Anyone ever use one of these as an attachment point? Techniques? The edge of the metal seemed a tad sharp, and i'm wondering if what i'm thinking about makes sense... Short of putting a couple of pieces of duct tape on the edge, anyone have anything else?

Is the tower on or in use? If you dont think it would get noticed, you can attach some other type of material that is stronger and resistant to cutting (ie a chain, strong rope, coated metal cable) and then static line off of that. I wouldnt screw with a sharp edge on a bridle or break cord.

Make a carry with you system. Attached is the best type cwy ever devised, made and tested by me.

Why even go off the horn? You are standing on a perfectly good platform that is grated. Tie off there.

exactly what i was thinking about, only i was worrying about leaving (or potentially) a trace of my existence there. I use a nylon tube when rappelling to protect the rope from the edge of a cliff...kind of what i was thinking about, but how to do that and still take it with me when i go?? Hmmmm....i may have to do some engineering tonight.

That said, i am curious if anyone has ever tied off to one of these bolts....i mean they're ubiquitous! (yes, i've been pining to use that word) Surely they'd be stronger than 80lbs, right?? I'm assuming that they were put there to help put the equipment in place.
p.s. yeah, this tower is dead as a doornail! weeeeee!

Are you planning on going off the top of the horn? If so, why not tie off to one of those bolt heads that are right at the top?

Your mentioning of climbing and tape made me think of the texas rope trick. I've given absolutely zero thought to whether this could actually be adapted, but it could be something to think about.

Or it could just be reinventing the CWY.

Go PCA or HH...

this one doesn't have anything at the top of the horn. guess they must've taken them off or something.
If not the top of the horn, at a 45° angle from the deck.

I meant the bolt heads that are in the picture you attached. Wrap the break cord or the cwy around the bolt head, then lay it over the top the horn.

use some tubular webbing.
leave it there.
noone will notice or care.

 

i doubt youll be able to paint webbing.
not to mention totaly unnecessarry.
cable is silly too. 1inch webbing is strong enough to lift you car twice.
its an old longlines tower, not a 2000 foot broadcast tower.
you can probably park at the base, setup the grill and cooler and dayblaze away.

have fun.

Dude, you are re-inventing shit

Like Pikey said, you are already on
a perfectly good platform, why go
up on the top off the horn?

Didn't I send you the video of me
doing a Static-Line from Wanda?

All you need is a foot of break cord,
some dacron optional, and definitely
an understanding of Occam's Razor.

how tall is this thing?

remember to think about what your back-up pc will drag across (if used).

wtf do you mean" if used."

thats been settled over and over. ALWAYS USE A PC.



if someone has a good reason to not use a pc, then they probably know how to rig a static line.

surely they are, BUT a standard one loop static-line system with 80lb test break cord generates at least around 160lbs of force before breaking

I'm not going to bother explaining why because a lot of posters here just cant grasp the basic physics involved, so suffice to say, before typing a reply to this saying something like: 'but it's a single piece of breakcord tied into a loop!'

go and pull your single loop staticline system to breaking while measuring the force and it will be obvious that it takes much closer to 160lbs than 80lbs

also don't bother quoting some book on knot strengths to me, test that too, it doesn't make much difference in this case

all of this reply not directed at you, but at the type of replies that this post usually gets

thank you

PS - 160lbs is just fine, 80lb break cord is the right tool for the job, back-up loops are always a good idea.

Not trying to re-invent, Tom. I just saw what looked like an interesting attachment point and wondered if anyone else had used one of these before. As it's 230' from the platform, there are better exit options. Like i said, just curious whether anyone uses the bolts as tie offs.


In engineering, Occam's Razor is used only as a rule of thumb, not an irrefutable principle of logic, and can never be used as a scientific result.

ALWAYS USE A PC.

take a deep breath.
relax.
I know you understand English better than that.

placing a pc on top of an object, where it does not dangle, is asking for it to catch something and rip it apart. a torn pc does very little good.

the anchor spot is on top of an object. I wouldn't place a pc on it. I also expect there is a far better place to tie off.

ok wwarped, ill assume your one of those guys who just likes to argue and takes the opposing position regardless.

thats ok.

let me spell it out for you.

take a piece of 1inch tubular webbing.
tie into a loop with a water knot
girth hitch said webbing to attachment point in op image.

noone said anything about leaving a pc on top of anything or allowing it to drag.

dont be ridiculous.

here is a hi-tech diagram.

I think it's you who like to argue as I intentionally do NOT offer much specific advice. I try and leave it open for people to make their own decisions.

you however, challenged my bland comment and still apparently don't see any value to it.

I tore a pc up pretty bad s/l'ing a similar object. the mesh has all sorts of red paint on it. your diagram may NOT be what the jumper intended at all. there are ways to do it right, and ways to do it wrong.

after spending time on those style A's, I'm confident there is a better place to tie off. one that would permit a cleaner path for the pc.

feel free to continue to argue with my posts.

guys, GUYS!!!! chill out!! enough already!!
In my original post, I was merely asking if anyone had used this bolt as a tie off. I saw it a while ago and was curious. The object pictured is high enough to go hand-held, and that's what common sense dictates. I suppose i was curious about the bolt as a tie off for lower freestanders, where s/l makes more sense. Again, I ONLY wanted to know if anyone had used one of these bolts. The thinking is that on something fairly low, the added +/- 5' might come in handy, or at least be a psychological boon.

...Though i do really appreciate the high tech diagrams. MS Paint RULES!!

Not sure what your experience level is, but 230' isnt something to take lightly if you plan on FF it.

I get the impression you are pretty new at this (feel free to correct me if im wrong) If it were me, I would probably SL it first, to get a feel for everything.

Your experience may vary!

No, you're right on the money as far as experience goes. Not trying to portray myself as something i'm not.
I guess it would be better said that at 230' static line or pca isn't absolutely mandatory, right?

That said, i'm always, 100% of the time going to go for the safest option, be it s/l, pca, h/h, f/f, or climb down.

Yea.
Every one of those I've been off have a small flange with a hole on the outside right below the grate. It's nice because the PC is down and out of the way. You have to go from the middle though.
