Great site, I've been looking on here for ages but never got around to joining.
But thought this might be useful for those who want to make these in a hurry out in the field. Please excuse any dropped links or images, first post on the forum!!
Start with a simple loop made with the stopper knot of your choice (for this example I've just stuck an overhand knot in a bight on some cord I had lying around.) Pic 38.
Then form a loop by crossing/twisting the end of the bight. Pic 39.
Pull another bight through it. Essential tying a marlin spike hitch at the end of the bight, Pic 40.
feed cord through hitch, until legs are even and hitch is right at the top of the bight. Pic 41.
Loosen the loop of the marlin spike hitch by sliding it down one leg. Pic 42.
Pull stopper through loop (basically this is the Marlin spike for the knot) and tighten hitch around cord. Pic 43.
I'm thinking of ditching all my carabiners in favour of these. So that will be one on the end of each tree hugger and instead of using clove hitches around carabiners on my single line, I'll use trail debris to make marlin spike hitches on the line and use the nacrabiner to hang off of these. Will post pictures if it works and to make it a bit more clear.
I already use them on the tarp to secure my tarp tie outs to my Penthbury Prussiks on the ridgeline, so I can sling my Tarp however I choose.
Keep up the good work people!! Once again love the forum.
