Can I glue Dyneema?

[Kukri]

Like most amateurs I doubt if I can get the button knot in a soft shackle tight enough.

Can I go to Plan B and put a drop of super glue on the knot?

If i am on the boat, to tighten mine I have a small "G" cramp & sometimes mole grips, & I just cramp the end to the mainsheet track & tug against that with the marlin spike. At home I put the end in a vice & tug.. It soon tightens & I have never found it an issue
Have you actually tried one, or are you looking for a problem that does not exist? You might be better than you think

Not being on the boat I am probably over thinking it. Thanks

Haven't you got a foredeck gorilla or two for that sort of thing?

Technically, “foredeck” is not a job for gorillas. A good foredeck man is slim and lithe. You keep the gorillas in their pit.

I have a rugger playing medical student, but only in his vacations!

There's lots of Gorilla Glue about.....

'Cyanoacrylate' or superglue is rather brittle. Read this and keep some acetone handy for when your fingers stick to your 'soft shackle' and anything else within reach.

So he plays rugby and studies medicine for relaxation during vacation - that's unusual enough - what's his day job?

I have a medic granddaughter who has spent her labs in the last few months glued to a computer screen - its all a bit of a worry. Maybe I should have taken Zoidberg's advise - acetone.

I agree superglue would be too brittle for rope. Having stuck myself inextricably to various items/materials, I now use the gel formulation which is much more controllable.

i think I have found a way to get a diamond knot really tight without using a winch. Make the knot and work it tight, then take two pairs of pliers, grab a strand with one pair and rotate them against the other pair - in effect using them as a Spanish windlass.

The third picture shows how much the knot tightened up - when I started the double overhand knots were tight up against the diamond knot. I got seven centimetres of 5mm dyneema out of a “tight” diamond knot.
