    vertical speedline size/weight limits

    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.

    vertical speedline size/weight limits

    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...

    Mystery problem cutting?

    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...

    Nerd Alert

    @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...

    Sounds to me like you need a new bar.

    vertical speedline size/weight limits

    Doing the top first on conifers is the way to go, when possible. Mass damping makes such a big difference. I like mid-tying the pieces, it allows the speed line to exert pull on the piece to help it come over. Drawback is that it puts extra slack into each rig, depending on the distance between...

    Break test on a climbing line that has been “spiked”

    Whenever this happens to me I just stop what I'm doing, grab the line about a foot on either side of where it got spiked, and give it a few good "pops". This almost always fixes any strands that got yanked. I generally don't worry about damage/cutting of internal strands. The sides of my gaffs...

    Catastrophic root failure

    This butternut tree was fully live, with a severely compromised root system. The owners had no idea it was in bad shape. It fell over in a mild wind storm. Trees like this are the reason why site inspection is so critical before climbing and rigging in trees. Our only explanation for why the...

    Songs of Perfection

    Best version of the classic tune by Eric Johnson that I've found, stripped down to the basics. Fantastic.

    Rope grab recommendations for rigging

    I've had a prusik slip multiple times from guys pulling on fiddle blocks attached to pull lines. The prusik melts to the line, they end up welded together. That would be a fun test with a load cell, see how much pull it takes to do that.

    Today....

    Good help is hard to find. I'm going to keep this bar for cutting logs with big spike nails in them. Hoping it will just sneak right around them...

    Doesn't every single tree guy own a homemade knockoff portawrap-looking-thing, made by themselves or their brother-in-law? That could be its own thread ...
