Heresy!

The entire Z axis has been translated vertically 4 inches..
oh yes.. you have to cut out the welds and re-weld it.
and then flatten it, after it warps again.

and then, uh, the spindle axis of rotation is still 5.25 inches from the column.
so you have to built this bracket:

... which nearly doubles the leverage upon the Z axis block... and cuts the stiffness down that much further...
