Update: The drive lugs get in the way of a safety disk or ring or
anything else. Epoxy looks more promising; just a semi-permanent solution.
Note: Epoxy can always be removed with heat or chlorinated solvents but...

Back again;
Since crawling in under the spindle is difficult for an old stiff guy
I laid the iphone on the table and took a pic, rotated the spindle 45
degrees and took another; nothing useful moved. However, there are
large socket head cap screws around the perimeter of the spindle. It
should be possible to make a safety cap that has a few thou clearance
to limit axial movement. 'Maybe' I can jury rig something. Basically I
have to see what kind of clearances I have. An actual thrust bearing
seems like asking for trouble.
Psychologically it would almost be easier to pick up the radiator cap
and run a new(er) one in. Still that brings all sorts of problems of
its own. Hard to win.
Back to the drawing table. ;-)

A couple of solutions present themselves but neither are ideal.
Simply use the M6 shcs that hold the dogs in place to secure the CAT40.
Balance and adequate strength/safety would seem to present problems.
Does the nose have any extra holes? There are 4 threaded holes with no
obvious function on my 30INT spindle and looking around the internet I
see threaded holes in some of the CAT40 spindles.
It seems that you could use those to hold in a custom ER40 (or
similar) adaptor.
4000 rpm probably isn't fast enough to need to worry too much about
balance.
