The reward goes to.... ndnchf! I tried many other things, including purchasing every spray known to man, but the solution that worked was the leather + hose clamp (plus two humans, four hands, a hammer and a screw driver).

With the clamp as tight as I could get it, I used a screwdriver and a hammer to tap the clamp screw head sharply and break the knob loose. It worked great. I'm in Fredericksburg, Virginia
