hello, long time periodic reader, possibly first time poster, can't remember.
these pictures illustrate a way i've found to very simply and quickly
make a sling from any strong cord, starting with sheepshank knot,
slipping long ends through the loops trapped by the half
hitch...resulting in sheetbends at each end of the pouch.
then you inch cord back and forth till it is tight and balanced as you
like, currently i like to have the central cord of the pouch just a
little bit longer to give the pouch a little bit of concavity.
to finish you'd take a second thinner cord of any type and weave it
amoung the three cords, or you could make a more solid basket pouch by
adding two more little cords as ribs in the spaces between, giving you
a woven pocket of five ribs.
with about 5 feet of 4 to 7mm static line and a shoelace i can make a
sling i'm happy with in about 15 minutes.
i like this design as it's easy to make, strong and seems to hold
stones very securely, but this is a newly discovered design for me, i
don't really know it's strong and weak points yet, just wanted to
share it with you fellow enthusiasts.
here are the pictures of the sheetbend/bowline based sling i've constructed:
you can see my friend's nose, an accomplished string theorist, in this picture.
now taking them apart, you're seeing either a bowline or a sheetbend knot depending on how you want to think about it.
the two long working ends come back out of the two loops to show that it started as a sheepshank, which is just a Z semi-secured at each end by a half hitch.
...or as i like to say it,' loops and cursive Es'.
as to the cautionary tale, many years ago when i was 12 or so a friend
of mine and i were slinging, i'd made both of our slings and we were
happily smashing rocks against a cliff face several hundred feet away.
the two of us stood about 50 feet abreast from each other and fired on
the cliff ahead of us.
we were using a helicopter style (really a home baked figure 8 based on cracking a whip) and had leather pocket pouches.
to make a long story short one of my stones slipped from it's pocket
as it passed directly behind me, my friend bent down to pick up a
stone just as my misfire went hurdling twards his side... my stone
collided with his head, he stood upright, screamed and fell over on
his back and did not move.
by the time i could blink and run over to him he had gone white and
had swelling at his right frontal lobe the size of a cue ball.
he came too but was incoherent and screamed for several minutes... we
iced his head and gave him asprin, thankfully he survived and had an
appetite for fast food 2 hours later.
his rightfully irate parents x-rayed him and found that his skull had
been slightly cracked.
we remained friends, even slung together a bit but were always more
fearful as we did not understand any safer methods of construction or
release.
i have always been horrified at how close i came to killing my friend
and grateful that it did not come to pass that way.
i didn't have but about half my energy at that point of the windup,
the soft sandstone nodes we were using could be crushed between our
fingers, and i missed his temple, hitting the stronger, rounded dome
of his forhead instead... but why he had to bend down right then i'll
never know.
a true story guys.
