Hi Project,

Thanks for the reply.

I have my mill in pieces at the moment, so I can't test much, perhaps in a few hours.

I have a X2 Mini Mill, the X3's baby brother. Yes, there is the potential for some slop in the Z especially if the Gibs are not tightened correctly. When I have everything back together I think I will tighten the gibs, starting at the top and work my way down. If there is an issue, perhaps that will pull the top in first and cause the head to be straight instead of leaning forward. This all seems to be somewhat of an Art.

Best
Phil
