    Look for magneto bearings, they are the smaller versions of angular contact bearings

    going to attempt to grind down screws to 8mm then use skate bearing .. with thrust bearing either side , on evilbay thrust bearings for 1.90 each

    cant find angular contact bearings at 8mm, and magneto bearings are 6 each ....... i am after all scotsman

    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
