Though many saw hands scoff at the practice as being sissy, the

est
way to fell such trees is to bind the butt (immediately above
where the top of the notch cut will be) with heavy duty nylon
webbing (ma

to handle the extreme forces involved) before starting any
cuts.

This, too, is news to me. *I'd appreciate any more inofrmation
you could provide as I'll be doing a lot of cutting here in the
next few months.

I probably should have used the term strapping rather then webbing.
The type of nylon web strap that log truck drivers in many areas
use to bind down their loads is what is used. Any good saw shop in
an area where there is much commercial logging going on could make
one up for you in a size to handle the size trees you will be
working with. *It should be used on any tree with a very heavy lean
(especially hardwoods) or one with a very unbalanced crown (heavy
in the direction of fall).

The

timber fallers." is quite true.

Much to think about.

Hi, everyone. *Wolfgang - thanks for that story, entertaining and
thought provoking, as always. *And thanks, Bob, too, for sharing from
your expertise.

Please forgive this question - I'm not too embarrassed to say that I
don't quite get the mechanics of this accident.

Is the issue that part of the tree from *below* the intended cut gets
split along with the main part of the tree and that's what swings up
with bad potential results?

I can't speak with any authority to what happens generally, but in
Karl's case, and as I have seen before, the split occurs (or, starts,
anyway) right at the place where the back cut is made. The
illustration at the site you pointed us to is a bit misleading in that
it doesn't show the notch, which is precisely opposite where the split
has occured and where the sawyer has met his doom. Of course, the
result shown can also happen without a notch having been cut at all
(as shown) but common practice, as far as I know, includes notching on
the side toward which the tree is intended to fall. However, this may
indeed not be the case where trees lean severely and where they are
intended to fall in the direction of the lean. Obviously, cutting
opposite this direction will produce the intended result without a
notch.....but the possible consequences (with or without the notch,
for all I know) are now all too obvious.

In any case, the answer to your question would appear to be no.....the
split starts at the backcut and moves up through the trunk.....or so
it has always been in my admittedly limited experience.

Incidentally, I've seen in happen even with small trees and without
any significant lean. And, unlike what is shown in the illustration,
the busted end does not necessarily always simply lever up. It will
often kcik back as well. Imagine the broken end actually moving
toward the sawyer so that even if he were standing several feet back
from where he is shown in the illustration. Depending on
circumstances, he might still be toast.

And, of course, it is not just whole standing trees that are
dangerous. I narrowly missed being decapitated myself by a four inch
cherry branch last spring. The tree was already down......dropped by
a much larger oak that took several other trees with it. The cherry
branch was obviously under tension.....had a significant bend to it.
I misjudged the angle of the bend or the forces at play or one thing
or another. I cut it and felt the wind whizzing past my left ear
before the import of what had just happened (or not.....depending on
point of view.....I'm glad to report that I'm in a position to take
the latter) registered in my brain or Becky's; she was about fifteen
feet away, waiting to load up the sawn firewood.

Any way you look at it, wherever the sound of a chainsaw penetrates
(or any other saw) there is danger aplenty.

But then, the same can be said for any place that such sounds never
reach.

giles
who has known all his life (on a more or less intellectual level) that
one way or another they WILL get you in the end. it's just in the
past few decades that a more personal and visceral point of view has
come to hold sway.

p.s. Karl died about 2 or 3 a.m. on saturday.


WTF does this irrelevant babbling about felling a MF-Tree have to do with
FISHING?????

I know, It's the 'old woman' in you that just can't resist the opportunity
to go on, and on, about a nothing topic. All you need, you Old Bitch, is
just the least bit of an chance to start up that super charged motor mouth
of yours, and spew out from here to eternity!

Babble on you crusty old witch!!
