Ekka:
You're the one that has changed.
We didn't see you bore through the hinge because you didn't understand that was an option. No big deal, you hadn't figured out that a quarter cut technique is generally secondary to the basic back cut before a face cut otherwise you would have listed it.
Here you again, so now not only have I have changed something but I dont understand something!
You must have auditioned for the movie Dumb and Dumber! :monkey:
Stop and think readers, be very careful. This is a public forum, and from chaff cutters to firemen they all get a chance to write.
See, Ole Smoke and Mirrors has changed a cut or procedure and then feels he can run others into the ground, assumes they are stupid or telling lies.
But that is because ole Smoke and Mirrors has self elevated his rank within his own head.
He'll move the goal posts around to suit himself as neccessary to accomodate his ideas, and then strangely even attack and put others down.
Shortly I will be an official trainer, not only assessing peoples felling skills but also seeing what they know or are capable of if things go wrong.
In the event that you do the 1/4 cut which is designed for small trees, it's clear that all the hinge is best. The problem with small trees is you cannot get a bar width and a wedge behind it into the tree, the tree is simply too small a dia to do that.
Some solutions which work great are stacking wedges so there's more taper. That's a great idea for people like Smoke and Mirrors who seem to only have one size fits all wedges in their kit.
I have an assortment, but genuinely love the aluminium high ramped wedges, I even use them on the big trees and you can really lay into them with a maul if need be.
Now imagine yourself in a situation where you thought the tree would go over and belted the wedge in, the wedge is now butted up against the hinge wood but the tree isn't going. What would you do?
Well, who says you only have one wedge in? You can wedge the other side of the 1/4 cut (or any cut frankly) too, but you now have a large gap there due to the first wedge in, so you start with a double stack or high ramped wedge. Soon as this new wedge is lifting the other wedges can be pulled out and also stacked ....
Whether this is with the 1/4 cut technique or any other technique what if the tree "sits back" on your saw? So again, you can bore cut and wedge.
These solutions aren't just solutions to one technique (as Smoke and Mirrors suggests) nor does it make the 1/4 cut technique defective. And as you can see solutions abound, so what Smoke and Mirrors has suggested is a solution to a problem that might occur (in more than one example/technique), and it's just one solution, there are other solutions like felling bars/levers, roping and even a pole like some-one suggested.
Thin trees can also be tall trees. Tall thin trees do get pushed around by the slightest breezes. Palms fall into these categories and I have 1/4 cut thousands, like a production line, never ever had a wedge shoot out, never ever had to bore my way out of a jam either. If for whatever reason extra support is required then rope it, clear and simple, but as far as fast production you wont beat that technique. Slash pines abound around here too, often they average maybe 12" dia but are up to 80' tall. When I get these, or any tree compared to a palm, it's better. The wood is better and things are a lot more stable/reliable. Pines hang on great, very flexible too. In most of my videos you'll see me using high ramped aluminium wedges, ever seen one shoot out? Nope. Eucalypts here, often the Ht to DBH ratio is around 45:1, that means a 1' dia tree is 45' tall and 2' dia tree 90' tall. Heavy timber, the high ramped wedges are great here too, with the shallower wedges I found I belted them in till they were flush, simply not enough height on them for the lift, that is the conditions here, we're semi tropical and many trees grow tall for DBH, they grow nearly all year around.
And even if Smoke and Mirrors or Clarence is not allowed to use one, refuses to use one etc who gives a **** really, fact is I can and do, lucky me I guess while they miss out.
Knowing various techniques is wise. Knowing how to come unstuck for any technique is also wise.
And in summary, there's no caveats, just common sense and procedures for getting out of a jam in many felling techniques.
