First align the column perpendicular to the X-Y plane, and then align the spindle perpendicular to the X-Y plane. If they are off, then you would expect results similar to that described.

- It might be worth checking for play in the spindle head. The bearing may
need to have it's preload nut tightened. I say this because I was having a
similar problem with my Taig manual lathe. I had to tighten the nut a little
to fix the problem. Before that I was tearing my hair out trying to figure
where the movement was coming from. Hope this helps...
