I am impressed Jon. How did you jig the grinder to control the attack?

done it free hand , went down with the grinder till just the very bottom of the threads were left, then set calipers to 8mm ( screw still turning with drill) and used file to take it down the rest .. checking with calipers took about a hour to do .... happy with the result
should eliminate endfloat with thrust bearings
