Thanks for sharing, Torsten, I'm sure your answer will help someone one day! IIRC my first attempt was the same as yours, then not having a more suitable yarn at hand I tried the "brute force" method. It worked fine so I'm sticking with it :-)

These hard-to-open cases drive me crazy. I am the exact opposite of handy and even trivial mechanical fixes are on the brink of impossible for me. Detailed procedures created by experts and follow-up success stories like yours give me - and maybe others like me - the necessary courage. I managed to open and fix a Spice and a Pioneer (thanks to Logan West). What's ahead of me is a 28s, I have one with bad keyboard contacts but Geoff Quickfall's description scares the hell out of me...
