Ah, thanks Joel. It's all pretty deep a subject. I generally stop where you have to be good at math. :D

Yes, I know it was just a theory, and in the same spirit for discussion purposes, I was just saying that the empirical evidence by way of testing in the laboratory doesn't support it. Dan, you can correct me if I am wrong, but although there is a pretty good list of qualities that comprise what...

Studies of variations in tissue structures in trees and the mechanical properties that result, would seem to conflict with your theory, Daniel. You are right in thinking that reaction wood (compression or tension) structure is different from normal wood that is in greater equilibrium, and that...

Stig gives a vague response, and I believe it is also the most authoritative one. Within a given species, it is known that there is a direct correlation between elasticity/bending strength and wood density. Denser wood has stronger physical properties, as in bending a greater amount before...

People sometimes seem to forget that trees are actually made from wood! I know a number of my customers do. :roll: Scientists have pretty much determined how wood with species and moisture content variations are going to respond to different stresses up to the point of breaking. A six inch...

We do have at least one person that worked as both a logger and a commercial fisherman, and somewhat miraculously he is still alive.

A good joke should get at least one comment. :lol:

Perhaps along the lines of what Patrick says, isn't a distinct difference between the step cut and a standard face and back cut when pulling trees, that with the standard cut where you cut a little and pull a little more, that you have the hinge holding the tree and yielding in progression as...

Al, you make a plausible argument.

I was thinking about this divergence of opinion about methods. Dan shows he can handle a large saw on spikes and seems to have a lot of confidence about his approaches, I don't doubt that there is a lot of experience in the field behind it all. Burnham, if I might take the liberty of...

I apologize, if my post is interpreted as being ugly. Perhaps it asks too much to think that I have enough posts up on the board to assume that my way of sometimes communicating will be regarded in the vein of being satirical, than appearing to seem critical to the extent of unpleasantness. I...

What the hell? Tom Fool? Anyone can get creative if they don't mind dangerous, or in the very least messy as all get up. It must be a cutting technique for paraplegics wanting to get out of there, or ones that have suffered enough.

Murph, I'm interpreting that one cut in the earlier #72 post vid as your "jump cut", where the small face closes and the tree jumps from that point? Having just wondered before what you were referring to?

Given that someone has familiarity with the technique, as Murph does, and knowing how wood responds to certain stressea that cause breakage, I can't see why the step cut should be considered insufficiently safe or unpredictable. There are grain or species variables where I would think it could...

Chris, with a heavily leaning tree, I think it generally gets referred to as a "trip" cut, and often not so much wood left to make a proper step. More just releasing the holding wood from below the level of the bore, to keep your saw from getting caught within the splitting wood. The times I...

A straight grained species like Black Acacia or any other wood that splits easily, I think supports that technique. Something like elm or Zelkova, maybe Sycamore, where the grain 'knits' together and the path of least resistance where the wood wants to split may not be along the grain, it seems...

I can't see why you guys are so adamant about that method in general being a hard pull to get the tree over. Maybe it was in the video how it was done, but I can think of a number of different ways to lessen the remaining wood in the step there to make the tree go over easy enough and still...

Scott's use for the method seemed like a wise one to me, pulling a top after climbing down. On the ground, having a lesser step I believe is going to reduce the amount of pull required, and also reduce the chance of unfavorable runout that could adversely affect the hinge. If the point is...

Aren't there better ways to do the same thing, tailor the back cut so that you can get out of there and not have a concern about possibly compromising the hinge? It would seem to possibly require some finer cutting to get the results hoped for.
