After hours of measuring, thinking and research, I finally ordered the parts needed.
It is now time to disassemble the piano!
First slowly removing the tension on the strings. There are 222 strings on the Steinway O, with an overall tension of around 20 tons. Yes 20 tons! To avoid too much stress on the iron frame and the soundboard I removed the tension step by step. First by tuning down to a semi tone flat, then a few days later another semi tone...and so on until the whole tension was removed.
Meanwhile I could take it apart...
