Here's a quick easy way to turn your whoopie slings into a pair of utility constrictor ropes.
Here's a whoopie sling, spliced to a strap, with a whoopie hook.
Pull enough out to tie a knot...
...and cut
... pull it out
...cut off the tail
DON'T FORGET TO TAPER!
I've read others having trouble cutting amsteel, I just hold the strands with my thumb, and pull down on the other side. Works great...
re-splice your hook (if your only using a fixed eye, you can skip the step of pulling out the splice, you can make a fixed eye with one end of the cord, not so easy with hardware though...)
pull the end back through the constrictor....
re-backsplice the tail
Start the safety knot...
...finish the safety knot
backsplice the end (ok I guess now you've finished the knot)
Here's your finished UCR
all wrapped up
Any questions, feel free to ask...
