    Getting a tree to drift during fall by thinning the hinge.

    Or there are other variables contributing to a perceived drift and we just anecdotally attribute it to our cutting. Slight wind, for example, on a 200' tree could move the top a dozen or more feet. Also the sail effect as a tree falls and it's branches catch wind. That effect could push the top...

    Getting a tree to drift during fall by thinning the hinge.

    I have not. Which is one of the reasons I like watching guys like August and Reg. Most of the concepts and techniques I see I am familiar with. the fact they are cutting in a different region, with different trees and their characteristics is where I find the opportunity to grow beyond my local...

    Getting a tree to drift during fall by thinning the hinge.

    Lol ... A younger me might entertain this notion. The current me, not so much. It is an interesting point to identify the cutting speeds between cross cuts and chainsaws as a divider in learning felling cut nuance.

    Getting a tree to drift during fall by thinning the hinge.

    This I 100% agree with and understand. I have done this may times to utilize the momentum of the falling tree to roll off another when I was expecting crown interference. I would usually cut through the desired hinge corner before the tree started falling though, not while it was mid fall, and...

    Getting a tree to drift during fall by thinning the hinge.

    August Hunicke posted a new video to the YouTube. Pretty short video and he gave a pretty thorough educational style explanation why he was doing and making the choices he was. I usually agree with pretty much everything he says and just passively watch guys like him and Reg, enjoy the...

But it is undoubtedly more expensive to design each individual to withstand the most unlikely loads. The natural ballance is therefore...

    Placing outrigger from aerial lift on a raised curb for operation.

    Same. If there was a height difference between the curb top and soil, I would put cribbing on the soil to make even with curb. This was usually a small difference if any.

    Placing outrigger from aerial lift on a raised curb for operation.

    Scenario: You are going to work off the passenger side of your aerial lift truck. You are close to a curb and when the outrigger is lowered, it rests on the outrigger pad which is placed on curb itself. The outrigger and pad are centered on the curb and the curb concrete is in good condition...

    10. "When a reparative symptom is found, the only assumption that can be made is that the tree has a defect which it is attempting to counter by means of adaptive growth. On no account must every tree bearing symptoms be felled! In the human sphere this would mean dispensing with all medical...

    Use of RRP without EN 1891 A lines

    Is it generally allowed in comps to use the rope runner pro without en1891 type a specific lines? I use 11.7 double braids like blue moon and hyper climb, but the manual for RRP says to use en1891 A ropes.

    7. "In an unpruned, healthy tree the relative area of the crown, stem cross-section, and the root plate will be perfectly matched to the wind load as 'measured' by the tree. It would be life-threateningly extravagant for the tree to treat itself to an impressively thick trunk beyond the needs...
