[modeleng] Levelling problem.... what to do?

Hi folks,

Having got to the "almost finished" end of the workshed conversion on a 
sectional garage I've hit a snag...

The milling machine base seems warped, it doesn't sit squarely on the floor.... 
or rather it doesn't sit squarely on the small concrete pier I built for it.... 
I don't think it's the pier as the top surface (inside a fence of bricks) is 
levelling compound and checks with a straight edge and a level could show no 
discernible deviation from flat and true....

I'm not in a position to bolt it down, there isn't enough depth to the pier 
before I hit the waterproof layer to get anything with serious pull, I do have 
some anchors that will stop it travelling though... should I pack the wobbly 
corner and live with it and hope it doesn't affect the rest of the machine?... 
the Knee is off ATM so I'd have to go from the knee shears to work out what 
should be flat.

The base of the mill is a hollow cast-iron casting integral to the rest of the 
column.... I find it hard to believe it's distorted.... but it's the only 
answer I've got ... unless I've trapped a big lump under there....

Eek...
