Here is the wood pre-epoxy. The crucial branch in question is the one bottom right making the little 'cave' (you can even see almost through it in this photo it's so thin - it looks like it wants to break doesn't it?).
Here is the reinforced version. Can't tell any difference from before except now that branch ain't going nowhere.
That's an excellent fix! I also want to try it on wood in a NanoCube, but I suspect I'd need to use a lot more because the whole piece has gone extremely soft. Am actually looking out for new wood but at this point travelling around the country visiting all the LFS is officially discouraged.
