Working on removing a stuck Campy bb insert on the chain ring side. Haven't pulled one apart before. Left side came apart fine, but right side seems seized. Want to be sure of the thread direction, I assume it's left hand thread, based on pics I've seen of other such inserts. I don't have a 'correct' bb tool yet, but I haven't heard any encouraging reviews about the Park HCW-4 BB tool for trying to get this off. Tempted to apply some heat but no so much as to melt the silver solder joints. Also may MacGyver some other method. Tempted to thread a bolt and nut through it and try with an impact gun - if the bracket is left hand thread then tightening the nut/bolt should be the right direction to loosen the insert.
Ideas? What bb tool would you recommends? If all else fails I may leave it in and proceed with the resto without removing it.
