The BB on my steel-frame bike is knackered and I can't get the cranks

From the last time the BB was replaced the bike experienced a transport
across the Atlantic on a ship which probably hasn't helped matters.

Any tricks of the trade?


Another question is, how much torque can one safely put on the crank
puller without risking damage?
