... unless my dislexia has just cut in, I believe the rotation of the blade should have the tendency to tighten the nut rather than loosen it.

When the blade is cutting the forces are trying to tighten the nut. On the other hand, if the motor were to slow down fast (and you all keep mentioning a brake?), then the momentum of the blade would try to spin the blade and loosen the nut.

I’m not aware of any brake on a TS, but I’m no expert. My experience is the motor and blade take quite a long time to come to a stop.

I’m with pinto, I’m wondering if the nut is being threaded on far enough. While a 1/2” dado is not that large, the washers are usually really thick and in general I don’t think are used when using a dado stack.
