What Knot

[ivan]

hi

Guys Im just wondering what is the best knot to rig up some dyneema shooting line onto the shaft and muzzle. The only one I can think of using at the moment is the standard bowline.

What sort of knots do you guys use mainly spear end to attach the dyneema.

cheers

Sorry, know this isn't much help, but I think the bowline is probably your best bet.

hi

Yeah if I cant find any others I will just use a bowline.

In the Rob allen catalog they seem to be using some special knot kinda looks like it is more streamlined.

cheers

I like the perfection loop for the pigtail end of my shaftlines. For tieing to the shaft I use a three turn uni-knot. http://www.netknots.com/html/fishing_knots.html
I tighten them down with pliers and if they don't turn out perfect they get cut off and retied, even if it means starting over with a new length of line. I'm using monofilament and haven't tried these knots in dyneema, but at least the link may be of some help.

Thanks mate, that Uni knot is easy to do after reading the instructions but It pulls up tight on itself which is a big no no. I tie my knots to the last hole which needs a loop cos when you push the spear into the mech the knot will get caught unless it has a loop.

hi

Then again just read the perfection loop and it looks like it'll work.

A figure eight knot works perfect. It is commonly used for nylon sheathed climbing ropes. It leaves a nice loop as well.

hi

The dyneema is still coming, do you reckon the figure of 8 is okay with dyneema.

cheers

I did perfection loop but it seems the knot is bit bulky for my OMER's muzzle.:hmm

 

[Mattedhead]

I am using the figure 8 knot on the dyneema that extends from my shock cord. It fits well on the muzzle of my OMER 116. The knot has held up very well on fish up to 80 lbs. It is also pretty streamlined.

Where is that figure 8 knot?????

 

[Murat]

I tried both bowline and perfection loop. Both seems same to me they both seems reliable and strong but bowline is less bulky so in my opinion bowline is better for spear.

Step 1

Here is the figure eight:

Step 1: Form a single figure eight in the end of the rope and feed the tail through your harness. Some harnesses require that you feed the rope through certain straps. When tying in, I like to feed rope through the same harness straps that the belay loop occupies (not pictured), others prefer to use the belay loop (as pictured). Still others prefer to tie into a steel locking carabiner, or two aluminium locking carabiners, gates reversed, which have been clipped into the appropriate harness straps. There are pros & cons. Consult your harness manual for the recommended tie in point.

Step 2

Steps 2 & 3: Rethread the figure eight, following the same path as the first. Pull the knot tight (though some climbers prefer to leave it a little loose to absorb force from a fall). Make sure you have enough tail, as the knot will slip a bit when loaded. Check the knot by counting "two", "two" & "two", for the three visible doubled strands. Ensure they each are lying flat and not crossing over themselves.

Thanks dude. Isn't this too bulky for spear?

 

[Mattedhead]

That's climbing rope, I just figured it would be easier to see in the pic. With dyneema it is really streamlined.

 

[SpearSlinger1]

I agree with Mattedhead. The figure 8 is a nice, trim, streamlined knot, it just looks bulky in the picture because it's tied in climbing rope. Any concerns about the knot slipping when used on a shaftline can be solved with a drop of Super Glue.

hi

Cheers mate that knot looks slick
