HP41c display bezel removal

[Johnboy]

Hi All, I want to swap over a display bezel (clear plastic part) on a 41c. I would like to hear from any one who has successfully removed the bezel from a calculator for any tip tricks.

I know the bezel is taken out from the inside of the case, and I realise removing the bezel from a fullnut would be easier than a halfnut, as the fullnut LCD can be unsoldered where as the halfnut needs the whole keybaord taken out.

I'm not sure if the bezels are glued in or plastic welded / heated etc, so hoping to find that sort of information.

Any help would be appreciated.

Thanks
John
