Many thanks for your reply.
The DRO does not change when tightened, with either the feed all the way up or all the way down. I took the motor head casting off to have a look at the bearing, and there appears to be no play there
You can however wiggle the top of the spindle when in the up position. From this, it sounds like the same problem you had.
Do you know if the parts list for the xj-20 is relevant to the 25? I'm still trying to gain an understanding of the actual structure of the quill/spindle, and bearings.
On one forum (can't find it now) the writer suggested he would have the mechanism hard chromed, then reground to fit.
Cheers
