I feel that. I was about an inch away from running over my 575 with a truck when someone yelled 'stop!'. I actually hesitated to stop because I thought he was just being dramatic or something. Glad I listened.
Yeah it was fun to climb on. I always liked the feel of 5/8" on the hands. Definitely heavy. And the lack of a heat resistant 1/2" hitchcord and compatible ascenders made it... tedious. I used to just footlock up and slide the hitch up as I went. I made a thread about that system way back then...
That's actually a 'true blue' hitch on 5/8" static line, if you can believe it. Functions in SRT without a wrench or anything. Climbed all that summer on that system..
The guy I learned from, Nate, who learned it from the Englishman, Andy, both did it the same way. Free climb on spikes to the tie in point, then lanyard in, then tie-in. Nate was 19 when I started there, I was 27. He would free climb anything, over 60 ft, before using a lanyard and tying in...
Thanks for sharing Steve. Hard to tell the structure from the pictures but it looks like the rigging created a lever arm? I can't recognize the species from those pics. Could have been so much worse eh, glad you're ok.
I would argue that that is why more don't get it, because it has been watered down to the point of uselessness. The CA program is a racket, and tree guys see through it. In the extremely rare case that a customer ever asks me if I'm ISA certified, I just smile and say, "well, I used to be". I...
It is definitely very violent. I've broken a good sling doing it.
I like the setup that Reg used in this one, with the tires and the extra strap on the rope above the lowering device. Every piece double-slinged. Slow down the video and analyze the collisions when the pieces hit the ground.
To me, mass damping is good practice on all trees - significantly reduces stem wobble, increases safety factor by mitigating effects of shock loads in negative rigging. I have really tried to make it a habit over the past few years. On hardwoods, when it makes sense, I try to leave 2 or 3 good...
The bar can get tweaked sideways just enough from hard usage that it won't run true. You won't notice it by eye just looking along the length, it will look fine. Easiest fix for the behavior you're describing is a new bar. I cut lots of poplar, there's nothing about it that makes it bind like...
@Bart_ I realized another factor with pulley efficiency many years ago when setting up a climber zipline, and that is, small diameter sheaves are unable to rotate freely at high speed without "jittering". I set up a zipline at a golf course during our apprenticeship training. The rope ran from...
