Problem: The drill hole of the GTS screw in the tree is a little too high or too low.
If the drill hole is just a little too deep or high, but the horizontal alignment is correct, this is not a big deal. Usually the height of the wooden beams, the platform, the other screws or stilts can be easily adjusted. If your GTS screw is a little too high in the tree, mill away part of the beam (be careful not to weaken the beam too much!). If your GTS screw is too low in the tree, raise the beam by placing a wooden wedge under it.
Problem: GTS screw mounted in the wrong place in the tree or drilled crookedly
If you were asleep or drunk during installation and the wrong / crooked GTS screw is already in the tree, leave it in: an open, deep wound would be bad for the tree, as fungal spores and insects could get in. The best thing to do is to flex off the protruding screw on the cylinder so that the tree can cover it better. Then weigh up whether the tree can take a new GTS screw … if you have any doubts, it is better to continue building with a Cable Suspension or on stilts.
