Thanks Lil Lupe! Yes, I did that myself. Exact four years ago I unfortunately discovered a soft, spounchy bark at this place. It had great bark at that place!
All I could do is remove the bark and the soft tissue under it. My teacher, Manuel Germade, gave the tip to make a kind of flow, so water could get away. I only used some handtools, and time did the rest...
This was right after removing the rotten tissue:
And now, 4 years later, it looks like this. I just treated with some wood hardener, that's all...
