveling a lathe.

>I think my lathe has more vibration than it should. I have a powermatic 3520 with $300 lbs of rock under it. It does pretty well but sometimes I feel like I should be able to run a fairly small piece at higher RPM and not get that little vibration. I know the wood can be out of balance just because of the nature of the beast but i would like to keep the vibration to a minumum.

Here's my question. I you just crank the feet down until the machine doesn't wobble is that enough? Would it be better to level it in both planes? I know my floor isn't perfectly level or flat. I've heard machinist's talk about this and wonder if it not only would it keep the lathe running true but might reduce vibration.
