Could you explain this wedge method more clearly? I don't quite get it and I don't know what else to do.
PLEASE DO NOT!!! The wedges press against the perforated sheet metal(vent plate) and will likely destroy it and you will still be left with the stubborn hub(s).
OK with the set screw(s) out apply penetrating fluid into the set screw holes and let them soak.
After they are so prepared, apply torque to get them to free themselves from the shaft. Anything that will apply great torque without damaging either the hub or the shaft should do it. Channellocks come to mind. Also vice grip if necessary. Last resort
a big pipe wrench!!! Alternating direction may help.
Realize the hubs are replacable, the shafts not as easily($) so.
