Thank you everyone for your advice. I have still made no progress: this one is extremely stubborn and if I apply much more strength, I might experience a hernia but I am going to visit an engineering pal of mine and then see what he can do in his workshop.

At least I am not isolated with this problem: it seems many others have had the same and it might be worth updating the idiot's guide to stripping the Premier 2.

Anyway, I owe many of you a pint. I am hoping to attend Binners' Kempton event, so would be delighted to put faces to the names.

Best rgds to all
Andrew.
