Thanks for the pics. Can you draw an X on the picture of the whole tree where exactly the wound is. Now I've seen this, I'm sticking to my calculations but I'd use more cobra cables. One attachment point on the block with a V shaped double splice or ring splice approx. five to six meters from the tree to get more anchoring points. I'd brace it as high as possible with less pre-tension, say about 250 to 500 kg's.
When using these big concrete blocks, they can be used to do some more cabling for the rest of the tree when the situation gets worse in time. So no need to pour any more blocks further on. Gotta look ahead.You say you stand on the mark where the block must be poured, but remember you'll need TWO blocks. Depending on where the mark of the wound is, I'm guessing you're cabling too low.
