Sizwheel, this is how i understand it.

- Sizwheel style undercut is used to control a hard leaning tree. The fibers on the tension side were supposed to tear away from the backside of the stump rather than breaking.
Stihl MS461 with 28" bar.
Rakers were taken down to far with my first 2 in 1 file guide. She was way to hungry in this video!!!
I love the honest assessment. So much learning! I noticed the Dutchmen right away, but thought it might work out anyway with that crazy notch! Nice 👍
good explanation on this. i've seen it done but have never been walked through the mechanics of the cut. it's a good one to know in case a guy needs it someday. keep the vids coming. thanks
Great explanation! Seems the face cut is a bit too deep IMO. Also that saw seems to be struggling… may need a bark box or a M-tronic reset? My 400c would bust that out no problem 😎
Great video! Interesting technique.
I wish I could have been there to see that .stay safe
yeah it was fun. i have another tree i want to try it on. it has a harder lean so i beleive it will work correctly.
Kyler Monares yes logger wade offers a lot but if only I could hear what he is saying (strong accent ) and better caméra work would help us all . we all need advice
I don't see the purpose of the chunk cut away. seems to me the big thing is the wedge shaped hinge. the thick back of it is against the lean and stops the lean taking control so the tree falls 'sideways' - i.e. the way you want it to - under the influence of that much of the centre of gravity that is on that side. the influence of the centre of gravity that is 'forward' - i.e. on the lean side - is counteracted, 'stopped', by the thick wedge shaped hinge, the thick bit being, as said, at the 'back' of the lean, the tension side.
So that being the case where's the usefulness of the chunk cut away?
I dont know if this helps or not, but using the sizwheel/siswheel on hard up hill leaning trees could lead to a bad barber chair. Hard leaners are best with a bore cut. Stay safe
In the scenario of the video,barber chair is very unlikely as the cuts were 90 degree to the lean,hinge ripping out with the weight is more likely, but a bore cut when felling with the weight certainly
@@silverbullag4759 Agreed!
Seems like the rakers are a bit too deep
That's what I was thinking. I also believe that saw is not tuned up to max rpm. May not need to be but it did sound as if it could have delivered more RPM at times....
Hi Kyler, just checking out some of your videos! Keep em coming :) Be safe!
an (additional) scarf cut on the lower part of the face cut might allow more free fall before the face cut closes, so that the holding wood holds for a slightly longer time.
Just a tip losen that chain up quite a bit. Saws having a hard time pulling it and you'll burn up bars like nobody's business
You can hear it rubbing the bar
good job, just a bit of advice... when trying this the wide part of the face, I.E. the hold side, needs to be one smooth surface, avoid nicking and gouging it, it will pretty much always fail at a nick or gouge, secondly try if you can to use a root swell as the hold side, gives maximum fiber. stay safe.
northman logging awsome advice thanks!!! I'm going to upload a part 2 to this video. Got another tree I am going to try the technique on. Hopefully it works this time!
its one of those tricks that when it works its slick, but I wouldn't count on it in a high risk situation. Its half science half magick
Advice; score the tree lightly ( bark deep) around your undercut to see if your cuts line up before committing to the cut. Ajust as needed.
Hello. Nice video. And clearly by the technique you are influenced by 'Tarzan. He's a great faller at his age. Now the technique. I saw that you didnt match the siz-cut with your humbolt. Then your fibres doesnt do what you like. I like to clear the bark just to see my cut better. On these trees there are thick bark on it. Thats my thought.... I'm not that a good faller my self but I do get my trees where I want. Have a good day ;)
MTM Skogservice AS Yeah maybe the first vertical cut of the Siz not matching the felling cut had something to do with the fibers not tearing away. I'm thinking more that the tree wasent leaning hard enough for it to work. There's another tree with a harder lean that I'm gonna try it on. I'll clear the bark away so I can match my cuts up perfect. I have a really hard time with the humbolt. Just need more practice. And a chain that isn't to hungry!!!!
with the humboldt do you first cut like you were but were you come up keep the bar at the same angle but just point the nose down. i learned that from the guy up in bc. cant remember his channel name. been doing my humboldts perfect ever since
ian martin I'll have to try it out. I get what your saying! Thanks for the tip!!!
Good job man but your notch should only be 1/3 of the tree. Be safe
Late to the party but I have watched a few videos on this technique & it seems that a smaller side cut gets better results. What have you learned in the last four years?
Great demo video, sounds like you took a little to much off the rakers and it's stalling the chain. If that's the problem. I hate it when I'm cutting and I have to fight with the saw. One of my pet peeves cuz its my own fault. Thanks for making the vid.
I was shocked to see that you have not accomplished a proper face cut, and are attempting a more advanced technique.
Just so we're on the same page, or chapter at least, can you tell ushow a "face cut" became an "undercut" and how the "hinge" became "holding wood"? (Yes, I understand that the guys up in BC butcher Funk & Wagnalls that way- not an excuse.) Eschew fuzzy thinking. :')
Kyler check out big bear tools if you are looking for an Arvika.. Hope that helps
Larry Duttry thank!
No problem! Don't buy them all up because I want one too!!! :)
I wish to Know how much you paid for the 880 I live in Canada I wish to compare privés thanks
Luc Fournier about $1700. Powerhead. 42" bar, 2 chains
That face-cut was Ugly! Exactly how I do em when I try for that humboldt cut.... I have ended up with the face cut so deep after 'cleaning it up' that I'm amazed the tree is still standing on it's own. I just keep on practicing and sticking to my masters studies at RUclips University.
I ment prices 😃
chasing your cut on humbolt 😂I have the same problem
I ve watch this vid5times it was good practice in a open field but with heavy foliage and a450.000.00$house next to it I would have done different .I love to expériment when there is no hazard ne ar by keep up🙋
Luc Fournier yeah this is definately something that needs to be practiced. Most of it is identifying which trees it will work on and how to execute it in different situations.
Kyler Monares loggerwade as some good stuff to look àt as well
Luc Fournier I have been watching Logger wades stuff for a while now. Pretty neat content he puts up. My favorite is Tarzan Thomas
Sizsizwheel doesnt work
i don't like your cutting...the engine is overload !!!

Kyler Monares the 2 in 1 doesn't work on any skip chain...learned this after having the same issues
😏 Lange niemand gesehen der so wenig Ahnung von Baumfällung hat. Säge läuft nicht richtig, falsche Einstellung? Schwert vielleicht doch zu lang? Leistung der Säge nicht ausreichend für die Schwertlänge. Fallkerb viel zu tief und nachgesägt! Keine Profi Arbeit. Ich hoffe, Du verletzt Dich nicht, bei dem was Du da tust.
