Unwanted Table Movement

I've leveled the mill with a Starret #98 machinist level.

Its in Tram, and a slight "nod" was corrected by tightening the gib on the Z axis.

I've confirmed that the table is raising as it moves along the Y axis towards the column. This was measured from an indicator in the spindle, an indicator on the column and one on the head.

Any ideas how to fix this? Tightening the gib for the Y didn't help.

Seems like that would indicate that the table thickness is not consistent.

Or perhaps the saddle was machined with a tilt.
Either way, fixing this is going to be expensive.

I still vote for a tooling plate.

I'm beginning to think a tooling plate is a good idea too.
