Al asked about a flat cut in another thread.

First off DON'T DO THIS, YOU HAVE NO CONTROL OVER WERE THE TREE IS GOING TO FALL!!! There is no hinge wood or face cut.

You start with a with high powered saw 066 or equivalent size. 090's were used a lot for this also. The bar only needs to go half way through the tree. So a lot used 20 to 24" bars.

You divide the tree into fourths or thirds based on what root Buttresses are on the tree. You then cut between the Buttresses and use them to support the tree. The last cuts made are to release the Buttresses. For the most part no wedges are used. You cut using the feel of the saw to keep from pinching it. As soon as you feel it pinching you pull out and go to another spot. Alot of folks back cut using the top of the bar so the sawdust packs into the cut helps hold it open.

Here is Al's picture for reference.

Unlike what Reddog explained, we always put wedges just behind the side buttresses to get it to pop off the stump.

I think they mentioned in another thread it's so that there's no fibre pull on trees where the wood is valuable.

Thanks, I guess I'll hunt that one up right now. You're alright for a Canadian. I don't care what Stumper says.;)

can you draw it for us?
The crayon shows up on my screen. :D

Think of it like cutting a stump off as low as you can before grinding it.
It is about the same thing.

I will not use it. I would rather cut a shallow notch on a veneer tree with a thin hinge. At least you have some control.

So is this cut strictly for preventing fiber pull? Or is it also for heavy head leaners? Thanks.

I can see where this cut would be benificial if you were mining for figure which is usually in the bottom 6 to 10 feet of the bottom log.

With that assumption,this place I live on was at one time owned by a family of high end cabinet makers who do grade A work,excellant.The 25 to 30 some acres of woods was sub divided and sold off in the early 70's .Before they left they snagged a few of the good lumber trees but not all.

It is also my assumption that some if not all of the white oak in this house was fabricated by them because their sister owned this home at one time.

I'm not a lumber man in any way form or fashion.However I do know that a prime log with nice figure is worth more than the rest of the tree.

Do a search for figured cherry,hard maple or walnut gun stock blanks and you will see what I mean.

I've never heard of this cut before this but from reading the technique I'd say it's not for heavy head leaners due to it's unpredictable nature and the risk of getting pinched.

To reduce Fiber pull.
I know a couple guys that skidded on jobs that were cut this way. They hated it. If the wind was not blowing trees would be left standing on the stump. They would have to back into them with the skidder and push'em over.
Also a lot get hung up from no control on were they are going.

Sounds like craziness to me, but if you followed Jer's suggestion I suppose you might not get eventually killed. Your saw is a different story :D.

I was thinking that it might wreak havoc on the residual stand. More of a high grading technique I guess.
