Desperation Station:

1)? Apply enough plumber's Teflon tape to the spindle to make it quite difficult, but not impossible, to tighten the chuck against its stop;
?
2)? Take many light cuts;?
?
3)? Run slow enough to be able to intervene and stop the chuck when/if it starts to back off the spindle.
