Pm932m-y Tram Off .003 Over 4"-y Gib Adjustment?

Well it turns out that after I squared up my X, I'm only nodding .001" over 6" in Y. Checked by sweeping and with a spindle square. That .001 bothers me but I'm not sure it's worth lifting the column to attempt getting it perfect, at least not right now. Thanks for the help all!

I would agree with you that chasing .001" over 6" is not worth chasing. I got my mill to .0015" over the width of the table in both X and Y (9-1/2"). I probably couldn't measure what effect this would have on most of the parts I make.

Are you sure you need a hoist? I was able to tilt mine enough to slip shims under the front of the column by pushing with my left hand and using my right to insert the shim. Not that hard just be sure you only loosen the bolts, not remove them. I backed the front bolts off a lot and the rear only enough to allow the head to tilt. You aren't lifting the head, just tilting so shouldn't require a ton of force.

I agree with sanddan that is how I done mine.
