Chain snag

[Cloud9climber]

Hi there, I'm fairly new to the world of arb, been climbing solidly for the last 4 months now. I was taking a rather big limb of a black pop the other day when the chain got snagged in the cut and took the saw with the limb! Quite scary really luckily I wasn't too high and it pulled on me and swung me round! Is there any reason for this? Is it certain trees its more prone to happen in?

 

Cheers

sounds like you used an outboard step cut?

Yes that's correct, have I done the snap cut wrong or would I of been better doing a inboard?

 

Thanks

Out boards on big timber will snatch the saw a lot of the time. In boards will do it sometimes too..... If it is big and you are free falling, get the cuts to match top and bottom or even sink cut them. Can always get out further and take them smaller.

Fast sharp chain, under cut, as much as you can without it sitting on the bar, then finish off with a top cut SLIGHTLY behind the bottom cut. It'll 'pop' off

Depends on species , time of year and size of limb aswell!

On Big Beech I match the cuts.

Birch it doesn't matter, same as green Elm, it's chewy and doesn't jump off.

If sycamores in full leaf , look at it wrong and it can snap quick, but it can be hinge cut quickly and the leafs act as a big sail so lands flat if your awesomely skillfull or just lucky:)

If your ever in doubt, unclip the saw..

Or rather than un clip it and possibly lose it, attach it to another branch rather than your belt

Fine for girly limbs, big tough Scottish limbs you unclip.

I climbed for years with an unclipped saw, you soon learn to hang on to it and do better cuts.

Thanks for all the advice! Since it happened I have been quite worried when taking off some of the bigger stuff. I will take onboard the advice and i should be fine do the tool strops have a certain breaking strength?

 

Thanks again!

Yeah tool strops should break away under a heavy load.
