In disgust at their bearing slackness, I packed away my Unimat milling heads and tried to forget about them. Perhaps motivation will now return... When you had the quill apart, did you investigate whether a standard-sized ball bearing could be fitted into the nose end of the quill as well? Presumably, it would need to be bored out, as at t'other end.

I see that Simply Bearings (from whom I've had excellent service) have 15mm ID bearings in 20, 21, 24, 26 and 28mm OD. Perhaps this makes a nose-end bearing swap practicable. What do you think? My spindles have a lot of radial play at the nose end, so I'd want to attack that end as well.
