large eucalyptus tree in the corner of our garden which was crying out for something creative being done with
Cut it down, burn it and plant something native. Awful trees!! Your neighbours will thank you 😅
More seriously – I second the advice the others have said about tree species and fixing it to the stems. This is a baaaaad idea.
In my experience, those coach screws aren’t particularly solid, they will snap or shear surprisingly easily – we used to use them or gate hinge plates and could break them by hand with a ratchet. I’d be concerned if/when the tree moves and flexes they will just shear and you’ll be left with a pile of timber stuck in a tree.
Lastly – 4th pic down of the two clamps either side of the branch – you’ve just drilled 2 holes straight through that and created a massive weak spot, right over the trampoline. That is an accident waiting to happen – it will fail.
Sorry – don’t want to ruin your work but I’d go back to the drawing board.
Sorry again!!
