Problem: Hole drilled slightly too high or too deep If the borehole is just a little too deep or high, but the horizontal alignment is correct, this is not too bad. Usually the height of the wooden beams, the platform, the other screws or stilts can be easily adjusted. Mill away a part of the beam or put a wooden wedge underneath. Make sure that the carrier beam is not too much weakened! Problem: Screw set completely wrong or drilled crooked If you slept during the assembly or were drunk and the squeaky screw is already in the tree, then leave it screwed in in any case: an open, deep wound would be bad for the tree, because fungal spores and insects could penetrate. It is best to flex the protruding screw on the cylinder so that the tree can overcome it better. Weigh then whether the tree can stand a new screw… if you have any doubts, continue building with rope suspension or on stilts.
