experiment with spars once they are too short to hit anything, in the meantime. I can understand the concern, but they're more elastic than you think, species specific, though. Learn to ID each tree, then catalogue the experience in your mind. Ask about species specifics. Mostly, to start find...

I don't know about that. I wouldn't suggest banging over a back-leaner that hangs over the house. The wedge, just like a pull line, gets the tree to commit to the hinge. The hinge does the direction. If you can't figure out how to cut a solid hinge, don't fell trees/ spars in striking distance...

Agreed.

As a note, moving the hinge to the rear reduces wedge leverage on the tree. It exerts more upward force on the hinge, possibly leading to tearing the hinge. I'll move the hinge back, and still wedge easier to lift trees, while being aware of this. A hard to tip tree, or back-leaning tree...

You're on the right track, Chris. I was the same way about tree climbing and rigging. I came with the rock climbing/ basic rescue rigging background. Read, ask, and try. Read, ask and try stuff. A dead hinge will be less flexible. The full blockout/ gap face helps to make a tall hinge...

I'd love to have someone serious and motivated as an apprentice, who I could hope to keep, or send out of town. Are there apprenticeships? Its not like being an apprentice electrician.

Working with the lean is going to change that compared to having to work against the lean, or 90 degrees to the lean. Seems like apprenticeship would do well for the industry.

It bet it would be informative, Daniel, if you can get the chance some way or another.

We got good at shoulder/ head high humboldts with big saws because there can be more solid wood up there when dealing with root disease, as par for course.

That probably works better in some situations, but... Have your traditional, tried and true hinges been untrue? I've beat over so many rotten trees with a percentage hinge and wedges. Somehow it always seems to work. Does root flare help fight highly barberchair prone trees splitting?

I can't figure out how a 3" hinge works trees unless you're relying on a machine to compensate for the wrong hinge.. A 3' and a 6" and 6" tree don't all use a similar hinge. A rotten tree and a solid green tree don't use the same amount of hinge. A cottonwood and an oak don't either. I think...

I don't always have a bathroom stain on my pants, but when I do, its at Walmart.

:lol:

Being easy on the cat doesn't count :). When you have a cat and a cable stronger than the tree, a tree like that doesn't need a face, just put your foot down. :lol: Just kidding. Only pretension a little, so the tree is still sorta at rest. Not sitting down on your back-cut, nor opening...

I, too, thought about a full block face. In that size tree, I'd blow it out with the ax. Beware strong spiral grain with a gap-face (not an issue here). Boring the vertical portion that establishes the front of the hinge, will hide discontinuity of grain compared to busting it out. If you have...

4" hinge is probably too much to be flexible and do an actual hinging action, Probably took quite a hard pull, unless they are decayed. Are they solid, green trees? 25% of the diameter for the hinge thickness is a lot. Too thick of a hinge will induce a split, too. We were pulling a 120'+...

Absolutely face-cut the ones you will pull over. Chain those. Put the binder on the underside, so the log doesn't flop onto it. Chaining a good safety measure. Easy if you're doing residential. Beware side lean. Jed, I figured he's maybe near us. I don't know what people figure to be PNW. I...

I agree with all the above. In Jerry's FOTG it stipulates to use a Sharp and powerful saw, so worth repeating. It was suggested to me not to cut with the lean, but off to the side of it. I guess it is to effectively reduce the loading directly along the neutral plane. Where are you...
