Left chuck on my lathe keeps unscrewing itself ...

[tg_vegas]

Recently, I've had five occurrences of the left chuck on the headstock of my Cueman Deluxe lathe. In each case, the work I had in place was ruined. I have cleaned both sides of the threads thoroughly, and have tightened the chuck down with all the force that I can apply with one punch in both the left and right chucks.

All I have to do is turn on the lathe and wait. Within 5 minutes, the left chuck already starts to unscrew.

Anyone else have this happen? I'm considering using a bit of Locktite Blue but don't want to make disassembly difficult when I take the headbox apart for maintenance.

Regards,
