Removing a stuck BB fixed cup?

Am I right in thinking that a fixed cup in an Italian BB shell (70mm width) should unscrew counter clockwise?

If that is correct anyone got any ideas on how to release one that seems to be well and truly stuck?
I've tried the usual soaking in penetrating oil but the fucker still won't budge!

vice up the fixed cup carefully, and twist the frame.

both cups on an italian BB are clockwise to tighten, anticlcockwise to loosen.

If you have access to a vice, vice the BB tool (facing up). then drop the cup down on to the tool. Use the whole frame as a lever, it'll come out.

check you haven't got any lockrings going on first though.

Definitely no lockring just the fixed cup screwed in super tight! Thanks for the advice. I'll pop down to my LBS and see if I can borrow their vice.
