Well, I am now thinking that I may have caused this while mess. I was looking at it some more last night and noticed that with the table all the way to the left, only the back right corner of the saddle is touching. I did mess with the gibs when I first got the machine as I didn't like that there were only 1.5 threads holding the front gib adjustment screw in. I did some filing and sanding on the gib to help it sit deeper so there would be more thread engagement on the adjustment screw. Look as like I may have a go at fabbing a new tapered gib. I am going to play with some shimming this evening to see just how bad I messed things up.
