Hey all,
I selected a "test" tree on my property for cutting. It is about a 100 year old Oak. I knew it would hang up so I attached a 100' long rope to the top of the tree. After cutting I pulled it down with my tractor. Landed just right. Had a nice "hinge" for the falling. Problem #1: The tree sheared right up the middle of trunk about 3 feet effectively making it too short for a post. I believe this occurred because of pulling it with the tractor creating a lot of compression on one side and tension on the other. My cutting notch needs to be > shaped next time instead of _\ which I think will relieve the compression pressure. Problem #2: I felt a lot of grief after cutting down the tree and found that I had to shut myself down emotionally in order to get it done. I don't have a solution for this problem except that we are renewing our search for salvage lumber. There is just something about Oak. I don't think I would have trouble cutting down pine or fir which grows like weeds around here...

Problem 2: might be better discussed in a different forum, but I'll put on my Carl Jung hat and say that the grief you feel is due to the fact that you have personified this tree, and when coupled with Problem #1 there is a sympathetic relationship between you and the tree described by "hurt". Perhaps you feel this way because the tree has no job in its current state; make use of it and you will feel better.

And/or plant an oak tree when you take one down. If you build right out of the one that was taken down, then the new sapling should be as big as the one you took down before your building goes back to the earth.

Or you could do rammed earth.

Why not Pine or Fir in the first place since you feelings are not as strong about them?

It seems your oak almost BARBER CHAIRED, one of the most dangerous felling conditions. Since you are WA, where the forestry industry is large, get training. Ask about "The Game of Logging" or try ag extension agents, state occupational safety adm, adult education services, etc. Logging is one of most risky industries in the nation. A day in the woods with a chainsaw can rapidly progress from an outing to an adventure to an ordeal. Also check out the Forestry Forum. Be safe.

Hi Paul;

Professional chain saw training in maine now involves a method of cutting where you make a notch and then plung your saw through the tree being sure to not to cut the hinge. Then, the last part you cut is the farthest point from the notched side. This, they say, is the safest method of cutting.

I do not know what this method is called. I looked quickly online but nothing came up. I thought there might be a video showing what I am talking about.

One of the advantages of this method is you will not get the middle of the log torn out, if that is what you mean by "the tree sheared up the middle".

I saw this demonstrated at the best fair in Maine,, the Common Ground Fair, if that helps you track down more information on this method of felling.

Felling a tree for lumber is like butchering an animal to eat. Everyone should experience it to appreciate what they have and understand what goes into making a 2x4 or hot dog.

Many woodworkers justify the murder of inocent trees in that they will "live" on for possibly hundreds of years as someone's material possession. Firewood does not add to global warming, it is a cycling of the carbon unlike reintroducing captured carbon from underground oil wells.

O.K., I am getting off my soapbox now.

When I was just a young pup, I had an ash tree barber chair on me, it could have taken my head off. A quick lesson, it was. I have never had one do it since. You had too much hinge left

Plunge cutting as Jim described works well, plunging the saw takes some practice and something I am not going to go into, find someone local to show you how it is done. I would even venture a video wouldn't do it justice. It is safe and allows you to insert wedges to keep the tree from pinching the bar, or back the skidder up to, and give the tree to give it a push, while you still have two points attached.

I would encourage you to keep at it and mix the species too. I know the feeling, I have shot a number of animals hunting and trapping. The hardest time I had to pull the trigger was on a goat we had, the first one we had for slaughter. Trees are not much different.

Paul, it is not all just drawing pictures and calculating, you have started from scratch, it isn't a cake mix where you just add an egg. Adding the egg does take you into the other forum Mo mentioned, studies have been done.

Jim, I'm pretty sure it's called "hinge and latch", with the latch being the last cut you mention that 'unlatches' the stem.

We just call it a bore cut around here. I use it on heavy head leaners. I don't use it as a rule, it's just part of the bag of tricks you need as a logger.

I'd like to first recommend that you find someone to give you some advice first hand, if you can. As for books, the best I can recommend is G.F. Beraneks "The Fundamentals of General Treework", available at www.atreestory.com.

I was taught that as a "bore cut". This is the OSHA logging site;

Here is a video of the "bore cut":

Here is another video showing an interesting technique for directional felling, and possibly could be adapted into a new way to cut tenons?

Thank you all for your informative and understanding replies. I will do more research on cutting. I have spent a lot of time in the woods bringing down trees and have never had this happen before (the barber chair). I belive it had to do with having to pull the tree over with my tractor since that is the only new variable in my experience. I cut towards the notch right up until the tree was starting to fall. At that point I always head for cover. In other words, I don't want to hang around and keep cutting further. It looks like the hinge was only about a half inch thick. I'll post a picture when I figure out how. It sure does not resemble a barber chair...As for the other, I have trouble not releasing trout that I catch too, but I can usually bring myself to knock it on the head and enjoy the bounty. I would use pine or fir if they were growing on my property. The oak woodlands in the NW are very limited and under duress which is part of my hesitation. I don't know about personifying. Doesn't that imply that the tree in inanimate to begin with? Or that it only has value if it is like a person? Well, I'll search for the other forum. I put out a bunch of want ads in the rural newspapers for abandoned timber frame barns yesterday and will be knocking on doors. Oh, I didn't understand the recipe/egg metaphor??? -paul
