I've been using a stepped back cut for over 30 years to fell trees and take tops, plus several variations. It's only been recently I've had to relearn a new method of felling trees.
I now always have my back cut as level possible with my face cut. After a 70 degree face cut I plunge cut my back...
How about those steel pipes homeowners hammer in next to newly planted trees to "deep water the roots". 30 years later you have three ft. of cut resistant trunk. Takes destroying several chain before figuring it out.
We've used foam before, but I believe it's best not to add anything. It just traps moisture and offers a convenient place for bugs to thrive.
Another common out dated practice was drilling and putting in a drain pipe on hollow trees.
I'm going to one up them yet. I'm teaching my 2ed climber to srt. He's a willing, quick learner. I think i can come up on my own several ways to cover different scenarios of potential rescues situations that can happen on srt.
I feel I'm hitting a block wall trying to have N.A.T.S certifie me...
Yes a Basel based tie in is required. They still require the other climber be fully competent so he understands the system, and could retrieve you if you were dead weight on your system. I not sure know the proper protocol for that kind of rescue. But could figure out something.
Problem I'm having getting gunapproved to use SRT besides their equipment specific requirements, is as they say,"you can't out climb your rescue climber".
I've been using the RADs system for years. I can meet their guidelines, but in order for me to climb srt, so must my other climber. My other...
The prime contractor on our job requires we climb with both a lanyard and a choked friction saver around the tree at all times. The reason being that at any time we could descend immediately.
Not two lines or some type of choked line but a friction saver. On smaller trees, less then 40 dbh it's...
