Excellent advice Steve.
Would it be better to use an appropriate through bolt/nut to ensure that it
does not come off
over time.?
Would the tree need any kind of treatment just to prevent soft wood like pine
rotting
in a few years due to the wound.
Once the tree is topped, how do you get to the top to rig the rotor/beam? Do
you use a crane
with a bucket.? Sounds really adventurous as compared to climbing towers. :)
