Another thing that can be done, and I've done several times with both Shimano and Phil BB's that kept working loose, is get a locking ring from an old three-piece BB set, torque the NDS cup to where it feels right, hold it in place with the BB wrench and tighten down the locking ring on the few threads that remain visible outside of the BB shell with a locking ring wrench. Loctite, Teflon tape, or whatever can also be applied on those threads before installing the locking ring.
