So following on from this thread: Post in thread 'What Did You Buy Today?' https://www.hobby-machinist.com/threads/what-did-you-buy-today.55645/post-1120587 having got the spindle out, it seems the upper and lower spindle bearings are fine.
The rock and roll appears to be on the two spindle pulley bearings. The other problem I think is that the spindle sleeve seemed to be a bit loose and lack support.
There seems to be a poorly implemented quill lock (not sure, other than locking for transport, what use that would be in a drill press; it's not a milling machine). It's a 0.30" grub screw that is threaded into the side of the head and engages with what I initial thought was a keyway in the spindle sleeve, but is actually there for the grub screw to ride in.
So I was thinking I could knock up a small brass gib to run in that 'keyway', held in place by a couple of extra screws and two little steel 'fences', with the existing grub screw to push the gib against the bottom of they keyway (which is quite nicely machined), it should provide a bit of extra support for the spindle sleeve.
I'll post a few pics in a bit when I'm back in the workshop.
