Thanks,

Just be careful because of the line voltage hazard. I typically work with low power battery circuits myself. A real variac can be expensive as they are a variable transformer. If you go the cheap route with an inexpensive light dimmer I don't know what will happen. I think you will be ok but there is the possibility the back emf from the relay coil would impact the dimmer circuit. I guess you will have to experiment :).
