Any ideas.... Spindle adjustments?

7/16" is a rather large endmill for the Taig (although in this case you are using it more like a flycutter), and .001" depth of cut is incredibly shallow, which can cause it to skip a bit. Add to that that Cold Rolled can be hard to machine, is full of stresses, etc. and you get a difficult situation.
I would probably use the lowest speed on the pulley, more like a .01" depth of cut, copious cutting oil/coolant on the part with a slow feedrate.
