    Ok, this is what I plan to do... the top shows the existing screw, very simple, very crude.

    The lower two diagrams show the proposed 10x2G replacement, with a pair of 8x16x5 thrust bearings retained by a circlip and 12mm washer inboard and an M8X1.0 nut outboard to adjust endfloat. I'll probably extend the outboard shaft to allow me to fit a zeroable micrometre dial with a backing dial mounted on the bearing block.
