Well alot of suggestions, some ok but most obviously were generalized from other equipment/scenarios(keep shouting wrong answers till they are right!!). No heat was involved, although it was probably 45 here today.
I tried 'adjustable type filter pliers', not enough clear real estate to grab the ring with the amount of force required it needed to loosen it(this time).

Followed that up with an Amazon order or some rubber strap wrenches, 2 for $19.99!!

The smaller one worked. Remember it's the silver ring that needs to be loosened, not the entire bowl! Not exactly easy, but the smaller band was able to be negotiated around the various obstructions. To say that ring was tight would be an understatement. Took some effort but she spun loose and all is good.
