Split Spar (suprise!)

[ QUOTE ]


After seeing this, I think the best choice for a lanyard adjuster is one that will allow adjustment while under tension. It seems that a rope grab can work against someone in a situation like this...

Makes me think of going to a friction hitch on my steel-core flipline, in addition to using one on my rope lanyard.


Additionally,
That small prussiked clip-in loop (tech cord and the like) that people put on their lanyard, in order to choke the stem, SRT style, is an easy way to be lanyarded in, but with one's pelvis out of the circle formed by the back of the harness and D-to-D attachment of the lanyard. In a stem splitting situation, it would be better to choke the snap or 'biner to the lanyard (with a bit of chance of cross-loading), than getting squashed within the loop.
 
DANG!!! Thanks for sharing this. And thanks for having the frame of mind to get a good (smiley) picture of the situation to share with us!

I wouldn't been tempted to rig one half off the other. I have a feeling that other trunk came into the equation.

If you had a steel flipline and a micrograb, how would you get yourself out of it?

Gord, how did you get the rest of it down after it split??

how scary is that. it's like once you move your lanyard the piece splits off and crushes something. damn. i woulda had my groundie send me up the rigging l;ine and tie it off under where my next cut would be. piece it down and get the heck outta dodge.

Thanks for the pix ... it's great to see that 'smile' (SEG) on your face in that first pic. I like to use heavy cargo straps on a tree if I'm worried about a split ... I would NOT have known strap that one - but we don't have Bigleaf Maples here. Picked up some great tips from your thread, thanks again.

It was actually really stable after it split, I lanyarded onto the back slab and chunked it down to just below the split (yes twice as many pieces, ha!) and was able to fell the last 15' or so feet. I tried pushing it apart where it initially split but it didn't want to go any further.
 
I have heard popping sounds from many alder and maple spars, but never really thought something like that would happen.
Had the tree recently been through a high stress event of any kind?
Will this change any of your work habits?

Thanks for posting, this is one of the best ever... glad you're safe!

The ring on the friction saver will release the hitch unless by some freak thing the hitch goes through the ring which could happen with the thin cord.

A tautline or blake's hitch might be certain not to allow the hitch to pass through.

Truth be told, I don't think that I've ever actually tied a Blake' hitch, for better and for worse.


Looked like 8mm hitch cord on 7/16" would go through the small ring.

WOW!! Thanks for posting this.
I haven't seen or heard of this happening before. Glad it happened slowly.
Has anyone else had this happen?

yep! White oak with a pretty solid lean. I was ok to but had a moment of OH CRAP! when it split. I was tied in to another top at the time, I was able to think quick enough to release my buck strap. NOT FUN! Nice pic by the way, I am always wishing that I remembered my camera.
 
I've had a few heavy leaning black locust do that to me as well. Not split apart quite that severely, but you could hear it cracking, and it did seperate down the grain when chunking down wood.
 
SO glad you're ok man. I've been begrudgingly changing my spar work habits to include this possibility but never thought to use my flipline in that fashion (on the center point). I really like to use an AFS for spar work. I've never had to deploy the technique of "opening" it up but I always stay ready to do so. Great thread you guys. Thanks to all of you.
 
Thanks. Kiteboarding is easier than people think. I learned this last summer and was hooked after my first session. No motor. Just you and the wind. Oh and no more lift tickets if you snowkite.
