Stuck square taper cartridge BB - any bright ideas?
One cup is plastic and the other alu in a (battered) 1997 steel frame. The plastic cup obviously frigged itself when challenged, shedding all its teeth, so I've drilled and milled it out as best I can with a Dremel. I've spunked WD40 into the area of the aluminium cup several times since before Xmas and tried several times with a 3-foot pry bar. It's managed to kill one cheap Cyclus(?) tool so far.
I've also tried hammering the cartridge out of the alu cup, but I don't think it's moving.
Where next? Caustic? Plus Gas? Liberal application of heat?
