If you need to compete with the hacks out here and low ball everything so that you are forced to one hand saws... well then lets call a spade a spade. If one handing saws is the best way to go, lets make some training videos and training seminars about the proper way to one hand a running chainsaw at 80ft. Sounds pretty stupid doesnt it. There I said my part, now I am open to all of the responses attacking my skills, experience, knowledge, etc.

If one manual suggests to a woman that she must two hand a chainsaw - AND THAT'S SAFE and acceptable...

....What is the response to the man with enough strength in his one hand, to control the saw one-handed better than the woman who has two hands on two handles?

If he truly has the stength to control the saw (that tiny saw) better.

Kickback occurs from a quadrant of the bar tip. If there is virtually no possibility of that bar tip being in a position to cause kickback, where is the hazard, if no risk or hazard is present?

In all the tests I've done 0.18secs is about the best, cracked 0.16 every now and then but unfocused you'll be in the 0.28 secs region.

I have been using a chainsaw for thirteen years, professionally. I have never used the one handed chainsaw tech. on the ground, and never in a tree. But I do almost every time I'm in a PALM TREE. It's a differant animal!

Here's some of the chainsaw "rules".

Dont cut above shoulder height.

Dont one hand.

So you are climbing up the trunk of a palm, encounter a stack of frond and berries and junk ... what's ya choices, if you cut and let things fall then you'll damage what's beneath.

The butts and dead fronds are tough and handsawing is way to slow plus you wont get a neat enough flush cut to the trunk.

Snap cutting, well, good luck.

So, for those people who do a lot of palms I know that you know exactly what goes on.

Speaking of which I have 9 to clean tomorrow including one Canary Island Date Palm!

I dont one hand saws and I :
1. Am not lying
2. Climb just about every day
3. Might, but thats because I bid on the jobs that I climb, and the jobs that I dont bid on but still climb.. my highly skilled co-workers bid on. The highly skilled ones also dont one hand saws, so I guess I live in Perfectville, WI.
As for learning from others, I have learned tons from some of the most skilled and knowledgeable arborist in the US, thus the reason I dont one hand chainsaws. And as for Ekka and his videos, I have probably learned more from him that any other source on the internet. Newguy18, if you want to be Oldguy18 please take my advise and get training from ArborMaster or FISTA. If you are unfimilar with these organizations, research them and they might make you more productive and maybe even safe you life.

As for thier training courese thats quite alright as I am learning from others like Ekka and next year I will be learning from someone who has been climbing for quite some time.I would trust his judgement more than what anyone at arbormaster has to say.

First time was 0.662.Second and third were both 0.832.

The person you will be learning from next year, do they have many years of experience, or one year of experience many times? There is a big difference. The 3 most dangerous guys that I have ever seen run a saw all have been working in the industry for decades longer than I have. Now that I think about it, they have taught me lots.

I have to admit that there are not too many palms in Wisconsin. I have never climbed a palm in my life, so I wont even claim to have the slightest idea what its like working on them.

I really dont want to come across like a jerk. Its just that I have seen first hand what running saws do to skin and muscle and it is not a pretty picutre. I sincerely hope that everyone in this industry remains safe and gets to go home to their families every night.

Is forty years experiance enough?I think so and like I said before I one hand at least once in every tree I climb mainly because I can't get into position to make a two handed cut safley.As for seeing what chainsaw do to flesh and bone I lost a knuckle to a stihl s 10 that I was operating on the ground with A TWO HANDED GRIP.I am quite comftorble using a saw one handed but I always make sure that I am clear of the saw dropping,and in a postion to snap the brake with my other hand in case of a kick back espically when doing the improved jump cut.

Never heared of a jump cut. Please explain.

Sean Freeman · 3rd September 2007, 06:47 AM

I think he's talking about corner cutting, if you do it on smaller diameter trees the reduced hinge will fail earlier and the effect is often to pop the falling stem up and off the standing stem.

You need to use a fair bit of discretion with corner cutting its really a technique from commercial forestry designed to avoid root pulling damaging merchantable timber....reducing hinge width can have undesirable outcomes.

newguy18 · 3rd September 2007, 09:27 AM

Thye improved jump cut is under cutting a limb about half way through the nipping through the sides just a shave before tripping the limb with the top cut.I use it to minimize hinging when rigging when I need to keep the load kinda balanced.It works fine for me.
