Default Z axis squareness

Hi all,

I have a (about 1989) YCI supermax-1 rebel and the head is about 8-9 thou out of tram in the Y direction (tilted forward) and another 3 or so in X. This is measured by swinging an indicator on a 5" dia plate we use for tramming the bridgeports....


Machine has box ways. 6 leveling pads, 4 under the table and 2 at the back of the column. I've taken all the tension off the rear column pads, hoping the machine would flex back with zero result.

Is there any way to adjust the head on something like this? Machine rattles terribly in some not so heavy cuts.

Any advice would be appreciated.
