I just noticed that the pulley on the saw spindle had worked loose due to the setscrew loosening. Fortunately I caught it before any real damage could happen. Should I use one of these locking pastes on the threads to prevent vibration from reloosening it now that I am going to the bother of realigning everything? I build a worktable around my tablesaw so it is a true hassle to work on this pulley and don't want to go back soon again. Or will I be sorry when I want to remove this set screw and find the stuff won't let go as the Allen wrench strips?
