Two good thought-provoking points from readers about my tree-house construction.

1. The Y-supports at the sides. That’s some length of beam (around 9 ft.)

to be doing vertical support. Watch out for warping and bending.

2. The south support of the first north-south beam resting free & sliding

in the secondary crotch. This is going to wear away at the crotch as the

tree shifts. Needs some reinforcement.

Neither is critical, but both need further thought.
