    Best facecut for negative rigging?

    And then cross over it back and forth a few times until your head is spinning and you can't find the door...

    Best facecut for negative rigging?

    I suck at cutting a humboldt from the ground, but make them work when taking out tops ... They are crucial for jumping tops and keeping a top that might hang up on other trees from coming back over the cut... Those cuts if made today would be close, probably same narrow humboldts, just...

    Best facecut for negative rigging?

    Anyone that's had a top hit another tree/limb, slide back over the cut and land in their lap will quickly learn the value of a humboldt when taking out tops.. If it looks lie the top is going to hang up, I cut the humboldt narrow and super steep (facing almost straight down), then push the...

    Best facecut for negative rigging?

    Does anyone know for sure if a Humboldt causes less fiber-pull??? I would guess so, but hardly ever use one so don;t have enough experience to know for sure..

    Best facecut for negative rigging?

    the inclined plane of the top cut on traditional causes the stick to want to slide right back off the stump, where the inclined plane on the humboldt causes the top to want to slide down and forward.. that's clearly going to make a difference in the forces at the stump/cut... so some of the...

    Best facecut for negative rigging?

    Maybe .. just maybe the humboldt puts all the force on the hinge at once and causes it to pop, where the traditional starts ripping the fibers apart from back to front, which takes a bit more time.. FASCINATING!

    Best facecut for negative rigging?

    I've studied slow motion video in some detail and feel pretty secure in saying that the Humboldt separates much faster then the traditional... Hinge breaks faster. I haven't figured out exactly how the physics works, but it makes sense that the humboldt would pry the hinge up more than a...

    Best facecut for negative rigging?

    with an open face the main force of the top is going down, rather than out when the notch closes and the hinge starts to break.... That seems to reduce the spring effect, however you have to be careful that there is nothing on the ground behind the tree, as the tips can hit close to the trunk...

    Best facecut for negative rigging?

    another way of looking at it is what is the worst notch for taking tops, and negative rigging long pieces. This would only be much of a concern before the wood gets thick, and you are chinking pieces.. The 45 degrees notch or traditional notch will tend to cause a lot more spring back...
