Massive fuck off nut and bolt with washers(m12 or 14) through the hole, tighten against the cup. This allows you to use the bolt head to turn instead of the thin bit on the cup. Simples, nut and bolt will cost about 50p.
Works every single time in my experience. Also, soak the bb area in plusgas or jizer to loosen things up a bit.
