Connect a come a long hook into the middle of a rope.

[CraigStu]

I have a 150ft piece of 1/2" rigger rope. When I plan to drop a tree I put one end of the rope up onto the trunk w/ a slingshot and a bowline knot. I pull the other end of the rope to the base of another tree w/ a come a long. This adds a bit of fail safe that the tree drops where I want it to. Problem is that I usually only need 100-120ft or rope. But last week I used the entire 150ft. Tying a bowline into a rope 30 to 50 feet from the end is a pain. Is there a knot that would make it easier but also is 100% easy to remove like a bowline. Or is there a piece of formed metal that I could wrap the rope around (without damage) that includes a metal loop to hook my come a long hook to?

Butterfly loop or Alpine butterfly. https://www.animatedknots.com/alpine-butterfly-loop-knot

Maybe bowline on a blight would work too. There are probably mechanical devices that do the same thing.

 

[logical]

Maybe there is a larger version of this ?

Amazon.com

or use this made for 1/2 rope

[BurtEggley]

go to a tree riggers / sappers website. They should have something

 

[cvairwerks]

Prusik rope grab or a mechanical safety one for fall protection.

Bowline on a bight?

...up onto the trunk w/ a slingshot and a bowline knot.

I guess a "slingshot" isn't what I think of when I think of a slingshot.

That's what first came to mind for me.

Bight

I don't know the reasons not to, so i tie a bowline like that but just treat the bight as the end of the rope, so the whole thing is just doubled up. I haven't had a problem using one that way, but I've never dangled from a cliff on it either.

Bowline on a bight?

Thats my go to when I need a no slip andeasy to undo loop in the middle of a line.

 

[jfish]

I've got quite a few years of rigging, crane and line work under my belt for what that's worth.

I came to say what everyone else said.

My go to is an Alpine, a lineman's go to is the bowline on a bite.

You should try it on a bight sometime!

 

[jubilee]

I’m a bowline man, but in something like your doing I’d use a a hay hitch or trucker’s hitch with a long screw driver struck through it for easy release

 

[Lumpy102]

I'd suggest the alpine butterfly as others have, my second choice would be an inline figure eight.( it is directional) A bowline is a reasonable knot choice, we use it sailing, but never in life safety applications.

Figure 8 Directional Loop

Load-bearing loop in middle of a rope, takes strain in one direction. In fact a strain from the wrong end actually capsizes the knot into one that slides, i.e., it functions as a noose so that the loop tightens under load.

Alpine Butterfly Loop

The Alpine Butterfly Loop provides a secure loop in the middle of a piece of rope. Load can be safely applied: from the loop to either end of the rope; between the two ends with the loop hanging free; or to the loop with the load spread between the two ends.

[whateg01]

Whenever I've used an alpine butterfly in a high load situation, I've found it very difficult to loosen afterward.

We make our early apprentices participate in a "knot tying" competition and we've never spell checked them.

We generally just have journeymen time them and judge their completed knots

When I was an apprentice lineman (1989) I do not remember being timed on knot tying unless it was a lineman rodeo event.
But , yes we had to pass in knot tying.
Being that long ago I don't remember all the knots we had to do.
But some were..
Bowline
Bowline on a bight
Various hitches, half, timber
Eye splice
Back splice
Running splice

Probably more but idr.

We do it as a team building thing amongst the apprentices. Puts pressure on them to learn the knots together and we have created a pretty irreverent "relay" race with the knots, obstacles, one hand and blindfolded knot tieing.

That and we make them give us a talent show...

 

[Cc_windsurfer]

Alpine butterfly is the knot to use.

 

[CraigStu]

I will try working on the alpine and the inline figure 8. I have used the bowline on a bight and the one problem for me is it can get messy quickly since mid knot you end up w/ a lot of loops of rope. I have an ascender for 1/2" rope that I use for going up on the roof but I am not sure what load that can work with.

Petzl Ascension Hand Ascender

The ergonomic design of the Petzl Ascension makes it great for use on long climbs. The toothed cam is easily engaged with a thumb lever.

www.treestuff.com

Most times I actually have 2 come a longs in line w/ each w/ about 10ft of cable. One gets fully retracted and the other usually at least half way so a lot of pull weight. I was hoping something like this could be used but I don't see my use illustrated.

Notch BackBone MINI Knotless Rigging Connector

The BackBone knotless rigging connector is an extremely versatile tool for rigging quickly and securely. If you're working with smaller loads and feel like the original BackBone is a bit over

www.treestuff.com

BTW this is the slingshot. I have 100ft of 1/4" line w/ a weight. I throw that into the tree and use it to pull the 1/2" line up.

Notch Big Shot Throw Weight Launcher

The Notch Big Shot slingshot is designed to launch a throw weight and line over a tree limb so a friction saver or climbing line can be pulled into place.

I'd bowline on a bite or triple bowline.

Triple bowline?
Can you show the class (me) of what you're referring to?

Its sort of a cross between a regular bowline and bowline on a bight. Instead of capturing knot with the bight you tie it as you would a regular bowline (with line doubled up) but form a third loop with the bight.

Hmm. Ok.
I can't see a use for an extra loop.

 

[cgrutt]

Perhaps not for putting tension on a tree but it is a useful knot nonetheless...



I realize illustration is tied as bowline on a bight

I see 3 loops on the man, 2 legs and chest/back.

The diagram only shows a bowline on a light, (bight) stupid ai can't spell) unless im missing something. If you stop at step 2 and use that loop then oof, looks like it would hurt, a lot when it tightens around your chest.

Eta. Just read the last sentence in your post.
Still can't see it though.

I need to practice tying that knot. Can you send Jennifer over? You know for practice and science and stuff. Thanks.
Not sure how that guy got through that. A true professional right there. Focus.

Lol

Ok. I can see it now.
Bowline on a "bight" was confusing me.

It's just a bowline with a double piece of rope.
It doesn't have a bight.

Lol. The loop formed by doubling the rope over is the bight.

 

[VietGnome]

That 3rd loop is just the tail. It can be used in a pinch for a harness and chest strap. But if a regular howline has the single tail coming up into the loop, a triple bowline has a bite (loop) as a tail coming up into the two loop, if that makes sense.

I like it because it can be tied around things in typical bowline fashion, while you can't do that with a bowline on a bite

The position of a Prussic can be easily adjusted if necessary. And it's easy to untie after the load is removed.
