Thank you for being so detailed with how you did it. I'm wanting to do something similar on my land. Your setup and land looks like a fantastic place! If only I were on the East coast, I'd come and take some classes from you.
Hi Pat. People will often put a cable around the tree trunk and that works well for a temporary set up. Anytime you have a cable around the tree, even if you use spacer blocks to protect the tree, you could end up with the cable cutting into the bark of the trunk and damaging the tree. With a through bolt installation the tree can heal the relatively small wound of the drill hole and continue to grow in girth unaffected by the zip line cable.
Not that it’s a major issue but it’s interesting how the screw gate turns and opens during the ride, and the screws down again.. The con of screw gate carbiners..
it seems like the weight of the line will start pulling the tree over. This does not seem like a healthy rig for the tree. Why not use a strong post that has two or more steel cables anchoring it to the ground?
You should never be hitting your stop block- either move your bungee brakes or get a Spring brake or both. Your 160 lbs won't hit it but a 225 lb probably will. And the throw line attached to your bungee is unnecessary and potentially dangerous. Just move your bungees out of the way by attaching them somewhere else. Otherwise cool setup, thx for sharing.
