Bart,
Thanks for the clarification. I would agree with Reach’s assessment that the tips hit first, unless the cut was over the roof!
Evo got it with a conventional face or a humbolt. My preference would be a conventional or slightly narrower with a snipe. I always end up with bypass on...
Mr. Beranek has simply the most comprehensive instructions on this to include all the factors to consider.
I find his “Ratio Factors”. Pg 221 The Fundamentals of General Tree Work to be the most useful factor for what you are describing.

Have worked in a commercial orchards, the bulk of pruning was to create a structure to bear the fruit (weight) and get sunlight and applied pesticides to the fruit. (crown reduction and thinning)
In my experience (east coast U. S. ) the great majority of apple varieties only produce fruit on...
You have a point. It is easy to take just the bits, that fit your current schema and apply them poorly to a bigger concept.
So, to summarize.
As for the 1/3rd guideline, it falls short mostly in that not all trees are round. Depending on intended direct of fall, “1/3” may create very...
No worries, I am not suggesting you or I would take any unnecessary risk, nor ignore any of the other factors that come into play with accurate felling.
I see this as a discussion and exchange of ideas, thoughts and experience. I hope some are finding value in the discussio.
Given your...
I agree with all you say. I may be splitting hairs, but it seems to me in your apt description it is less a factor of hinge depth and more a matter of back-cut speed. Well actually how quickly a hinge that can bend is formed. This of course assumes you have a face cut with an apex that forms...
Ahhh…
In that case may I recommend a poem
A sort of literary first aid!

Think gently of the erring:
Ye know not of the power
With which the dark temptation came
In some unguarded hour.
Ye may not know how earnestly
They struggled, or how well,
Until the hour of weakness...
Did they send you a notice? No reply is considered permission. A reply shifts responsibly to the property owner.
pretty sure you can handle the work.
No notice means they are claiming eminent domain. Fairly rare in a residential setting.

I am glad you understand the concept well enough to realize when you choose to ignore it!
We always called that testosterone poisoing and many years ago it led me to fall out of planes, train to be hard to find and harder to kill, walk towards fights that were not mine, and try to save the...
I think it is less a matter of increased barbers’ chair possibly and more a matter of shallow face cuts allow for less hinge length (all things being equal) and thus inhibit the face cut and back cut from working together to form a reliable hinge.
The tree diameter does not change, but a...
Evo,
You missed my point. Saying “why not” is entirely different than asking “why not” of a tool/technique.
As Oceans implied, it makes one look to limitations as well as capabilities.
Tony
Phil,
As a long time trainer, I have found the more valuable question is “why not?” Understanding “why” certainly is important as it gives validity to the “how” of a task. However, ”why” questions really, in the end, only address methods.
Asking “why not” questions, forces one into...
The best reason to forgo any depth ratio like 1/3 and choose instead a hinge length ratio, like many have said, is trees are not always perfectly round. A hinge length ration compensates for this
Tony
Many times I would use a double whip to do the stem of a large limb, simply becase the second block ( the one on the piece) was already there as I had rigged the brush off with it. It was the most time efficient way to get the block to the ground
Tony
300lb has always been my limit for a well set up speedline. Seems a safe estimate. In the field though I would be very conservative with my weight estimate so I probably stay much lower.
When in doubt I will negative rig, then use the GRCS to raise the piece back up, then connect to the...
I cannot speak To why the evo is set up that way. I do know in my on going experiment with a second bridge, linking them together keeps the unused one from flopping around.
