The retention line saved our bacon.

Couldn't tell for sure, was that maple Nick?

 

[bonner1040]

Yes it was

Nick, learn a lesson from that barberchair man. That cut needs to be retired.

Or at least only used when there is a reason for it.

 

[murphy4trees]

sup with that Nick?

 

[flushcut]

Waiting!!!!

Your retention line was set well, by why not put a face in it? It would have gone a lot easier, I think.

 

[CurSedVoyce]

Looked like a Micro face to me on one side.

 

[murphy4trees]

Pretty sure he had a face in it... looked like there wasn't much to face on the far side, due to the split. I like this video a lot because it shows something unexpected... any time something unexpected happens there is something to learn. In this case looks like the damage from the rip caused enough weakness in the grain to make the bbc weaker than the hinge.. could have been a bad cut too..

What lessons did you take from this Nick?

 

[bonner1040]

I am going to edit the video and type up an analysis soon.

There definitely was a face in it and I think it would have barber chaired no matter what.

The audio that you hear is me talking as it was happening. Dwayne was quite a distance away running the pull off of the GRCS. He was able to hear me easily since we were using the helmet intercom systems from rope tek.

Would a binder or two have helped?

 

[MasterBlaster]

I would imagine.

Too much hinge perhaps? However looking at it again, the stepped back-cut loading it fast & hard would be the major cause IMO.

Looks like the retention line was an exellent plan b, that one was just nasty. Thanks for showing it Nick.

 

[bonner1040]

The retention line was plan A. It was pretensioned with a come-a-long and then transferred to a port-a-wrap.

exactly... I just got the tent stakes ground anchor system... looking forward to seeing what it can do...

 

[Tucker943]

Too much hinge. Bore it out right up until there is only enough hinge to get it started in the right direction. A standard bore cut, thin hinge should have been sufficient for that tree.

agreed

Having seen the completed vid (Thanks Nick), I think the stepped backcut caused the barber chair.Maybe if the offset had been alot less then it may not have occurred. With the retention line in place a normal backcut with a nice thick hinge would have worked. That tree was only going one way! Good work Nick!

 

[Jack]

Too much hinge ...

Too much hinge ...

 

[murphy4trees]

That's one of those situations where the retainer line insures that nothing can go wrong and its good to chage some things up and see what happens... after 10,000 hours you might start to get the idea..
