    More work on the x sides. Drilling large dia holes by hand in the thick I-beam turned out to be a mission so I made two mdf boxes and drilled it on my small bench drill.




    For basic alignment of the x-sides I used the centres of by ball skrew mounts

    Once aligned I welded in tabs to make re-alignment easy


    Used steel epoxy putty as per Jazz's suggestion for shimming. Worked like a dream. I can't imaging doing a steel home build without this stuff as there's just no way a beginner is going to weld something of this scale together and end up with perfectly square mated surfaces.






    x sides almost done.
