• Thanks for both the above. As there's no brake on the front of it I wouldn't be able to loosen it off against anything, however if I can get it to turn that might free it up enough to then tap out, or I suppose I just spin a brake calliper onto it. Only concern is that tapping in a torx/6mm bit might drive it even further into where it's currently stuck.

    Will give some attention this evening and see how it goes, would rather avoid paying an engineer.
