Hybrid high strength lanyard
I am thrilled with this one
.
At first glance it may not be apparent why, as the lime green cord is awful and the speckled appearance just detracts from the weave, which is a bit too short. This small length of green is all I had of reasonably soft cord. Paracord in black, grey and red is arriving next week
.
Nylon's long term chafe resistance, particularly when wet, for sections where it passes around small diameter bails (are all small attachment points called "bails"?) concerns me a bit. These lanyards are often holding torches and knives of value, even if only sentimental.
A couple of days ago I suggested that maybe a piece of
Spectra fishing backing line could be incorporated as a
safety measure. I decided to take this one step further and try making the portion going around the attachment point entirely of
dyneema.
Attempt one was via a spliced loop I made in 3mm
dyneema. Too thick. So I made the next one with a straight portion dyneema that would need to have tails buried if I wanted to conceal them.
I then had two choices: incorporate the dyneema in the weave or leave it simply as a backbone.
I did not incorporate it into the weave for the following reasons:
- It was not needed for strength
- The weave would then be slippery
- Using part dyneema for the weave would mean the woven material would not match
- No dyneema in the weave would mean the braided portion was free to slide, even if tightly woven on the "backbone" of dyneema (this thought was sparked by Uncivilized's comment of making a small Turks
Head and then sliding it up the lanyard to help keep the cow hitch connecting the lanyard to the object in place)
To hide the tails of the weave I wanted to pull them into the weave itself, as BelizeSailor had done.
Several attempts where made to find a weave that could be started and finished in a pleasing manner. I ended up starting the weave with "Brion's Button" (I am calling it this to distinguish it from the hundred buttons in the ABOK) and then feeding the dyneema through the centre, then weaving multiple Crown knots around the dyneema plus four doubled over "pulling cords" of whipping twine, which would allow the tails to be pulled back. I finished with another Brion's Button with the dyneema passing through the centre again.
The weave was a huge success. The dyneema passes absolutely beautifully right through the Button. Only problem was that the weave was two tight to pull all 4 tails through. So I undid it all and repeated the weave with 4 bits of the green line laid along the backbone so that the
core of the weave would end up a bit wider when the 4 bits were pulled out at the end, leaving room for the tails. Perfect!
The weave is tight on the dyneema, but the dyneema is so slippery that the weave can still be slid. This means the small loop at the end can be opened up to any size, cow hitched to the object and then the weave pushed right up against the cow hitch, making the lanyard useful for a variety of objects.
I wanted a big loop at the end, as this acts as a
safety line. It is so easy to drop objects when hands are wet and cold and the
deck is pitching. The loop also allows a temporary snap shackle or carabiner to be added whenever needed.
I could have spliced the tails of the dyneema at the end, but I wanted to leave the loop thin and pliable. It just sits beautifully against my wrist as is.
I could also have finished off with just a simple Diamond
knot and cut off the ends, but I made it a bit neater by tying a Double Lanyard
knot (for length) with two "pulling cords" of whipping twine through the centre, then tying Brion's Button. The tails of the button were pulled through the Double Lanyard (it was super tight, but could be done as dyneema is slippery) and cut off.
If you don't want to fuss with making any Buttons then just skip them. The central weave can be just about anything you want. The weave BelizeSailor used would
work well, but there are dozens to choose from.
Next week I will make one with the central made from two colours of paracord (maybe grey and black) and have a play with a few more weaves.
This was the final result:
