My Bike is fixed and it is alive again!
Turned out I did need a new derailleur, the old one was a bit to damaged. In the end it cost me $50 for a frame straighten, rethread/Helicoil, Alignment and new derailleur. Overall not bad.
The old derailleur and stripped thread.

Cleaned the bike for the first time in years to match the cleaned up frame near the new parts.
My dog jumping in a shot, yes he has two different coloured eyes just like David Bowie
This is where the derailleur came off last week (the small track on the right around 10 metres in)
I ended up doing a 12km ride all is working but the derailleur needs some adjustments so it changes gears better.
