Carefully mike the spindle, accurate to .0001 or so if you can.
Compare your measurement to this chart:

If the spindle is in tolerance, buy new bearings. If it's oversize,
new bearings won't help; you'll have to hone the spindle a bit.


Which you might well do in the lathe.

BTW, I suspect a lube problem. My Smithy is now over ten years old with
no bearing problems.

Certainly some sort of defect. Given the fact that I only use it
occasionally and that there was bluing I think the bearings were
installed way wrong.

Now I just need access to a mike that'll span over an inch and is good
to a few tenths.

Or I just buy new bearings and fit them up...
