Use a hacksaw blade to carefully cut through the threads of the BB in 2 places then it will just fall out. Easy as that...
chiroshi-
I'll have to have a look come Monday regarding the drift/screwdriver and I'll bring a hacksaw blade along as well in case that doesn't work....The bike is languishing at work until then and I'll have to take the cranks etc of 1st to get in (no tool with me today) so I'll give it a go then.
Cheers for the suggestions...

Hey, The drive side bottom bracket cup on my Carlton has sheared off, and about 2/3's of it is stuck still threaded inside the frame. There is nothing protruding outside of the actual frame, so nothing to get a tool on at all.
Just wondering if anyone know of any magic tool or method to get hold of the broken part, in order to remove it from the frame....?
Or is is a case of a frame builder replacing the bottom bracket shell....? (in which case it is possibly not worth the expense....)
Cheers for any ideas....
