Setting climbing-anchorage on straight/smooth spars..

[ArborOdyssey]

So far as I know, a TreeSqueeze is the only product sold for cinching a spar so you can set a climbing anchor on a spar, in fact I've seen adverts for choking rigging slings that explicitly mention 'not for climbing' for instance I've never seen someone using a TEC whoopie as a climb anchor.... What do you guys do when you need vertical anchoring on a spar? 

 

~~~

 

My goal here is two-fold,

1- Knowing what is/is not an OK form of anchoring climb lines on spars, and

2- Make such an anchor (already have a 'Treesqueeze-type' lanyard for this however I've got some xtra "Lrg x ring"s (#2's) collecting dust and love splicing TEC, was thinking to use 1 (making a boomer/double-head would be pointlessly redundant on a climb line, 1 lrg-x-ring, ~30mm, is far wider than a couple o-rings, ~24mm) to make a diesel 'spar-anchor' but didn't know what's safest, what's "officially approved")

Thanks a lot for any insight on this, I've heard of sling-slippage but have never seen/experienced it but I'm presuming that's the logic behind not using a whoopie as a climb anchor, but when setting anchorage on a slick spar I'd think a whoopie would be far more secure/stable than a TreeSqueeze (the whoopie would be inclined to stay in-place when not under-load, a TreeSqueeze is depending upon load on the line to hold its form..)

Not quite sure what you mean. I generally use a cambium saver, have use a choked sling and carabiner also. There's usually a branch stub somewhere you can use. You could cut notches in the spar so it bites on something. I have never felt the need to buy anything specific.

A sling choked around the stem, carabiner  and micro pulley will also do the job just not retrieveable from the floor

I mean if you were going to set a climb anchor on a telephone pole.. You could use a treesqueeze and ascend/descend such a system safely - I'm asking what other configurations/anchor-types can be used so you could, say, use a telephone-pole as your personal "gym" for ascending/descending practice (w/o ever worrying about your anchor-integrity)

 

[^not what I'm planning to do but knowing ^that is all I need/am looking for ]

 

You say:
"I generally use a cambium saver"

On a spar?  Are you meaning an adjustable-cambium-saver?  Adjusted so it's ~75% the diameter of the spar, one end tossed-around the spar, and then your climb-line's pressure on the rings chokes the c.saver to the spar? 
(Honestly this seems about the same as a Squeeze setup, it's only that this could roll much easier... also I'd swear I've seen "for crotches only" on such anchors, I know my eye&eye rigging-sling is "for crotches only" although it 'works' choked and probably got more use that way[sling is no longer with us])

 

 

" I have never felt the need to buy anything specific. "

Well this'll be "a steal" insofar as that goes as it's just a tiny bit of cordage to make a sling, already have the 2 'large' rig-rings (had to remove from rig kit as they don't allow spliced 5/8 rope to pass only XL rings/Safebloc do) and was already ordering TEC anyways so will literally just be purchasing a lil extra cordage and that'll be my "purchasing" for what'll create something I'm sure would be $75 or $100+ (but that's just arb-retail, I make my own stuff my "Squeezer" has a higher ABS than a $200 "TreeSqueeze" ;D )   Plus I enjoy splicing, it's not "factor-in your time-value for the splice" it's "neat I get to splice some TEC while watching a flick tonight!"

The only time I am attached on a straight spar is during a dismantle. Otherwise i am tied in higher up through a crotch, when doing reductions.
On a spar doing a dismantle i just have my flip line and rope round it and chog it down in sections. I generally free fall more than i rig, as I am pretty good at doing a snap cut on a section, break it and throw it accurately into a drop zone. I used to rig more but more confident as years go by.

As others have said... I’ll only use this method chogging down a stem. I usually choker the spliced end back into the main line, either with a running bowline or a Krab if I’m being lazy (usually) I’m always very careful not to stress the Zigzag but I’m confident I can get down quick in an emergency. I’m sure the ‘police’ could take issue with this if they wanted, but it works for me. If I do need to go back up I have my lanyard and spikes.

Multisaver, as others said it's for dismantles only so need something easy to slide when unloaded.

[MattyF]

SRT alpine on a ring or pinto and it retrievable , great for knocking out big lumps or a back up chogging down.

[Rich Rule]

As Matty said or a running bowline.

Running bowline on dismantles, descend on single line if needed, a wrapped cam saver works if you keep a bit of weight in it. I borrowed a multisaver on one large pole one day, was handy and could see advantages, pretty cheap and could pop back up stem after lunch. If you're descending a single line on a friction hitch don't forget to put a munter in a crab on your harness or fig 8 ?
