What causes a tree to barber chair

[TheJollyLogger]

That will help with twisting and fiber pull out but won't do a thing to prevent chairing.

Gotta love terminology... We were taught that holding wood is the small section of the trunk opposite of the hinge. I have also seen it referred to as a "strap" and "strap cutting".

I did a quick search and found this OSHA web site that some might find useful...

https://www.osha.gov/SLTC/etools/logging/index.html

It shows the technique that I mentioned MINUS the Open-Face notch. I can't understand why Open-Face has not gained more popularity since it is ABSOLUTELY safer - the tree remains attached to the stump ALL the way to the ground. I guess that it may be the small amount of salable lost timber to the notch but how much is a life worth?

I just hope that the OP figures this out before he gets seriously injured or worse yet - killed. If you are making Barber Chairs (consistently like the OP apparently was doing) you are doing something WRONG and need to improve your technique.

I have been using the open face notch, and conventional. I dont have any knock on the homboldt, and will begin to try it. I see some advantages to it......and I learned alot from the series here.
I was searching around about Leaning tree's and found this thread and found it interesting. I have not experienced a Barber chair, and I am thankful.

the triangle is illustrated here.....

The open face cut is listed as safest by OSHA. https://www.osha.gov/SLTC/etools/logging/manual/felling/cuts/notches.html

Yeah, this thread got a little derailed. Keep in mind, the type of face cut has nothing to do with preventing a chair. Preventing a chair is all about assessment and what you do on the backcut.

I know this is an old thread, but I just came across this while wandering around and thought it should be addressed. A quick perusal of barberchair videos online will show that many of them start when the face closes if the hinge is too strong to break. So, more open face, and thinner hinge help prevent a ‘chair.
